The Mariners announced that Bryan Woo has been reinstated from the injured list, with fellow righty Tyson Miller designated for assignment in a corresponding move.
Miller, 28, signed a minor league deal with the M’s in the offseason and was selected to the big club early in April. He has since thrown 11 2/3 innings over nine appearances with a 3.09 earned run average. He has a 26.7% strikeout rate and 2.2% walk rate. He’s been helped a bit by a .207 batting average on balls in play but his 3.85 FIP and 2.98 SIERA still suggest he’s been pretty good.
That’s a small sample size but it’s still a bit surprising that he’s been bumped off the roster, especially when the Mariners could have optioned someone like Cody Bolton or Eduard Bazardo. For whatever reason, Miller has been bumped off instead. Since he’s out of options, he had to be removed from the 40-man entirely.
The M’s will now have a week to trade Miller or pass him through waivers. The fact that he’s out of options will tamp down interest somewhat, but his decent numbers will be appealing. His 5.91 ERA in his career isn’t especially impressive but that’s in just 42 2/3 innings scattered over a five-year period. Since the start of 2021, he has a 3.85 ERA in 198 2/3 Triple-A innings, striking out 27.7% of batters faced while giving out walks at a 9.7% rate.
Miller has a previous career outright and will therefore have the right to elect free agency if he were to pass through waivers unclaimed.
