Golf’s best descended on Whistling Straits in Wisconsin for the 97th PGA Championship Thursday morning, with the top trio of No. 1 Rory McIlroy, No. 2 Jordan Spieth, and Zach Johnson highlighting the tournament’s first round.

McIlroy, the defending champion and two-time PGA-winner, returns for the first time from a serious ankle injury that forced him to sit out the British Open last month against the young player trying to steal away his top ranking, 22-year-old Spieth.

They will lineup with Johnson, who’s never finished higher than tied for third at the PGAs, at 2:20 p.m. ET from the No. 1 tee.

That will certainly be the marquee grouping in the afternoon, but in the morning Rickie Fowler, Jason Day, and Dustin Johnson will be the matchup to watch. They began the first round at 9:05 a.m. ET.

Of that group, Fowler’s played the best at the tour’s final major, finishing tied for third last year only two strokes back of McIlroy and one away from Phil Mickelson.

Tiger Woods also opened the tournament with two other previous champions, Martin Kaymer in 2010 and Keegan Bradley in 2011, starting at 9:15 a.m.
