Viktor Hovland moved one shot clear at the top of the leaderboard at the Tiger Woods-hosted Hero World Challenge in the Bahamas.

The European Ryder Cup player was in a share for the lead following the first round, and added a two-under 70 on day two to sit top at the half-way stage.

The Norwegian enjoys a one-shot lead over a quartet of Americans sharing second place - Scottie Scheffler, Xander Schauffele, Collin Morikawa and Cameron Young are all four under heading into the weekend.

The event is an unofficial PGA Tour tournament benefiting host Woods' foundation and Hovland, ranked number 12 in the world, who won last year's Hero World Challenge at 18 under for the week feels that the course is playing much more difficult this year in the wind.

"You're grinding on three-footers," said Hovland. "It's windy and it's grainy, and the greens are fast so it's not like you can just ram the putts in, you've gotto actually kind of die the putts in and that's when the wind can hit it a little bit harder."

Scheffler could replace Rory McIlroy as world No 1 with a win this week.

"I haven't really been No 2 for a while, so I feel like if I continue to play great and win some events I'll get back there, but it's not going to be something that I'll keep in the front of my mind," Scheffler said.

"It's not something I think about when I'm practicing, it's not something that occupies a lot of my thoughts. It's nice to be No 1."

Shane Lowry is in a tie for 19th in the 20-man field, shooting a five-over 77 to go with his opening round of 74.

The 2019 Open champion's round fell apart on the fifth and sixth holes, where he posted double bogey followed by a triple bogey eight.
