As the 2024 season approaches, Arizona Diamondbacks pitcher Slade Cecconi is filled with anticipation. Selected as the 33rd overall pick in the 2020 MLB Draft, Cecconi has steadily climbed the ranks to become one of the team’s top pitching prospects. After making his major league debut on August 2, 2023, he appeared in seven games—four of them as a starter—showcasing his potential on a big stage.
Cecconi’s introduction to the major leagues was marked by the invaluable mentorship of D-backs pitching coach Brent Strom. Reflecting on their relationship, Cecconi said, “Strom’s a lot of fun to work with. He’s extremely knowledgeable and explains things in a way that I can grasp. It’s not just black and white; there’s some gray area. We tinker with various aspects of my game to see what works. Working with him has been a fantastic experience, and I’ve definitely developed under his guidance last year.”
One of the most memorable moments of Cecconi’s early career was his unique first career strikeout. Facing his first batter, he delivered a full-count pitch that struck the knob of LaMonte Wade Jr.’s bat, deflecting into the lap of catcher Jose Herrera. Initially ruled a hit-by-pitch, a D-backs challenge overturned the call to a foul tip, marking an unforgettable beginning for Cecconi. “In that first inning, I couldn’t feel my hands or feet. The adrenaline was overwhelming,” he recalled. “I was fortunate to get the strikeout in such a bizarre way.”
Cecconi also had the opportunity to pitch in the postseason during the National League Championship Series against the Philadelphia Phillies. He contributed a scoreless inning in both Game 2 and Game 5. “It was unlike anything I’ve experienced before. The atmosphere and competitiveness were incredible. I can’t wait to do it again,” he said, expressing his desire to return to that high-pressure environment.
This offseason, Cecconi set specific goals, particularly focusing on increasing the velocity of his slider. The Diamondbacks provided data illustrating significant differences in hit outcomes based on slider velocity. A Statcast analysis from last season showed that his slider’s average velocity in two starts with Triple-A Reno has increased to 85.1 MPH. “I’m throwing with full intent and velocity each time,” he explained, aiming for a slider that is sharp, firm, and effective.
In addition to his slider, Cecconi has been working on his changeup, drawing inspiration from teammate Merrill Kelly, who boasted one of the best changeups in the majors last season. This year, he has increased his changeup usage to 13.6%, more than double the 6.7% from the previous season. Early results indicate improved movement, with an additional inch and a half of fading action and an extra inch of drop. Developing this third pitch is crucial for Cecconi’s long-term success.
As the 2024 season begins, Cecconi finds himself in a competitive environment for the fifth starter role, ultimately losing out to Ryne Nelson and Tommy Henry. He was optioned to Triple-A Reno on March 18, with a focus on maintaining velocity deep into games and refining his slider and changeup. Cecconi understands that Reno presents unique challenges due to its high elevation and unpredictable weather conditions.
He has shifted his mindset, emphasizing the process over immediate results. “I’ve learned not to judge my outings solely based on earned runs. Sometimes you execute a perfect pitch, and it gets hit out in tough conditions. I’m focusing on developing the skills the D-backs have emphasized: my slider, changeup, and velocity maintenance. Concentrating on these aspects will lead to long-term improvement, rather than getting discouraged by a mishit home run.”
As Cecconi looks ahead to the 2024 season, he is committed to his growth and ready to seize opportunities when they arise. With a strong work ethic and determination, he remains optimistic about his future in the majors, excited to contribute to the Diamondbacks’ success.
