MONTREAL — Patrick Cantlay couldn't have hit the putt — he might not have seen the hole — without lights from a video board and the headlamps from golf carts surrounding the 18th green in the final match of the longest day at the Presidents Cup.
And then he delivered another ''Patty Ice'' moment that might have been enough to turn the lights out on the International team Saturday.
Scottie Scheffler delivered big moments late in both of his matches, and Cantlay's putt from just inside 17 feet in the dark gave the Americans another win, another point, moving them one session closer to another Presidents Cup victory.
''Huge putt,'' U.S. captain Jim Furyk said. ''If you had to hand select someone to hit a big putt on your team, I think Pat would come to a lot of people's minds.''
They won the fourballs and foursomes sessions by a 3-1 margin. Cantlay and Xander Schauffele won on the 18th over Tom Kim and Si Wood Kim, the high-charged South Korean duo, that gave the Americans an 11-7 lead at Royal Montreal.
''Xander helped me read it,'' Cantlay said of his match winner in near darkness. ''It was like a cup out with some speed, and a putt like that will make me sleep a little better tonight.''
It was Si Woo Kim who chipped in from deep rough below the 16th green that gave his side hope, and he leaned his cheek into his hands the ''Good Night'' gesture made famous from Stephen Curry in the Paris Olympics this summer.
That turned out to be an early call.
