MLB.com's No. 7 prospect held Class A Advanced Myrtle Beach to two hits over five innings as the Frederick Keys blanked the Pelicans, 3-0.
Making his fifth Carolina League start, Bundy (3-2) struck out two and walked two. It was the first time he did not allow a run for the Keys.
"It's probably my best outing in High-A, other than the two walks," said Bundy, who threw 36 of 60 pitches for strikes. "I was kind of disappointed in that, but for the most part I threw the fastball well in the zone tonight."
Both hits off Bundy came relatively early: Christian Villanueva singled in the first and Odubel Herrera singled in the third. Bundy suffered some mild control issues in the fourth, issuing consecutive walks to Tomas Telis and Brett Nicholas, but he got Vincent DiFazio to hit into a double play.
Working off his heater, Bundy used his changeup to give hitters a different look.
"I located it inside and outside on left-handed and right-handed batters," he said. "I was keeping it low and using it effectively."
Over 23 2/3 innings for the Keys, Bundy has a 3.42 ERA with 25 strikeouts and eight walks. The Oklahoma native said hitters at this level have "a little bit more of a plan," so he goes to his off-speed stuff more often.
"A lot more secondary pitches," he said. "If you miss with a fastball early in a count, they can usually time it up pretty well."
Across two levels, Bundy owns a 1.51 ERA and 65 punchouts in 53 2/3 innings. The fourth overall pick in the 2011 Draft has parlayed that success into a selection for the All-Star Futures Game, where he will be joined by Orioles top prospect Manny Machado.
"It's a great feeling, a good honor to have," Bundy said. "I'm very blessed to go there and with a teammate, Manny Machado, as well. It'll be nice to have a teammate with me."
