In the world of Major League Baseball (MLB), few pitches are as revered and feared as the cutter. This pitch, characterized by its late break and ability to induce weak contact, has been a significant factor in the success of relief pitchers. Among them, Kenley Jansen has emerged as a master of this art, turning the cutter into his signature weapon. In this article, we will delve into the mechanics of Jansen’s cutter, its impact on his career, and how it has shaped the landscape of modern pitching.
The Evolution of the Cutter
The cutter, short for “cut fastball,” is a pitch that blends the characteristics of a fastball and a slider. It typically breaks slightly towards the pitcher’s glove side as it approaches the batter. The cutter gained prominence in the late 20th century, largely popularized by pitchers like Mariano Rivera, who turned it into a legendary weapon. Kenley Jansen, a former catcher turned pitcher, has taken this pitch to new heights.
Kenley Jansen’s Journey to Mastery
Kenley Jansen was born on September 30, 1987, in Curacao. His journey to MLB stardom began when he was signed by the Los Angeles Dodgers as an amateur free agent in 2004. Initially, Jansen played as a catcher but transitioned to pitching after the Dodgers recognized his arm strength and potential on the mound.
It wasn’t until 2011 that Jansen started developing his cutter into a dominant pitch. By honing his mechanics and understanding how to manipulate the ball’s movement, he transformed himself from a promising prospect into one of the league’s elite closers.

- Arm Angle: His arm angle is crucial; Jansen utilizes a high three-quarters arm slot, which adds deception and helps create the late break that is characteristic of an effective cutter.
- Release Point: A consistent release point helps Jansen maintain control and accuracy, allowing him to command the pitch effectively.
- Follow Through: After release, Jansen’s follow-through is smooth and controlled, which minimizes injury risk and maximizes velocity.
