What followed was a penalty drop, a shot to the rough, another short of the green and a quadruple-bogey 8 that most likely ended his chances. Toms is the only one to shoot his snowman in the final round.
The final two rounds of this year's PGA Championship should present players with a very different challenge to the first two.
It did not develop cruelty; it was born that way. 17 and 18 and is tied for second at 6 under. He is 11 in both strokes gained/ off the tee and around the green, and 12 in strokes gained/ approach the green.
It's hard enough to make an eagle at Quail Hollow. But the last two weeks his putting has looked stronger with only 54 total putts thus far in the PGA Championship. Being a major championship venue simply raised the punishment level.
He was in lofty company, one strone ahead of a fading Jason Day and England's Paul Casey. His top finish at a major is tied for 12th at the 2015 U.S. Open at Chambers Bay in Washington.
Kevin Kisner withstood a wavering back nine to keep the lead, shooting a 1-over-par 72 in the third round of the PGA Championship on Saturday at Quail Hollow Club.
Stroud said he had "1,400 text messages, 55 voicemails and probably another 100 emails". I'm going to play the best I can and let's just ride this out. I think the length is causing it.
One more day. One more round. 14-16, only to be stuck with a double-bogey on the final hole.
STAT OF THE DAY: This is the fourth time 2010 British Open victor Louis Oosthuizen has been fourth or better through 54 holes at a major. He had a tiresome finish, which on this day allowed him to make up ground. Not to worry; he'll have a replacement in his bag Sunday.
Kisner lamented squandering the chance to eliminate more rivals. But he double bogeyed 18.
"It's a dream to win a major championship", said Kisner, who has never finished in the top 10 of a major.
Matsuyama is very much a confidence player and there was every likelihood that he would carry over this quality of play from OH to North Carolina. "Now I'm in a dogfight tomorrow, and I have to be prepared for that".
Assuming Kisner or none of his competitors run away with the tournament, the Green Mile will decide this 99th PGA Championship. They are among the toughest finishing holes in golf.
Kisner had eight pars on the front nine Saturday to go with his birdie on the par-5 seventh hole. It's the balance of aggressiveness versus caution. Mickelson hasn't won since the British Open in 2013, and this ends a streak of three consecutive years when he at least had a runner-up finish in a major.
The idea persisted after he birdied 14, 15 and16 to get to two under for the day and into position to have his first sub-par round of the tournament.
Or that he would be playing on a different hole. "You know, I've been waiting on this a long time".
"Sometimes, I get a little too aggressive, like on 18".
The South African, who began the round three shots off the pace, is attended by a physio as he walks down the fairway, but continues playing solidly. Anything less ... well, game on. He said anyone who broke 70 was going great. The guys up there now are proven winners, they don't get nervous.
