context_page_description: In baseball, a cut fastball or cutter is a type of fastball that breaks toward the pitcher's glove-hand side, as it reaches home plate. This pitch is somewhere between a slider and a four-seam fastball, as it is usually thrown faster than a slider but with more movement than a typical fastball. Some pitchers use a cutter to prevent hitters from expecting their regular fastballs. A common technique for throwing a cutter is to use a four-seam fastball grip with the baseball set slightly off center in the hand. A batter hitting a cutter pitch often achieves only soft contact and an easy out due to the pitch's movement keeping the ball away from the bat's sweet spot. The cutter is typically 2–5 mph slower than a pitcher's four-seam fastball. In 2010, the average pitch classified as a cutter by PITCHf/x thrown by a right-handed pitcher was 88.6 mph; the average two-seamer was 90.97 mph.
context_section_description: The New York Yankees' former closer Mariano Rivera, one of the foremost practitioners of the cutter, made the pitch famous after the mid-1990s, though the pitch itself has been around since at least the 1950s.
  When the cut fastball is pitched skillfully at speed, particularly against the opposite hand batter (that is, 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". Batter Ryan Klesko, then of the Atlanta Braves, broke three bats in a single plate appearance during the 1999 World Series while facing Rivera. To deal with this problem a few switch hitters batted right-handed against the right-handed Rivera—that is, on the "wrong" side, as switch hitters generally bat from the same side of the plate as the pitcher's glove hand.
  In 2011, Dan Haren led all major league starting pitchers with nearly 48% of his pitches classified by PITCHf/x as cutters. Roy Halladay was close behind at 45%. Other pitchers who rely (or relied) heavily on a cut fastball include Jon Lester, James Shields, Josh Tomlin, Will Harris, Mark Melancon, Jaime Garcia, Kenley Jansen, Wade Miley, David Robertson, Jerry Reuss, and Andy Pettitte.
