Legumina (ankle) was activated the 15-day injured list Sunday.
Legumina will return to the major-league roster for the first time since he was placed on the IL on May 14 with a right ankle contusion. The right-hander appeared in two games with Triple-A Louisville on his rehab assignment, allowing a solo homer while striking out four batters over two innings. Legumina will replace Kevin Herget in the big-league bullpen after Herget was optioned to Louisville on Sunday.
