There was speculation the Yankees would start CC Sabathia instead of Hughes in Game 4 if they were facing elimination, but manager Joe Girardi put an end to that before the game.
"Hughesy will start tomorrow," Girardi said before the Yankees beat the Orioles 3-2 in 12 innings on Wednesday in Game 3 of the AL Division Series.
Among Girardi's reasons for starting Hughes are the manager's preference to have Sabathia on full rest for a potential Game 5 on Friday, and his qualms about using Andy Pettitte on short rest if he went to Sabathia in Game 4.
Sabathia started Game 1 on Sunday, while Pettitte threw Game 2 on Monday.
Joe Saunders will start Game 4 for the Orioles, the team announced after Wednesday night's game.
