NORTON, Mass. – Kevin Chappell did just about everything right Saturday, even when making his lone bogey, on his way to a 7-under 64 that gave him a one-shot lead in the Deutsche Bank Championship and another chance at his first PGA Tour victory.

Chappell pitched in for eagle on No. 7 and made a 35-foot birdie putt on the next hole. Even better was the 15-foot bogey putt on the 13th hole, and his great escape from a bad shot when trying to lay up on the par-5 18th.

He was at 11-under 131, one shot ahead of PGA champion Jimmy Walker (64) and Paul Casey (66).

Dustin Johnson was poised to join Chappell in the lead until an approach into the woods led to double bogey on the par-5 closing hole.

David Hearn of Brantford, Ont., stayed in contention with his second-straight round of 68. He’s at 6 under and in a tie for 13th. Adam Hadwin of Abbotsford, B.C., shot a 72 and is 2 over for the event.
