Nationals Sign Lucas Sims

2:05pm: The deal is for $3MM, per Andrew Golden of The Washington Post.

10:03am: The Nationals made a late addition to their bullpen Wednesday, announcing the signing of right-hander Lucas Sims to a one-year contract. Righty Mason Thompson, who had Tommy John surgery last March, was placed on the 60-day injured list to open a spot on the 40-man roster. Sims is represented by TWC Sports.

Sims, 31 in May, has spent most of his career with the Reds but was traded to the Red Sox at last year’s deadline. That deal didn’t work out especially well for Boston, as they gave up prospect Ovis Portes in exchange, while Sims then posted a 6.43 earned run average over 15 appearances around a three-week absence for a lat strain.

The Nats are surely looking beyond that unfortunate finish to his 2024 campaign. From 2019 to 2021, Sims tossed 115 2/3 innings for Cincinnati with a 4.05 ERA. He had a huge 35.2% strikeout rate over those seasons, though he undercut that somewhat with his 10.1% walk rate and some long balls.

He had a 50.6% fly ball rate in that stretch, with league average usually falling in the 35-40% range. For a guy who played his home games in homer-friendly Great American Ball Park, that wasn’t ideal and perhaps masked his true talents. He had a 3.69 FIP and 3.15 SIERA in that time. However, he strangely had a 3.75 ERA at home in those seasons but a 4.34 mark on the road.

Since then, his results have been a bit less impressive. His 2022 was largely wiped out by back issues, which culminated in surgery to repair a herniated disc. He only made six appearances that year. He returned to have a healthy 2023, tossing 61 innings with a 3.10 ERA, but his strikeout rate dropped to 27.9%. That was still above average but a notable drop from his previous work. His walk rate also ticked way up to 15.1%. A tiny .212 batting average on balls in play seemed to help him that year, which is why he had a 4.37 FIP and 4.58 SIERA.

He then posted a 3.57 ERA with the Reds last year, though with his strikeout rate falling again to 26%. His walk rate improved to 13%, a drop from the prior year but still a few ticks above average. As mentioned, he was then dealt to the Red Sox and finished the year on a down note.

Sims is a risky bet given that inconsistency but it will presumably be a fairly modest investment on the heels of his 2024 season. If he can engineer a bounceback this year, it would turn into a nice buy-low move for the Nats.

Some observers expected Washington to have an aggressive winter, but that hasn’t really come to pass. The rebuilding club has graduated a number of young players to the majors in recent years but that hasn’t pushed them to slam on the gas pedal. They have made a few additions but mostly of the short-term variety. Nathaniel Lowe was acquired to play first base and can be controlled through 2026, though he could also be traded or non-tendered depending on how things go this year. The Nats also signed Trevor Williams and Shinnosuke Ogasawara to relatively modest two-year deals and gave one-year pacts to Michael Soroka, Josh Bell, Amed Rosario, Jorge López and Paul DeJong.

In the bullpen, López and Derek Law figure to be the veteran anchors. Apart from that, it’s fairly wide open. Colin Poche is in camp as a non-roster invitee and could give them a bit more experience. Guys like Jose A. Ferrer, Eduardo Salazar, Zach Brzykcy, Evan Reifert and Orlando Ribalta are on the 40-man but no one in that group has more than 66 innings of big league experience. If the Nats and Sims get a deal done, he can join Law, López and Poche as the experienced arms in the group.

If the Nats aren’t in contention at the deadline, all of those veteran arms would be logical trade candidates. Both Law and López are slated for free agency at season’s end. Assuming Sims is only talking about a one-year deal, that would be true of him as well. Poche’s service time count is at five years and 114 days, meaning he’s just 58 shy of the six years needed for automatic free agency. If he’s on the roster before the deadline, then he would be on pace for free agency at season’s end as well.

MassLive.com’s Chris Cotillo first reported that the Nats and Sims were closing in on a deal. Mark Zuckerman of MASNsports.com reported that Sims had arrived at Nats camp and was signing a major league contract.
