The Braves claimed left-handed reliever Dustin Richardson off waivers from the Florida Marlins and have assigned him to Triple-A Gwinnett.
The Braves wanted some left-handed depth for their bullpen. Left-hander Eric O’Flaherty has struggled some with periodic back pain.
Richardson is a former fifth round draft choice of the Red Sox in 2006 and was traded to Florida this past offseason for left-hander Andrew Miller. The Marlins designated him for assignment last week to open a spot on their 40-man roster for Dewayne Wise.
Richardson went 3-1 with a 3.66 ERA in 23 relief appearances for the Marlins’ Triple-A affiliate New Orleans. Lefties were hitting .341 off him, with 15 hits in 10 2/3 innings, while he limited right-handers to a .208 average, with 16 hits in 21 1/3 innings.
Richardson was assigned to the Braves’ 40-man roster, which had an open spot.
