Chapman may not be available out of the bullpen for Friday's day game against the Mariners, Jesse Rogers of ESPN Chicago reports.
The flamethrowing lefty has pitched two consecutive days, and with a matinee game looming Friday, manager Joe Maddon may avoid using Chapman in order to preserve his arm. Chapman recorded a four-out save Thursday, tossing 24 pitches. If he's indeed unavailable Friday, Hector Rondon would be the likely candidate to take the mound should a save opportunity arise.
