ATLANTA – The Nationals have another tough pitching matchup in tonight’s game against the Braves. Not because it’s another established major leaguer like Charlie Morton or Max Fried. But because it’s a 23-year-old making his first major league start.

Right-hander Spencer Schwellenbach had his contract selected to the Braves roster this morning to make his debut tonight. It’s not the first time the Nats have faced a young pitcher making his debut, but it still proves to be difficult when there’s only so much to scout beforehand.

“He's new. He's an up-and-coming young prospect,” manager Davey Martinez said during his pregame media session on how his team is preparing to face Schwellenbach. “So we did our due diligence, watched a bunch of videos. But our guys get to face him for the first time. So for me, as a young player, as a team facing a new guy, you should be a little excited. The big thing is we gotta get him in the strike zone. He might have a little nerves. But get him in the strike zone and swing at good pitches.”

Schwellenbach, the Braves’ No. 3 prospect per MLB Pipeline, provides an especially difficult challenge because he doesn’t have a lot of film to study. A second-round draft pick out of Nebraska in 2021, he had Tommy John surgery immediately after the draft and started his minor league career last year, making 16 starts between Single-A and High-A.

He started this season at High-A Rome for eight starts before being promoted two weeks ago to Double-A Mississippi, where he struck out 51 batters in 45 innings and did not allow a run over 13 innings.
