Hughes leads through 54 at RSM Classic

Updated: 

Canadian rookie Mackenzie Hughes maintained his lead after the penultimate round of the RSM Classic.

Hughes' advantage, however, was cut to one stroke following his two-under-par 68 on Saturday.

The 25-year-old teed off with a two-shot buffer but he posted his worst round of the PGA Tour tournament so far, while snapping his bogey-free streak at Sea Island.

Hughes finally dropped a shot at the 11th hole but he did birdie the 13th, 15th and 16th to stay atop the leaderboard at 16 under, just ahead of Camilo Villegas, Billy Horschel and Pan Cheng-tsung.

Villegas carded a blistering six-under-par 64 to surge into a share of second after the third round.

The Colombian finished strongly, ending the day with a flurry of four consecutive birdies.

Horschel was flawless as he posted a blemish-free five-under-65, while Pan had a third-round 67.

Chesson Hadley (67) is a stroke further back, while Patrick Rodgers (65), Charles Howell III (67) and Blayne Barber (68) are tied for sixth at 13 under.

Ollie Schniederjans (66), Henrik Norlander (66) and Stewart Cink (67) complete the top 10.
