"Sue [Falsone, our trainer], thinks it will be a day, but we'll see," Mattingly said. "He was getting [Sunday] off anyway with the [pitching] matchups, so the only thing is, can he pinch-hit? We're not thinking DL at all. He said he felt it in Chicago [in May] and it went to the hammy."
Hairston went on the DL then with a hamstring strain, but has played semi-regularly since returning on May 25.
Hairston said he felt the area tighten while taking a first step to his right on Donovan Solano's fifth-inning double that triggered a four-run rally for the Marlins.
Mattingly started Luis Cruz at third base on Sunday.
