Jerry Hairston, Jr. is upset at sitting in favor of Neifi Perez, reports the Chicago Tribune.

The Trib quotes Hairston as saying, "I'm not [peeved]. I just want to play every day. It's no different from yesterday. … I don't have to prove myself to anybody. What I've done when I'm healthy speaks for itself. . . . I'm a positive person. I don't feel I'm arrogant or cocky. Neifi is a good player. I'm happy for him. I'm definitely pulling for him."

1:20pm CT. Mark Prior v. Jake Peavy.

ICubs still can't win, and Scott Moore stays hot.

"Iowa Cubs shortstop Nate Frese will return to Des Moines today to undergo tests after fainting in the dugout during Saturday night's Pacific Coast League game at Albuquerque," reports the Des Moines Register. "Frese . . . was rushed to a hospital, then released. He watched Sunday's game from the dugout - with a headache."
