The Nationals announced this afternoon that they’ve activated right-hander Mason Thompson from the 60-day injured list. Right-hander Zach Brzykcy was optioned to Triple-A to make room for Thompson on the active roster, while right-hander Derek Law was transferred to the 60-day IL to create a 40-man roster spot for Thompson.
Thompson, 27, last pitched in the majors back in 2023. A third-round pick by the Padres back in 2016, he made his big league debut in San Diego during the 2021 season but made just four appearances with the team before being traded to the Nationals in exchange for veteran righty Daniel Hudson at the 2021 trade deadline. Since then, he’s pitched parts of three seasons in a Nationals uniform. He’s generally been a league average reliever during his time with Washington, posting a 4.57 ERA (91 ERA+) with a 4.43 FIP in his 100 1/3 innings of work for the club.
The righty was at his best in 2022, when he posted a sterling 2.92 ERA in 24 2/3 innings of work. With that being said, that dominant performance came across a sample of just 24 2/3 innings of work and saw him post a strikeout rate of just 14.9%. 2023 saw his strikeout rate creep back up to 18.3%, but his ground ball rate dropped from 53.3% to 50.6% as his ERA ballooned up to 5.50. He figured to once again be part of the Nationals bullpen mix last year despite those lackluster numbers, but he underwent Tommy John surgery last March and has been sidelined ever since. He began rehabbing in mid-June and was promoted to Triple-A earlier this week, where he made two scoreless appearances before rejoining the Nats.
Kyle Finnegan is locked in as the club’s closer, but the team has few other solid bullpen options and a strong performance from Thompson could allow him to work his way into the club’s late-inning mix going forward. Departing the roster to make room for Thompson is Brzykcy, who made his MLB debut last year and has a 7.40 ERA in 20 2/3 innings of work this year. He’ll remain as optionable depth at Triple-A for the Nats going forward. As for Law, the right-hander has been sidelined all season due to forearm inflammation. Things may have taken a turn for the worse recently, however, as MASN’s Mark Zuckerman writes that Law has been dogged by frequent setbacks throughout his rehab and is headed for an MRI exam to make sure the injury hasn’t worsened since he was initially placed on the shelf. Even if the MRI doesn’t reveal structural damage, Zuckerman writes that Law could still be sidelined for quite some time due to the issue.
