CHASKA, Minn. — Leading: United States is up 9 1/2- 6 1/2.

Up Next: The Ryder Cup will be decided in the 12 singles matches Sunday. The U.S. needs 5 points to win the Cup, Europe needs 7 1/2 to retain it.

Big Afternoon: The U.S. team came through in the afternoon better ball sessions, winning three of four matches to build its lead.

Match of the Day: Sergio Garcia and Rafa Cabrera Bello were down from the second hole on and 4-down with six holes to play. They roared back for a tie in alternate shot.

Shot of the Day: A wedge by Patrick Reed that spun back into the hole on No. 6 in better ball to give himself and Jordan Spieth a lead they never gave up against Justin Rose and Henrik Stenson.

Uh-Oh: Lee Westwood missed a short putt on the 17th hole and an even shorter one on 18 as he and Danny Willett lost 1-up to Ryan Moore and J.B. Holmes in better ball.

Key Stat: In 49 holes over three matches, Rory McIlroy and Thomas Pieters have never trailed.

Notable: The last time the Ryder Cup was on U.S. soil, the Europeans came back from a 10-6 deficit on the final day to win in 2012 in Chicago.

Just as notable: European captain Darren Clarke picked his top players to go out first Sunday to try and regain momentum.
