"Derek is certainly proving not only to us but to himself that he can be consistent," Washington said, "That's something that he thought about over the winter, to be prepared to do just that. It's nice to see him out there using all his pitches and throwing them for strikes. His breaking ball has much more depth and he has brought his breaking ball back into play. For the first few years, it was his bread and butter and he got away from it. He's not leaving his fastball over, he's putting it where he wants to.
"He's competing and he's executing his pitches a lot better. I'm not going to say he won't leave some over the plate or hang a breaking ball. But he's able to execute and commit. He's much better to me. He's a more polished pitcher than he was when was 16. His stuff is consistent and has been consistent since Day 1 of Spring Training."
