SAN DIEGO - Jason Day worked diligently on his game last week in Palm Springs, looking forward to defending his title at the Farmers Insurance Open, where he won the first of five PGA Tour titles during a breakout 2015 season.
But Day, 28, has been suffering with the flu and wasn't even certain he could tee it up in the first round Thursday at Torrey Pines. He did, and he finished, but he limped home with an even-par 72 after getting to 3 under par early in his round.
"It's mainly just physically, he has no energy,'' Col Swatton, Day's longtime caddie, said.
