Norway's Viktor Hovland continued his hot play Saturday with an 8-under-par 64 to tie the lowest round score of his young career, giving him the third-round lead at the Puerto Rico Open in Rio Grande.

The 22-year-old Hovland, a rookie on the PGA Tour this season, birdied on three of his final four holes to top the leaderboard after 54 holes for the first time of his career with an 18-under 198.

Looking to become the first rookie to win on tour this season, Hovland was bogey-free at Grand Reserve Country Club with eight birdies -- including six on his last 10 holes after shooting just 2 under through the first eight holes.
