Rory McIlroy’s remarkable summer continues – the Irishman is in contention for the BMW Championship in Indiana.

The USPGA winner is a shot behind Phil Mickelson and Vijay Singh as he looks to win two Sundays in a row.

McIlroy and England’s Lee Westwood are tied on 15 under par in Carmel after Mickelson set the way with a course record 64.

McIlroy hit a third round 69 but said he had not been at his best.

The 23-year-old said: “It wasn’t the greatest ball-striking round out there that I’ve ever had, but I somehow managed to scrape it around in 69 and still in with a chance.

“As badly as I did hit it out there, I’m still happy with my position going into tomorrow.”
