As Spring Training unfolds, the White Sox find themselves in a unique position compared to recent years. While the starting lineup seems largely set, a few key positional battles remain, particularly for backup roles in the infield, outfield, and bullpen.
One player drawing attention is relief pitcher Tyson Miller. Signed as a non-roster invitee in January, Miller brings a track record of success from his time with the Chicago Cubs and Seattle Mariners. Back in 2024, he dazzled with a 2.32 ERA and a .8 WHIP, striking out 54 batters over 62 innings-a performance that any bullpen would envy.
However, Miller's journey hit a snag in 2025 due to injuries, limiting him to just 37 innings with a 6 ERA for the Iowa Cubs. Despite having only 93 major league innings under his belt, Miller's potential to strengthen the White Sox bullpen is undeniable if given another chance.
Baseball Reference projects Miller to deliver 31 innings with a 3.70 ERA and a 1.1 WHIP this season. Such numbers would make him a valuable asset in a bullpen that has seen its share of ups and downs in recent years.
In Spring Training, Miller has already impressed with two scoreless appearances, allowing just one hit and striking out one batter. His health and performance suggest he could be a significant contributor to the White Sox bullpen. Yet, with 5 to 6 bullpen spots likely secured, competition is fierce for the remaining 2 to 3 openings.
Miller's past success, particularly in 2024, positions him as a strong contender to secure a spot. His chances are around 60%, potentially increasing if he continues to deliver strong performances throughout camp.
Should Miller not make the initial roster, starting the season in AAA is a possibility, with a call-up likely if injuries arise. His journey is one to watch, as his presence could be a game-changer for the White Sox this season.
