Athletics' designated hitter Jack Cust seems puzzled by two particular aspects of his inclusion in the Mitchell's Report on doping in baseball, as reported by One, that he was accused of using steroids. And two, that he apparently was assigned a locker beside former minor league teammate Larry Bigbie -- the source behind Cust winding up in the report. In his first public remarks, Cust told Bay Area media that he has never used performance-enhancing substances. "No. No. Not even one game," he said Saturday.
