From Prospect to the Show: Rangers Call Up Jose Corniell in Cleveland Series
The Texas Rangers closed out September with a shake-up to their roster, but all eyes are on one name: Jose Corniell. The 22-year-old right-hander, once a raw international signee and later a Rule 5-protected arm, is finally getting his chance at the big-league level.
A First Call That Means Everything
Corniell’s promotion comes as the Rangers wrap up their final series of the season against the Guardians. While the veteran pieces around him shuffle in and out — Josh Smith to the paternity list, Donovan Solano added for infield depth, Chris Martin and Cole Winn shut down with injuries — Corniell’s arrival feels different.
For Texas fans, this isn’t just another September roster move. It’s the first glimpse of what could be a long-term piece of the pitching staff.
The Road to Texas
Corniell’s journey hasn’t been straightforward. Originally signed by the Mariners in 2019, he was traded to the Rangers in 2021 for Rafael Montero before ever throwing a professional pitch. The pandemic wiped out his debut season, and the two years that followed were a struggle.
Then came the breakthrough in 2023. Corniell flashed his potential in the low minors, enough for the Rangers to protect him on the 40-man roster that winter. But the excitement was put on pause last June when he underwent UCL surgery.
Now, after months of rehab, he’s back — and sharper than ever. Between Double-A and Triple-A this summer, Corniell logged 32 1/3 innings with 34 strikeouts, showing the swing-and-miss stuff that once made him such a promising signee.
What His Role Looks Like
Don’t expect Bruce Bochy to hand Corniell the ball for a crucial start — not with Cleveland fighting for the AL Central crown. More likely, he’ll make his debut out of the bullpen, perhaps as a long reliever if the situation opens up. Still, even one inning in a Rangers uniform would mark the payoff of years of uncertainty and work.
A Veteran Bows Out
While Corniell steps in, veteran reliever Chris Martin steps away. The 39-year-old Arlington native has been diagnosed with thoracic outlet syndrome, ending his season and potentially his career. Martin posted a 2.98 ERA in 42 1/3 innings this year, even recording his 400th career strikeout before going down.
If this is the end, the hometown pitcher leaves the game with a 3.33 ERA over 10 seasons and the respect of teammates and opponents alike.
Looking Ahead
With Corniell, Solano, and Luis Curvelo added to the roster, the Rangers will play out the season with a mix of youth and experience. They may not be chasing October this year, but Texas fans will get a first look at another arm who could shape the club’s future.
