Gearrin pitched in 10 games since July 31, when he was called up for the second time this year. He didn't allow a run and struck out nine batters in 8 2/3 innings.
Manager Fredi Gonzalez said he liked what he saw from Gearrin in his most recent stint in the Major Leagues. While Gonzalez didn't make Gearrin any promises, the right-hander will likely be back in the Braves' bullpen after rosters expand on Sept. 1.
"Gearrin's done a good job when he's been up here," Gonzalez said. "I think we'll see him again."
