Asked if it was difficult to stay mentally prepared, Stadler replied, "I'm never really mentally prepared. Same as usual. It was all good."
Tiger Woods, the No. 1 player in the world and in this playoff series, came out of the first delay by missing a short birdie putt on the par-5 13th and then rolling in three straight 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.
Woods didn't mind the long day. He was more concerned about the next long day on the horizon.
Only the top half of the draw finished the round. The later starters Ben Crane played only two holes were to resume the round Friday morning and then go straight to the second round. That left the top half facing extra holes on Saturday to get the tournament caught up.
"We're done," Woods said. "It was a long day, and tomorrow will be a short one. And then Saturday will be pretty much a marathon."
British Open champion Phil Mickelson and Masters champion Adam Scott were among those who didn't finish. PGA champion Jason Dufner had a 71, while U.S. Open champion Justin Rose recovered from a double bogey on the par-5 13th for a 68.
Camilo Villegas, who started the season with conditional status and is No. 110 in the FedEx Cup standings, ran off four straight 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 a 65, along with Henrik Stenson and Ryan Palmer.
"Three breakfasts, three warm-ups, two lunches and a bunch of birdies, which is good," Villegas said.
Edmonton, Alberta • Lydia Ko was 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 a 5-under 65 on Thursday in perfect conditions at Royal Mayfair for a share of the first-round lead with Angela Stanford and Christel Boeljon.
Ko, the South Korean-born New Zealander, had six birdies and a bogey. She birdied the opening hole, though she figured that might be a bad omen.
"When I start off with a birdie I haven't really played that well, so yeah, I was kind of nervous that I did make a birdie on the first," Ko said.
