Multiyear BPV's for Red Sox pitchers

Base Performance Value, a baseballhq.com stat, measures a pitchers' skill set based on K/9, BB/9 and GB%. Generally a starter should be above 50 for any shot at sustained success and a relief pitcher higher than that.

What I have done here is listed the BVP's for players who have pitched in consecutive seasons with the Red Sox to show which direction their skills are heading.

It's nice that Beckett's option vested for 2010 and we don't need to give him huge money this offseason. It will be interesting to see which direction he goes next year.

Lester's line speaks for itself, three consecutive jumps and is already elite.

Papelbon's 2009 was very concerning for a while, but now not so much. He talked about how he was working on some things and trying to keep his arm fresh, so we shall see. His K/BB did improve from 2.3 to 5.8 from the 1st half to the 2nd half.

Okajima, slipping... his arbitration years should be interesting.

Delcarmen was being viewed as a potential closer target for many teams heading into the 2009 season, but as you can see he was a complete disaster this year. He's still young and presumably there are no major arm issues, but the fall across the board is frightening.
