– Whether it was the South African juggernaut of Branden Grace and Louis Oosthuizen, the inspired play of Bae Sang-moon in front of his home crowd or a format change that reduced the number of matches, the Presidents Cup is truly up for grabs for the first time in 10 years.

That's all the International team ever wanted.

Grace delivered two big shots in the gathering darkness, and the South African duo went 4-0 in team matches. Bae and Hideki Matsuyama teamed for nine birdies in 11 holes for the biggest rout of the week. And the International team played the Americans to a draw in a double session Saturday, leaving them one point behind at 9-8.

Considering how lopsided the Presidents Cup has been, it felt like a lead.

"We need to win this," Oosthuizen said. "This is huge for us.."

World No. 1 Jordan Spieth made two clutch putts in morning foursomes to cap off the biggest comeback at the Jack Nicklaus Golf Club Korea, and he made eight birdies in 14 holes in a U.S. four-balls victory in the afternoon.

Not since the matches were tied going into Sunday in 2005 has the Presidents Cup featured a final day of drama.

"This is what we all came here for — for it to be exciting tomorrow," International captain Nick Price said.

Grace and Oosthuizen were all square with Bubba Watson and J.B. Holmes, and it was clear their four-balls match would set the tone for the final round. Grace chipped in for birdie from left of the 16th green.

To holes later, Grace watched his 3-wood shot disappear into the gloaming and had no idea what happened until he heard a burst of cheers coming from the grandstands. The ball cleared the bunker and settled on the edge of the green.

"Just remarkable to pull a shot off like that," Grace said.
