Billy Horschel has had just enough left in the tank to win the World Golf Championships Match Play with plenty of help from Scottie Scheffler in a sloppy end to the longest week in golf.
Horschel made only one birdie, chipping in from 40 feet on the fifth hole, to win the championship match 2 and 1.
Although he didn't find much to admire about his golf Sunday, he left the big mistakes to the 24-year-old Scheffler.
Horschel, who had never reached the weekend in four previous appearances at this WGC, 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 wasn't pretty," Horschel said.
"It was one of those days where I didn't play very good.
"I was just grinding it out."
It ended a great run for tournament debutant Scheffler, a Texas graduate who beat three former Match Play champions and two top-10 players this week.
"No one in front of them. Green reading books, lining up the lines on the ball. Really annoying me. And Matchplay is the fastest form of golf. Something has to be done #slowplay." – Colin Montgomerie
After leading 1-up after the second hole, Scheffler struggled but somehow managed to stay in the match until a missed 10-foot birdie putt on the 17th sealed the result.
"I just wasn't able to make any birdies this afternoon," Scheffler said.
The wind in Austin played havoc on the final day, with gusts raging through the trees in the morning and still causing problems in the afternoon.
While the conditions were tough, they did not prevent Colin Montgomerie lamenting the "ridiculous" pace of play from Horschel and Scheffler.
The slow pace of play was criticised by Sky Sports commentator Ewen Murray and eight-time European No.1 Montgomerie commented on Twitter: "100% agree. Pace of play ridiculous.
"No one in front of them. Green reading books, lining up the lines on the ball. Really annoying me. And Matchplay is the fastest form of golf. Something has to be done #slowplay.
In response to an image of both players and their caddies consulting their yardage books, Montgomerie added: "All four have their yardage books out. They've played the hole with practice 9 times this week. Stood there for two minutes doing nothing! Slow play needs to be penalised @SkySportsGolf @ewenmurray77 #slowplayruiningthegame."
Matt Kuchar won the consolation match 2 and 1 over Victor Perez of France.
Kuchar fell one win short of tying Tiger Woods' record with a fourth appearance in the championship match, losing 1-up to Scheffler in the semi-finals.
Horschel accounted for an error-prone Perez 3 and 2 in their last-four battle.
