Dustin Johnson birdied the final hole Friday for a 6-under 66 and a share of the lead with Hideki Matsuyama in the Hero World Challenge.
Johnson wasn't even planning to be in the Bahamas. He was scheduled to play an exhibition with Rory McIlroy in the Philippines earlier this week. But he never withdrew in case the match fell through, which it did.
Matsuyama, who has won three of his last four tournaments, shot a 67.
They were at 12-under 132, two shots ahead of Matt Kuchar and Louis Oosthuizen, who each had a 67.
Tiger Woods, in his first competition in 15 months, shot a bogey-free 65 and was six shots behind in a tie for ninth. Woods played as a single because Justin Rose withdrew with back problems.
