Tyson Miller: Everything you need to know

The White Sox reassigned Miller to minor-league camp Monday. Miller signed a minor-league deal with the White Sox back in January after spending the entire 2025 season at Triple-A Iowa in the Cubs' organization. Miller has appeared in 74 career games at the big-league level, logging a 3.87 ERA, 1.05 WHIP and 72:28 K:BB across 93 innings.

The White Sox signed Miller to a minor-league contract Jan. 15 that includes an invitation to spring training. After posting a 2.32 ERA and 54:11 K:BB over 62 innings between the Mariners and Cubs in 2024, Miller took a major step back in 2025. He missed ample time with a hip injury and, when healthy, never escaped Triple-A Iowa, where he was torched for a 6.27 ERA and 36:34 K:BB in 37.1 frames. Miller could bounce back and win a spot in the White Sox' bullpen, though the chances are better he opens the 2026 season at Triple-A Charlotte.

The Cubs outrighted Miller to Triple-A Iowa on Wednesday. The fact that Miller cleared waivers after being removed from the Cubs' 40-man roster is somewhat surprising, given his impressive 2.32 ERA and 0.81 WHIP across 62 innings last season. Miller has the ability to elect free agency since he's been outrighted previously, but it's unclear what his plans are.
