Pelfrey's problem has been command of his fork ball, which he lost after the first half. Before this season Pelfrey was basically a two-pitch guy that struggled after the second time through the order. His fastball is his bread and butter, bending left and right low in the zone. Unfortunately, after seeing it a couple times, hitters barrel it up and start driving it. Pelf's benders are at best average, and he doesn't throw them well enough to strike out a lot of guys. Enter the fork ball, Pelfrey's third and most difficult pitch to hit and throw. When he had command of the fork, Pelf could dangle it belt to ankle, getting lots of whiffs. Now without it, he's back to being a two-pitch guy. Frankly, that's bull pen stuff. This might be a very good time to give a starter tryout to Logan Darnell. Maybe he's better than we realized, like Tyler Duffey. Why not find out.
