Four-time major winner Rory McIlroy roared back into contention at the French Open on Friday, sinking six birdies in a 5-under round of 66 to join a five-way share of the lead.

The Northern Irishman could have taken the overall lead at the Le Golf National course — which is hosting the 2018 Ryder Cup — but a poor tee shot on the 18th hole led to a bogey.

South Korea's Wang Jeung-hun matched McIlroy's 66, while Thongchai Jaidee of Thailand — who was one stroke behind overnight leader Lucas Bjerregaard of Denmark — posted a 1-under 70 for a share of the lead. The other co-leaders, Mikko Ilonen of Finland and South African Brandon Stone, had 68s.

Bjerregaard is three shots behind after four bogeys in a 74.
