World number one Scottie Scheffler saw his lead cut to four shots after fellow US players Collin Morikawa and Xander Schauffele closed the gap during a weather-disrupted second round at the Tour Championship.

The two-time major winner, who started the tournament at 10 under par thanks to his position as leader in the FedExCup standings, had a seven-stroke lead over his two rivals after the opening round following an impressive opening 65 in Atlanta.

Bidding for his first FedExCup title, Scheffler birdied two of his final three holes after a weather delay to card a second-round 66 and to take himself to 21 under par.

"I feel like my swing is in a good spot. I've hit it nice the last couple of days," Scheffler said.

"A lot of quality stuff out there, and yeah, in a good spot going into the weekend."

Morikawa is four back from Scheffler after hitting a 63, the best round of the day, to take sole possession of second place on the leaderboard.

The 27-year-old dropped only one shot on the 11th hole and finished his round with back-to-back birdies.

Xander Schauffele is one shot back from Morikawa, with whom he was tied after round one, and remains in the hunt for the £19m prize after a second-round 64.

Northern Ireland's Rory McIlroy is tied for 10th place on eight under par.
