LAWRENCEVILLE -- Cory Gearrin has been nearly flawless this season whether he was pitching for Gwinnett or Atlanta.
Wednesday's appearance for the G-Braves, though, was one the side-arming reliever would like to forget.
Gearrin didn't retire any of the seven Pawtucket batters he faced and the Red Sox scored five times in the ninth inning for a 9-4 victory at Coolray Field.
"It's a tough way to lose, especially with Gearrin on the mound," Gwinnett manager Dave Brundage said.
The G-Braves closer came in with a 1.34 ERA over 37 appearances in Class AAA and an even-better 0.79 mark for 12 major league games with Atlanta.
Against Pawtucket, though, he couldn't get a single out.
"They hit them where we weren't," Brundage said. "Everything fell in."
Gearrin allowed five singles, none of the balls hit hard, and walked two.
"He's been lights out all year," Brundage said. "One outing is not going to change my mind with that. He been as good as I've seen him lately. They just had his number this time."
Pawtucket, which is fighting for the wild-card spot in the International League playoffs, finished with 15 hits and the G-Braves had 11.
Ivan DeJesus had four hits for the Red Sox (75-63) and Tony Taylor drove in three runs with a triple and a homer. Jose Constanza, who leads the IL batting race with a .317 average, and Lyle Overbay both had three hits for Gwinnett (61-77).
Overbay came in just 3-for-16 in his first five games with the G-Braves, but had two singles and an RBI double to raise his average from .188 to .286.
Atlanta is counting on Overbay as a left-handed bat off the bench in September. The veteran first baseman was signed last week after being released by Arizona nearly a month ago.
Overday hit .292 for the Diamondbacks, but had just 18 at-bats in July.
"He's getting the rust off and swinging the bat like everyone knows he can," Brundage said. "He's been a nice addition for us and a real good addition for the organization."
Sean Gilmartin -- Atlanta's first-round draft pick last year -- made his sixth start for Gwinnett after being promoted from Class AA and allowed three runs on eight hits in 4 innings.
Veteran reliever Peter Moylan got out of the fifth with a double play, but allowed the tying run in the sixth.
The G-Braves are 36-36 at home this season and need a sweep of today's 5:05 p.m. doubleheader to finish with a winning record at Coolray Field. Julio Teheran and Randall Delgado are scheduled to pitch.
