Alex Smalley's two-shot lead will be tested Sunday at the PGA Championship by a list of blockbuster chase groups at Aronimink.
Smalley and Matti Schmid tee off at 2:35 p.m. ET in the final group of the day. But it's the three preceding pairings that'll surely grab the headlines, with Jon Rahm in the penultimate group alongside Nick Taylor, and Ludvig Aberg and Aaron Rai starting at 2:15 p.m.
However, the most accomplished pairing features Rory McIlroy and Xander Schauffele, who tee off at 2:05 p.m. Combined, they have won eight majors.
