For pitcher Bud Norris, Wednesday's trade meant a short walk down the hallway.
After starting 21 games with the Astros and originally being scheduled to start for them on Tuesday, Norris will instead start against Houston and for the Orioles in the series finale on Thursday. He will be opposed by Astros right-hander Jordan Lyles.
"This is a business, and like I said to Bud, it speaks to how he's been doing as a Major League player that he was having a number of teams call us with interest in him," Astros manager Bo Porter said. "He's going to a great situation over there in Baltimore, a great opportunity to play for a championship. I wish him well. I think we have enough young pitching in our organization that we feel comfortable moving forward."
Norris was 6-9 with a 3.93 ERA for Houston this season. He was traded for outfielder L.J. Hoes, left-handed pitching prospect Josh Hader and a Competitive Balance Draft pick.
"The trade is exciting. My name has been swirling for a while now, so I've been prepared for it," Norris said. "I've seen a lot in four years down here in Houston with what's going on. I commend them for that. It's a very tough, challenging time. But I'm excited for the future. I pitched my way into this situation to be traded and help out a team. This team is a young club, they know how to contend. They had an amazing year last year. I just want to be any piece of the puzzle I can to help this team keep pushing ourselves to the World Series."
Norris joins an Orioles team that sits in third place in the American League East. He will be the 14th starting pitcher used by the O's this season.
"Baltimore was in the hunt of things," Norris said. "I really thought once they got Scott Feldman my chances went down. But obviously we got a couple guys now. It's really out of your hands. I have no say in the matter where I go. I have no trade clauses in my contract. I'm excited for the opportunity. I just want to get on the field as soon as I can and pitch."
Lyles is 4-4 with a 4.92 ERA through 16 starts. He's winless since June 18 and 0-3 in his last six starts.
In his last start, he allowed four runs on nine hits in five innings with three walks and a strikeout.
Astros: Oberholtzer notches first win
Brett Oberholtzer, who was acquired earlier in the season from Atlanta, made the first start of his big league career against the Orioles on Wednesday night.
He pitched seven scoreless innings, allowing just three hits with seven strikeouts. Prior to Wednesday, he made three relief appearances, going 0-0 with 10 strikeouts in 14 1/3 innings.
Orioles: Machado on a doubles drought
Despite leading the Major Leagues with 39 doubles, Manny Machado has not hit one in his last 20 games. His last double came in the third inning on July 6 against the Yankees. The 20-game stretch without a double is the longest of his career.
• Astros outfielder Robbie Grossman is 6-for-10 in his first three starts since being recalled from Triple-A Oklahoma City on Saturday. One of the six hits was his first big league homer, a blast onto Eutaw Street on Wednesday night.
• Nick Markakis is on an eight-game hitting streak, going 13-for-32.
