Watson reeled off a low final round (63), which included a homeward nine of 30, and when he completed his round 40 minutes ahead of Casey who was then playing the 15th hole he led by one.
The finishing stretch at the TPC River Highlands provides both opportunity and danger and unfortunately for Casey, who had led by four heading into the final round, it would be the latter.
Unable to birdie the reachable par 4 15th he then pulled his tee shot long and left at the par 3 16th and the resultant bogey would mean that he needed birdies at the final two holes to catch Watson.
The Englishman found the water from the tee at the 17th however and he would eventually finish in a share of second.
Watson’s season just keeps getting better. After winning first and Riviera, he would then go on to win again at the WGC Dell Technologies Match Play and so this win moves him to 3rd on the FedEx Cup table and to 13th in the World Ranking, his best standing in eighteen months.
Watson has performed below his best in events over the last month or so but a return to a golf course on which he won his first PGA Tour title in 2010 and won again in 2016 inspired him to yet another great week in Hartford.
A downwind pitch from 77 yards at the par 4 18th (see below) was typical of the much vaunted Bubba Watson artistry, described by his caddy as one of the best shots he had seen his boss hit and given the shot-maker Watson can so often be that was quite a statement.
Jason Day led the Australians when he finished in a share of 12th which is his best finish in four starts in the event but, after starting the day in a share of 6th and a birdie at his opening hole, the round became a roller coaster.
Day slipped to 3 over for the day through 13 holes but brought it home strong with four birdies in his last five holes including a pitch in birdie at the last.
Matt Jones finished in 19th position after contending early in the event, completing his second best finish in 11 starts this season, while New Zealander Danny Lee also had a good week when he finished tied for 15th and after two consecutive missed cuts it was quite an improvement.
The PGA Tour now heads to Potomac in Maryland for the Quicken Loans National where Tiger Woods will be in action.
