Collin Morikawa carded a six-under-par 66 to claim a one-stroke lead before bad weather halted the opening round of the Memorial Tournament.
Thunderstorms forced a weather-hit day one to be suspended at Muirfield Village, where Morikawa managed to set the early pace before play was stopped on Thursday.
Morikawa – last year's US PGA Championship winner – was almost flawless in Dublin, Ohio after holing seven birdies and just one bogey.
A run of three consecutive birdies and four in five to start his back nine sent Morikawa to the top of the leaderboard, just ahead of fellow American Adam Long.

Round 1 of @MemorialGolf will resume Friday at 7:30 a.m. ET.
"It was definitely the rain," Morikawa said. "The greens were soft enough and they're receptive. But you have to hit the fairway. Out here, wet rough, it's not going to help when the rough is pretty long.
Bo Hoag, Nick Taylor, Xander Schauffele and Rafa Cabrera Bello also completed their rounds and ended the day two strokes off the pace, while defending champion Jon Rahm, Justin Thomas and Rickie Fowler are among a group a shot further back at three under.
Reigning U.S. Open champion and 2018 Memorial Tournament winner Bryson DeChambeau – gearing up for his upcoming title defence at Torrey Pines Golf Course in San Diego this month – was two under through three holes at the time of the suspension.
Former world number one Jordan Spieth also completed three holes – one under – when play was called off, while Masters champion Hideki Matsuyama, who won the PGA Tour event in 2014, did complete his round following a one-over-par 73.
Four-time major champion Rory McIlroy will return to finish his round early on Friday after going one over through two holes in wet conditions.
