ATLANTA -- After Monday night's home-opening win over the Phillies, the Braves announced that they are sending Joey Devine back to Triple-A Richmond.
Replacing him on the roster will be Peter Moylan, the right-handed sidewinder who was noticed while pitching for Team Australia in the World Baseball Classic.
Devine struggled in the two appearances since being promoted from Richmond on Thursday. He's been bothered by a sore lower back that affects him each time he raises his leg during his delivery.
"I'm not throwing the ball good enough to be at this level," said Devine, who was the club's top draft pick last year. "I need to go down there, figure some things out, get some innings in and keep battling."
During Friday night's win over the Giants, Devine surrendered a two-run home run to Moises Alou. That simply continued the long ball struggles he incurred after making his Major League debut in August last year.
But things got worse on Saturday, when he threw just 19 of 42 pitches for strikes, issued four walks and uncorked three wild pitches. During the span of those two appearances, he recorded a total of three outs and allowed seven earned runs.
"I've got to get healthy first of all," Devine said. "Then second of all, I've got to go down there, pitch and get some confidence back."
Devine began feeling the discomfort in his back while pitching against the Yankees at Disney's Wide World of Sports complex on March 27. He visited a doctor on Monday and will get results of X-rays later this week.
Moylan hadn't played in the United States since 1997, when he was with the Twins at one of their rookie-level affiliates. He began throwing sidearm about seven months ago and a short time later found that his fastball was being clocked at 96 mph.
After throwing in the Classic, Moylan got a number of offers from various big-league organizations. The 27-year-old right-hander has allowed two earned runs, recorded four strikeouts and issued three walks in four innings with Richmond this year.
