Igarashi, who turned 33 Monday, allowed four earned runs in one inning over two appearances this season with the Blue Jays, who brought him up May 25 and designated him two days later.
He was 5-2 with a 5.74 ERA in 79 relief appearances with the Mets in 2010-11, spent spring training this year with Pittsburgh and was acquired by the Blue Jays on March 30. He was 1-1 with a 1.29 ERA and four saves at Triple-A Las Vegas.
“I don’t know a lot about him, but we expect him to be a reliever that can possibly contribute here for us,'' Joe Girardi said. "I don’t think they would have signed him if they didn’t think he could contribute.”
New York cleared a spot on the 40-man roster Tuesday by transferring right-hander Brad Meyers from the 15-day to the 60-day disabled list.
