Igarashi surrendered a pair of runs on four hits and two walks in one inning of work. He was also forced to throw 41 pitches, and didn't have the type of typical command that made him the most valuable reliever on Triple-A Las Vegas' roster this season.
"Pitches up in the strike zone," Blue Jays manager John Farrell said. "He had plenty of power to his stuff, but fastballs found their way over the middle of the plate. Whether it was a check swing by [Yorvit] Torrealba for a base hit or a walk mixed in -- 41 pitches to get through the inning, that's a long one."
The 32-year-old Igarashi posted a 1.29 ERA in 21 innings with Las Vegas, while striking out 28 and walking just three. He posted similar numbers last year in the Mets' farm system but has yet to see that success translate to the Major League level.
Igarashi has a 5.91 ERA in 70 career innings in the Major Leagues with the Mets and Blue Jays.
