The Yankees' No. 5 prospect tossed five hitless innings in his second start of the season as the Class A Charleston RiverDogs defeated the Augusta GreenJackets, 11-5.
After fanning three over six scoreless frames in his first outing, the 19-year-old right-hander struck out eight and walked two on Wednesday.
"It feels very good," Campos said through a translator. "I've been working with our pitching coach, Danny Borrell, on my mechanics. I'm very happy with the outings I've had."
The only run off Campos came in the first after a pair of RiverDogs errors. Leadoff hitter Kelby Tomlinson reached on a fielding error by second baseman Angelo Gumbs, then came around to score two batters later when first baseman Reymond Nunez made a throwing error following a groundout.
"My mind was set to do my job and keep working," Campos said. "I know errors are going to happen, so I have to keep working hard and command my pitches and give the team a chance."
Campos allowed only two more baserunners over the rest of his outing, both on walks. Meanwhile, the Charleston offense lit up the GreenJackets, scoring nine runs for Campos and then adding two more after he left the game.
Yankees' No. 8 prospect Dante Bichette Jr. tripled in three runs and Tyler Austin added a triple, a double and two RBIs.
"[The offense gave me] confidence to attack hitters," Campos said. "I was more comfortable."
Augusta's first hit of the day did not come until the sixth, when Fred Lewis took over for Campos. Tomlinson led off the inning with a double, while three other GreenJackets -- Jose Cuevas, Elliott Blair and Charles Jones -- also recorded base knocks in the frame.
"That's one of my goals, to try to throw a no-hitter all the way," Campos said. "But I know I'm in development and I might not throw nine innings. I was looking to give the team a chance to win."
After coming over to the Yankees with Michael Pineda in the offseason trade that sent Jesus Montero and Hector Noesi to Seattle, Campos has not allowed an earned run in two starts with the RiverDogs. Over 11 innings, the native of Venezuela has only yielded a single hit.
So what will he do for an encore his next time out?
"I'll keep working hard and just keep attacking the hitters," Campos said. "Work on my confidence, keep commanding my pitches and go to work every five days."
