A relief pitcher who is as "tough as nails" or very effective at nailing down a win is sometimes said to be "nails". "As the season has progressed, you can see that he looks forward to that 9th inning and he has been nails lately." "This guy has been nails for us," Cardinals manager Tony La Russa said. Phillies and Mets center fielder Lenny Dykstra was known as "Nails" for his all-out style of play.
An informal rule that used to apply to double plays. As long as the defensive player covering second base was in the "neighborhood" of second base when he caught the ball and threw it on to first base, the runner would be called out. The rule was designed to compensate for runners who slid into second too hard, making it dangerous for the defensive player. In recent years, umpires have required the defensive player to have a foot actually on second base, not just in the neighborhood, and have penalized runners who slide toward the defensive players too aggressively, so neighborhood plays are rarely seen today.
The official name of either of the two on-deck circles. Each team has its own circular area, five feet (1.5 m) in diameter, which is designated for unencumbered use by the on-deck batter (the next batter due to bat after the current batter); the on-deck batter may wish to stretch, run in place, or take practice swings immediately prior to taking his turn in the batter's box (which actually is rectangular in shape). Especially during finals and semifinals, each circle is typically painted with the corresponding team logo. The location of the next batter's box is specifically defined in MLB rules, and the most common method to locate it was granted a patent.
When a pitcher focuses on pitching just at the left or right edges of home plate rather than throwing a pitch over the heart of the plate where a batter can get the meat of the bat on the ball, he's said to nibble at the edges. Tigers manager Jim Leyland praised Scherzer for his aggressiveness against such a powerful lineup: "The one thing you can't do against the Yankees is get behind in the count. If you do, they'll just sit on pitches and hit a lot of them hard. Max went after them. He understood he couldn't nibble around the edges of the plate, and he did a heckuva job."
A slider. Also used to mean an average or possibly "hanging" slider. Hitters look at the spin on a ball when it is released by the pitcher, so the "dot" (circle which is created from the pitcher's rotation on the ball that the batter sees to identify a pitch as a slider out of the pitcher's hand) is said to be "nickel sized". Also, it could be used to mean a pitch with more lateral movement (closer to a slurve than to a slider) rather than velocity.
Abbreviation for National League Division Series: the first round of the league playoffs, to determine which two teams advance to the National League Championship Series (NLCS). This round pits the winners of each of the three league divisions plus the winner of the wild-card slot (the team that wins the most games in the regular season without winning a division) in two pairings, each of which plays a best three out of five series to determine who advances to the NLCS.
Any starting pitcher who earns neither a win (W) nor a loss (L) is said to have a "no decision", which has no special meaning in official baseball statistics; however, it has become conventional to note whether he made a quality start.
A home run whose landing destination in the stands is in no doubt from the moment it leaves the barrel of the bat. A no-doubter will be seen/heard to "leap" off the bat, usually having a launch angle between 20 and 40 degrees and high exit velocity.
A game in which one team does not get any hits, a rare feat for a pitcher, especially at the major league level. Also colloquially called a "no-no". If no batter reaches base safely by any means (walk, error, etc.) the pitcher is said to have pitched a perfect game, which is much rarer than a "normal" no-hitter.
It is a superstition that when a pitcher is working on a no-hitter (or perfect game), his teammates stay far away from him (sometimes even a whole bench length) and will not say anything to anyone about the no-hitter. Some play-by-play on-air announcers will also avoid mentioning the no-hitter until either an opposing batter gets a hit or the no-hitter is completed; others however will mention one in progress and are sometimes blamed for jinxing no-hitters.
The portion of a ballpark's spectator area, usually the front row of seats, where a fielder may legally reach into to catch a fly ball, while a spectator or other personnel may legally touch same fly ball even if it interferes with the fielder's attempt to catch it. A ball touched by a spectator in this manner is not spectator interference.
Sometimes said by a play-by-play announcer when the bases are loaded, i.e., there is no open base. Usually means that intentionally walking and pitching around the batter are poor strategies for the fielding team, as a walk will score a run for the batting team. Also "no place/nowhere to put [the batter]".
A Non-Roster Invitee (NRI) is a player invited to Spring training who is not yet on a Major League team's 40-man roster. He may be a young prospect, a veteran who has been released from or retired from a previous contract with a team, perhaps someone who left baseball after an injury. If he performs well, he has a chance to be placed on the roster and assigned to a minor league team or even join the major league team.
