Source: RotoWorldDarin Erstad will sign a one-year deal with the White Sox, MLB.com reports.
An option for 2008 is included. Erstad is set to battle Brian Anderson and Ryan Sweeney for the center field job this spring. He could also play some left if Scott Podsednik isn't going to be ready for the beginning of the season. Ideally, he'd be a fourth outfielder. However, there's a good chance he'll play over Anderson against right-handers until he gets hurt again.
