McIlroy went into the final round a shot behind Ryder Cup team-mate Sepp Straka and was tied for the lead at the turn, only to pull clear of a congested leaderboard with a stunning start to the back nine.

The weather brought back romantic images of the old “Crosby Clambake,” with a cold wind whipping off the Pacific Ocean and light rain, generally miserable weather for golf except at Pebble Beach — at least for those watching.

Sepp Straka narrowly reclaimed the lead at the end of the third round of the AT&T Pebble Beach Pro-Am, holding off the charging Rory McIlroy and Shane Lowry. The Austrian, who had a three-shot halfway lead in his bid to claim a second win of the PGA season, birdied four of his last five holes in a third-round 70 as he moved to 16 under par.
