The Padres' No. 9 prospect allowed one hit and struck out seven over five innings as Class A Short-Season Eugene beat Spokane, 5-4, in 10 innings on Tuesday.
Ross, who did not figure into the decision, faced one over the minimum for the Emeralds. He walked two and received some help from his defense, which turned two double plays behind him.
"My fastball control was really good today and my slider was good, especially on lefties back doors," Ross said. "Changeup was good. I was just gripping it too tight, but I still felt comfortable throwing it."
A first-round selection by the Padres in 2011, Ross spent almost half of his first full season in pro baseball pitching in the Midwest League before heading to the Northwest League. The California native was 0-2 with a 6.26 ERA in six starts for Fort Wayne and learned some hard lessons that have served him well.
"I think that the biggest thing that I learned is the importance of working thirds of the plate," Ross said. "Even early in the count, trying to make fastball pitches on the corner and keeping the ball down. I'd say that when I left the ball up is when I got hit the hardest.
"It's definitely what I've been working on the most. It's what [manager] Pat Murphy emphasizes for me when I'm on the mound. So far it's paid off, as you can see tonight."
In eight starts for Eugene the 19-year-old right-hander is 0-2 with a 2.03 ERA. Ross, the brother of Oakland hurler Tyson, has fanned 28 batters in 26 2/3 innings for the Emeralds and has surrendered 16 hits while walking nine batters. He's trying to make up for lost time, having missed a month due to shoulder inflammation. Despite that, Ross deems his season a successful one.
"It's been a good year despite the injury, I could have done without that," he said. "I've learned a lot. Even with the injury, I'm happy with how it ended up. I'm happy with my performance on the mound overall. It was a great character-building year.
"I went down to Arizona to do rehab work and that was real good. It was tough to sit on the sidelines and watch, but at the same time, it motivated me to want to get healthy again and help the team win."
Corey Adamson hit a walk-off single in the bottom of the 10th to rally the Emeralds. Alberth Martinez tied the game two batters earlier with an RBI single. Edwin Moreno slugged a solo homer.
Matthew Shepherd (4-2) was credited with the win after allowing a run on hit in one inning of relief.
