The Braves have acquired right-hander Luis Ayala from the Orioles in exchange for minor league lefty Chris Jones, the Orioles announced (on Twitter).
As Roch Kubatko of MASNsports notes (on Twitter), the move allows the team to call up outfielder Chris Dickerson and makes it easier to keep Rule 5 pick T.J. McFarland on the 25-man roster.
Ayala, 35, returned to baseball in 2011 after not pitching in the Major Leagues in 2010. Since his comeback, he's reinvented himself, compiling a 2.50 ERA, 6.2 K/0 and 2.3 BB/9 in 133 innings of work. While he's not a left-handed reliever, Ayala gives Braves' manager Fredi Gonzalez another late-inning option with Jonny Venters currently on the shelf.
The 24-year-old Jones has a 3.58 ERA, 8.3 K/9 and 3.3 BB/9 in 356 2/3 minor league innings. He's yet to pitch higher than the Double-A level, where he's maintained his solid strikeout numbers but owns a 4.11 ERA. He will report to Double-A Bowie for the Orioles.
