Smyly, who hasn't pitched this season after being sidelined by left shoulder tendinitis during spring training, is scheduled to face Toronto on Friday night.
''I'm excited to get the season going for myself,'' Smyly said Wednesday. ''I'm ready. I'm just anxious to get out there.''
The Rays made a series of roster moves Wednesday.
Infielder Ryan Brett, who hurt his left shoulder diving back to first on a pick off play Tuesday night, was placed on the 15-day disabled list and infielder Jake Elmore had his contract purchased from Triple-A Durham.
To make room on the 40-man roster for Elmore, left-hander Jeff Beliveau was transferred from the 15- to 60-day DL.
Beliveau will have surgery Thursday to repair a torn left labrum.
