Mason Thompson DVOA, Advanced Stats, & Fantasy Rankings

The Washington Nationals placed right-handed pitcher Mason Thompson (elbow) on the 60-day injured list. This transaction opened a roster spot for right-handed pitcher Lucas Sims, who the team signed earlier on Wednesday. Earlier in the offseason, manager Dave Martinez expressed optimism about the right-hander, but Thompson was unable to progress enough. As a result, fantasy managers should not expect him to return to the mound until late May. Thompson is still recovering from the Tommy John surgery he underwent in March 2024. During the 2023 campaign, Thompson posted a 5.50 ERA and a 1.56 WHIP across 54 innings. He tallied just 44 punchouts. When healthy, fantasy managers should expect Thompson to have a low-leverage role in the Washington bullpen.

According to Spencer Nusbaum of the Washington Post, Nationals right-handed pitcher Mason Thompson (elbow) could be ready for Opening Day. The 26-year-old underwent Tommy John surgery last March but could be able to ramp up in time due to him being a relief pitcher. However, Thompson has yet to throw off a mound. Fantasy managers should continue to monitor his status during spring training. During the 2023 season, Thompson logged 54 innings of MLB action with a 5.50 ERA and a 1.46 WHIP. He tallied punchouts out a low 18.3 percent strikeout rate and held a high 9.2 percent walk rate. However, he generated ground balls at a strong 50.6 percent rate, placing him in the 84th percentile among qualified pitchers that season. If he were to be cleared for action, he would likely contend for a spot in the Washington bullpen.

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.
