Newcomb will serve as the White Sox's opener for Sunday's game against the Mets, Brooke Fletcher of Chicago Sports Network reports.
The White Sox will deploy Newcomb as a starter for a second straight appearance and for the third time in his past four outings. He's made three total starts this season and hasn't covered more than three innings on any occasion, so he'll presumably be in line for another light workload Sunday. Erick Fedde is the leading candidate to pitch in bulk relief behind Newcomb.
