The Mets should know the results of that test by Wednesday evening, after Beato left Tuesday's game due to muscle stiffness. Even if he were healthy, Beato would be on the bubble of a bullpen competition that has as many as 10 competitors vying for two open spots.
One of Beato's main challengers on that front, Bobby Parnell, bounced back from two rough outings over the weekend to pitch a perfect inning Wednesday.
"Bobby Parnell wants to make this team in the worst way," manager Terry Collins said. "One of the things I saw [Wednesday] was great command."
