Nationals Sign Michael Soroka

The Nationals announced that they have signed right-hander Michael Soroka to a one-year deal, which reportedly comes with a $9MM salary. The club had 40-man vacancies and didn’t need to make a corresponding move. The ISE Baseball client will reportedly be used as a starter.

Soroka, 27, came into the offseason as one of the more interesting free agents available. He found success as a starting pitcher in his early 20s, back in 2019, but missed most of the 2020 to 2023 seasons due to injuries. In 2024, he struggled badly as a starter but then got moved to a bullpen role and finished the season in very strong fashion. It could have been argued that he earned himself another shot at a rotation job or that he found a role that worked for him and should continue as a reliever, though it seems he will take another shot at being a starter next year.

Prior to his 2019 breakout, Soroka was already a name to watch. He was a first-round pick of Atlanta in 2015 and found himself on top 100 prospect lists as he climbed through the minors. He debuted with five starts in 2018 and then fully cemented himself as a big leaguer in 2019, making 29 starts and logging 174 2/3 innings while allowing 2.68 earned runs per nine. His 20.3% strikeout rate was just below average but his 5.8% walk rate and 51.2% ground ball rate were both notably better than par.

That was Soroka’s age-21 season, so it seemed Atlanta had a rotation building block for years to come. Unfortunately, the baseball gods had a miserable fate in store for Soroka’s next chapter. In his third start of the shortened 2020 season, he had to be helped off the field with a leg injury, later revealed to be a torn right achilles tendon which required surgery. In 2021, he missed some time due to shoulder inflammation and later required another surgery on his achilles. He got back on the mound in 2022 and pitched in the minors, though that season was ended due to elbow soreness. In 2023, he was frequently shuttled between Triple-A and the majors and finished the season on the IL due to forearm inflammation.

After those four years in the injury wilderness, Atlanta seemingly didn’t have much faith in Soroka bouncing back. He was flipped to the White Sox in November, part of a five-for-one trade that saw Atlanta flip multiple spare parts for Aaron Bummer in a roster clearout move.

Unlike Atlanta, Chicago was aggressively rebuilding and had more bandwidth for being patient with Soroka, hoping for a bounceback. It didn’t materialize at first. Soroka started the season with nine starts but had a 6.39 ERA in those. His 46.9% grounder rate was strong but his matching strikeout and walk rates of 12.4% were both bad.

The last of those starts was on May 12. Soroka was moved to the bullpen at that point, which is when things became very interesting. He tossed 36 innings out of the bullpen in the remainder of the season with a 2.75 ERA. His 13% walk rate was oddly high and his grounder rate was just 26.5% but he managed to punch out 39% of batter’s faced.

That came with a significant change in his pitch mix. In those nine starts, he threw 22.5% four-seamers, 30.8% sinkers, 31.9% sliders and 14.7% changeups. After moving to the bullpen, he pushed towards a fastball/slider mix, with 43.2% of his pitches being the former and 41.6% the latter. His sinker and changeup rates dropped to 10.9% and 4.3%, respectively. Despite limiting his arsenal, he was effective against hitters on both sides of the plate. Righties hit just .197/.306/.296 against Soroka the reliever while lefties mustered only a .179/.299/.286 line.

Given the amount of success he had in that relief role, it might be tempting to suggest that he should stay there, but there are also counterarguments. For one thing, despite the many twists and turns in his career, Soroka is still young. He is currently 27 and won’t turn 28 until August. He might not want to give up on the possibility of being a starter just yet.

Furthermore, teams these days don’t tend to view relief success as any kind of reason to not try a guy in a starting role. In recent years, bullpen-to-rotation conversions have become all the rage, with guys like Seth Lugo, Michael King, Garrett Crochet, Reynaldo López, Jeffrey Springs and others making the move successfully. It doesn’t always work out, with A.J. Puk being one example, but even then the downside is pretty harmless as the pitcher just lands as a viable reliever as a fallback.

The Nats should be able to give Soroka a chance to earn a rotation job, at least for a while. They have some intriguing arms but most of them are fairly lacking in experience. The quartet of MacKenzie Gore, Jake Irvin, Mitchell Parker and DJ Herz all had decent results in 2024, with each posting an ERA of 4.41 or lower. However, Gore’s 372 2/3 career innings are the most of the bunch. Irvin is at 308 while Parker and Herz just debuted in 2024 and are below 200. Josiah Gray had UCL surgery in July and won’t be a factor until late in the 2025 season, if at all. Cade Cavalli missed all of 2023 and 2024 recovering from Tommy John surgery and it’s unknown what kind of workload he can take on next year.

Washington can give Soroka a rotation gig to start the year and see how things go. If he struggles out of the gate, they can push him to the bullpen and give those starts to one of the younger pitchers. But if things go well, he can be very valuable for the Nats. If they are able to emerge from their ongoing rebuild, he can be a part of that, but he could be a midseason trade candidate even if the club isn’t ready for that step yet. Even if he’s pushed to a relief role, he could still be an interesting deadline trade candidate.

It’s also theoretically possible that he pitches his way into consideration for a qualifying offer at season’s end, as even mid-rotation or back-end guys like Nick Pivetta, Luis Severino and Nick Martinez got QOs this year. In that scenario, Soroka could stay with the Nats all year and help them make a contending push while also providing some future value at the end of the year, though that will be a concern for another day.

At the start of the offseason, MLBTR predicted Soroka for a two-year deal worth $14MM. He has settled for a lesser guarantee but on a stronger annual value, with the chance to return to the open market a year from now. For him personally, that could be a lucrative bet, as it’s possible he will have much more earning power at the end of the 2025 season.

Ken Rosenthal of The Athletic first reported that the Nats and Soroka were in agreement. Robert Murray of FanSided reported that it was a one-year deal worth $9MM.
