After two rounds of the BMW Championship at Wilmington Country Club it is Adam Scott alone atop the leaderboard at eight under, but some of the sport's biggest stars are breathing down his neck.

Scott shot the second-best score of the opening round with a six-under 65, and he was in position to put a gap on the field as he was sitting at 10 under with two holes to play before a costly double bogey on the 17th saw him post a 69 on his second trip around the course.

An incredibly strong four-man group is one stroke back at seven under, consisting of American trio Jordan Spieth, Scottie Scheffler and Cameron Young along with Canada's Corey Conners.

Only two players – Kurt Kitayama and Keith Mitchell (both 66s) – shot better than Scheffler, Conners and Spieth's 67 on Friday as they marched up the leaderboard.

Also shooting a 67 was Australia's Cam Davis, helping him to six under in a tie for sixth, where is joined by Rory McIlroy, Xander Schauffele, Patrick Cantlay and Scott Stallings in a loaded top-10.

More serious contenders are at five under, including major champions Shane Lowry and Hideki Matsuyama, with Lowry projected to sneak into the top-30 of the FedEx Cup rankings and earn a berth into the Tour Championship if he can hold on.

Also at five under is Kitayama, who was Friday's best putter according to Data Golf's strokes gained stats, with his 3.75 strokes gained leading second-placed Matsuyama (3.31 strokes gained).

First-round leader Keegan Bradley shot a 74 to fall down to four under, where he is joined by Tyrrell Hatton and Lee Kyoung-hoon, while Will Zalatoris, Collin Morikawa and Justin Thomas are a further stroke back in the logjam at three under. 

Rising talent Sahith Theegala is at two under, Max Homa is at one under and the pairing of Matt Fitzpatrick and Viktor Hovland are the top names at even par.

Jon Rahm enters the weekend at one over, given there is no cut for this tournament, and despite being Friday's best driver (1.84 strokes gained, McIlroy second at 1.49), he was the third-worst in approach shots (2.45 strokes lost) and second-worst in the around-the-green category (1.96 strokes lost).
