Mason Thompson's Stats, Metrics, Game Logs, Projections & Rankings

The Washington Nationals have signed pitcher Mason Thompson to a one-year deal. The 26-year-old missed the entire 2024 season after he underwent Tommy John surgery and it is presumed that he'll miss at least some portion of the beginning of 2025 as well. Once he returns, the righty will help the Nats out of the bullpen. When Thompson last played in 2023, the former third-round draft pick pitched to a 5.50 ERA, 1.56 WHIP, and a 9.2% K-BB% in 51 appearances (54 IP). Unless he finds himself in some high-leverage role, the 6-foot-6 hurler will be off the fantasy radar until further notice.

Washington Nationals right-hander Mason Thompson (elbow) is set to be re-examined by team doctors this week after being shut down the last two weeks of camp with a sore elbow. Thompson had Tommy John surgery nine years ago as a junior in high school. He's avoided major injuries since then, but he did miss three months due to a right-biceps strain in 2022. Manager Dave Martinez admitted he's "a little concerned." Thompson was dominant at times out of Washington's bullpen, but he wasn't guaranteed a spot on this year's Opening Day roster, so his elbow injury is going to make it even tougher for him to earn a spot. He struggled through most of the second half in 2023 and finished with a 5.50 ERA and 1.56 WHIP in 51 games.

Washington Nationals right-hander Mason Thompson (elbow) has been shut down for at least two weeks with an elbow issue that he suffered over the winter, according to general manager Mike Rizzo and manager Dave Martinez. Even though Thompson will require less time to get ready because he's a reliever, this news still puts his availability for Opening Day in question. In his second full year with the Nats in 2023, he went 4-4 with a career-worst 5.50 ERA (4.03 FIP) and 1.56 WHIP with his second career save, 22 walks and a career-high 44 strikeouts in 54 relief innings. Thompson has a career 4.53 ERA and 1.54 WHIP with 82 strikeouts in 103 1/3 relief innings over his three major-league seasons and won't be a roster lock, even if he's healthy.
