There were only minor differences in McIlroy's club lineup in his encore victory in Akron, Ohio. Instead of the Nike MM proto 2-iron he carried at Hoylake, McIlroy had a VRS Covert 5-wood (19 degrees). He also took out his VR Pro Blade 3-iron in favor of a third VR Forged wedge, adding the 52 degree to the 54 and 59 degree models he previously carried.
