I can trust Shreve, Smith, Lugo, Ottavino, May, and Diaz. Williams, Reid-Foley, and Rodriguez (the guy they got for Miguel Castro) have stunk it up. I was shocked they traded Castro- he had a great spring training and he has potential.
As for Ottavino, he's seen better days and walks way too many batters. Don't trust him in a big spot, he will implode.
