2:05 pm: The Astros have now announced both claims. In corresponding moves, they transferred right-handers Luis Garcia Jr. and Penn Murfee to the 60-day injured list. Both pitchers underwent elbow surgery last summer and won’t be available for a few more months, at least.
12:27 pm: The Astros are set to make a pair of waiver claims. Neither has been formally announced by the club just yet, but Chandler Rome of The Athletic reports that Houston is claiming right-hander Miguel Diaz off waivers from the Tigers, who’d designated him for assignment last week. Ari Alexander of KPRC-2 in Houston further reports that the ’Stros are claiming catcher/outfielder Cooper Hummel, who was designated for assignment by the Giants last week.
Diaz, 29, has pitched in parts of six big league seasons — four with the Padres and two with the Tigers. He tossed 14 innings out of the Detroit ’pen in 2023, allowing just one run on eight hits and five walks with 16 strikeouts. It was a brief but dominant showing that surely enhanced his standing within the organization and gave him a chance to break camp with the 2024 club. However, Diaz struggled this spring, surrendering five runs on ten hits and five walks in 8 1/3 innings.
Originally selected by the Padres (by way of a trade with the Twins) out of the Brewers organization in the 2016 Rule 5 Draft, Diaz’s big league career began in rocky fashion. That was understandable, given that San Diego carried a then-22-year-old Diaz on the roster all season after plucking him directly out of A-ball. He pitched just 66 2/3 innings in his first three seasons, logging a lowly 6.62 ERA. The Friars non-tendered him in 2019 to remove him from the 40-man roster but quickly re-signed him.
In 2021, Diaz returned to the majors with 42 effective innings out of the San Diego ’pen. Over the past three seasons, he carries a 2.87 ERA, 27.1% strikeout rate, 10.8% walk rate and 41.9% ground-ball rate in 59 2/3 innings. Diaz is out of minor league options, so he’ll head directly to the Houston bullpen as he cannot be sent to the minors without first passing through waivers. If he can demonstrate some staying power in manager Joe Espada’s bullpen, he can be controlled through the 2027 season via arbitration.
Hummel, 29, has bounced from the Mariners, to the Mets, to the Giants and now the Astros since the end of the 2023 season. He appeared in 10 MLB games last year and came to the plate 26 times with Seattle. He also received a brief look with the D-backs in 2022, and he’s posted an overall .166/.264/.286 line in 227 career plate appearances.
Ugly as that small-sample slash line may be, Hummel turned in a .262/.409/.435 batting line in Triple-A last year and drew walks at a massive 18% clip. His ability to play both catcher and corner outfield gives him a relatively uncommon brand of versatility. Hummel has logged more than 1800 innings in left field, 1054 frames behind the plate, 508 innings at first base and another 296 innings in right field. Add in that he has a minor league option remaining, and he’s an interesting depth piece even if he hasn’t yet produced at the big league level.
