BALTIMORE -- The Astros made a flurry of roster moves Friday, with Scott Feldman getting activated to face the Orioles in the series opener at Camden Yards. Also, left-handed starter Brett Oberholtzer was sent to Triple-A Oklahoma City and right-handed reliever Jose Cisnero was placed on the 15-day disabled list with right elbow discomfort.
The team also recalled right-hander Paul Clemens, who makes his second stint with the club and will pitch out of the bullpen. The right-hander made four appearances with Houston in April and posted a 4.73 ERA over 13 1/3 innings.
"I feel great right now," he said. "I feel good with all my stuff. I have a year of experience under my belt now and know what these hitters like to do and like to look for, and now it's time for me to adjust to them and do what I know I'm capable of doing."
The return of Feldman from the disabled list meant the Astros had to open up a spot in the rotation, which is why Oberholtzer was sent out. The lefty was 0-6 with a 5.68 ERA in seven starts this season.
"It was a tough decision," Porter said. "Last year, you look at the success that he had in the big leagues and early in the year he pitched well and had a couple of rough patches here his last start, but I felt even the last start he competed and had us in position to mount a comeback in the game. You look at the overall situation and how well the other guys had thrown the ball, we felt like it was the right decision to make at the time."
Cisnero has been with the Astros since being recalled from Triple-A on April 25. He made his fifth appearance of the season Tuesday in Detroit, where he injured his elbow.
