The Rays recalled Scholtens from Triple-A Durham on Thursday.
Scholtens owns a 3.82 ERA and 1.27 WHIP through 37.2 frames in the majors this year but has fired 10.2 consecutive shutout innings at Triple-A. He'll return to the big leagues presumably to make a spot start during the Rays' upcoming series against Baltimore. Michael Grove was optioned to Durham in a corresponding move.
