Collin Morikawa, Jon Rahm and J.J. Spaun share the lead after carding nine-under-par rounds of 64 on the first day of the season-opening Tournament of Champions in Hawaii on Thursday.
Two-time major winner Morikawa reeled off a career-best six straight birdies from the 10th to 15th holes, before ending his round with a birdie on the par-five 18th.
Fellow American Spaun was an early leader with five birdies on his front nine, enjoying a run of four consecutive birdies from the 12th to the 15th too.
Former world number one Jon Rahm, who was among the last to finish the day's play, bounced back from a bogey on the 14th hole, birdieing three of his final four holes to grab a share of the lead.
The trio are one stroke ahead of South Korean Tom Kim, who managed two eagles in his eight-under-par round of 65. Kim holed out spectacularly off one bounce on the sixth hole from 116 feet, while he repeated the feat on the 15th after a fine approach which was one of the best shots of the day.
Six players are next at seven under, including world number two Scottie Scheffler who finished his round with four birdies on the final five holes.
Scheffler is tied with Tom Hoge, Aaron Wise, Sungjae Im, Matt Fitzpatrick and Mackenzie Hughes.
Six players are a further shot back including Jordan Spieth, Viktor Hovland and Hideki Matsuyama.
