Pre-tournament favourite Adam Scott is well poised but Swede Alex Noren rolled in 11 birdies to claim the first-round lead at the PGA Tour's weather-affected Butterfield Bermuda Championship.
Noren posted a career-low, 10-under-par 61 at Port Royal Golf Course to grab a two-stroke cushion with most players in the clubhouse before Thursday's play was suspended under darkness.
After starting on the back nine, Noren made seven birdies over an eight-hole stretch and chalked up his only bogey at the fifth.
