Jason Day comes through a four-way play-off to win at Torrey Pines

Fog delayed the opening stages of the Farmers Insurance Open and indirectly lead to Tiger Woods having back problems. “I was ready to go,” explained the world number 56. “I had a good warm-up session and then we stood out here getting cold and everything deactivated again. My glutes [gluteus maximus muscles] are shutting off. If they don't activate it goes into the lower back. I tried to activate my glutes best I could but they didn't stay activated."

This back problem meant Tiger Woods withdrew after playing 11 scrappy holes in which he again demonstrated erratic chipping which further suggested he has the yips after his similar travails at the Phoenix Open.

Phil Mickelson missed the cut at the Farmers Insurance Open by three strokes, the first time since 2002 that he has missed cuts in consecutive weeks. He described his putting as "beyond pathetic. I spent a lot of time in the off season with ball-striking, with driving, with a lot of the areas that I'm doing well right now, primarily because I thought my putting was fine. I had putted phenomenal all of 2013 and even the last few months of 2014. I felt that wasn't going to be an issue, but it is."

Mickelson is currently ranked 18th in the world. Others who failed to qualify for the weekend included world number five Justin Rose and number nine Jordan Spieth. Dustin Johnson, in his first tournament since July, missed the cut by a single shot.

This is a course where hang time can take on a different meaning.
