Whitlock (1-1) recorded the loss Thursday, allowing an unearned run on four hits and two walks while striking out two over three innings in a 1-0 loss to the Blue Jays.
The loss can't be blamed on Whitlock, as the game's only run came thanks to an error by Christian Arroyo that allowed Lourdes Gurriel to reach base. His subsequent walk to Raimel Tapia moved Gurriel into scoring position. and Kirk's two-out single brought in the run. The right-hander earned the spot start due to Tanner Houck's vaccination status, which prohibits him from playing in Canada, but Whitlock will likely continue to be deployed in a variety of high-leverage situations all season.
