Dustin Johnson went the last three hours over 13 holes without hitting from the fairway and still managed to hang on to the lead after two rounds at the Tour Championship.
Johnson could at least see his entire golf ball from the first cut on the par-5 18th at East Lake, setting up a two-putt birdie for an even-par 70 and a one-shot lead lead over Sungjae Im.
Australia's Cameron Smith fired his second consecutive 68 but is nine shots behind Johnson in a tie for 17th.
Smith's fellow countryman Marc Leishman struggled with a five-over 75 to drop 17 places after a promising opening round 66.
The big picture going into the final two rounds is all about opportunity.
As well as Johnson has been playing - two runner-up finishes and an 11-shot victory in his last three starts - there was a chance he could have started with that two-shot lead and created some big separation.
Instead, nine players are separated by five shots heading for the finish.
Im, the budding star from South Korea whose game had gone lukewarm coming out of the three-month shutdown, birdied three of his last four holes for a 64 and will be in the final group with Johnson.
Xander Schauffele, who won the Tour Championship as a rookie in 2017, ran off three straight birdies late in his round for a 65 and was two shots behind.
Another big move came from PGA champion Collin Morikawa, whose 66 put him in range.
Johnson has rounds of 67-70, and along with starting at 10 under because of his No. 1 seed, was at 13-under par.
He hit only two fairways - the first hole and the fifth, where both times he made par.
He still managed a birdie on No. 8 when he chipped in from 40 feet and the final hole, one of the two par 5s at East Lake.
Rory McIlroy, who managed only two birdies, lost ground at the end with a shot that laser cameras estimated at 85 feet, which didn't account for how far it sunk to the bottom of the lake.
He tried to reach the 18th green from the thick rough just through the fairway, and it topped out into the water.
That led to bogey and a 71.
