Single-A Charleston activated de Brun (wrist) from the 60-day injured list Tuesday.
After recovering from December wrist surgery, de Brun completed a two-week rehab assignment with the Rays' rookie-level Florida Complex League affiliate. The 19-year-old outfielder was part of Tampa Bay's compensation for trading Shane Baz to the Orioles last winter, and he's gone 10-for-22 (.455) with two doubles, four RBI, three stolen bases and six runs scored over his first seven career minor-league games.
