The White Sox promoted Gordon Beckham from Class AA Birmingham to Class AAA Charlotte, and will start for the Knights on Thursday. In 38 games with the Barons, Beckham hit .299 with four home runs and 22 RBI, while scoring 23 runs. Beckham was Chicago's first round pick in 2008. ''This kid is a good ballplayer,'' Ozzie Guillen said. ''A lot of people say the difference between Triple-A and the big leagues is a small step but I don't know about that one. It's the biggest step you are going to make.''
