Rogers Centre closed its roof on Thursday afternoon because of a heat index that approached 48 degrees Celsius -- 118 Fahrenheit -- with humidity.
There were similar conditions at the Ballpark in Arlington on Friday, with temperatures in the afternoon hovering around 44 degrees Celsius -- 111 Fahrenheit -- with humidity.
"There's a number of things available to guys," Blue Jays manager John Farrell said. "Some are traditional as far as what we'll be able to have for every guy in the dugout. Those are no different when you get into the heat."
Prior to the series, Farrell talked about possibly having his starting pitchers take an IV before each game. That decision will ultimately be left to the individual, but the treatment is available for any player who is concerned about becoming dehydrated during the game.
"You don't want to strongly suggest to someone that they feel like they're doing something outside their normal routine," Farrell said.
"This is a matter of fluids. It's not a huge thing. But with every starter, they know their routine and they're going to hydrate extensively the day or two prior to their start, and I'm sure Jo-Jo [Reyes] has done that leading into today."
