Two-time Paralympic wheelchair tennis champion Peter Norfolk powered to his sixth Florida Open quad singles title on Sunday.
The world number two beat unseeded Israeli player Noam Gershony 6-2 6-3.
Outsider Gershony had a shock win over world number one David Wagner earlier in the tournament.
It brings Norfolk's tally of major singles titles at either Grand Slam or Super Series events to 19.
After a solid opening set Norfolk made the first breakthrough in the second set, holding serve to move 4-2 ahead.
He then won the last two games of the match to seal his sixth title in Boca Raton since 2004, though it was his first since 2009.
"It was a surprising week, playing players with some new and different styles," said Norfolk. "I played a solid tactical final against Noam, who was in his first Super Series final. My backhand returns were very penetrating and I'm very happy to have regained the title."
But Norfolk's hopes of a third Florida Open doubles title ended when he and fellow Briton John Parfitt were beaten 6-4 6-1 by American top seeds Wagner and Nick Taylor.
