Stewart Cink won the Travelers Championship in Cromwell, Connecticut, after a solid final 18 holes.
Entering the final round with a two-shot lead, Cink squandered the advantage before regaining it to win by one shot over 2007 champion Hunter Mahan and Tommy Armour III.
Cink carded a three-under-par 67 to finish at 18-under, having also won this tournament in 1997 when it was known as the Greater Hartford Open.
Overcoming a brief weather delay during the final round, Cink carded four birdies and a bogey.
The American endured his lone bogey at the par-four fourth hole, then was flawless the rest of the way as he collected the first prize of $1 million.
It was Cink's fifth career title and his first since 2004, who finished fifth last week at the US Open.
Brian Davis carded a final round of 66 to lift himself to 11 under and a share of 12th place. Fellow Englishman Justin Rose had a 67 to finish a stroke behind in a tie for 19th.
