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.

Ben Crane shot Friday's round of the day at the Butterfield Bermuda Championship, with his nine-under 62 propelling him to the top of the leaderboard heading into the weekend at 14 under.

In his second trip around Bermuda's Port Royal Golf Course, Crane collected nine birdies and one eagle with his two bogeys to sit alone atop the leaderboard as the 46-year-old seeks his first PGA Tour win since the 2014 FedEx St Jude Classic.

He is one stroke clear of a five-man group at 13 under, including joint first-round leader Austin Smotherman, as well as rising talent Robby Shelton and Australia's Aaron Baddeley.

A strong international contingent is tied for seventh at 12 under, headlined by Ireland's Seamus Power, and he is joined by Taiwan's Kevin Yu, China's Zecheng Dou and Colombia's Nico Echavarria.

Belgium's Thomas Detry and Argentina's Fabian Gomez are at 11 under, while Harrison Endycott – who was tied with Smotherman for the first-round lead – followed his opening 62 with a disappointing 70 to enter the weekend four strokes off the pace.

Caleb Surratt is the top amateur in the field at seven under after enjoying a strong seven-under 64 in his second round, shaking off the nerves following his 71 on Thursday to sit well inside the projected cut-line.
