I really think Shawn Hill is worth picking up now. He is showing that he can keep the ball on the ground (15 ground balls- 6 Fly ball outs last outing), and that will definatly pay divident in the black hole that is RFK.
Also, for all those people complaining about his WHIP, it currently stands at 1.07! And while he may not be a strikeout pitcher, he does have a 20-8 strikeout walk ratio.
It's still early in the season, but combine this April with Spring training and a couple of starts last year and you have a SERIOUS sleeper out there.
