Casey Jarvis leads after the first day of the Genesis Championship

South African golfer Casey Jarvis took the lead after the first day of the Genesis Championship, the final event of the DP World Tour's regular season. The 23-year-old finished his round at Woo Jeong Hills Country Club with a birdie on the last hole and moved ahead of Sanghun Shin.

Jarvis, who has already won twice this season, is fourth in the Race to Dubai standings. On the current table he will pass Rory McIlroy and Patrick Reed. He is expected to enter the DP World Tour Play Offs in second place, behind leader Eugenio Chacarra.

Jarvis made birdies on the third, fourth and fifth holes in a row, and added another birdie on the eighth. He dropped a shot on the ninth and completed the front nine in 33. On the 12th hole he hit a superb approach shot from the rough, then holed a 32-foot birdie putt to go five under. He closed out the round with a birdie from seven feet on the final hole.

France's Frederic Lacroix finished with a 67. Shin, the leader of the Korean Tour standings, made a birdie on the last hole and completed his round with a 66. Ryan Fox also stood out with his first-day performance.

Jarvis said his putting dipped in the middle of the season, that he began working with a new putting coach, and that his hard work is starting to pay off. The golfer, who has had a breakthrough season, won his first DP World Tour title at the Kenya Open in February.
