Scott Hairston (shin) may be available to pinch-hit Tuesday night against the Cardinals. Hairston suffered a left shin contusion when he fouled a ball off his leg in the first inning Monday night. "It's the top of his foot, where the shin meets the foot," said Mets manager Terry Collins. "It's that meat part in there that's swelled up pretty good. He told me he could probably pinch-hit. Hopefully if he gets on he could continue to run." Consider him day-to-day right now.
