"The one thing I don't ever want to do is kind of have 'the flavor of the week,'" Francona said. "I think that can put your bullpen in turmoil. So unless there really needs to be a move made, I try to stay somewhat consistent."
A centerpiece of the Indians' rotation has been Dan Otero, who has allowed just one earned run over nine appearances in June.
"Otero's been really big for us, because we've used him everywhere, and he's gotten outs. Everybody has different styles. So it's worked pretty well.
Francona said he likes to talk with his relievers a lot and remain transparent with them.
"They know we're going to pitch who we think would be best," he said, "and sometimes it might be early in the game, if the game's going to swing early, we don't want to wait around."
The bullpen's recent success has been a good complement to a starting rotation that has registered a Major League-low ERA (2.63) in the month of June.
