Hideki Okajima, RP
Fast fact: Opponents batted .061 (2 for 33) against him with two or more runners on base.
Lowdown: He could be the key to the success of the bullpen. Supposedly with a new pitch, Okajima comes in as a proven commodity, rather than an unknown Japanese lefty. But can he replicate his success? Fatigue was a factor in '07, with Okajima going from a 0.83 ERA in the first half to a 4.56 ERA in the second half (in 18 fewer innings).
