Norfolk beat the world numbers two and three on his way to the final
Peter Norfolk missed out on ending the season as world number one quad singles player despite winning the end-of-year Wheelchair Masters title in Amsterdam.
The Briton beat American David Wagner 6-3 7-6 (7-4) in the final for his third Masters title since 2006.
But he finished second behind Wagner in the rankings by just eight points.
Meanwhile, Dutch wheelchair tennis star Esther Vergeer took her remarkable run past 400 consecutive victories in winning the women's event.
Vergeer, who is unbeaten at the tournament since her debut in 1998, brought up the landmark by beating compatriot Jiske Griffioen 6-3 6-0 and then triumphed 6-2 6-1 against Daniela Di Toro in the final to extend her overall record to 610 wins against 25 losses.
While Vergeer added a 103rd consecutive title, Norfolk was also able to reflect on another successful week in which he beat both Wagner and Sweden's Johan Andersson, who finished third in the rankings.
Tennis Foundation National Programme coach Stuart Wilkinson said of the 49-year-old: "Peter stayed mentally tough all week. It was a great effort and much deserved."
Elsewhere, Kevin Simpson retained his men's singles title at the Beit Halochem tournament in Israel, giving the Scot his third ITF Futures titles since September.
After a first-round bye, top seed Simpson won all three of his matches against Israeli opposition in straight sets, clinching the title with a narrow 7-6 (7-3), 6-4 victory over second seed Asaaf Stokol to maintain his ranking on the fringes of the world's top 40.
Simpson is now set to end his season on the 2010 NEC Wheelchair Tennis Tour at next month's Prague Cup Czech Indoor event.
