What's an even number in baseball

MLB Glossary: ​​Baseball Explained - Homeruns, Strikeouts, Hits, Perfect Games, Statistics


Major Leagues: The AL and NL form the Major Leagues. The leagues below are summarized as minor leagues.

Manager: The manager is, so to speak, the head coach and sets lineups, batting orders and pitching rotation and decides on substitutions and tactics during the game. The special thing about baseball is that the managers, like their coaches, all wear the same uniforms that the players wear on the field. In addition, everyone gets their own shirt number.

Mendoza Line: This broad term goes back to shortstop Mario Mendoza, whose performance was generally rated as historically poor. He finished his best season with a batting average of .215, the Mendoza Line is therefore a batting average of .200. If you hit under it, you are particularly bad.

Minor Leagues: In a way, the foundation of the MLB. The minor leagues include various divisions such as Single-A, Double-A and Triple-A. The teams are all partners of the MLB teams and the majority of the players are under contract with the MLB team, with others these teams at least hold the rights to the players. Young talents in particular usually have to play their way through numerous of these levels in order to make it into the Big Leagues.

Mound: The mound is the hill in the middle of the infield on which the pitcher stands and pitches.

MVP: As in the other US sports leagues, an MVP is also chosen in the MLB at the end of the season, but in both leagues. He is elected by selected journalists from the Baseball Writers Association of America. This can also be a pitcher, although they will be awarded the Cy Young again separately.

MLB: All MVPs of the new millennium


National League: The counterpart to the AL is the NL. This has been around since 1876, almost 30 years longer than the AL. It also consists of three divisions of five teams (East, Central, West). It continues to adhere to the basic principle that the pitcher must step on the plate.

No decision: If a pitcher is neither involved in winning nor losing, he receives a no-decision. This does not change his balance sheet. For example, if a starting pitcher with a late lead goes out of the game, which is then given away from his bullpen, he gets a no-decision.

No-hitter: One of a pitcher's greatest accomplishments is being a no-hitter. That is, a pitcher doesn't hit a single hit in an entire game. If he manages this over an entire game, the no-hitter is assigned to him alone. However, there have already been combined no-hitters in which starting pitcher and reliever did not allow a hit together. In a no-hitter you can allow runs and lose them. By the way, the record holder for no-hitters is Nolan Ryan, who has won seven of them in his career. See also "Perfect Game".


OBP: The on-base percentage indicates how often a batter reaches at least first base per plate appearance (by hit, walk or hit-by-pitch), i.e. comes to base. It is generally said that with good hitters this value is at least 100 percentage points above the average. Example: With 2 hits out of 10 at-bats you would get an average of .200. But if the hitter also managed 2 walks, his OBP would be .333 (4/12). Many therefore see the OBP as more meaningful than the average.

On-Deck Circle: The area at the exit of the dugout, where the next batter prepares and waits for his appearance at the strike.

Out: The goal of a defense is basically to get three outs in one inning, i.e. to identify the offensive players. This can be done in a number of ways. If you catch a ball that has been hit in the air before it hits the ground or a wall, the batsman is out. He is just as out when he hits a ball on the ground and the defense throws the ball in front of the batter at first base. An offensive player can also be identified by force out or by "tag", i.e. touching him with the ball (in a glove) while the offensive player has no contact with a base.

Outfield: The area of ​​the playing field that is outside the infield.

Outfielder: The defenders in the outfield. These are the Right Fielder, Center Fielder, and Left Fielder.


Passed ball: If a catcher lets a pitch slip through which he could easily have caught and thereby a base runner can advance at least one base, this is a passed ball. If the pitcher makes a mistake, it is called a "wild pitch".

Perfect Game: The perfect game. A starting pitcher creates 27 outs in a row without allowing a single base runner in the entire game and without an error on his defense. In the history of the MLB, this has only happened 23 times, most recently Felix Hernandez in 2012 (as of March 2017). While walks, hit-by-pitches or errors can also occur in a no-hitter, in a perfect game everything literally has to go perfectly.

