Burns, a right-handed reliever, was called up last Thursday when Alexi Ogando went on the disabled list. He allowed two runs over 3 2/3 innings over three appearances. He had a 1.38 ERA in 14 outings with the Express when he was called up. The move cleared a roster spot for today's spot starter Ross Wolf, a 30-year-old right-hander seeing his first big-league action since 2010. Wolf has gone 1-2 with a 2.02 ERA over seven games, including six starts, with Double A Frisco and Round Rock this season.
