Ben Martin 2-putted for par on the first playoff hole Monday to win the United Leasing Championship.
Martin, who closed with a 67 on Sunday, defeated Billy Hurley III, Ashley Hall and Joe Affrunti in Monday's playoff, which was delayed by more rain.
The Monday finish was needed after a four-hour weather delay on Sunday. It was the first Monday finish for the tour since 2006.
When play got underway Monday morning, Martin was the only player to find the 18th fairway off the tee. Hall and Hurley splashed their tee balls in the water and Affrunti was in the left rough.
"When I drew a number and saw it was No. 1, I was pretty pleased. It's such a tough drive because right is in the water and left is in the rough or the bunker," Martin said. "I was happy to get it out of the way and that probably did put a little pressure on them."
Hall dropped another ball in the water en route to a quadruple-bogey. Affrunti and Hurley were both forced to lay up, then Martin put the pressure on as he dropped his approach 15 feet from the hole. Hurley scrambled for a bogey, while Affrunti also made bogey after laying up from the rough.
Martin easily 2-putted for the win at Victoria National Golf Club.
"I'm sure all four of us sitting up there on the tee would have taken a four if they would have given it to us," Martin stated. It's a tough hole and four is always a good score. I didn't know if I would win it with a four, but I probably wasn't to going to lose it."
The playoff was needed because Hurley and Affrunti double-bogeyed the 17th hole on Sunday to fall into a share of the lead. They finished at 11-under 277.
Hall paced the leaders with a 6-under 66 in the final round, while Affrunti carded a 70 and Hurley shot even-par 72.
Adam Hadwin (71) finished in fifth at 9-under and Alex Cejka (71) captured sixth at minus-8.
It was a two-man race for most of the day Sunday between Hurley and Affrunti. Affrunti birdied three in a row from the third to pull within a stroke of Hurley just before play was halted to rain.
When the players returned to the course after a lengthy delay, Hurley regained some cushion with a birdie at the 10th. Affrunti, meanwhile, traded a bogey at the sixth with a birdie at the seventh before rolling in another birdie at the 12th, moving him to 12-under.
Affrunti made it two in a row with another gain at the 13th to meet Hurley atop the leaderboard. Affrunti briefly lost his share of the lead by dropping a shot at the 14th, but bounced right back with a birdie at the 15th.
After each player parred the 16th, the duo posted matching double bogeys at the par-4 17th to fall into a tie with Hall and Martin, who were already in the clubhouse at 11-under.
Hurley and Affrunti parred the 18th to force the playoff.
Hall had countered his lone bogey with seven birdies during his final round, while Martin bounced back from a bogey at the first with six birdies over his final 17 holes to move to 11-under.
