Perfect 10: Guerra thriving as Dodgers' closer

PHOENIX -- Javy Guerra on Friday night converted his first four-out save.

First ever, at any level.

Having inherited the Dodgers' closer role from the injured Jonathan Broxton, Guerra is a perfect 10-for-10 in save opportunities, the first Dodger to do that since Takashi Saito went 12-for-12, with a 1.69 ERA, in 2006.

Guerra has convinced manager Don Mattingly he's the real deal, even if he's not doing it in the heat of a pennant race.

"These are still big situations," Mattingly said. "I don't care if it's a race or not, it's still a tough situation. Watch the way he's reacted, his demeanor. I don't think he goes out there saying, 'We're 13 back, it doesn't matter.' Other than the San Diego game where the bases were loaded, most of his are non-top-steppers."

Guerra came up from Double-A Chattanooga to make his Major League debut May 15 and now he's getting four-out saves, as he did Friday night, which included three strikeouts.

"Mentally, you just have to prepare for it and try to treat the eighth-inning at-bats like they're the ninth," he said. "I watched 'Brox' do it a lot. I never did it in the Minor Leagues, but it's kind of different in the Major Leagues. There's obviously more on the line. Even though this was the first time for me, I just went at it like I had to get an out."
