Roster Watch: Can Tyson Miller Steal A White Sox Bullpen Spot?
This Spring Training is a bit different from the last few years, as there is a bit more set in stone on the 26-man roster for the White Sox. However, there are certainly still some key positional battles. For the first time in what seems like a very a long time, there aren’t roster battles at practically every position, as the White Sox likely have their starting lineup locked up. However, there are still a few backup spots in the infield and outfield up for grabs, as well as a few spots in the bullpen.
As we get closer to the season starting, we will look at each fringe roster player and their chances to make the team out of Spring Training. Relief pitcher Tyson Miller is the next player we will take a look at.
Miller was signed as a non-roster invitee back in January after a few successful major league seasons. One of his most successful seasons came for the crosstown rival Chicago Cubs. In 2024 between the Seattle Mariners and Chicago Cubs, Miller posted a stellar 2.32 ERA and a phenomenal .8 WHIP. He also struck out 54 batters in 62 innings, while walking just 11 batters. These are all-star level numbers out of the bullpen.
Unfortunately for Miller, he was hurt for most of the 2025 season. He threw just 37 innings for the Iowa Cubs, where he had a 6 ERA. Miller has just 93 major league innings under his belt and has bounced around a few teams, but he could potentially be one of the better White Sox relievers with another extended look.
According to Baseball Reference’s projections for Miller, they predict he will throw 31 innings of 3.70 ERA baseball with a 1.1 WHIP. This would be a huge addition to the bullpen, as that would have been one of the better performances out of the bullpen in the last few years.
So far Miller has looked good in camp, as he has posted two scoreless appearances. In those two innings, he’s given up one hit and struck out one batter. Overall, he looks healthy and could be a legitimate piece in the White Sox bullpen this season. However, unlike most years, the bullpen doesn’t have a ton of open spots.

The White Sox have arguably 5 to 6 bullpen spots already sent in stone, leaving just 2 to 3 spots up for grabs. Miller can certainly win a spot out of Spring Training, but it may take all the way up until the end of Spring Training to know for sure.
Miller has had good production in the major leagues as recent as 2024, so him having another good season wouldn’t be out of the ordinary. Out of all the non-roster bullpen position players, he may have the best chance to win a spot. I give him about a 60% chance of securing a spot, with that potentially going higher if he continues to put up zeros when he pitches.
If he doesn’t make the team, he could start the season in AAA and make his way up to Chicago if there is an injury. Miller is a very interesting player and I certainly would like to see him break camp with the team.
