Right-hander Miguel Díaz has been released by the Astros, according to his transactions tracker at MLB.com. He’s now a free agent and will be free to pursue opportunities with any club on the open market.
Díaz, 29, was claimed off waivers from the Tigers in April. He tossed one scoreless inning for the Astros before getting designated for assignment. He cleared waivers and elected free agency but then stayed in the organization by inking a minor league deal with the Astros.
He reported to Triple-A Sugar Land but didn’t fare well there, at least in terms of results. He tossed 14 innings over 13 appearances but allowed 15 earned runs. That leads to an earned run average of 9.64 that’s probably misleading. His .392 batting average on balls in play and 40% strand rate were both on the unlucky side of average. He only struck out 15.2% of batters faced but also only walked 7.6% and didn’t allow a home run, which is why his 3.62 FIP was far below his ERA.
All of that is a small sample and in the hitter-friendly Pacific Coast League as well. His big league track record dates back to 2017 and includes 127 1/3 innings with a 4.81 ERA. That number is a bit skewed by his rookie season, when he was a 22-year-old Rule 5 pick of the Padres despite never having pitched above A-ball before. He tossed 41 2/3 innings for the Friars that year with a 7.34 ERA.
Since that campaign, he has thrown 85 2/3 innings in the majors with a 3.57 ERA, scattered over several campaigns with the Padres, Tigers and that one inning with the Astros. His 10.9% walk rate in that stretch is on the high side but he also punched out 27.7% of batters faced. From 2021 to 2023, he also tossed 137 2/3 innings in the minors. His 4.97 ERA in that time isn’t especially impressive and his 11.3% walk rate was on the high side, but his 26.2% strikeout rate was quite solid.
Despite debuting way back in 2017, Díaz is still about six months shy of his 30th birthday. He has exhausted his option seasons but has just around three years of big league service time. His results haven’t been perfect but he’s generally been able to rack up strikeouts wherever he’s gone, apart from his small sample of work for Sugar Land this year.
