The FedEx Cup playoffs got off to a soggy start Thursday with two rain delays that lasted six hours.
Stadler ran off three birdies early, then returned from the second delay and threw in four more birdies.
Camilo Villegas ran off four consecutive birdies around the turn and was the only player to reach 8-under – for now – until back-to-back bogeys late in his round. He had 65, along with Henrik Stenson and Ryan Palmer.
Tiger Woods came out of the first delay by missing a short birdie putt on the par-5 13th and then rolling in three consecutive birdies to get into the mix. He cooled slightly after the slightly longer second delay, and failed to make birdie on any of the par 5s in his round of 67.
U.S. Open champ Justin Rose recovered from a double bogey on the par-5 13th for 68, while PGA champion Jason Dufner had 71.
EUROPEAN TOUR: In Gleneagles, Scotland, Bernd Weisberger and Ricardo Gonzalez took full advantage of ideal scoring conditions to shoot 7-under-par 65 and share a one-shot lead after the first round of the Johnnie Walker Championship.
Ex-Augusta State golfer Scott Jamieson had 72.
LPGA TOUR: In Edmonton, Alberta, Lydia Ko is back on top of the Canadian Women’s Open leaderboard.
The 16-year-old Ko, the winner last year at Vancouver Golf Club at an LPGA Tour-record age of 15 years, 4 months, shot 5-under-par 65 at Royal Mayfair for a share of the first-round lead with Angela Stanford and Christel Boeljon.
WEB.COM TOUR: In Omaha, Neb., Billy Hurley III and Andrew Loupe shot 8-under-par 63s to share the lead in Cox Classic at Champions Run.
Augusta’s Scott Parel and Aiken native Matt Hendrix had 67s. Aiken’s Kevin Kisner shot 74.
