QUOTE OF THE DAY

World number 119 Danny Lee, who won on the European Tour as an 18-year-old amateur, reflects on the ups and downs of the professional game.

"It's definitely tough out here playing in the Tour golf life. It's not easy. Some of the top 20 guys in the world make it look easy, but it's not always fairy-tales and unicorns out here.

"People gotta understand it's not just for everybody. And when things are not going your way, for life in general, it tears you down."

SHOT OF THE DAY

Tiger Woods, Jordan Spieth and Rickie Fowler were among the players to make a double bogey on the 10th hole, while Thomas Pieters started his round there with a seven. In contrast, American Max Homa made it look routine after an approach from 194 yards to five feet set up one of the seven birdies there all day.

ROUND OF THE DAY

Brooks Koepka was perhaps fortunate to hole from off the green for birdie on the 10th, his opening hole of the day, but there was very little luck involved in the six birdies which followed to give the three-time major winner a course record of 63.

STATISTIC OF THE DAY

Former Golf Channel statistics guru Justin Ray points out the size of the task facing Tiger Woods (and Rory McIlroy) after day one.

TOUGHEST HOLE

Although the 10th garnered a lot of attention, the uphill par-four 15th played as the toughest hole, offering up just four birdies against 10 double bogeys and one triple bogey for a scoring average of 4.577

EASIEST HOLE

The par-five fourth played as the easiest hole with Tiger Woods carding one of the three eagles and 65 players making birdie for a scoring average of 4.628

ON THE UP
