The “common” set has several variations (DO Doubles, TR Triples, etc.), but these are the ones that are regarded “official” and are the ones that are used here at Baseball Almanac, among other places. Did you know that the National Association (a non-official league that gave rise to the National Leagueofficial )’s statistics were destroyed in a fire in the early 1900’s? Major League Baseball organized a Special Baseball Records Committee in the 1960s to examine the irregular records that had been kept previous to the 1920 season.

Definitions of Baseball Terms
% Inherited Scored A Relief Pitching statistic indicating the percentage of runners on base at the time a relief pitcher enters a game that he allows to score.
1st Batter OBP The On-Base Percentage allowed by a relief pitcher to the first batter he faces in a game.
Active Career Batting Leaders Minimum of 1,000 At Bats required for Batting Average, On-Base Percentage, Slugging Percentage, At Bats Per HR, At Bats Per GDP, At Bats Per RBI, and K/BB Ratio. One hundred (100) Stolen Base Attempts required for Stolen Base Success %. Any player who appeared in 1995 is eligible for inclusion provided he meets the category’s minimum requirements.
Active Career Pitching Leaders Minimum of 750 Innings Pitched required for Earned Run Average, Opponent Batting Average, all of the Per 9 Innings categories, and Strikeout to Walk Ratio. Two hundred fifty (250) Games Started required for Complete Game Frequency. One hundred (100) decisions required for Win-Loss Percentage. Any player who appeared in 1995 is eligible for inclusion provided he meets the category’s minimum requirements.
BA ScPos Allowed Batting Average Allowed with Runners in Scoring Position.
Baserunners per Nine Innings These are the hits, walks and hit batsmen allowed per nine innings.
Bases Loaded This category shows a player’s batting average in bases loaded situation.
Batting Average Hits divided by At Bats.
Bequeathed Runners Any runner(s) on base when a pitcher leaves a game are considered bequeathed to the departing hurler; the opposite of inherited runners (see below).
Blown Saves This is charged any time a pitcher comes into a game where a save situation is in place and he loses the lead.
Catcher’s ERA The Earned Run Average of a club’s pitchers with a particular catcher behind the plate. To figure this for a catcher, multiply the Earned Runs Allowed by the pitchers while he was catching times nine and divide that by his number of Innings Caught.
Cheap Wins/Tough Losses/Top Game Scores First determine the starting pitcher’s Game Score as follows:
  1. Start with a number of 50
  2. The starting pitcher gets one point for every strikeout he records
  3. After the fourth inning, add 2 points for each additional inning the pitcher goes on to complete. For each strikeout, add one point to your total. For each hit that is permitted, deduct two points. For each earned run that is permitted, subtract 4 points. Add 2 points to account for an unearned run. For each stroll, deduct one point from your total.
If the starting pitcher scores over 50 and loses, it’s a Tough Loss. If he wins with a game score under 50, it’s a Cheap Win.
Cleanup Slugging% The Slugging Percentage of a player when batting fourth in the batting order.
Clutch This category shows a player’s batting average in the late innings of close games: the seventh inning or later with the batting team ahead by one, tied, or has the tying run on base, at bat or on deck.
Complete Game Frequency Complete Games divided by Games Started.
Defensive Batting Average A composite statistic incorporating various defensive statistics to arrive at a number akin to batting average. The formula uses standard deviations to establish a spread from best to worst.
Earned Run Average (Earned Runs times 9) divided by Innings Pitched.
Fast-A Otherwise known as “Advanced A,” these A-level minor leagues are the California League, Carolina League and Florida Stat League.
Favorite Toy The Favorite Toy is a method that is used to estimate a player’s chance of getting to a specific goal in the following example, we’ll say 3,000 hits.Four things are considered:
  1. Needed Hits – the number of hits required to get the desired result. (Of course, this could also be “Need Home Runs” or “Need Doubles” – whatever you choose to call it.)
  2. Years Remaining in the Contract. The formula 24-.6 is used to estimate the number of years that will be required to achieve the target (age). As a result of this approach, players under the age of 20 have 12.0 seasons left on their contract. Players under the age of 25 have nine seasons left on their contract, players under 30 have 6.0 seasons left on their contract, and players over 35 have just three season left on their contract. Any athlete who is currently actively participating in competitive sports is presumed to have at least 1.5 seasons left, regardless of his or her age. Hit Level has been established. For 1996, the established hit level would be calculated by multiplying 1993 hits by two times 1994 hits by three times 1995 hits by six, and then dividing the result by six. A player, on the other hand, cannot have an established performance level that is less than three-fourths of his most recent performance level
  3. For example, a player who had 200 hits in 1995 cannot have an established hit level that is less than 150
  4. Hits that are expected to be made in the future. This is calculated by multiplying the second number (the number of ears left) by the third number (the established hit level)

