Prospect Barnum out six weeks after hand surgery

GLENDALE, Ariz. -- Keon Barnum, the White Sox sandwich pick (48th overall) in the 2012 First-Year Player Draft, had the hamate bone removed in his right hand during a surgical procedure Monday. The expected recovery period is six weeks.

The 6-foot-5, 245-pound first baseman sustained the injury last week, after the 20-year-old was limited to 13 games at advanced Rookie League Bristol last year and didn't play from June 24 to Aug. 3 and from Aug. 13 through the end of the season because of a shoulder problem.

Barnum, who is rated by MLB.com as the organization's seventh-best prospect, went 0-for-3 in his first pro game last year and then homered in his next three games and went 7-for-12 with seven RBIs.
