Ventura waiting for September to talk callups

BOSTON -- Manager Robin Ventura knows how many players the White Sox will be calling up from the Minors when rosters expand on Sunday. Until then, Ventura will keep that information on a need-to-know basis.

"There will probably be a couple here and a couple more in New York," Ventura said. "I know the number, but we're making sure that they know before everybody else knows."

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.
