Jones has worked on a two-seam fastball this offseason and will test the pitch in spring training games, Alex Stumpf of MLB.com reports.

EDGE Analysis

Jones had a breakout 2024 season, but his 1.3 HR/9 was a blemish in his skills profile. Like teammate Paul Skenes, Jones is working on a pitch with sinking action in an attempt to keep the ball in the yard more effectively. That could also hurt his potential strikeout upside, though he didn't commit to using it in the regular season.
