In conjunction with third baseman Brett Lawrie being placed on the 15-day disabled list Wednesday with a left ankle sprain, the Blue Jays recalled right-hander Todd Redmond from Buffalo and selected the contracts of right-hander Neil Wagner and left-hander Juan Perez from the same club.
Ortiz, who threw three innings of relief on Tuesday, was 1-2 with a 5.01 ERA in six appearances -- including three starts -- with the Blue Jays
The right-handed Weber pitched in his third straight game Tuesday, surrendering the game-winning solo home run to Braves designated hitter Brian McCann. In three innings with Toronto, he allowed just that one earned run and struck out two.
Redmond, 28, has made two appearances this season for Buffalo, including one start, posting a 1-0 record with a 9.53 ERA. He began the season on the Minor League disabled list with right shoulder impingement. He is 72-61 record and a 3.60 ERA in 209 games over nine Minor League seasons. He was claimed on waivers from Baltimore on March 22.
Perez, 34, posted a 0.86 ERA in 17 relief appearances for Buffalo. He has appeared in 42 Major League games, going 1-2 with an ERA of 4.88 in four seasons for the Pirates, Phillies and Brewers.
Wagner, 29, has appeared in 19 games for the Bisons, recording 13 saves and 0.89 ERA while allowing just 10 hits and striking out 32 in 20 1/3 innings. He has appeared in six Major League games, all in relief for the A's. in 2011.
"We're going to need probably a couple of pitchers with [Esmil] Rogers going tomorrow in a spot start," Blue Jays manager John Gibbons said. "We really don't know what's going to happen there."
