Stricker made it count on the second play-off hole
Steve Stricker clinched victory at the Crowne Plaza Invitational following a three-way sudden death play-off.
Stricker won with a birdie at the second extra hole after finishing tied at 17 under with fellow American Steve Marino and Tim Clark of South Africa.
England's Paul Casey finished with a round of 66 to take fifth, two back.
Compatriot Ian Poulter shot 68 to end on 12 under, while Luke Donald was a two shots back after a level-par round of 70 at Colonial.
Another English pair, Justin Rose and Brian Davis, ended tied 34th on six under.
Clark was unfortunate that his approach to the 17th struck the flagstick before bouncing back from the cup from where he two-putted for par.
The Arizona-based player had looked set to clinch his maiden title on the US circuit until his misfortune on the second play-off hole.
"I can't take anything positive from today," the 33-year-old said. "I have a lot of work to do when it comes to closing out golf tournaments."
Marino's victory hopes effectively ended when he pulled his tee shot behind trees in the left rough and then pulled up short of the green with his second shot before making bogey.
"Obviously it's disappointing," Marino said. "But I'm playing well right now and I'm excited about playing golf and feel good about my game."
The trio had finished the 72 regulation holes on 17-under-par 263, overnight leader Clark bogeying the last for an even 70, while both Marino and Stricker closed with 68s.
Clark had a golden opportunity to end the tournament at the first extra hole but narrowly missed his birdie attempt from seven feet.
Stricker, who had chipped in from behind the green to birdie the par-four 17th in regulation, was delighted to birdie the same hole to triumph for the first time since the 2007 Barclays Classic.
Former world number three Stricker said: "Finally I was able to chip one in here and make birdie. It feels really good.
"I feel fortunate, I've been on the other end a couple times this year where you feel going to win and end up losing. This feels very good."
