The Rays recalled Roycroft from Triple-A Durham on Wednesday.
Tampa Bay optioned Roycroft to Triple-A on Saturday, but he'll be eligible to rejoin the big club just four days later after reliever Cole Sulser (back) was placed on the 15-day injured list in a corresponding move. Roycroft is likely to be deployed in lower-leverage spots out of the bullpen while he's up with Tampa Bay.
