Sounds like he'll be OK. Just some "tightness" and he was smart not to bust out of the box on that play. With the Mets already up by 5 or 6 at the time, it was a smart move by him to hold back.
As a Mets fan who drafted Reyes 2nd overall, I'm praying to the baseball gods that he wakes up this morning feeling fine.
