Rory McIlroy has been playing all year with the Callaway GBB Epic Sub Zero driver, averaging 318 yards off the tee on the PGA Tour.
However, McIlroy released a video of his swing Sunday, and it appears the Northern Irishman will be swinging the TaylorMade 2017 M1 at TPC Sawgrass.
The world No. 2 switched from the Callaway fairway woods to the TaylorMade fairways at this year's Masters.
