The Nationals began the process of trimming down their 40-man roster for the start of the offseason this evening, announcing four players cleared outright waivers in Paul Toboni’s first official transactions since being named president of baseball operations.

Right-handers Eduardo Salazar and Mason Thompson, left-hander Shinnosuke Ogasawara and catcher CJ Stubbs were dropped from the 40-man roster, with Ogasawara and Stubbs assigned outright to Triple-A Rochester. Salazar and Thompson refused their outright assignments and instead declared for free agency, leaving the organization in the process.

All major league clubs must activate players who ended the season on the injured list following the World Series, and typically that requires some other maneuvering to make sure they do not exceed the 40-man roster limit for the offseason. Today’s moves leave the Nationals with 36 active players, plus four more under club control who ended the year on the 60-day IL: Josiah Gray, DJ Herz, Drew Millas and Trevor Williams. (Derek Law also was on the 60-day IL, but he’s set to become a free agent after the World Series and will automatically come off the roster.)

Thompson also ended the season on the IL with right biceps tendinitis, a frustrating conclusion to a frustrating season for the 27-year-old reliever, who in his return from his second Tommy John surgery produced an 11.81 ERA and 2.625 WHIP in 14 big league appearances. Originally acquired from the Padres for Daniel Hudson in one of former general manager Mike Rizzo’s flurry of 2021 trade deadline deals, Thompson ends his Nationals tenure with a 7-9 record, 5.27 ERA and 1.640 WHIP in 116 games.

Salazar, a waiver claim from the Mariners during the 2024 season, showed initial promise with a 2.96 ERA in 25 appearances but struggled this season to the tune of an 8.38 ERA in 30 games while bouncing back and forth between D.C. and Rochester.

Forget about the notion five weeks ago Andrew Alvarez might somehow pitch five scoreless innings in the major leagues. The mere notion at that time that Alvarez might pitch in the major leagues at all sounded pretty ludicrous.

The 26-year-old left-hander seemingly had stalled out at Triple-A Rochester, winless through his first 19 starts of the season, his ERA in the high 4.00s. As much as the Nationals needed all the pitching help they could get, Alvarez didn’t figure to make the list of prime candidates for a promotion.

Those who know him well, though, knew all along Alvarez wasn’t about to give up on his dream. He was going to find a way to put himself back in the mix somehow, some way. And when his moment did finally come this afternoon, he wasn’t going to waste it.

With five scoreless innings of one-hit ball, Alvarez made his major league debut one to remember. And thanks to some help from the Nationals lineup and bullpen, he was appropriately rewarded for it with a 2-0 victory over the Marlins, snapping the team’s eight-game losing streak in the process.

"It's hard to put into words," he said. "I'm just blessed and thankful. The team played awesome, and at the end of the day, the team won. It's such an honor to be a part of this. You dream of this as a kid. And to have it come to fruition is no more than a miracle."
