Canada's Conners 4 shots back, Cantlay has 1-shot lead entering final round at BMW Championship

Patrick Cantlay and Xander Schauffele went from being teammates to close friends and now seem to be inseparable on the PGA Tour, so the final round of the BMW Championship might have the feel of one of their countless practice rounds.

Except for the stakes.

Cantlay holed out from 106 yards in the fairway on the par-5 14th and had a 6-under 65 despite twice missing 3-foot par putts. That gave him a one-shot lead over Schauffele and Scott Stallings going into Sunday in the second FedEx Cup playoff event.

Corey Conners of Listowel, Ont., is the top Canadian after three rounds at eight under and tied for eighth. Taylor Pendrith of Richmond Hill, Ont., is tied for 10th at seven under, while Adam Hadwin of Abbotsford, B.C., is tied for 38th at two under.

WATCH | Conners shoots 70, remains in hunt at BMW Championship:

Schauffele had an eagle early in the round with an approach to 5 feet on the par-5 third hole and he played bogey-free for a 67.

Sunday will be the sixth time in eight FedEx Cup playoff events they have played together, and it will be the second time this year they have played in the final group. Schauffele led by one at the Travelers Championship and shot 68 to win. Cantlay had a 76.

They also won the Zurich Classic as partners.

The typical practice round is match play of some variety, winner-take-all. This one could determine who goes to the Tour Championship as the No. 1 seed and starts the chase for he FedEx Cup with a two-shot advantage.

That depends on Masters champion Scotti Scheffler, who joined Adam Scott two shots behind.

Cantlay, who was 12-under 201, is trying to become the first back-to-back winner of the BMW Championship since it became part of the FedEx Cup playoffs in 2007.
