LOS ANGELES — Rory McIlroy would have preferred playing in the rain compared with the wind that followed Thursday at Riviera. He handled both well enough for a 5-under 66 to share the clubhouse lead with Jacob Bridgeman in the Genesis Invitational.
Scottie Scheffler couldn't get off the course fast enough. He was tied for last in the 72-man field, without a birdie through 10 holes when play was suspended by darkness.
The rain that formed puddles on the already soft greens led to a three-hour stoppage. Players returned to far more difficult conditions with a wind that was strong and cold, and putting surfaces with a rare combination of being super soft and super quick.
McIlroy opened with three birdies in four holes. He saved par on the par-3 sixth by chipping over the bunker in the middle of the green. He dropped only one shot to join Bridgeman, who contended last week at Pebble Beach and played his best in the strongest conditions.
''I've started to just really enjoy this style of golf,'' said McIlroy, who grew up in Northern Ireland but spoke early in his career of his fondness for warmth and sunshine.
''If you had asked me 10 years ago, I didn't enjoy these conditions, but it's been a shift in a mindset and maybe just a continuation of trying to build upon the skill set that I have,'' he said. ''Then when it does get to conditions like this, I'm a lot more prepared. I wouldn't say I enjoy them, but I can certainly handle them better.''
Aaron Rai was at 6 under with two holes remaining when it was too dark to continue. The round was to resume Friday morning, and the forecast was dry for the rest of the week.
Ryan Fox had a 67, and Pebble Beach winner Collin Morikawa was in the group at 68.
