Tyson Ross entered Friday at 2-1 with a 3.50 ERA.
Padres starter Tyler Ross lost his no-hitter in the eighth inning against the Diamondbacks Friday.
San Diego held a 1-0 lead over Arizona thanks to a Franchy Cordero home run in the top of the fourth inning entering the eighth.
Ross has 10 strikeouts and gave up three walks while throwing 127 pitches in the outing.
He was in danger in the eighth when he walked Nick Ahmed to leadoff the inning, and then Ahmed made his way to third thanks to a wild pitch and a steal with one out. But Ross was able to get Deven Marrero to hit a grounder to second baseman Carlos Asuaje, who threw Ahmed out at the plate.
The next batter was pinch-hitter Christian Walker, who hit an RBI-double to chase Ross out of the game and tie it up.
Entering Friday, Ross had a 2-1 record and 3.50 ERA with 14 strikeouts through three starts.
In 2014, when Ross made the All-Star Game with the Padres, he tossed his first two career complete games, and his lone complete-game shutout. He threw one more complete game the following season.
The Padres are the only team in MLB yet to throw a no-hitter in its franchise history.
