Temperatures in Arlington are expected to be over 100 degrees each day during the set with highs near 105 degrees for the 3:05 p.m. ET finale on Sunday.
"We actually talked about it a little on the plane," Francona said. "We don't want it to become an excuse. That's silly. It's great baseball weather. As the same time, we're not in it every day."
Francona insisted that the club's approach won't change despite the warm weather.
"The relievers will go out and do their routine, sit out there for a little bit and come in," Francona said. "The position players come in anyway.
"Do you know what you're going to see? You're going to see more balls during batting practice sitting in the outfield a little longer -- because we'll have a few less bodies."
Catcher Jarrod Saltalamacchia, who was with the Rangers before being traded to the Red Sox at the Trade Deadline, wasn't concerned about the heat either.
"There were a couple of questions about the heat here," Saltalamacchia said. "I think it's one of those things where if you play here all the time you get used to it. Teams from the West Coast come over here and it's a little tough. But I think we'll be OK."
