https://northsidebound.com/2023/02/26/behind-the-scenes-with-five-pitchers-ready-to-take-the-next-steps/Really nice article with what 5 pitchers are targeting for improvement this offseason.
Palencia, better slider/curve separation, better command.
Little (Luke): “Pitch design we’ve been really focusing on getting more depth on the change up which is basically a splitter now. And slider looking to get more shape on that. Fastball trying to get more ride." And be in physical shape to handle more innings.
Riley Thompson: Add a sinker, tweak his slider, (bullet "gyro" slider, not sweeper.). And throw more changeups.
McCollough: “Main goal being velocity. .... I used the core velocity belt to help with this. I was happy with the results of the velocity as it was 94-96 throughout instructs”, McCullough said. “Everything felt smooth and more compact”.
Noland: Changup.
