LOS ANGELES (AP) — Tiger Woods began with an unknowing tribute to Kobe Bryant by making an eagle putt that optical cameras measured at 24 feet, 8 inches. He ended his opening round with a reminder that getting around Riviera unscathed is no small task.

That’s what made Matt Kuchar’s day all the more remarkable.

Kuchar drove to the edge of the 10th green and two-putted for birdie and kept right on rolling until he had a 7-under 64 on Thursday, matching his best score at Riviera and giving him a three-shot lead in the Genesis Invitational.

So clean was Kuchar’s round that he only once had to stress over a par putt, and he made the 10-footer at the par-3 fourth.

The conditions were ideal once the morning chill gave way to mild sunshine, and Kuchar took advantage in the morning. As much as Kuchar loves the course, he has only one top 10 in his 13 previous appearances.

Woods was 4 under through eight holes and had to settle for a 69.
