Hovland thus wins $3.6 million, equivalent to around 35 million kronor.
It has been stressful, but absolutely incredible, says Hovland.
Darkness fell in Connecticut on Sunday, and the tiebreaker between top seeds Hovland and Scheffler had to be decided on Monday.
Then Hovland made a birdie putt, while Scheffler missed his and made par.
This is the fourth time Scheffler has finished second on the PGA Tour this year.
