Prior stranded the bases loaded after allowing a pair of singles and walking a batter in the fourth inning of Oklahoma City's 9-1 loss to the Omaha Royals. It was the first game for the former first-round draft pick and All-Star pitcher after signing a minor league deal with the Texas Rangers.

Prior is trying to make a comeback after two shoulder injuries forced him to miss the 2007 and 2008 seasons. The right-hander went 42-29 in five years with the Chicago Cubs and was an All-Star in 2003.

He started his comeback in the independent Golden Baseball League last month before being acquired by the Rangers.
