Irishman Seamus Power produced the best round of the third day to move into a share of the lead with Ben Griffin at 18-under overall at the Butterfield Bermuda Championship on Saturday.
The co-leaders' three rounds of 195 is a new tournament record and came in difficult conditions with strong winds at Port Royal Golf Course impacting play.
Power carded a third straight six-under 65, bouncing back from a double bogey on the par-three 13th hole with back-to-back birdies on the 16th and 17th holes to grab the lead at a windy Port Royal Golf Course.
The 35-year-old Irishman had managed four consecutive birdies from the second to fifth holes, before he sunk a 30-foot birdie putt on the par-three 16th and brilliantly escaped an awkward lie on a slope on the par-five 17th.
Griffin, who walked away from golf nearly two years ago before returning last season, carded a five-under-round of 66 on Saturday, also coming unstuck on the 13th with a bogey before returning into the joint lead with a closing birdie after an exquisite approach.
Kevin Yu and Aaron Baddeley are next best, tied two shots behind at 16-under overall, with Brian Gay carding his third successive round of 66 to be alone at 15-under overall.
Greyson Sigg and Thomas Detry are a stroke back at 14 under, while Brent Grant shot into the lead early after six straight birdies early but three bogeys and a double bogey on his back nine saw him card a two-under 69 and be 11-under overall.
Halfway leader Ben Crane shot a two-over 73 to slip six shots off the pace and down the leaderboard at 12-under overall. Crane bogeyed four of five holes from the 13th to the 17th to slide out of contention.
