AUSTIN, Texas — Billy Horschel had just enough left in the tank to win the Dell Technologies Match Play on Sunday with plenty of help from Scottie Scheffler in a sloppy end to the longest week in golf.

Horschel made only one birdie in the championship match, chipping in from 40 feet on the fifth hole, and left the big mistakes to the 24-year-old Scheffler in winning 2 and 1.

Horschel, who had never reached the weekend in four previous appearances at this World Golf Championship, won six out of the seven matches over 122 holes he played at Austin Country Club. He won for the sixth time on the PGA Tour, and his fifth individual title.

“It was one of those days where I didn’t play very good,” Horschel said, still able to smile because of the outcome. “I was just grinding it out.”

It ended a great run for Scheffler, a Texas graduate who had to beat three former Match Play champions and two players from the top 10 in the world to reach the championship match.

He had the support of the Austin crowd that occasionally shouted out, “Hook ‘em,” and Scheffler obliged.
