Yuki Saito started today's game against the Softbank Hawks but was removed after only an inning (retired the side in order on 10 pitches) due to discomfort in his left flank.
UPDATE 9:30pm - The Fighters are planning on taking Saito off the active roster tomorrow. They'll decide on what to do next after he gets checked out at a hospital.
Saito's comment on the pain: "It isn't like there's a sharp pain. It's just a discomfort. I think I'll be ok."
