Locke shut down again

Jeff Locke’s MRI Thursday did not reveal any structural damage, Mattingly said, but the Marlins remain cautious with the left-handed pitcher.

He will not throw a baseball for at least the next seven days.

Locke experienced discomfort after a bullpen session earlier this week, and the team — knowing there’s plenty of time between now and Opening Day — opted to have him back off his throwing program.

Mattingly called it “head of the bicep tendinitis.” The head of the bicep is in the shoulder.

“Tendinitis obviously is a little tricky,” Mattingly said.
