Shingo Kunieda (JPN) and Peter Norfolk (GBR) won the Men's Main Draw Singles and Quad Singles finals on Sunday at the US Open, part of the NEC Wheelchair Tennis Tour, in San Diego.
After two three sets victories in his quarter-final and semi-final matches, fourth seed Kunieda defeated second seed Robin Ammerlaan (NED) in straight sets to win his second Super Series title after opening his Super Series account at this's Japan Open in May.
Sunday's victory has seen the 22-year-old Japanese star jump three places in the world rankings to become World No 1 by a narrow margin for the first time in his career.
While Kunieda was winning his first US Open title, Norfolk gained his fourth US Open Quad Singles crown in six years. However, Norfolk's win in Sunday's final was the most difficult in his four finals to date as the World No 1 had to come from a set down before overcoming defending champion and third seed Nick Taylor 46 64 63. Taylor had also been bidding to win his fourth US Open as both players have shared the San Diego title since the start of the century. In following up previous wins in 2001, 2003 and 2004 Norfolk collected the 11th Super Series title of his career and has won all three Quad Super Series events contested this year.
The last Main Draw final of the week saw top seeds Jiske Griffioen and Esther defeat third seeds Korie Homan and Maaike Smit 63 63 in an all-Dutch final.
