The Athletics announced that they have signed right-hander José Leclerc to a one-year deal. It’s reportedly a $10MM guarantee for the former Ranger. Fellow righty Will Klein has been designated for assignment to open a roster spot.

Leclerc, 31, jumps across the American League West. He had spent his entire career with the Rangers up until now. During his time in Texas, he has shown flashes of excellence as a reliever. In general, his career has been defined by a strong ability to get strikeouts but also some poor control.

Overall, he has 360 1/3 innings under his belt to this point, having allowed 3.27 earned runs per nine. His 31.2% strikeout rate is a very strong number but his 13.2% walk rate is much higher than average.

That lack of control has made his performance somewhat inconsistent. He was once the primary closer for the Rangers, having earned 12 saves in 2018 and 14 more the year after. But he missed essentially all of the next two seasons. A right teres muscle tear limited him to just two appearances during the shortened 2020 season. He then required Tommy John surgery in March of 2021, which wiped out that whole year.

Since coming back, he hasn’t been able to retake the closer’s role, with just 12 saves over the past three years combined. However, his control has actually been better lately, at least relative to his own previous performance. He had a 14.9% walk rate as of his Tommy John surgery. Since coming back, he has only walked 11.3% of batters faced. That’s still a high number, as league average is usually in the 8-9% range, but it was a noticeable improvement.

From the start of the 2022 season to the present, he has a 3.36 ERA, 29.2% strikeout rate and, as mentioned, an 11.3% walk rate. His 3.60 FIP and 3.58 SIERA are marginally higher than his ERA, likely because his .271 batting average on balls in play and 76.5% strand rate are a bit on the fortunate side. He also formed a notable portion of the Texas relief corps during their World Series run, tossing 13 2/3 innings with a 3.29 ERA during the 2023 postseason.

His ERA did jump to 4.32 in 2024, but that doesn’t seem to have been his fault. His .314 BABIP was actually on the high side last year. His 30.9% strikeout rate and 11.1% walk rate were pretty close to what he has done before. His 3.48 FIP and 3.26 SIERA both suggest he was pretty similar to the guy he was going into the year.

In addition to the strikeouts, Leclerc has often been good at avoiding damage. Statcast had his hard hit rate at 30.7% last year, which placed him in the 96th percentile of qualified pitchers. That was actually above his career rate of 29.3%. His 87.4 mile per hour average exit velocity was in the 84th percentile last year. Again, his career average of 86.4 mph is even better. The pitch velocity on his four-seam fastball and sinker both averaged around 95 miles per hour, while he also mixed in a slider, cutter and changeup.

It’s an interesting buy-low move for the A’s, since they are grabbing Leclerc after a rough year in the ERA department, but with encouraging numbers under the hood. They already have one of the best closers in the league in Mason Miller, so they can use Leclerc in a setup capacity.

The club has been surprisingly aggressive this winter in bolstering the roster. They gave a big deal to sign free agent right-hander Luis Severino, acquired lefty Jeffrey Springs from the Rays and signed outfielder/designated hitter Brent Rooker to a five-year extension.

Cynically, this likely has a lot to do with the club having to spend its revenue-sharing money in order to avoid a grievance from the MLBPA, but they are making some notable improvements nonetheless. The team went 32-32 in the second half of 2024 after graduating a lot of young talent to the majors, so it’s not impossible for them to be a surprise contender in 2025, especially with their new additions. Though if that doesn’t come to pass and they are still shy of contention, Leclerc could then be traded prior to the summer deadline as long as he’s having a strong year, since he’s only on a one-year deal.

Leclerc’s pact takes the club’s payroll to $74MM and their competitive balance tax number to $106MM, per the calculations of RosterResource. Reporting has indicated the club needs a CBT number of $105MM to avoid that grievance, but a final CBT calculation doesn’t come until the end of the year. The A’s might want to push it a bit further, just in case they end up trading players like Leclerc at the deadline and knocking that number down. Otherwise, their deadline dealings would have to be fairly revenue neutral.

Klein, 25, was one of three players that the A’s just acquired from the Royals in the Lucas Erceg trade at last year’s deadline. He didn’t have much big league experience prior to the deal and the A’s mostly kept him on optional assignment. He currently has 7 2/3 innings of MLB experience with nine earned runs allowed.

That’s obviously not a huge sample size and the A’s surely acquired Klein based on his larger sample of work in the minors. His numbers on the farm are vaguely Leclerc-esque, since he has been able to get strikeouts but has also given out plenty of walks. He has 221 1/3 minor league frames under his belt with a 5.16 ERA, 30.4% strikeout rate and 16.2% walk rate.

The punchouts are attractive but even those faded in 2024. He tossed 43 Triple-A innings on the year between the two organizations, with a 22.4% strikeout rate and the walk rate still up at 16.7%. The 3.77 ERA wasn’t bad but a .234 BABIP and 75.4% strand rate surely helped him there, which is why he had a 5.42 FIP.

The Erceg deal was considered light by many observers at the time. It can often be difficult to grade a trade so soon after it’s consummated but it doesn’t bode well for the A’s that they are now potentially moving on from one of the three players they got in return.

They will now have a week to figure out Klein’s fate, whether that’s a trade or something on the waiver wire. The waiver process takes 48 hours, so that leaves five days for trade talks. He still has a couple of option years left, meaning any acquiring club could potentially keep him in the minors until he shows improved control.

Jon Heyman of The New York Post first reported the $10MM guarantee.
