The White Sox are utilizing the 27th man rule for Thursday’s doubleheader to bolster the pitching staff. Right-hander Owen White has been appointed from Triple-A Charlotte, and is available for both games of the doubleheader. Teams carry a 26-man roster for most games, but they are allowed to recall one additional player from the 40-man roster for doubleheaders. Per MLB.com, that player accrues one day of MLB service time and is returned to the Minor Leagues following the completion of the doubleheader.
