MILWAUKEE -- With successful debuts in the books for two of the three starting pitching prospects acquired by the Brewers in non-waiver Trade Deadline deals, it was Zach Davies' turn on Wednesday.

Davies, the 22-year-old right-hander obtained from the Orioles for outfielder Gerardo Parra, allowed a run on six hits and struck out seven batters in six quality innings for Triple-A Colorado Springs against a talented Dodgers affiliate in Oklahoma City. He followed the lead set at Double-A Biloxi by right-hander Adrian Houser and left-hander Josh Hader, each of whom were acquired from the Astros in the Carlos Gomez /Mike Fiers trade and logged successful Brewers debuts this week.

Hader was particularly impressive on Tuesday in Mobile, Ala., combining with two relievers in a three-hit shutout. The 21-year-old surrendered only one hit and one walk while striking out nine batters in five innings. The strikeout total was one shy of his career high as a pro.

"Pretty dominant," Brewers manager Craig Counsell said.

The Brewers had been fans of Hader for a while. He previously pitched in the Orioles' system, and was one of the players discussed in 2013 when the Brewers traded Francisco Rodriguez to Baltimore.

On Monday, Houser struck out six batters and allowed three runs in 5 2/3 innings of a no-decision. Like Hader, he struck out the first batter he faced as a member of the Brewers organization.

Hader and Houser joined the Brewers' most competitive affiliate. Biloxi entered play Wednesday with a 43-25 record, and has already clinched a spot in the Southern League playoffs. Among the Shuckers' players are top Brewers prospect Orlando Arcia and new No. 2 prospect Brett Phillips, an outfielder acquired with Hader and Houser as part of the package for Gomez and Fiers.

"There's been some purpose to that, keeping those guys together and having that team perform together," Counsell said. "They're going to go to the playoffs so they'll get to experience that together.

"It's exciting. It definitely puts a smile on everybody's face, that's for sure."
