KANSAS CITY -- It appeared the Braves might be in trouble when Eric O'Flaherty and Jonny Venters both underwent Tommy John elbow reconstruction surgery in May. Within a span of a few days, the club lost its top setup man in O'Flaherty and any remaining hope that Venters might get healthy in time to at least provide bullpen depth during the season's second half.
But the Braves entered Wednesday's series finale against the Royals having compiled a 2.71 ERA in the 37 games they had played since losing O'Flaherty. The Blue Jays and Brewers were the only two Major League teams that compiled a better ERA during a stretch dating to May 18.
Still, the Braves are expected to attempt to land at least one veteran reliever before next month's Non-waiver Trade Deadline. While Jordan Walden and Luis Avilan have proven to be reliable as closer Craig Kimbrel's primary setup men, the Braves would like to add an experienced pitcher who could lessen the strain placed on Walden and Avilan down the stretch.
Avilan and Walden combined for three scoreless innings in the Braves 4-3 loss in 10 innings to the Royals on Wednesday.
The Braves are among the many teams expected to show interest in Cubs closer Kevin Gregg, who owns a 1.11 ERA in 25 appearances. Atlanta manager Fredi Gonzalez utilized Gregg as his closer while they were together with the Marlins in 2007 and '08.
Braves general manager Frank Wren surprised many this past offseason when he was able to acquire a pitcher of Walden's caliber in exchange for Tommy Hanson, who was likely going to be non-tendered if he had not been dealt to the Angels. But it is safe to say, Walden has proven to be even better than expected.
Walden missed most of Spring Training with a sore back and was sidelined for two weeks in May because of right shoulder inflammation. But in the 11 appearances he has made since returning from the disabled list, the former Angels closer has worked 11 1/3 scoreless innings and limited opponents to a .079 on-base percentage.
In his past 15 appearances entering Wednesday, Avilan logged 12 2/3 scoreless innings and limited opponents to a .143 on-base percentage.
While Avilan and Walden have provided indication they are capable of handling the setup duties, the remainder of the bullpen is made up of inexperienced relievers. Adding at least one more veteran arm would at least provide the Braves some more certainty during the middle innings.
