Jon Rahm hardly missed a shot and found golf easy Friday on his way to a 9-under 63, giving him a share of the lead with Henrik Stenson going into the weekend at the Hero World Challenge.

Tiger Woods stayed eight shots behind, and an 18-month-old rules decision kept him from being a further stroke back. He hit into a palm bush on the 18th hole on his way to a double bogey. Video evidence revealed he hit the ball more than once, but Woods wasn't given an additional penalty shot because of the rule that players aren't penalized if it can't be seen by the naked eye. He shot 69.

Stenson ran off three straight birdies late in his round for a 66.
