Andrew Alvarez turned a season of call-ups and demotions into a strong case for a spot in Washington’s 2027 rotation. The left-hander improved markedly after the All-Star break, showing he can handle a starter’s workload. The Nationals see room for more growth, especially if he can add velocity and better command his fastball.

By the Numbers
  • Alvarez went 2-6 with a 3.43 ERA in 25 appearances, including 17 starts.
  • After the All-Star break, he posted a 2.97 ERA over 63⅔ innings; opponents hit .201.
  • Across 10 starts from July 27 to Sept. 19, he had a 2.14 ERA and held opponents to a .172 average.
  • He went 56⅔ innings without allowing a home run, the fourth-longest such streak in Nationals history (2005-present).
Yes, But

Alvarez’s late-season results strengthened his case, but his strike-throwing and fastball remain areas to improve. His 92.1 mph average fastball velocity ranked in the 16th percentile, and the pitch generated a 12.6% whiff rate. Nationals manager Blake Butera believes better fastball command—and potentially more velocity—could help Alvarez get more swings and misses.

What's Next

Alvarez plans to use the offseason to improve and will have to compete again for a 2027 rotation spot. The Nationals are counting on continued development of his fastball and overall pitch mix.

Bottom Line

Alvarez has earned a serious look, not a guaranteed place in the rotation. His second-half surge gives Washington reason to invest in his development; turning that momentum into a reliable fastball could decide how much responsibility he gets next season.
