Scouting Report
The San Diego Padres organization has been extra cautious with Kash Mayfield ever since taking the left-hander 25th overall in the 2024 MLB Draft. They delayed his pro debut until last April, and then the team capped his workload for Low-A Lake Elsinore tightly. Mayfield never worked more than five innings or threw more than 80 pitches in a game. His innings limit shrank further in midseason after he missed three weeks in May and June with inflammation in his pitching shoulder.
When he did take the mound, he showed a lot of promise. Over 19 games (all starts) and 60 2/3 innings, Mayfield produced a 2.97 ERA/3.06 FIP, a 34.1 percent strikeout rate, a 3.14 strikeout-to-walk ratio, and a 43.6 percent ground-ball rate. He was excellent at keeping the ball in the yard, allowing just two home runs in a hitter-friendly environment. His 10.9 percent walk rate was a blemish, if only slightly, given his youth and lack of consistent reps.
He succeeded despite working with a diminished arsenal. The San Diego Union-Tribune reported last September that Mayfield's fastball velocity was down about 3 mph from his days at Elk City (Okla.) High School; he topped out at 94 mph in the Cal League, compared to 97 mph in the prep ranks. The 21-year-old's offseason plans included adding weight and strength. That could bump the velocity back up.
Other aspects of pitching helped him compensate. The heater had lively arm-side run, and Mayfield created deception with both the extension from his 6-4 frame and a relatively low release point. A mid-80s changeup and upper-70s slider gave him excellent separation. In fact, the changeup is thought to be Mayfield's best pitch. It has big-time sink and fade, making it a weapon against right-handed batters, and his arm speed creates great deception. His mechanics are considered advanced; his motion looks smooth and repeatable.
Mayfield was one of 21 pitchers in the preliminary player pool for the Padres' Spring Breakout game on March 21 against the Chicago Cubs' top prospects. A strong outing against high-level competition would give him a nice boost ahead of his second minor-league season, which should begin at High-A Fort Wayne.
