White Sox Ink Barnum For $950,000

The White Sox have signed supplemental first-round pick Keon Barnum for $950,000. The assigned value for his No. 48 overall slot is $1,052,500.

A first baseman from King HS in Tampa, Barnum offers huge lefthanded power potential but will need to make more consistent contact. He may be able to handle the defensive responsibilities of left field.
