When Mariano Rivera entered the game, chances are New York Yankees fans felt good about their chances of winning. After all, Rivera’s cut fastball was one of the best in the game, and hitters had a hard time squaring the pitch up to make solid contact. With a career Baseball WHIP of 1.00, Rivera’s cutter grip made him enter the Hall of Fame, along with All-Star appearances, 5 World Series Championships, and MVP awards. So what exactly is a cutter pitch, what does it do, and just how good was Rivera throwing that pitch? Find out these questions and more below!
What is a Cutter / What Does it Do?
A cutter or cut fastball is a baseball pitch that deviates towards the pitchers’ glove hand when they release the ball. For example, a right-handed pitcher throwing the cutter will have the ball break inside to left-hand hitters. Similarly, throwing a cutter to a right-hand hitter will break away from them, which looks like a strike to the batter until the last second. The effectiveness of a cut fastball is the late break or deviation that the ball takes as it arrives at home plate. When batters are unable to square up the ball with the barrel of the bate, they may miss and or break their wooden bat when making contact with the ball.
How to Grip / Throw a Cutter Pitch?
The cutter grip that big league pitchers use is having their index and middle finger close together over baseball’s seams. Next, the ring finger will rest on the baseball seam while the thumb is underneath the index finger and middle finger. Finally, throwing the pitch requires a consistent delivery with the pitcher’s arm, which helps deceive hitters since the late movement could look like a traditional four-seam fastball that might end up in the strike zone or slightly end up a bit outside.
How Similar is the Pitch to Other Pitches?
A cutter is a mix between a fastball and a slider. The cut pitch is similar in the break to a slider, but the angle is more level upon release, unlike a slider. For example, a slider will be slower than a cutter but will drop more in angle. Whereas a fastball is similar in speed to a cutter, the cutter break goes towards the pitcher’s glove side, unlike a fastball staying straight. If a pitcher throws a two-seam fastball, the break will go towards the pitcher’s throwing arm, which is opposite of the cutter.
The Best Cutter Pitchers in Baseball History

Why Did Rivera Break So Many Bats with the Cutter?
The cutter makes the ball move inside to the opposite side of the throwing arm of the pitcher. For example, Rivera was a righty, so his cut fastball would move into lefty hitters as it arrived at home plate. Unlike a traditional four-seamer that would stay straight to hitters, the cutter would have late movement as it goes to home plate. With the late movement (like a breaking ball), batters would be unable to square the bat to the ball and make contact closer to where their hands were holding the bat. When you make contact with the ball in that type of spot on the bat, you generally will break it since it’s the weakest part of the bat.
Conclusion on the Cutter Pitch
In conclusion, a cutter pitch can effectively get Major League hitters out for starting pitchers and relievers. Just like a changeup, curveball, slurve pitch, fastball, sinker, splitter, and even knuckleball, changing speeds and where the ball moves are all ways to throw of a hitter’s timing. What comes down to it is if the pitcher has the right feel for the pitch and can record outs when throwing that pitch to hitters.
