The Gwinnett Braves lead the International League with a 2.99 ERA and 20-year-old Julio Teheran ranks second on the circuit with a 1.78 mark of his own.
Those credentials were bolstered in a pitchers' duel Tuesday night as Teheran fired seven three-hit frames in the G-Braves' 4-0 blanking of the Indianapolis Indians at Victory Field.
Teheran did not figure in the decision after striking out three without walking a batter. After yielding a run to Buffalo in the first inning of his June 4 start, he has tossed 20 scoreless frames. During that streak, he's allowed nine hits and struck out 19 without issuing a walk.
Teheran, MLB.com's preseason No. 10 prospect, retired the first six Indians before yielding a leadoff double to Gorkys Hernandez in the third inning. The Colombian-born right-hander promptly picked off Hernandez, then retired nine more in a row before Corey Wimberley singled with one out in the sixth. Teheran also picked him off and finished his seven frames having faced one over the minimum after Brian Friday collected Indianapolis' third hit in the seventh.
The 20-year-old threw strikes on 60 of 88 pitches, his lowest total since his second start of the season on April 14.
Indianapolis starter Garrett Olson also was cruising. The 27-year-old left-hander tossed five hitless frames, marred only by a one-out walk to Major League veteran Julio Lugo in the first. The former first-round pick was making his third start of the season after working out of the bullpen for both the Indians and Pirates. He fanned five and also faced just one over the minimum, throwing 44 of 66 pitches for strikes.
Indianapolis reliever Chris Leroux pitched a perfect sixth and Justin Thomas got two quick outs in the seventh before Braves first baseman Mauro Gomez broke up the no-hitter with a single to left. Michael Dubee, making his Triple-A season debut, tossed a 1-2-3 eighth inning but ran into trouble in the ninth.
With the game still scoreless -- Gwinnett had one hit, Indianapolis three -- Braves pinch-hitter Jose Constanza opened the ninth with a single back up the middle. Wilkin Ramirez moved him to second with a sacrifice and Lugo walked on four pitches.
Jeff Fiorentino, who replaced rehabbing slugger Jason Heyward, greeted Cesar Valdez by lashing an RBI double to right. After Gomez was intentionally walked, Stefan Gartrell cleared the bases with another double.
Dubee (0-1) was charged with two runs on a hit and a walk over 1 1/3 innings.
Juan Abreu improved to 4-0 after pitching a hitless eighth. Anthony Varvaro gave up a single -- the Indians' fourth hit -- in the ninth.
Heyward went 0-for-3 in the second game of his rehab stint. During batting practice, he hit a ball over the right-field fence and became the first player to strike the structure that houses the Victory Bell, the Indianapolis Star reported. The bell was installed before the season.
The G-Braves, who also blanked the Indians on Monday, rank second in the IL with five shutouts. They went 6-2 on an eight-game road trip and are tied with the Durham Bulls for first place in the South Division.
