The Rays reinstated Sulser (back) from the injured list Friday.
Out since late July with lower-back spasms, Sulser began a rehab assignment at Triple-A Durham on Aug. 19 and has since given up two earned runs on nine hits and four walks while striking out seven batters over seven innings. Now fully healthy, he'll reclaim a middle-relief role in Tampa Bay's bullpen and replace Manuel Rodriguez (back) on the active roster.
