Top Braves prospect Julio Teheran struck out six over six innings and Todd Redmond followed up with six strong frames of his own as Triple-A Gwinnett took a doubleheader from Lehigh Valley, 6-3 and 7-0, on Tuesday afternoon.

Teheran (4-0), in his first start since returning from Atlanta, struck out six and held the IronPigs to an unearned run on six hits and two walks. He threw 101 pitches -- 78 for strikes -- and lowered his ERA to 1.65 in his seventh start.

Rehabbing Phillies reliever Jose Contreras started for Lehigh Valley and reportedly told the club he was ready to return to the Majors following his two scoreless innings.

Teheran, who made two spot starts for Atlanta, has fanned six or more batters in all of his last four starts with Gwinnett. He struck out the side in the first and induced a double play from Cory Sullivan to escape a bases-loaded jam in the second inning.

The righty walked Rich Thompson to start the third, but picked him off. Lehigh Valley, pesky all afternoon although unable to convert, scratched across a run in the fifth when Brian Bocock reached on a fielding error by right fielder Stefan Gartrell and Brandon Moss followed with a pinch-hit RBI single up the middle. Teheran worked around a single and a walk in the sixth before reaching his pitch count.

Redmond (3-4), the reigning International League Pitcher of the Week, was just as good -- he struck out seven and allowed two hits over six scoreless frames. The righty threw 54 of his 79 pitches for strikes before Anthony Varvaro worked a perfect seventh to close out the win.

Former Southern League All-Star Gartrell knocked in four runs in the first game, while Mauro Gomez and Jeff Fiorentino each went deep for the Braves in the second contest.
