The White Sox signed right-hander Al Alburquerque to a minor league deal on Friday. Alburquerque was released by the Royals last week and has made just 11 big league appearances this season. He has been assigned to the White Sox’ Triple-A Charlotte, where he’ll attempt to exhibit more consistency on the mound before making another leap to the majors.

Alburquerque, 31, has seen limited major league opportunities over the last few seasons. He picked up a minor league contract with the Angels to start the 2016 season, but pitched only two innings before being demoted to Triple-A Salt Lake and was finally released by the club in August.
