Rangers Sign Patrick Corbin

The Rangers announced that they have signed left-hander Patrick Corbin to a one-year major league deal. The ISE Baseball client’s exact guarantee isn’t publicly known but Jon Heyman of The New York Post reports that it will be a slightly more than $1MM, with incentives worth around a million as well. Righty Jon Gray was transferred to the 60-day injured list as the corresponding move.

For the Rangers, this would appear to be a quantity-over-quality move. Corbin’s past few years haven’t been good on a rate basis, but he has been an effective innings-eater for the Nationals. The southpaw signed a six-year, $140MM deal with Washington going into 2019. He had just wrapped up a stellar season for the 2018 Diamondbacks, tossing 200 innings with a 3.15 earned run average. While his strikeout rate had previously hovered around 20%, he punched out 30.8% of opponents that year.

His first year as a Nat could hardly have gone much better. He logged 202 innings over 33 starts in the regular season with a 3.25 ERA, 28.5% strikeout rate, 8.4% walk rate and 49.5% ground ball rate. He logged another 23 1/3 innings in the postseason as the Nats charged all the way to the World Series and won it all for the first time in franchise history.

But his results declined in 2020 and never really recovered. His strikeout rate fell to 20.3% that year and his ERA climbed to 4.66. In the four full seasons since then, he has a combined 5.71 ERA, 17.7% strikeout rate and 7.3% walk rate. He didn’t post an ERA below 5.20 in any of those four campaigns.

But as alluded to earlier, he at least compiled bulk innings for the Nats. He has actually been about as reliable as a pitcher can be over the past decade. He missed the 2014 season due to Tommy John surgery. He was activated in July of 2015 and tossed 85 innings that year. The Snakes used him as a swingman in 2016, with Corbin logging 155 2/3 innings that year over 24 starts and 12 relief appearances. Since then, he has made at least 31 starts and logged at least 171 innings in every full season, in addition to making 11 starts in the shortened 2020 season. Any pitcher can get hurt at any time, but it’s hard to find a better track record of health in today’s game. From 2016 to 2024, Corbin’s 1,492 innings are second in baseball behind Aaron Nola.

A dependable back-end starter has some understandable appeal to the Rangers. The aforementioned Gray suffered a wrist fracture and is going to be out for a quite a while. Today’s transfer to the 60-day IL means a return in late May is the best-case scenario. Cody Bradford is shut down with some elbow soreness and faced an uncertain path back to health.

They could still have a competent rotation without those two, though there are questions with each candidate. Nathan Eovaldi has been largely healthy for the past few years but has two Tommy John surgeries on his track record and is now 35 years old. Jacob deGrom has missed most of the past two seasons due to Tommy John surgery and had plenty of issues before that as well. He hasn’t gone past 92 innings in a season since 2019 and turns 37 in June. Tyler Mahle also missed most of the past two seasons due to Tommy John surgery and has been battling forearm soreness in camp.

Prospect Kumar Rocker is a candidate to step up and take a job but he also missed most of the past two years due to his own TJS. Jack Leiter is impressing in camp but control still seems to be an issue, as it has been throughout his minor league career. Dane Dunning is coming off a rough year, as is non-roster invitee Adrian Houser.

A guy like Corbin taking the ball with regularity could be useful for a group like that with so many question marks. It’s also possible that he’s been better in recent years than it would appear. As mentioned, he has a 5.71 ERA over the past four years. However, his .328 batting average on balls in play and 67.4% strand rate were both on the unlucky side. His 4.99 FIP and 4.60 SIERA in that span suggest his ERA might have been inflated by about a full run. The Nationals had a team-wide -82 Defensive Runs Saved and -96 Outs Above Average during that four-year span, perhaps explaining some of the bad luck and extra runs crossing the plate.

If Corbin can take the ball and provide half-decent innings, that could be useful to the Rangers, especially at this price point. They are clearly trying to avoid the competitive balance tax in 2025, which has mostly limited them to fairly modest dealings this offseason. RosterResource projects their CBT number at $235MM, only about $6MM below this year’s $241MM base threshold of the tax. Corbin’s salary won’t move that very much, since he’s barely making more than the $760K league minimum.

Presumably, Corbin won’t be an option for the Rangers right away. He’ll need a few weeks to get himself into game shape, so he’ll likely start the season on the injured list, or perhaps he will consent to a brief optional assignment to start the year. President of baseball operations Chris Young tells Kennedi Landry of MLB.com that Corbin’s wife is due to have a baby in the next 24 to 48 hours, so he won’t even be joining the club in Arizona. He will instead join the club in Texas after they break camp.

Until Corbin is ready, the Rangers will likely give Rocker and Leiter some legit chances at locking down jobs. If those don’t work or other injury situations pop up, Corbin will slot into the rotation mix and ideally stabilize things.
