Mets placed OF Scott Hairston on the 15-day disabled list, retroactive to August 24, with a strained oblique. Hairston will undergo an MRI soon, at which point the Mets will have a better idea when he might return, but the possibility exits that he could be out for the year. He's batting .235/.303/.470 with seven homers and a .773 OPS over 145 plate appearances this season.
