ATLANTA -- Braves general manager Frank Wren wasn't ready to confirm that there was an agreement reached with George Sherrill on Wednesday.

But he provided every indication that he's aggressively moving toward making Sherrill the left-handed specialist he has been looking for to add to his bullpen.

While posting a 6.69 ERA in 65 appearances with the Dodgers this season, Sherrill limited left-handed hitters to a .192 batting average (14-for-73) and a .286 on-base percentage. Right-handed hitters tagged him for a .427 batting average and a .516 on-base percentage.

"He's a very effective guy against lefties," Wren said. "We also felt like he made great strides in the second half of [the 2010 season]."

With Jonny Venters set to serve as the primary setup man and occasional closer, the Braves will use Sherrill and Eric O'Flaherty as their primary left-handed specialists in the middle innings.

"He's got the good breaking ball," Wren said. "He's one of those guys that goes right after them. He knows how to get guys out."

Sherrill earned All-Star status on the way to notching a career-high 31 saves with the Orioles in 2008, and posted a 1.70 ERA in 72 appearances combined with the Orioles and Dodgers in '09.