Once you have obtained the projected remaining hits, the probability of achieving the objective is calculated as (projected remaining hits) divided by (require hits), minus.5. If your “require hits” and your “projected remaining hits” are the same, you have a 50 percent probability of achieving your target using this technique of calculation. If your anticipated remaining hits are 20 percent greater than your required hits, you have a 70 percent probability of achieving your target in time. There are two specific rules, as well as a note:

  1. The probability of a player continuing to develop toward a goal cannot be more than.97 per year. For example, a player cannot calculate that they have a 148 percent probability of completing their goal because this is against the rules.)
  2. The possibility of a player continuing to develop toward the objective cannot be more than.75 each season if his offensive winning percentage is below.500 throughout the season. If a below-average batter is two years away from attaining a goal, his likelihood of accomplishing that objective cannot be proved to be better than nine-sixteenths of a percent, or three-fourths times three-fourths, no of his age.
  3. Rather of using actual figures from a complete season of play, we utilized predicted metrics for 1994 and 1995.
Fielding Percentage (Putouts plus Assists) divided by (Putouts plus Assists plus Errors).
First Batter Efficiency This statistic tells you the batting average allowed by a relief pitcher to the first batter he faces.
GDP per GDP Situation A GDP situation exists any time there is a man on first with less than two outs. This statistic measures how often a player grounds into a double play in that situation.
Go-Ahead RBI Any time a player drives in a run which gives his team the lead, he is credited with a go-ahead RBI.
Ground/Fly Ratio (Grd/Fly) Simply a hitter’s ground balls divided by his fly balls. All batted balls except line drives and bunts are included.
Hold A Hold is credited any time a relief pitcher enters a game in a Save Situation (see definition below), records at least one out, and leaves the game never having relinquished the lead.Note: a pitcher cannot finish the game and receive credit for a Hold, nor can he earn a hold and a save.
Inherited Runner Any runner(s) on base when a relief pitcher enters a game are considered “inherited” by that pitcher.
Isolated Power Slugging Percentage minus Batting Average.
K/BB Ratio Strikeouts divided by Walks.
LateClose A LateClose situation meets the following requirements:
  1. During the seventh inning or later, the batting side is either up by one run, tied, or has a possible tying run on base, at the plate, or on deck
  2. The game is over
Note: this situation is very similar to the characteristics of a Save Situation.
Leadoff On Base% The On-Base Percentage of a player when batting first in the batting order.
No Decision (ND) The result when a starter is credited with neither a win nor a loss.
OBP+SLUG (OPS) On-base percentage plus slugging percentage.
Offensive Winning Percentage (OWP) The Winning Percentage a team of nine Fred McGriffs (or anybody) would compile against average pitching and defense. The formula: (Runs Created per 27 outs) divided by the League average of runs scored per game. Square the result and divide it by (1+itself).
On Base Percentage (Hits plus Walks plus Hit by Pitcher) divided by (At Bats plus Walks plus Hit by Pitcher plus Sacrifice Flies).
Opponent Batting Average Hits Allowed divided by (Batters Faced minus Walks minus Hit Batsmen minus Sacrifice Hits minus Sacrifice Flies minus Catcher’s Interference).
Outfielder Hold Percentage A statistic used to evaluate outfielders’ throwing arms. “Hold Percentage” is computed by dividing extra bases taken (by baserunners) by the number of opportunities. For example, if a single is lined to center field with men on first and second, and one man scores while the other stops at second, that is one extra base taken on two opportunities, a 50.0 hold percentage.
PA* The divisor for On Base Percentage: At Bats plus Walks plus Hit By Pitcher plus Sacrifice Flies; or Plate Appearances minus Sacrifice Hits and Times Reached Base on Defensive Interference.
