Lopez was recalled from Triple-A Durham and is expected start or work in bulk relief Sunday in Toronto, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

The 25-year-old made his MLB debut in August and pitched well in three outings for the Rays with one earned run allowed and a 4:0 K:BB across seven innings, and he'll receive another look with the big club in the regular season finale. Lopez was also effective at Triple-A Durham this year with a 2.72 ERA, 1.33 WHIP and 87:47 K:BB in 18 starts after opening the campaign with Double-A Montgomery.

Lopez was optioned to Triple-A Durham on Thursday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Lopez was terrific during his short stint with the Rays, allowing just one run over seven relief innings. He was needed for three frames in Wednesday's win, though, so Tampa Bay is swapping him out for a fresh arm.

Lopez earned a save in Monday's 10-2 win over the Giants, allowing one run on three hits while striking out two batters over three innings.

EDGE Analysis

Lopez was called up from Triple-A Durham earlier in the day and made his first big-league appearance in the bottom of the seventh inning with Tampa Bay holding a 6-1 lead. The southpaw encountered a bases-loaded situation due to an error, single and hit-by-pitch but showed poise in striking out Wade Meckler to end the threat. Lopez then allowed a run in the eighth before retiring the side in order in the ninth to earn the save. He threw 47 pitches in the outing, so he may be out of commission for a few days or sent back down to the minors in favor of a fresh arm.