Pick-Off: If there are runners on base, they can be identified without the batter's involvement. To do this, the pitcher throws to the appropriate base. If the defender then manages to touch the runner before he makes contact with the base, he is out. For this purpose, some pitchers have special moves that look like pitches, but then become base throws. In many cases, however, such pick-off moves are always located on the border with the Balkans and are therefore not entirely without risk. In addition, there is of course the possibility that the baseman does not catch the ball and it rolls away.

Pinch-Hitter: The substitute batsman. You switch him on to replace a player in the batting order. The substituted player is then allowed to take the position of the substituted player - or is exchanged again. For example, if they are behind, strong offensive players are substituted on again.

Pinch runner: The substitute runner. If you want to increase your chances of a run, you can replace a runner who is already on base with a usually faster player who then runs for that person. The substitute then takes over the position of the substituted player or is substituted himself.

Pitch: A pitcher's throw to catcher. A pitch basically opens every move and has to be carried out in a technically clean manner. Nowadays, a starting pitcher is usually exchanged after around 100 pitches - earlier if the performance is poor.

Pitch-out: A pitch-out is a pitch that is intentionally thrown high and far outwards - in coordination with the catcher who jumps up to catch the ball. This is done in anticipation of a base runner's steal attempt. Standing, it is easier for the catcher to then throw the ball to second or third base in order to catch the base stealer. in the at-bat this is of course a ball.

Pitcher Statistics: In match reports, the pitcher's statistics are often given in abbreviated form. Particular attention is paid to the number of innings, hits, earned runs and strikeouts. A statline of (6.2 IP, 5 H, 4 ER, 8 K) would mean, for example, that a pitcher has completed six complete innings and had two outs in the seventh inning. He allowed 5 hits and a total of 4 earned runs and recorded 8 strikeouts. The walks and home runs are also often given in detailed box scores.

Pitching Coach: The pitching coach is the one who exclusively looks after the pitchers. During the game, he is usually the first instance when it comes to going on the mound and talking to his current pitcher, especially if he is not in the best shape or if the situation requires special discussion.

Pitching rotation: Starting pitchers are rotated according to a clear pattern. Usually these rotations consist of five pitchers who always start one after the other. A starting pitcher usually has four days off between his bets, and five days off when there are no games. In the playoffs, the Ace is sometimes allowed to play with only three or even fewer days off - he then pitches "on short rest".

Plate appearance: Basically, as a batter, all you have to do to collect a plate appearance is take the shot. The plate appearance is then taken into account regardless of the result.

Platoon: When two players share the stakes in one position based on their striking strength against left and right handed pitchers, this is called a platoon. In general, right-handed batter is usually a bit stronger against right-handed people, but a bit weaker against left-handed people (and vice versa).

Popup: A fly ball that is hit very high and usually does not leave the infield. Such a fly ball is usually easy to catch.

Prospect: Promising talents are referred to as prospects in the MLB. These are both future high performers for your own team and potential trade candidates for other teams.


Quality Start: A statistic for a starting pitcher. In order to achieve a quality start, the pitcher must complete at least six innings and must not submit more than three earned runs.


RBI: Runs Batted In - The stats for the batsman to count how many runs he is responsible for due to his batting performance. How many runs does he make? If he hits a solo homerun, he gets an RBI, for a two-run homer there are two, etc. - but this also means: the more players are on base while the batsman's turn, the greater his chance of one or several RBI. In addition, you get an RBI if you are identified yourself while a run is being scored. But not if you hit a double play.

Relief Pitcher: The substitute pitcher. Pitcher can generally be changed once per at-bat / plate appearance. Some are designed to pitch multiple innings, others are specialists in a few outs. See also "Closer" and "Setup Man".

Rookie: As usual in US sport, newcomers to MLB are called rookies. However, the newcomer is not limited to the first season, but describes a fixed status: After 130 at-bats or 50 innings as a pitcher, the rookie status expires. However, players from international leagues are just as much rookies as young talents from the Minors.

Rotation: See pitching rotation.

Rubber: The rubber is the small plate on the mound that the pitcher must have contact with before and during his pitch.

Run: A run is a point in baseball. It is achieved by crossing home plate before being identified along the way.

Runner: Also "Base Runner". As soon as a batter comes to base he is a base runner.
