A second successive round of 66 gave Patrick Reed a three-shot lead after the second round of the Hero World Challenge in the Bahamas.
The American only dropped one shot during his six-under-par round and is now three shots ahead of joint overnight leader Gary Woodland, who birdied his final three holes in a 69.
Tiger Woods, who hosts the event, moved into contention, a eagle three at the 11th the highlight of his round of 66, which left him six shots behind Reed in a tie for fifth.
Swede Henrik Stenson and Spaniard Jon Rahm are tied for third on eight under, four shots back.
Woods is level with Justin Thomas and Rickie Fowler while Justin Rose, the only Englishman in the field, sits eighth after bogeying the last two holes in a round of 70.
