Scott Hairston (oblique) is unlikely to return this season. After feeling discomfort while doing drills Thursday, Hairston tried to exercise on an elliptical machine Friday but had to step off after less than a minute. "I haven't had a pain-free day yet," Hairston said. "I've got to wait until that happens, but there's only so much time left." If he's indeed finished, he'll end the year with a .235/.303/.470 batting line with seven homers over 145 plate appearances this season.
