A relief pitcher's most important work comes with his first 15 pitches. He lives or dies on the ability to make outs quickly, retire the leadoff man, and not allow runs to cross the plate early in his outing.
On pitches 1-15, here are Brandon Claussen's numbers:
NAME G IP H ER R HR BB SO K/9 WHIP ERA
Claussen 11 9.2 8 9 9 0 1 6 5.59 0.93 8.38
8 Hits, 1 BB -- 9 ER. That's actually pretty staggering, IMO.
