The Washington Nationals signed veteran right-hander Lucas Sims to a one-year deal on Wednesday.

Terms were not released by the team but The Washington Post said it’s worth $3 million.

“His fastball’s up in the mid-to-upper 90s, his slider’s really, really effective,” Nationals manager Dave Martinez said. “We’ve got to get him in the zone. The biggest key is the walks. But we feel like we can help him and he can do that. He’s not afraid, I can tell you that right now.”

To make room for Sims on the 40-man roster, the Nationals transferred right-hander Mason Thompson to the 60-day injured list. Thompson had Tommy John surgery in March 2024.

Sims, 30, went 1-6 with a 4.38 ERA in 58 relief appearances last year for Cincinnati and Boston, which acquired him at the trade deadline in July.

Sims is 22-19 with a 4.50 ERA and 12 saves in 245 career games (14 starts) with Atlanta (2017-18), Reds (2018-24) and Red Sox.
