From Tiger Woods' feeling off to a big final group with Rory McIlroy and more at the Genesis Invitational

LOS ANGELES -- Riviera Country Club continues to confound tournament host Tiger Woods, who will not win his hometown event and the one he now hosts, extending the run to 14 times -- the most of any event he has not won.

Woods still has work to do on Sunday to try to salvage something from a lost week, while Rory McIlroy will attempt to win in his first start as the newly crowned No. 1 golfer in the world. Here are a few things to watch during the final round of the Genesis Invitational:

1. Is Tiger hurting?

Woods admitted he felt stiff Saturday, and this is part of the deal for him at age 44 and having endured four back surgeries. The difference now compared with earlier times is that he knows better than to push through his issues. And that helps explain why he is skipping next week's WGC-Mexico Championship.

That tournament appeared to be a lock on his schedule, and it was a surprise he was skipping it, leading to all kinds of conjecture. He tied for 10th in Mexico City last year despite a poor putting week. With a more complete game now, the feeling was he might be able to do some damage there.

What Woods didn't say is that the idea of playing four times in five weeks -- the likely number had he entered Mexico -- was not appealing. He looked tired, and at times played that way during a third-round 76, his highest competitive score in six months.

And so it remains to be seen if he adds the Honda Classic or the Arnold Palmer Invitational -- not both -- before playing the Players Championship. If he then plays the WGC-Dell Technologies Match Play, at which he tied for fifth a year ago, that would be five starts prior to the Masters -- just like in 2019.

"That's the fun part of trying to figure this whole comeback,'' he said. "How much do I play, when do I play, do I listen to the body or do I fight through it? There are some things I can push and some things I can't.''

There were plenty of good reasons to go to Mexico, not the least of which was a shot at victory in a limited-field event on a course on which he had a good result despite not playing that well. But he appears to be taking the cautious approach, and it is hard to argue with that.

Woods is tied for 63rd and 15 shots back of the leaders.

2. Scott's resurgence

Adam Scott is playing for the first time in 2020 after winning the Australian PGA Championship in December. That was his first world-wide victory in more than three years, and he's going on four years without a win on the PGA Tour.

He has put himself in position at Riviera with rounds of 64 and 67 after a slow start and a 72 on Saturday. In 2005, Scott won at Riviera in what was an unofficial victory because the tournament was shortened to 36 holes. He calls it one of his favorite courses on tour.

"I should probably say that about more courses on tour, but it really is,'' he said. "I enjoy coming here very much, and I just feel the course ... there's nothing too tricky to it. I just feel my game matches up well for it, so I look forward to it every year.

"The only unfortunate thing about it is it's usually my first tournament of the year, and I'm going to have to find some other favorites later this year.''

Scott is among the top 5 through 54 holes for the first time on the PGA Tour since last year's Memorial.

3. Final-group firepower

Scott will be joined by McIlroy and Matt Kuchar in the final threesome Sunday at Riviera. All are tied at 203, 10 under par. And combined, they have 40 PGA Tour victories and more than $155 million in official PGA Tour earnings.

4. Solidifying the No. 1 spot
