The Nationals optioned Alvarez to Triple-A Rochester after Sunday's 3-0 win over the Giants.
Alvarez was called up from Rochester ahead of Sunday's series finale and played a pivotal role while working out of the bullpen. The southpaw tossed the final 4.1 innings of the team's combined shutout of the Giants, allowing three hits while striking out five en route to earning the win. Alvarez posted a 2.31 ERA and 1.11 WHIP with 20 strikeouts over 23.1 innings in five starts with the Nationals in 2025, and considering how well he pitched Sunday, he likely won't have to wait long for another shot with the big-league club. In the meantime, Alvarez will slot back into the rotation at Rochester.
