Uncommitted. 6-foot-3, 190-pounds. Walsh had a strong and efficient outing at the Georgia Dugout Club tournament. He went 5 innings, striking out 7 while only allowing 4 hits. Walsh stayed in the zone producing weak contact and showed strikeout stuff. Walsh displayed a low to mid 80’s FB topping out at 85, mixed with a solid curveball with good depth. He showed the ability to mix in a changeup when needed. Walsh showed smooth mechanics, really finishing his pitches and getting his backside through well. Walsh will be fun to watch as he has plenty of room to progress.
