The White Sox could promote last year's first-round pick, Aaron Poreda, from Double-A Birmingham to pitch Tuesday against the Mariners, according to The Chicago Tribune. Manager Ozzie Guillen said Chicago would wait until after Monday night's game to name a starter. Poreda has a combined 3.38 ERA with 102 strikeouts and 37 walks in 144 innings at Class A Winston-Salem and at Birmingham.
