- Cutter (baseball)
In baseball, a cutter, or cut fastball, is a type of fastball which breaks slightly toward the pitcher's glove side as it reaches home plate. This pitch is somewhere between a slider and a fastball, as it is usually thrown faster than a slider but with more motion than a typical fastball. Some pitchers use a cutter as a way to prevent hitters from expecting their regular fastballs. A common technique used to throw a cutter is to use a four-seam fastball grip with the baseball set slightly off center in the hand. When a batter is able to hit a cutter pitch, it often results in a ground ball leading to an easy out.
When the cut fastball is working correctly, mainly against opposite-handed batters (e.g., a right-handed pitcher facing a left-handed hitter), the pitch can crack and split a hitter's bat, hence the pitch's occasional nickname of "the buzzsaw." Ryan Klesko, then of the Atlanta Braves, broke three bats in a single plate appearance during the 1999 World Series while facing Mariano Rivera. A few switch hitters have even been known to bat right-handed against the right-handed Rivera (the "wrong" side; switch hitters generally bat from the side of home plate opposite to the pitcher's throwing hand).
Braves third baseman Chipper Jones attributed the increased dominance of pitchers from 2010-2011 to a more prolific use of the pitch, as did Cleveland Indians pitcher Chris Perez.  In 2010, Roy Halladay threw a cutter 34.2% of the time, the highest rate among major league starters.
