Jordan Spieth plays his second shot on the fourth hole during the second round of the Farmers Insurance Open golf tournament at Torrey Pines Municipal Golf Course - South Course.
The three-time major champion has fallen down the official golf rankings to 21st in the world since his last win, while Spieth has not posted a top-10 finish since the 208 Open Championship.
Mickelson, who is chasing his 50th career victory, was flawless from the tee as he hit 13 out of 13 fairways - the first time he recorded a 100 per cent success rate in that department on the PGA Tour since 1998, although he was unaware that he had managed this before. "I'm not going to chase them as hard as I tried to maybe force or chase them past year because you can get hurt doing that".
"I have the honour to play all three courses here and, just because of such attractive scenery, I couldn't even focus on where my ball was going", Choi said of Pebble Beach Golf Links, which is set on the famed Monterey Peninsula. "So that was a big milestone for me".
"I have the honour to play all three courses here and, just because of such lovely scenery, I couldn't even focus on where my ball was going". "This was a day we had great weather, courses were very "scoreable", so you needed to take advantage of that".
Spieth was even at the turn but ran in five birdies coming home.
Gay strung together five straight birdies to close his front nine, and then had three more in his final five holes.
"I'm really happy about the back nine".
Dustin Johnson, coming off a victory in Saudi Arabia last week and a two-time victor at Pebble Beach, is among nine players at 5 under. Both played at Monterey on Thursday.
Pebble Beach will also host the U.S. Open in June when the course is likely to be much drier than the damp, lush conditions that will greet players this week after recent heavy rains.
Korean Ho Sung Choi, whose unique "Fisherman Swing" has made him an internet sensation, shot a 1-over 72 at Pebble Beach in the 45-year-old's first round in a PGA Tour event.
