New York minor league OF Slade Heathcott underwent an MRI for a sprained right thumb, the result of an outfield collision Thursday with Ronnier Mustelier.
New York third baseman Ronnier Mustelier left in the fourth with bruises on both legs after running into a railing near the stands on Juan Pierre's foul ball.
But minor leaguers Ronnier Mustelier and Melky Mesa are right there with that group, with Mustelier challenging Johnson in the infield and Mesa competing hard to push Francisco aside in the outfield.
