Boxberger (back) doesn't seem to have any concern about his availability for Opening Day, Marc Topkin of the Tampa Bay Times reports. "I'll definitely be ready April 2," Boxberger said.

The right-hander is feeling better after tweaking a lat muscle in a workout last week, and is set to toss a bullpen session Monday to test things out. He'll likely need to complete multiple sessions and face hitters in batting practice or a simulated game before he's cleared to make his Grapefruit League debut, perhaps at some point next week.
