Britain's Jamie Burdekin teamed up with American world number one David Wagner to win his first British Open Wheelchair Tennis Championships quad doubles title.
They beat Australia's Dylan Alcott and Lucas Sithole of South Africa 6-0 6-1.
It was the second Super Series doubles crown of Burdekin's career.
In the men's singles, top seed Shingo Kunieda of Japan beat British world number three Gordon Reid 6-1 6-3 to win his fifth British Open title.
Team GB's London 2012 Paralympic bronze medal-winning pairing of Lucy Shuker and Jordanne Whiley were beaten in the women's doubles decider in Nottingham.
Whiley was looking for her second major triumph on home soil this month after winning Wimbledon with Yui Kamiji, but Japan's number one partnered Aniek van Koot to win Sunday's final 7-5 6-4.
Just a day earlier Kamiji beat Dutch world number two Van Koot to win the women's singles crown.
Meanwhile, Britain's world number three Andy Lapthorne was denied his first British Open quad title by Australia's former Paralympic basketball gold medallist Dylan Alcott, who prevailed 7-5 6-1 on Saturday.
Alcott, a former leading junior wheelchair tennis player, only picked up a racquet again 12 months ago after focusing on basketball, collecting a gold medal with the Australian Rollers at the 2008 Beijing Paralympic Games and silver at London 2012.
The British Open is one of six events to have Super Series status, the highest tier of tournament on the Wheelchair Tennis Tour, outside of the Grand Slams.
