Right-hander Tyson Miller has been outrighted by the Cubs to Triple-A Iowa, according to his transactions tracker at MLB.com. That indicates he cleared waivers after being designated for assignment last week. He has the right to elect free agency, though it’s not yet clear if he will exercise that right.
It’s a bit of a surprise to see no one take a flier on Miller as he’s coming off a strong season. He logged 62 innings for the Mariners and Cubs last year, allowing just 2.32 earned runs per nine. His 23% strikeout rate was around league average for a reliever while he only gave out walks to 4.7% of batters faced.
He hasn’t yet had a chance to build on that showing here in 2025. He went to Japan with the Cubs for the Tokyo Series but didn’t pitch in the official big league games. He landed on the injured list due to a left hip impingement prior to domestic Opening Day. He had been rehabbing in recent weeks, with a 2.77 ERA in 13 Triple-A innings, but the Cubs didn’t want to plug him back onto the active roster. Since he’s out of options, that meant bumping him from the 40-man.
It’s possible that major league clubs don’t have much faith in Miller being able to replicate last year’s results. There was likely some luck in his numbers, as his .203 batting average on balls in play and 81.9% strand rate were both to the fortunate side. He also averaged less than 90 miles per hour on both of his fastballs last year, a level where it’s tough to succeed in the modern game.
During his recent rehab outings, though his 2.77 ERA was good, his 19% strikeout rate and 15.5% walk rate were both subpar figures. He managed to keep runs off the board by not allowing any home runs, a feat that would not be sustainable over a larger sample.
It now seems that Miller is destined for more minor league work, since no club is currently willing to give him a big league job. That could be for Iowa if he accepts his assignment or he could head to free agency and look for opportunities elsewhere.
