World number one Scottie Scheffler enjoyed a two-shot lead after the second round of the Hero World Challenge as he looks to defend the title. 

The 28-year-old American made eight birdies in a bogey-free round to finish on 13 under at the Albany Golf Club in the Bahamas.

Scheffler was three shots back of Cameron Young after the first round of the event that has a field of 20 players and is hosted by Tiger Woods. 

"[I was] just trying to keep my foot down on the pedal," said Scheffler.

"It was good. I did a lot of good things. The front nine was really nice and then the back nine I felt like I did some good things as well."

Justin Thomas and Akshay Bhatia are joint-second on 11 under, with Keegan Bradley two shots back and sitting in fourth place.

"I didn't feel like I had to grind on the majority of my birdie putts, a lot of them were tap-ins or whatnot," Thomas said. 

"If I can just iron or wedge it just a little closer to the hole and get some putts to go in, I feel like I've got a really good round out there this weekend."

Sepp Straka and Im Sung-jae are tied for fifth place after shooting 68s, while Young, who was the leader after the opening day, slipped down to share 10th place.
