The Braves have acquired veteran right-handed reliever Luis Ayala from the Orioles in exchange for Minor League pitcher Chris Jones. Ayala posted a 2.40 ERA while combining for 118 appearances with the Yankees and Orioles over the past two seasons. The 35-year-old right-hander allowed two earned runs and four hits in the only two innings he completed for the Orioles this year. With some uncertainty surrounding Jonny Venters, who is on the disabled list with a sprained left elbow, the Braves could use some depth in their bullpen. Eric O’Flaherty and Jordan Walden are currently serving as the primary setup men for closer Craig Kimbrel. Although he is right-handed, Walden has been more effective against left-handed hitters throughout his career. He has allowed hits in two of the four at-bats right-handed hitters have compiled against him this year. But he has limited left-handed hitters to a .203 batting average and .292 on-base percentage in his career. Ayala has allowed four hits in six at-bats against right-handed hitters this year. Last year, right-handed hitters batted .262 against him and left-handed hitters compiled a 2.84 batting average. Jones posted a 3.90 ERA in 45 relief appearances for Double-A Mississippi last year. The 24-year-old left-hander was acquired from the Indians in exchange for Derek Lowe after the 2011 season.
