Igarashi, who turned 33 on Monday, spent Spring Training with the Pirates before being acquired by Toronto on March 30. He allowed four runs in two big league appearances spanning one inning for the Blue Jays, while also posting a 1.29 ERA and recording four saves in 21 innings for Triple-A Las Vegas.
Originally selected in the second round of the 1998 Nippon Professional Baseball Draft, Igarashi spent 10 seasons with the Tokyo Yakult Swallows of the Japanese Central League. In two seasons with the Mets (2010-11), Igarashi combined to go 5-2 with a 5.74 ERA in 79 relief appearances.
To make room on the 40-man roster, the Yankees transferred right-hander Brad Meyers -- out with a right labrum strain -- to the 60-day disabled list.
