Australian Adam Scott ended a two-year title drought by shooting rounds of 66 and 67 to win the rain-hit Texas Open at TPC San Antonio.
Scott, who was 1-under-par for the tournament after his first three holes of the day, in which 36 holes were played, won his first title since the 2008 Byron Nelson Championship with a 14-under total of 274 for a one-shot victory over Sweden's Fredrik Jacobson.
"Everything's coming together," said Scott, who told reporters that a recent putting tip from American veteran Dave Stockton helped him overcome his struggles.
"I've been really good with the putter the last two weeks. It's nice to see putts going in and rolling at the hole. It makes golf a lot more fun."
It was the seventh US PGA Tour victory for the 29-year-old, who ended his dry spell on a course designed by compatriot Greg Norman.
Fellow Australian Aaron Baddeley finished in a tie for third, two shots behind Scott.
Jacobson, seeking his first victory in the United States, needed to birdie the par-five finishing hole to force a play-off but his 20-foot putt from the fringe came up short and curled away to the right as he completed a 70 for 275.
"I was hitting the ball beautiful all 36 holes," said the Swede, who fired a 65 in his third round to surge into contention.
"I was hitting fairways and greens and getting good looks at it. If anything wasn't working for me to put it away, it was the putter, unfortunately."
