Bruce Chen roughed up in rehab start at Class AAA Omaha

Left-hander Bruce Chen took the loss as he allowed four runs on 10 hits over four innings Sunday as part of a rehab assignment with Class AAA Omaha, which lost 4-3 to Oklahoma City.

Chen, who is on the disabled list while recuperating from a bulging disk in his back, struck out one, didn’t walk a batter and allowed a home run.

“I think he’s still feeling his way through a bit. He gave up some hits, but nothing was really hit hard,” manager Brian Poldberg told the Omaha World-Herald.

Clayton Mortensen gave up just two hits over the last five shutout innings. He struck out six and walked one.

Center fielder Brett Eibner had three hits, including two doubles and scored twice. Third baseman Johnny Giavotella also had a three-hit game.
