Rookie right-hander Kumar Rocker pitched five scoreless innings with help from some pickle juice, Ezequiel Duran put Texas in front for good with an RBI double and the Rangers finished a sweep of the Chicago White Sox with a 2-1 victory on Sunday. Rocker (2-4) twice got visits from the trainer with apparent cramping in his legs in the fifth, and quickly chugged three bottles of pickle juice along the way, while getting through the inning.
