Losing Sonny Gray and Kenta Maeda from the starting rotation would be a tough pill to swallow for any organization. Gray was the AL Cy Young runner-up, and Maeda pitched well down the stretch leading into the playoffs. Minnesota’s front office talked about adding a starting pitcher earlier in the offseason, but with the team’s self-imposed payroll cut, that would have been a tricky proposition. Free agent options were too expensive, and trading for a frontline starting pitcher often requires top prospects to be included in the deal. For those reasons, the Twins will rely on internal starting pitching options to take the next step in 2024.
Spring training is a time for pitchers to work on things, to prepare for the upcoming season. Some hurlers have worked on refining specific pitches throughout the winter and spring training games, which are the first opportunity for fans to see these offerings. Multiple Twins pitchers have unveiled new pitches this spring, but Bailey Ober’s new pitch mix might be something that can elevate him from a mid-rotation arm to a playoff-caliber starter.
During the 2023 season, Ober used a four-pitch mix, which included a four-seam fastball, changeup, slider/sweeper, and curveball. Throughout his big-league career, he has relied less on his fastball, with a 12.3% usage drop from 2021 to 2023. His changeup usage has increased in each of his first three seasons, including being his second most-used pitch last season (28%).

Last season, he saw a 5% increase in his Whiff% with his fastball, which will help set up his other offspeed offerings. Many believed he needed one more pitch, a harder breaking ball that could round out his pitch mix.
Multiple Twins pitchers have been showcasing what is viewed as a gyro slider during spring training games. Last season, Ober's slider averaged 81.0 mph; his new version of the pitch has an increased velocity of 86.0 mph, with more glove-side break. Following one of his spring appearances, he told reporters, “Cutter, slider, whatever you want to call it. Something that’s hard and goes left.” Ober has also increased his release height while keeping his extension the same. These changes have helped him to add more ride to his fastball while increasing its velocity. His pitch mix now includes five pitches, with a four-seamer, gyro slider (marked below as a cutter), sweeper, curveball, and changeup.

His Stuff+ on his spring offerings has also seen some substantial increases. His fastball ranked slightly below average last season with a 94 Stuff+, but he has increased that to a 110 Stuff+ in his start on March 2. According to Stuff+, his slider was his best pitch last season, at 99. His tweaks to that pitch have moved it to 102. During spring training, there are small sample sizes to consider with pitchers, but the changes to his pitch mix continue to be encouraging.
Earlier in spring training, I discussed the possibility of Ober being an extension candidate for the Twins. His price will likely increase throughout the 2024 season as he approaches free agency and his performance improves. The Twins need their young pitchers to take the next step if they want to win the division and make a deeper playoff run this season.
Will Ober be able to translate his improved performance into the regular season? Can he be a playoff-caliber starter that the team needs? Leave a comment to start the discussion.
