Musgrove (shoulder) threw a bullpen session Sunday without issues, Adam Berry of MLB.com reports.
Musgrove suffered a minor shoulder injury (described as "shoulder discomfort") earlier in February. He was delayed to start camp but seems to be recovering fine, and he'll throw again Tuesday. Keep an eye on his progress once he's able to appear in Grapefruit League games, as that should help clarify his chances of being ready for the start of the season.
