Parker was promoted to High-A Wilmington on Monday, Matt Weyrich of NBC Sports Washington reports.
Parker was Washington's fifth-round pick in 2020. He's displayed the strikeout stuff the Nationals were hoping to see, having fanned 85 while posting a 4.08 ERA across 57.1 innings with Low-A Fredericksburg. He'll look to continue punching out batters at a high rate with Wilmington.
