Twins Video
Driveline Baseball has become something of a household name in baseball circles in recent years, as it’s extended its reach from youth baseball to the MLB level. Using the newest technology and data available in the baseball world, Driveline has its fair share of success stories among professional pitchers. In 2023, Joe Ryan and Tyler Mahle are looking to become the newest names added to the list.
Mahle and Ryan likely had very different goals in mind this offseason and each opted to take them to the pitching labs of Driveline Baseball. We often hear little about what specifically pitchers are working on during their offseason routine, but given the reputation of Driveline and the details that we’ve received, this news should be exciting to Twins fans.
Tyler Mahle
The first thought when hearing his name tied to Driveline was a recovery plan for whatever shoulder ailment ended his 2022 season. Instead, Mahle went about his business as usual this offseason, looking to make tweaks to his repertoire. Even when healthy last season, he seemed to be missing just a small piece of the puzzle.
Mahle opted to revamp his slider after the 2022 season. He has what’s classified as a slider and a cutter, though it’s fair to wonder whether both are the same pitch that classify differently at times, as the “slider” averaged a bit less velocity than the “cutter”. At any rate, these were his two worst pitches by most measures. Expected Batting Average and Slugging were markedly worse than his fastball and splitter for these two pitches, and it showed up in his platoon splits.
Right-handed hitters put up an OPS of .784 against the right-handed Mahle, much worse than the .602 mark against left-handed hitters. It was clear he lacked an equalizer against same-handed hitters.
From the little we can see, Mahle has added more horizontal break to his slider and less vertical break. It appears to be a new look breaking ball, which is a welcome change based on how the previous one had difficulties equalizing right-handed hitters. For how well he’s performed against left-handed hitters in his career, if he can find any kind of similar success against righties, he could become a certified stud.
Joe Ryan
After being able to dominate the minors with mostly a fastball, the Twins tried to incorporate a slider to better equip Joe Ryan to start in the MLB. On the season, Ryan allowed just one less homer on the slider than he did his fastball, though he threw the slider roughly a third as much. Ryan seemed to find something to end the season, as the pitch was dominant in September by many measures including Expected Slugging and Batting Average, hard hit % etc. Ryan took that momentum to Driveline as well this winter.
For Ryan, further developing another pitch is a must. His fastball remained fantastic despite being used over 60% of the time, which means any kind of plus secondary offering would raise Ryan’s game to new heights. With the foundation he and the Twins built on the breaking ball, it’s exciting to think about what an offseason at Driveline could do for the pitch.
Ryan had more than one pitch in mind this winter. Unlike Mahle, Ryan is significantly better against same-handed hitters. His strikeouts markedly drop off, suggesting a need for a good matchup pitch for left-handed hitters. Because of this, Ryan worked on a split changeup this winter as well.
Of note, this is the same pitch that has been Tyler Mahle’s bread and butter secondary, and is a big reason for the lack of platoon splits in his career. Traditionally the pitch is a little faster and has more late life than the plain old changeup. This makes it a bit tougher to pick up by opposite handed hitters who typically have a better look at what’s coming from the pitcher. While it’s tough to say what to expect from Ryan debuting an entirely new pitch, it’s easy to look at the changeup he used just 12% of the time in 2022 and see room for improvement.
Tyler Mahle and Joe Ryan have high end upside. Both have good foundations in their repertoire, Ryan with his magical fastball and Mahle with his uncommon ability to negate platoon splits. It sounds like both went in search of the missing pieces this winter at Driveline, and it’ll be interesting to see how the new pitches look. There’s a possibility that both pitchers raise their games to new levels.
