The Rays announced on Monday that third baseman Evan Longoria will be activated from the 60-day disabled list prior to Tuesday's series opener against the Blue Jays.
To make room on the active roster, infielder Will Rhymes was optioned to Triple-A Durham.
Longoria should provide a significant offensive boost for the Rays, who have been shut out over their last 21 innings.
Out since April 30 with a partially torn left hamstring, Longoria previously attempted a rehab assignment in June, but a setback sidelined him again. He started his second stint with Durham on July 26 and appeared in eight games, all as a designated hitter.
Longoria struggled at the plate, going 5-for-25 with seven walks and eight strikeouts, but tallied two hits on Sunday.
Manager Joe Maddon previously said that he will continue to use Longoria as a DH until the hamstring is fully healed. Maddon is concerned about overworking Longoria and does not expect him to play every day when he first comes back. In 23 games prior to the injury, Longoria was batting .329 with four homers and 19 RBIs. The team went 15-8 in those games but is 41-44 since.
