Wagner made 20 appearances for the Blue Jays earlier this season and posted a 2-3 record and 3.26 ERA in his 19 1/3 innings. With an overworked relief corps, manager John Gibbons said it was only logical to go with an extra reliever instead of another position player to use off the bench.
"We've needed it for a while," Gibbons said of an eight-man bullpen. "We haven't had it lately, you don't want that, but sometimes you need it."
Toronto's bullpen entered play on Friday night having thrown the most innings (381) in the Major Leagues. Despite the heavy workload, the club's relievers own an impressive 3.17 ERA while striking out 355 and limiting opponents to a .228 batting average.
The timing of an extra arm couldn't have come at a better time. Right-hander Josh Johnson managed to record just seven outs during his start on Thursday night, and the result was even more stress on the bullpen. It will take at least a day or two for things to go back to normal, but Wagner will help ease the transition.
