Niemann takes lead at Genesis Invitational with opening 63

Joaquin Niemann started strongest at the Genesis Invitational with an opening round of 63 on Thursday.

A round of nine birdies gave the Chilean a three-shot lead at the Riviera Country Club in Pacific Palisades, California.

Niemann is the ninth player to open with a 63 on the course. Four of the previous eight players went on to win.

Four Americans ended the first day in a tie for second, including Jordan Spieth, while 2021 Open champion Collin Morikawa is a stroke further back.

World number one Jon Rahm, Tony Finau and Xander Schauffele all carded 69 for their opening rounds, as did Rory McIlroy, who dropped shots on the eighth and 13th holes.

Dustin Johnson finished with a two-over-par 73, while Patrick Reed endured a disappointing first day, a double bogey on the 13th resulting in a six-over-par finish.

"Sometimes I think about a score," Niemann said. "Today I was hitting it so good, I had fun just getting into the shot. I didn't really think of the score.

"But then on 18 I was thinking about [it]. I wanted to make birdie so bad. I wanted to make one more.

"You always work to have these kind of days. You always know that you're never going to have these days four days in a row. It's a good way to start.

"I know it's going to be different days during the week, so I've got to be ready for everything and have the best attitude for it."
