Vinnie Pestano is ready to fill in for injured closer Chris Perez. As for his drop in velocity, Pestano said it's only a state of mind.

Manager Terry Francona named Pestano the Indians' new closer when Perez was placed on the disabled list Monday with a sore right shoulder after a spectacular blown save Sunday in a 6-5 loss to Boston at Fenway Park.

Pestano has been Perez's set-up man for the past two years. The Indians felt he was capable of succeeding Perez in the closer's role, but Pestano is not at his best right now. A sore right elbow forced him onto the disabled list earlier this month and his velocity has been down since he was activated on May 16.

"The whole radar gun thing, that can't be a factor in anything I need to do when I'm out there trying to get outs," said Pestano. "If I'm throwing 87, it's going to be 87. If that's everything I have, so be it."

Pestano blew a 4-3 lead in the eighth inning Saturday in a 7-4 loss to Boston. He was consistently clocked at 87 to 88 mph, well below his normal velocity of 91 to 93 mph.

Pitching coach Mickey Callaway and bullpen coach Kevin Cash have been helping Pestano adjust his delivery.

"Vinnie is going to pitch innings when games are on the line," said Francona. "Whether it's the seventh, eighth or ninth, we've got to get them out.

"There are some things mechanically [he's been working on]. In the near future, I think you'll see him be just fine."

Francona could have gone with Joe Smith or Cody Allen in the closer's role.

"Vinnie is comfortable slotting into that inning," he said. "Part of the reason for doing that is it makes it so much easier for us if you have an end point to get to because we have plenty of depth."

Pestano has closed in college and the minors.

"I'm very comfortable with it," he said. "I don't want to sound overly confident, but I've closed a lot in the past. . . . I do feel confident that I can fill in until CP gets back."
