Peacock admitted he was worried about the pain and soreness, and the Astros wanted to play it safe by giving him some extra time. He's scheduled to return to the rotation Thursday when the Astros open a homestand against the Orioles.
After four relief appearances to start the season, he's made six starts and posted a 4.58 ERA. He's thrown at least six innings in his last four starts, striking out career-high 11 batters May 12. The Astros called up Rudy Owens to start for Peacock on Friday and then immediately shipped him back to Triple-A. Lefty Brett Oberholtzer was called up to start Saturday, giving each of the starters an extra day of rest.
