American Tim Herron ended seven years without a victory after a play-off with Sweden's Richard Johnson.

Herron took the Bank of America Colonial tournament in Fort Worth, Texas, with a 10-foot birdie putt on the second extra hole after they had tied on the 12-under-par mark of 268.

Former European Tour winner Johnson, in his fourth season in the States and looking for his first win, had looked out of it when he three-putted the 16th for bogey.

But the Stockholm golfer, ranked only 174th in the world, then sank birdie putts of 28 and seven feet on the final two greens and drew level when Herron bogeyed the 16th as well.

Par putts of 12 and nine feet forced the tie and after the first play-off hole was shared in par fours they went back to the 17th and Johnson generously applauded his opponent after the winning birdie putt dropped.

It was still Johnson's best-ever performance in the States. His previous highest finish was third in the 2003 FedEx St Jude Classic.

He closed with a 67 to Herron's 68, while Australian Rod Pampling, on level terms with Herron until he double-bogeyed the 15th, finished two behind in third spot.

Herron, the world number 60, had had only one top-25 finish all season coming into the event.

"I wanted to go out and win this one," Herron said. "I was getting close for many years and, you know, I felt like if I just hang in there, but I think you really have to go out and get it.

"It's never easy. You got to keep plugging along, and I made a lot of great putts and that's what you have to do to win. I had some good breaks too."

Johnson said of his dramatic few closing holes: "When I three-putted 16 I thought I was out of it.

"My caddy just told me on 17, just hit it in the middle of the green, let's get in now. I said, I want to make one more birdie because you never know what happens. And I just happen to roll it in on 17.

"When I walked onto the green at 18 I had no idea what was going on behind me. I'm very pleased.

"I am really proud of what I did. It didn't happen for me this time - maybe next time."

England's Justin Rose finished in a tie for 45th after his second successive 71 left him one under.
