Appendix:Glossary of baseball jargon (M)

make-up call

 * When an umpire makes a bad call on a pitch, he may implicitly acknowledge it on a later pitch by making another bad call to "make up" for the first. For example, say an umpire mistakenly calls a strike on a pitch that is out of the strike zone; he may later call a ball on a pitch that's in the strike zone so that the hitter gets back what was initially taken away. Umpires typically, and understandably, deny that there is any such thing as a "make-up call".

make-up game

 * When a game is cancelled because of a rainout or for some other reason, a make-up game is usually scheduled later in the season. Late in the regular season if the outcome of that game would not affect which teams would reach the play-offs, then the game might not be made up.

manager

 * See field manager. Different from the general manager.

manufacturing runs

 * Producing runs one at a time, piece by piece, component by component by means of patience at the plate, contact hitting, advancing runners, taking advantage of errors, alert baserunning including stealing a base or advancing on an out or a mistake by a fielder. In other words: small ball.

masher

 * A home-run hitter. See crush the ball.

matchsticks

 * A string of 1's on the scoreboard (the shape of matchsticks), indicating successive innings in which 1 run was scored.

meat

 * A rookie, popularized by the baseball movie, Bull Durham; implying more brawn than brain.
 * An easy out, typically evident during a strikeout.
 * A baserunner easily thrown out at a base.
 * A fielder's throwing hand, typically used for the pitcher; “Glavine started to reach for the ball with his meat hand but then thought better of it.”

meatball

 * An easy pitch to hit — down the middle of the plate.

Mendoza line

 * A batting average of .200. Named (most likely) for Mario Mendoza, a notoriously poor hitter of the 1970s who still managed to have an 8-year career.

men in blue

 * The umpires.

middle infielders

 * The second baseman and shortstop.

middle innings

 * The fourth, fifth and sixth innings of a regulation nine-inning game.

middle of the inning

 * The time between the top half and bottom half of an inning when the visiting team takes the field and the home team prepares to bat. No gameplay occurs during this period and television and radio broadcasts typically run advertisements. See also seventh-inning stretch.

miscue

 * An error. A word from billiards, when the cue stick slips or just brushes the cue ball thereby leading to a missed shot.

mistake

 * A "mistake" is poor execution, as distinguished from an error. It could be throwing to the wrong base, missing the cut-off, running into an obvious out, or throwing a pitch into the batter's "hot zone" instead of where the catcher set up for it.


 * Perhaps one of the most over-used excuses in baseball. Sometimes the pitcher may try to absolve himself for his mistakes, but his manager might have a different opinion. After giving up two home runs to Phillies slugger Ryan Howard, and losing the game 3-2 as a result, Marlins pitcher Scott Olsen remarked:  "Except for a couple of pitches to Ryan, I pitched a good game. He's got 56 home runs for a reason."  Marlins manager Joe Girardi had a different view: "We've talked about not letting him beat us," Girardi said. "Ollie made some mistakes to one guy. He's one guy in the league right now you can't afford to make mistakes to. All I'm going to say is we didn't execute the way we were supposed to."


 * There may be such a thing as a mistake hitter, a mediocre hitter who occasionally gets a pitch that he can drive. But a "mistake pitcher" doesn't usually last long in the big leagues.


 * When asked how the mighty Yankees lost the 1960 World Series, Yogi Berra remarked, "We made too many wrong mistakes."

mistake hitter

 * A batter who isn't adept at hitting good pitches that are located well but can take advantage of a pitcher's mistakes.

mitt

 * "Mitt" (derived from "mitten") can refer to any type of baseball glove, though the term is officially reserved to describe the catcher's mitt and the first-baseman's mitt. Those mitts (like a mitten) have a slot for the thumb and a single sheath covering all the fingers, rather than the individual finger slots that gloves have. By rule, mitts are allowed to be worn only by the catcher and the first baseman. See the entry on glove.

MLB

 * Major League Baseball: the organization that operates the two North American major professional baseball leagues, the American League and the National League. This organization also seeks to control the rights to all commercial products based on Major League Baseball team and player achievements, although its claimed right to limit the use of player statistics for fantasy baseball and computer simulation games has been challenged in court.  MLB presents a lot of information (as well as innumerable promotional efforts) in its electronic portal MLB.com, which is managed by MLB's subdidiary MLB Advanced Media.


 * Although minor league baseball is closely linked to (and governed by) major league baseball, the official portal for minor league baseball is found elsewhere on the internet as MiLB.com., which is also operated by MLB Advanced Media.

Moneyball

 * An often misused term. It refers to Michael Lewis's 2002 book. "Moneyball player" most often refers to one who has a high on-base percentage, and does not steal a lot of bases. However, the essence of the book is about running an organization effectively by identifying inefficiencies and finding undervalued assets in a given market. As an example, the so-called Moneyball teams have shifted their focus to defense and speed instead of OBP which is no longer undervalued. "Moneyball" is often seen as the antithesis of "smallball", where teams take chances on the basepaths in an attempt to "manufacture" runs.  In more traditional baseball circles, evoking Moneyball to describe a player or team can be a term of derision.

moonshot

 * A home run hit so high and deep that it is said to travel toward the moon.


 * When the Dodgers first moved out to Los Angeles and played in the L.A. Coliseum, home runs hit by Wally Moon over the short left-field fence (251 feet down the left-field line, a 42-foot high fence) were also headlined in the newspapers as "Moon Shots." Moon didn't hit many home runs in the Coliseum.  That these were opposite-field home-runs, however, brought more attention to them.

mop up

 * A mop-up pitcher is usually the bullpen's least effective reliever who comes in after the outcome of the game is all but certain. Sometimes other position players also come in to mop up in the last inning, and give the regulars a rest.

mound

 * The pitcher's mound is a raised section in the middle of the diamond where the pitcher stands when throwing the pitch. In Major League Baseball, a regulation mound is 18 feet (5.5 m) in diameter, with the center 59 feet (18.0 m) from the rear point of home plate, on the line between home plate and second base. The front edge of the pitcher's plate or rubber is 18 inches (45.7 cm) behind the center of the mound, making it 60 feet 6 inches (18.4 m) from the rear point of home plate. Six inches (15.2 cm) in front of the pitcher's rubber the mound begins to slope downward. The top of the rubber is to be no higher than ten inches (25.4 cm) above home plate. From 1903 through 1968 this height limit was set at 15 inches, but was often slightly higher, especially for teams that emphasized pitching, such as the Los Angeles Dodgers, who were reputed to have the highest mound in the majors.

movement

 * Deviations from the expected flight of a pitch that make the ball harder to hit. Can be used to refer to both fastballs and breaking balls.

mow them down

 * A pitcher who dominates the opposing hitters, allowing few if any to get on base, is said to have "mowed them down" as if they were just so much hay being cut down by a mower.

muff

 * To make an error, typically on an easy play. "He muffed it. The ball went right through his legs."

murderer's row

 * Murderers' Row was the nickname given to the New York Yankees baseball team of the late 1920s, in particular the 1927 team. The term was actually coined in 1918 by a sportwriter to describe the 1918 pre-Babe Ruth Yankee lineup, a team with quality hitters such as Frank "Home Run" Baker and Wally Pipp that led the A.L. in home runs with 45. In subsequent years, any line-up that has a series of power hitters who represent a daunting challenge to opposing pitchers might be dubbed by the press as a "murderer's row."

mustard

 * Refers to a high amount of velocity on a throw or pitch. A player may be exhorted to "put some (extra) mustard on it," with "it" usually referring to a pitcher's fastball or fielder's throw.
