Hunter has allowed left-handers to hit .293 (215-for-734) during his five seasons in the Major Leagues. That high average prompted Toronto manager John Farrell to switch things up.
Eric Thames and Colby Rasmus each moved up one spot in the lineup to hit sixth and eighth, while third baseman Brett Lawrie and catcher J.P. Arencibia dropped one slot.
"It was to get Eric a little higher up in the order," Farrell said. "Wanted to get a few more lefties the higher up that we could and without stacking them.
"Over the course of Hunter's career, left-handers have had decent success and with their bullpen predominantly right-handed, didn't want to stack right-handers too much."
The Blue Jays entered Friday's game against Baltimore hitting just .202 (46-for-228) on the season, which ranked 12th in the Major Leagues. The one saving grace has been their ability to hit with runners in scoring position as their .363 (17-for-47) ranks first in the Majors.
