Three spots remain open on the White Sox 40-man roster, and another could be created if Brian Omogrosso is moved from the 15-day disabled list to the 60-day disabled list. Right-hander starter Erik Johnson, who is ranked the organization's No. 2 prospect by MLB.com and is a strong candidate for the 2014 rotation, almost certainly will be added, and the same near-certainty holds true for right-handed reliever Daniel Webb, who is ranked the club's 17th best prospect.
Charlie Leesman, whose future with the White Sox is as a left-handed reliever, figures to get a call despite being assigned to the Arizona Fall League. The White Sox will bring up a third catcher, with Bryan Anderson the favorite for that selection. Outfielder Blake Tekotte, who is already on the 40-man roster, could return to the big leagues.
Infielder Marcus Semien, who put himself into the 2014 White Sox infield picture with 106 runs scored and a .278 average between Double-A Birmingham and Triple-A Charlotte this season, was viewed as a solid bet to get a big league call. But with the team's eighth-ranked prospect also going to the AFL, that plan might have changed.
