But catcher Russell Martin said it was also a product of sign stealing.
Martin said that the Blue Jays were essentially stealing signs from the get-go, which might have helped them build a big lead with an eight-run first inning.
"You move your head one way it's a fastball, you move your head the other way it's a slider," Martin said. "It was pretty blatant."
Martin didn't pick up on it enough to change the signs until the fourth inning, when Jose Bautista was on second base. When he did switch his signals, second baseman Aaron Hill struck out on a curveball in the dirt by Hector Noesi.
But Martin didn't have any problem with them trying to pick up his signs and relay them.
"It's up to us to catch it and change the signs," he said. "I'm not blaming them for anything. ... It's one of those things you don't really talk about, but it's part of baseball. It's always been."
The eight runs the Blue Jays scored were a season high for any frame and tied the franchise record for the first. During Thursday's win, every member of their starting lineup had at least one hit and one run scored.
"It's just an easier game when you know what's coming," Martin said.
