Peter Norfolk battled to a second quad singles title at the Australian Wheelchair Tennis Open in Melbourne with a 6-2 6-3 win over David Wagner.
The Briton was broken by Wagner in a tense opening game but broke back and again at 4-1 on his way to the set.
The pair swapped breaks in the second as Norfolk struggled with his serve but he made the decisive break and served out on his first match point to win.
Norfolk adds the Australian title to the US Open crown he won in September.
The 47-year-old from Fleet, who had just returned from four months out with a shoulder injury, had defeated American Wagner again to claim the inaugural title at Flushing Meadows.
"I am absolutely delighted with my performance this week and to win my second Australian Open title," said Norfolk.
"It is an honour and a privilege to be intergrated into the Grand Slams, the tennis public appreciate it and I look forward to more of it having now won titles at two Grand Slams.
"It is an honour and a privilege to be intergrated into the Grand Slams, the tennis public appreciate it and I look forward to more of it "
"It is such a great feeling to lift the trophy, but I mustn't forget it doesn't happen without having Team Norfolk behind me - including my coach Jon and my wife Linda - pushing me on to get better and fitter, especially as I had four-five months off with injury last year.
"I'm very happy with this jet-propelled start to Paralympic year."
The singles victory helped Norfolk gain revenge for his doubles defeat to Wagner on Friday.
Wagner and his American partner Nick Taylor beat Norfolk and Canada's Sarah Hunter in a deciding championship tie-break.
The American players, who have only lost once as a doubles partnership since January 2004, triumphed 5-7 6-0 10-3.
Earlier in the tournament, British women's number one Lucy Shuker went out of the singles at the quarter-final stage and exited the women's doubles in the semi-final.
But Jamie Burdekin won the quad singles at the Queensland Open in Brisbane.
