At the start of this tournament, all eyes were on Phil Mickelson. He is the defending champ and he is coming off of a dominant wire-to-wire victory at the Phoenix Open last week. 

You can get a good feel for his day by this sequence of shots that resulted in a par on No. 4  on the Monterey Peninsula course. 

It isn't often that Lefty is going to be off enough on a chip to hit someone else's ball, but that is the kind of day it was for Mickelson. He is striking the ball well, and he hit nine out of 12 fairways, but his putter let him down on Day 1. 

This left Mickelson with a one-under 69 for the round, and looking way up at our leaders. However, he is certainly within striking distance.  

Speaking of our leaders, Russell Knox carded his six-under by firing a 64 on the Monterey course. 

Knox started off his round with a bogey, but he then birdied six of the next 11 holes, and if he would have been just a bit more true with the below birdie putt on No. 9, that stretch would have been even more prolific: 

Meanwhile, Hunter Mahan had his fantastic ball-striking working for him. Check out this fantastic approach shot on No. 11 on Pebble Beach.  

Look at that smooth and paced swing. In my dreams, that is what my own swing looks like.

If Mahan can stay consistent with his short game over the next three days, he could run away with this tournament. 

Of course, this wouldn't be a Pebble Beach Pro-Am recap without a look at the incomparable Bill Murray. So what about Bill? 

He was the tournament's unofficial winner the second he proved he could rock this Tom Morris-inspired facial hair. 

Like most of us, Murray can hit some duffers, but this approach shot would make even Carl Spackler happy:

While Murray, Mickelson and our two leaders take a lion's share of the attention, they didn't hog it all. Vijay Singh is in action for the first time since admitting he used deer antler spray, which contains a banned substance (in case you haven't been paying any attention to sports for the past three weeks). 

He was wildly erratic and wound up with an even-par 72 on Pebble Beach after firing just 10 pars on the day. 

He did not talk to reporters after his round.
