Carmel, INDIANAPOLIS — Adam Scott is poised to strike the top of the leaderboard at the BMW Championship after posting a 4-under total through his opening 10 holes before the first round was suspended at Crooked Stick Golf Club on Thursday.

The world No.6 was gaining momentum on the field and was three shots back of American leader Roberto Castro’s 7-under par 65 as darkness halted play during the opening round of the FedEx Cup playoffs’ third instalment in Indianapolis. The first round will resume at 8am Friday, local time.

Scott rattled off three birdies and an eagle on a sizzling front nine before dropping a shot at the beginning of the turn. The Queenslander leads the Aussie charge after compatriot Jason Day slumped to a disappointing 1-over par 73.

The world No.1’s round started ominously when the first tee-starter called him “Jordan Day” and although he laughed it off, the 2015 US PGA Champion failed to get his game off the ground.

Next best of the Aussies was Aaron Baddeley, continuing his recent return to form with a 1-under score through eight holes. Marc Leishman, the only other Australian to have progressed to the third playoffs event courtesy of making the top-70 players at last week’s Deutsche Bank Championship, was a shot further back at even par through 16 holes.
