The Chicago White Sox have faced challenges this season, especially in the pitching department, with only pitchers Garrett Crochet and the now-traded Erick Fedde producing more than 1.3 WAR. Despite this, rookie right-hander Jonathan Cannon, a 24-year-old third-round pick from the University of Georgia, has shown promise with a 4.37 ERA, a 4.57 FIP, and 1.2 WAR over 119 2/3 innings. His five-pitch mix and strategic approach to the game highlight his potential.
Prior to the season, Eric Longenhagen rated Cannon with a 45 FV, identifying him as a strong prospect thanks to his repertoire depth and command. Cannon shared insights into his pitching mentality during a recent visit to Fenway Park.
David Laurila: You primarily rely on your sinker, but haven’t seen great success with it this season. Can you explain why?
Jonathan Cannon: “The main issue has been the command of my sinker. Successful sinkerballers like Logan Webb excel at commanding it down-and-away to right-handed batters, setting up other pitches. I’ve struggled with this, often leaving my sinkers elevated around thigh-high, resulting in fewer groundballs. I’ve been working on throwing more changeups to complement my sinker and diversifying my pitch selection to improve results.”
Laurila: What are the metrics on your sinker?
Cannon: “My sinker has around two to four inches of vertical movement and 15 inches of horizontal movement. While the metrics are solid, I’ve realized that the sinker’s location and overutilization have been key factors in its effectiveness.”
Laurila: Why don’t you throw as many sinkers to left-handed batters?
Cannon: “Lefties have been hitting my sinker well, likely over .400. To counter this, I’ve incorporated more four-seamers and cutters to challenge them inside. The sinker up-and-in to lefties can be a challenging pitch, but it’s essential to disrupt their hitting patterns.”
Laurila: Do you foresee adjusting your pitch selection moving forward?
Cannon: “I believe my sinker and sweeper are too valuable to abandon. While I may incorporate more four-seamers occasionally, my sinker and sweeper remain essential parts of my repertoire.”
Laurila: How do you balance using your best pitches with incorporating your entire arsenal?
Cannon: “It’s crucial to remain adaptable. I’ve found success by adjusting my pitch selection based on hitters’ tendencies and scouting reports. Maintaining a mix of pitches keeps hitters off balance and allows me to consistently get outs.”
Laurila: Any final thoughts?
Cannon: “My pitches are performing well analytically. The key is refining how I use them to effectively retire batters. This season has been a valuable learning experience for me.”
