LHP Hagen Smith, Arkansas
When I watch Hagen Smith pitch, I see a player like Cardinals' prospect Cooper Hjerpe, but with higher velocity, deadlier stuff, and a guy who could be on the fast track to the Major Leagues.
Smith went 8-2 during his sophomore season, posting a 3.64 ERA with 109 SO in 71.2 innings pitched. Smith struck out 9 batters through 3.2 innings against one of the nation's best lineups in LSU last year. This dude can pitch.
Another guy with an upper-90s fastball, while Smith doesn't hit triple-digits like Burns or Brecht, his slider could end up being a plus-plus pitch, something that could end up giving him the edge on other names on this list.
Like Burn, Brecht, and Caminiti, continuing to refine his other pitches (he uses a changeup as well) and working on his command will go a long way toward increasing his stock as a prospect.