PCS (Pitchers’ Caught Stealing) The number of runners officially counted as Caught Stealing where the initiator of the fielding play was the pitcher, not the catcher. Note: such plays are often referred to as pickoffs, but appear in official records as Caught Stealings. The most common pitcher caught stealing scenario is a 1-3-6 fielding play, where the runner is officially charged a Caught Stealing because he broke for second base. Pickoff (fielding play 1-3 being the most common) is not an official statistic.
Percentage of Pitches Taken This tells you how often a player lets a pitch go by without swinging.
Percentage of Swings Put In Play This tells you how often a player hits the ball into fair territory, or is retired on a foul-ball out, when he swings.
Pickoffs (Pk) The number of times a runner was picked off base by a pitcher.
Pivot Percentage The number of double plays turned by a second baseman as the pivot man, divided by the number of opportunities.
PkOf Throw/Runner The number of pickoff throws made by a pitcher divided by the number of runners on first base.
Plate Appearances At Bats plus Total Walks plus Hit By Pitcher plus Sacrifice Hits plus Sacrifice Flies plus Times Reached on Defensive Interference.
Power/Speed Number A way to look at power and speed in one number. A player must score high in both areas to earn a high Power/Speed Number.The formula: (HR x SB x 2) divided by (HR + SB).
Quality Start Any start in which a pitcher works six or more innings while allowing three or fewer earned runs.
Quick Hooks and Slow Hooks A Quick Hook is the removal of a pitcher who has pitched less than 6 innings and given up 3 runs or less. A Slow Hook occurs when a pitcher pitches more than 9 innings, or allows 7 or more runs, or whose combined innings pitched and runs allowed totals 13 or more.
Range Factor The number of Chances (Putouts plus Assists) times nine divided by the number of Defensive Innings Played. The average for a Regular Player at each position in 1997:
  • 5.00 points for second base, 2.67 points for third base, 4.56 points for shortstop, and 1.99 points for left field, 2.55 points for center field, and 2.06 points for right field.
Relief Points (Pts) Wins plus saves minus losses
Run Support Per 9 IP The number of runs scored by a pitcher’s team while he was still in the game times nine divided by his Innings Pitched.
Runs Created A way to combine a batter’s total offensive contributions into one number. The formula:(H + BB + HBP – CS – GIDP) times (Total Bases +.26(TBB – IBB + HBP) +.52(SH + SF + SB)) divided by (AB + TBB + HBP + SH + SF).
Runs/Times on Base This is calculated by dividing Runs Scored by Times on Base
Save Percentage Saves (SV) divided by Save Opportunities (OP).
Save Situation A Relief Pitcher is in a Save Situation when upon entering the game with his club leading, he has the opportunity to be the finishing pitcher (and is not the winning pitcher of record at the time), and meets any one of the three following conditions:
  1. He enters the game with a lead of no more than three runs and has the opportunity to pitch for at least one inning, or he enters the game with the potential tying run on base, at bat, or on deck, regardless of the count, or he pitches three or more innings regardless of the lead and the official scorer awards him a save
  2. Or he pitches three or more innings regardless of the lead and the official scorer awards him a save
SBA Stolen-base attempts against a catcher
SB Success% Stolen Bases divided by (Stolen Bases plus Caught Stealing).
Secondary Average A way to look at a player’s extra bases gained, independent of Batting Average. The formula:(Total Bases – Hits + TBB + SB) divided by At Bats.
Slow-A Otherwise known as “Regular A,” these full-season minor leagues contain less-experienced professional players. The Slow-A leagues are the Midwest League and South Atlantic League (Sally).
Slugging Percentage Total Bases divided by At Bats.
Stolen Base Percentage Allowed This figure indicates how successful opposing baserunners are when attempting a stolen base. It’s stolen bases divided by stolen-base attempts.
Times on Base Hits plus walks plus hit by pitch
Total Bases Hits plus Doubles plus (2 times Triples) plus (3 times Home runs).
Win-Loss Percentage or Winning Percentage Wins divided by (Wins plus Losses).
Zone Rating Simply the percentage of balls fielded by a player in his typical defensive “zone,” as measured by STATS reporters.

