Collin Morikawa will take a commanding five-stroke lead into the final round of the Hero World Challenge on Sunday after shooting an eight-under par 64 to edge closer to becoming world number one.

The 24-year-old American made six birdies and an eagle chip-in to stand on 18-under after 54 holes of the 20-man invitational hosted by Tiger Woods at the Albany resort in the Bahamas.


Brooks Koepka, the four-time major winner, shot 69 to stand second on 203 and join the reigning British Open champion in Sunday's last pairing.

If he wins for a fourth time in 2021, Morikawa will become only the fourth player under the age of 25 to become world number one.

Patrick Reed, Viktor Hovland, Daniel Berger, Sam Burns and Tony Finau are all one further back on 12 under while overnight leader Bryson DeChambeau hit a round of 73 to sit in ninth heading into the final round.

Rory McIlroy, meanwhile, slipped down to 18th after a three-over-par round, his round blighted an unsightly nine on the par-5 11th which effectively ended his bid.
