Well, as far as knapplc improving our pen, that remains to be seen. I've never seen him pitch
I actually think the pen will be tolerable this year. Villanueva's been fantastic in relief, Stetter looks like the real deal as a lefty specialist, and there are a number of interesting young arms (Tim Dillard, Omar Aguilar, Eduardo Morlan, RJ Swindle) that will get a shot. A healthy David Riske would make a big difference, injuries killed his season. He's a career 3.50 ERA guy who just derailed last year with elbow injuries. It's the rotation I'm worried about....they need to sign someone, whether it be Sheets, Looper, Perez, someone. I don't want to see Suppan/McClung penciled in 4/5 to start the season. McClung's an adequate spot starter/long reliever, but shouldn't be counted on for more than that.