Breakdown Categories
Ahead/Behind in Count For hitters, ahead in count includes 1-0, 2-0, 3-0, 2-1 and 3-1. Behind in count for hitters includes 0-1, 0-2, 1-2 and 2-2. The opposite is true for pitchers.
Day/Night Officially, night games in the National League are those that start after 5:00 pm, while night games in the AL begin after 6:00 pm. Therefore, a game at 5:30 in Yankee Stadium is a day game while one in Shea Stadium at the same time is a night game. We avoid this silliness by calling all games starting after 5:00pm night games.
First Pitch Refers to the first pitch of a given at bat, and any walks listed here are intentional walks.
Grass/Turf Grass is grass. Turf is artificial turf.
Groundball/Flyball Ratio A hitter’s stats against pitchers that induce mostly grounders or flies, respectively. If the ratio is less than 1.00, then he is a Flyball hitter. If it is greater than 1.50, he is a Groundball hitter. Anything else is classified as neutral. Same cutoffs apply for classifying pitchers. Anyone with less than 50 plate appearances is automatically neutral.
First Inning Pitched Describes the result of the pitcher’s work until he recorded three outs.
Inning 1-6 and Inning 7+ These refer to the actual innings in which a pitcher worked.
None On/Out Refers to situation when there are no outs and the bases are empty (generally leadoff situations).
None On/Runners On Describes the status of the baserunners
Number of Pitches This section shows the results of balls put into play while his pitch count was in that range.
Pitcher/Batter Match-Ups The following conditions must be met before a player is added to the list:
  • For a batter to be considered a “Hits Best Against” candidate, there must be at least 10 plate appearances between him and the pitcher
  • And for a pitcher to be considered a “Pitches Best Against” candidate, the batter must have a.300 batting average against the pitcher, and the pitcher must limit the batting average of the batter to under.250.
Thus, not all hitters will have five pitchers that qualify and not all pitchers will have five batters who qualify.
Scoring Position At least one runner must be at either second or third base.
Vs. 1st Batr (Relief) Describes what happened to the first batter a reliever faces.

Double-A (baseball) – Wikipedia

Since 1946, Double-A (formally Class AA) has been the second-highest level of competition in Minor League Baseball in the United States, after only Triple-A. There are currently 30 teams classified at the Double-A level, one for each team in Major League Baseball, organized into three leagues: Double-A Central, Double-A Northeast, and Double-A South. The Double-A level is divided into three divisions: Double-A Central, Double-A Northeast, and Double-A South. During the minor league restructuring in 2021, the three existing Double-A leagues will take over for the Texas League, Eastern League, and Southern leagues, which were all eliminated at the time.

History

Class AA (sometimes known as “Double-A”) baseball was established in 1912 as the new highest level in Minor League Baseball, replacing Class A. Prior to the founding of the National Association of Professional Baseball Leagues (the formal name of Minor League Baseball) in 1901, Class A was the highest level of competition.: 15 Three leagues were recognized as Class AA prior to the start of the 1912 season: 236

  • The American Association (AA), the International League (IL), and the Pacific Coast League (PCL) are the four major leagues in the United States.

Prior to joining Class A, each of these leagues had been in Class B. The majority of them remained in Class AA until 1945,: 396 of them then advanced into Class AAA (” Triple-A “) when it was formed in 1946.: 15 A class A1 level (in the middle of Class A and Class AA) was formed in 1936 and was used until 1945. During that time period, no additional leagues were recognized as Class AA. A new classification system for Minor League Baseball was introduced in 1946, with the current Double-A classification serving as the second-highest level in the organization.

