Robert MacIntyre closed with a 41-foot birdie putt to grab a four-stroke lead over top-ranked Scottie Scheffler after Saturday's third round of the US PGA Tour BMW Championship.

The 29-year-old Scotsman, runner-up to J.J. Spaun at June's US Open, fired a two-under par 68 to stand on 16-under 194 after 54 holes at Caves Valley in suburban Baltimore.

"The day was tough," MacIntyre said. "It wasn't the plain sailing of the first two days, but I thought I managed it well.

"It was steady. Holed some nice par putts, missed a couple of chances I felt I could have got, but the pins were absolutely brutal."

As for his electrifying final putt, MacIntyre said, ""Holing that putt is a massive boost going into tomorrow. That one shot is everything out here."
