Roa, the Reds' 2020 second-round pick (No. 48 overall), missed last fall's instructional league while recovering from a sports hernia surgery but is fully healthy now, Bobby Nightengale of The Cincinnati Enquirer reports.
Roa regained his 96 mph fastball in live batting practice this spring, after starting to lose some of that velocity in his last two collegiate outings before the draft. He's expected to begin his minor league career at Low-A Daytona in May.
