Teheran went 5 2/3 scoreless innings in only his second start for the M-Braves and Tyrelle Harris wrapped up the final 3 1/3 frames in his team debut as the duo combined for just the second no-hitter in franchise history, a 2-0 victory over the BayBears.
Teheran (1-1) walked three and struck out seven before reaching his 95-pitch limit with two outs in the sixth inning, and Harris allowed just one baserunner -- a walk in the eighth.
Speaking through a translator, Teheran said he had all of his pitches working during the outing.
"I am feeling really excited right now," said the 19-year-old from Cartagena, Colombia.
"I wasn't locating my pitches very well last time, and I was trying too hard and making too many mistakes," he added. "But tonight I was using my fastball well, and I threw a couple of good changeups. I was just trying to locate my fastball and make sure that I threw it for strikes."
Teheran wasn't sure just how much he was going to have to rely his fastball in the Southern League. He said so far he has relied on it much more than his offspeed stuff, in particular his curveball and screwball.
He added that the key has been being able to locate any of his pitches in any count and continue to put up zeros.
Even though Teheran felt good enough to stay out on the mound, he understood about having to exit when he reached his pitch count.
"I had reached my max," he said. "I was so focused on throwing the baseball that I didn't know what the pitch count was. I just knew that I was feeling very good and that I could have gone further."
In fact, Teheran was so focused that he did not realize he was throwing a no-hitter until after he had left the ballgame.
"I had never even thought about the no-hitter," he said. "I was just thinking about working on the mound and getting outs."
Teheran, who pitched a scoreless inning for the World team in last month's XM Futures Game, also appears unfazed by the hype that regards him as one of the best arms in the Minor Leagues.
"I don't think about it at all," he said. "I am focused on what I am doing and things have been going great. I just want to keep working hard like I have been."
Once Teheran had left the game, it was California native Harris' turn in the spotlight.
The reliever arrived in Mississippi on Sunday after being promoted from Myrtle Beach, where he was 1-2 with a 3.71 ERA in 17 appearances.
He retired the first five batters he faced before allowing a one-out walk to pinch-hitter Cyle Hankerd. After striking out Evan Frey, Ollie Linton lined a ball that first baseman Mauro Gomez knocked down.
Gomez was charged with a fielding error on the play, but Harris fanned Collin Cowgill to end the frame. It was the closest the visitors had come to a hit since Cody Johnson snared Cowgill's sinking liner in the sixth.
Harris struck out the side in order in the ninth to pick up his second save of the year and complete the no-no.
Tommy Hanson tossed the first no-hitter in M-Braves history on June 25, 2008.
