Strickland is a legitimate pitching prospect. He's a dark horse, no doubt about that, but the guy is 20 years old in age appropriate competition and he's a big powerful kid (6'5" 200LBS) so the 93 he throws now is in a good position to go up. He also has excellent command, a useful component for a guy who also throws hard. He gets that fastball up into the mid 90's, with his command, he could get himself on the radar screen.
In short he's got good projectability and he's exactly the kind of pitcher you like to take in the lower rounds.
That said, he's someone else's problem now. I'm not sure why a Pirates prospect is showing up here.
