"I felt better coming into today's game, and I wanted to go full throttle from the very first inning, and I hope I can have more outings like this in the future," said Ryu.
Ryu attacked right-handed hitters with cut fastballs instead of his preferred changeups. In his only other start this season, Ryu was chased after walking five in 3 2/3 innings vs. the D-backs, a game the Dodgers lost in 15 innings, 8-7.
"I had a pretty bad outing in my first start, so going into today's game, I wanted to do well," he said. "But I think it was more about my approach today. I used to rely more on the changeup, but tonight I utilized more of the pitches I had."
Former Dodgers Draft pick Stephen Piscotty broke up Ryu's no-hit bid with two outs in the top of the fifth inning with a grounder up the middle and out of the reach of shortstop Corey Seager.
Ryu, who walked in the second and singled in the fourth for his first hit of the season, was removed for a pinch-hitter in the sixth after making 90 pitches.
"Hyun-Jin was as good as it gets for me," said manager Dave Roberts. "Tonight, he was really focused. He got the swing and miss when he needed to. He was in control all night. Even his first start, I thought he was just missing. Tonight, he was more on point and getting those close calls and had the conviction pitching against right-handers. That's something that, for him and the rest of the staff, hopefully builds momentum."
Ryu was pitching on extra rest because of a scheduling quirk and a rainout that left the Dodgers with four days off in an eight-day span.
"He was mixing and really didn't give you a fastball in a fastball count," said A's catcher Jonathan Lucroy. "His cutter was really good. He can backdoor it, he can throw it in on righties, and he kept it down. Whenever it's down like that, it's really hard to square up."