  • The Southern Association, formerly Class A1 (1936–1945)
  • The Texas League, formerly Class A1 (1936–42
  • Idle for three seasons during World War II)
  • And the Western League are all former Class A1 leagues.

For the following 75 years, the Texas League would stay on the Double-A level. It was during this time period that only minor adjustments were made to the Double-A level leagues, including:

  • 732
  • 1961: the final season of the Southern Association: 743
  • 1963: the Eastern League and original South Atlantic League were moved from Class A to Double-A: 731, 743
  • 1964: the original South Atlantic League was reconstituted as the Southern League: 733
  • 1967: the Mexican League was promoted to Triple-A: 732
  • 1968-69: the Mexican League was promoted to Triple-A: 732
  • 1969-70: the Mexican League was promoted to Triple-A: 732
  • 1970-71

The Texas League had been at Double-A since 1946, the Eastern League since 1963, and the Southern League since 1964 when the COVID-19 pandemic forced the cancellation of the 2020 minor league season (which was not played because of the pandemic).

Prior to the 2021 season, Major League Baseball (MLB) restructured the minor leagues, resulting in the elimination of all three Double-A leagues, which were subsequently replaced by the Double-A Central, Double-A Northeast, and Double-A South divisions, respectively.

System

In most cases, players in the Double-A classification are still in their developmental stages and have just a few years of experience in professional baseball. Those who reach the Double-A level do so by promotion from one of the lower-level leagues, with Class A-Advanced (sometimes known as “High-A”) being the league directly below Double-A in the minor league structure. A player’s promotion to Double-A might be one of the most difficult in his or her career since it is the level at which pitchers are required to have a decent off-speed pitch in their arsenal.

  • In order to begin their minor league careers, certain players may be assigned to Double-A.
  • In addition, big league organizations may assign players to their Double-A affiliate in order to recuperate from their injuries.
  • For example, over the period 1978–2018, the Toronto Blue Jays organization promoted 17 position players from Double-A to the Major League Baseball (MLB) at a rate of about one player every two seasons.
  • Because players are not going back and forth from the major leagues at this level, as is sometimes the case at Triple-A, the rosters tend to be more stable at the higher level.

Playoffs

All three existing Double-A leagues played split seasons prior to the minor leagues’ restructuring in 2021, with the Eastern League becoming the first to do so in 2019. The minor leagues’ reform is scheduled to take place in 2021. In the postseason, the teams who finished first or second in their division in either half of the season qualified, with wild card teams filling out the remaining slots in a bracket tournament that was typically comprised of four teams. Small-league baseball announced on June 30, 2021, that the top two teams in each league (determined by winning percentage over the course of the whole season, regardless of division) will play in a best-of-five postseason series to determine the league champion.

All-Star Games

Prior to the restructuring of the minor leagues in 2021, each of the active Double-A leagues conducted its own midseason All-Star Game. This practice continued until the 2021 reorganization of the minor leagues. From 1991 through 2002, the three organizations collaborated to host theDouble-A All-Star Game, which pitted teams of American League -affiliated All-Stars against teams of National League -affiliated All-Stars in a single game.

Teams schedules were announced without a break for an all-star game after the start of the 2021 minor league season was postponed by a month due to weather conditions.

Awards

Pitch clocks with a 20-second delay were introduced in Double-A ballparks in 2015 as part of the pace-of-play enhancements launched in 2015. When there are no runners on base, the duration has been reduced to 15 seconds as of 2018. The addition of extra innings with a runner on second base and the restriction of teams to eight mound visits during a nine-inning game were two other notable alterations enacted in 2018 as well. From 2019 onward, the number of mound visits was decreased to seven, and pitchers were obliged to face a minimum of three consecutive hitters, unless the side was dismissed or the pitcher was hurt and unable to go.
