Shingo Kunieda (JPN) and Esther Vergeer (NED) made history on Sunday at the US Open, part of the NEC Wheelchair Tennis Tour, becoming the first players to win all four Super Series titles in the same year.
Meanwhile, David Wagner (USA) clinched a personal landmark, winning his first US Open Quad title to seal a clean sweep of all three Quad Singles Super Series titles available this season.
Top seed and defending champion Kunieda cemented his place as World No 1 with a stunning performance to defeat World No 2 Robin Ammerlaan (NED) 61 61 in the Men's Main Draw Singles final. Kunieda's victory over the Dutchman for the second successive year leaves Ammerlaan still looking for an elusive first US Open title after a string of appearances in the final in recent years.
Having also proved utterly dominant all week en route to the Women's Singles final Vergeer was gifted a seventh US Open title after second seed and World No 2 Sharon Walraven (NED) withdrew from Sunday's final with injury.
The Quad Singles final saw World No 1 Wagner clinch his debut title in San Diego after a close final against defending champion and World No 2 Peter Norfolk (GBR).
A high quality first set saw both players hit some spectacular winners as the set came down to a tie-break, which Wagner clinched 75. Both players continued to trade games in the second set until Wagner broke in the 11th game of the set, earning two match point opportunities on his next service game.
A week ago Wagner had seen Norfolk come back from match point down to clinch the Altanta Masters title in three sets, but this the time the American made the most of his opportunities and went on to seal a 76(5) 75 victory. Wagner's victory is his first over Norfolk in a three week period that had seen the Briton notch up three successive wins over the World No 1 in New York and Altanta. Wagner and Norfolk have now won three matches apiece in their six head-to-heads this season.
The last Main Draw final of the week to be decided was the Women's Doubles. Vergeer completed another tremendously sucessful tournament as she and Jiske Griffioen sealed a comprehensive title defence with a 60 60 win over second seeds Korie Homan and Maaike Smit in the all-Dutch final.
