Scottie Scheffler, Rory McIlroy and defending champion Xander Schauffele -- the world's highest-ranked golfers -- tee off together Thursday morning in a showcase group certain to seize the spotlight at the PGA Championship.

Masters champion Rory McIlroy and world No. 1 Scottie Scheffler will be playing together in the opening two rounds of the PGA Championship, joined by defending champion Xander Schauffele in another group of the top three players in the world.

Scottie Scheffler and Rory McIlroy are the early betting favorites ahead of this week's PGA Championship at Quail Hollow, but Bryson DeChambeau is garnering plenty of action from bettors with the third-best odds to win the tournament.
