Victory means Lapthorne is now a two-time Doubles Masters champion, having also won the title in 2010 partnering Britain's Peter Norfolk, and ensured Rio 2016 Paralympian Cotterill one of the biggest successes of his career.

With the quad doubles starting as a four-way round-robin competition, Cotterill and Lapthorne had had to retire from their pool match against the Americans counterparts earlier in the week when the latter was unwell.

They bounced back strongly in the final, however, to snatch the first set 7-5 before Taylor and Wagner gained firm control of the match and took the second 6-1.

As in the opening set, Cotterill and Lapthorne managed an early break in the decider, only for Taylor and Wagner to level proceedings after eight games.

The second seeds held out though to seal a 7-5, 1-6, 6-4 victory.

In the men’s doubles final, Rio 2016 gold medallists Stephane Houdet and Nicolas Peifer of France justified their top seeding by overcoming Argentina’s Gustavo Fernandez and Belgium’s Joachim Gerard 2-6, 6-3, 7-5.

The win earned Houdet his fifth Doubles Masters men’s title with his fifth different partner as he and Peifer battled back from a set behind.

Gerard had won the Doubles Masters title in 2014, partnering Houdet, and a second title in Mission Viejo looked on the cards as he and Fernandez built on a 3-0 lead to take the opening set.

The French pair dominated the second half of the second set, however, to force a decider.

Houdet and Peifer went on to break serve at the start of the deciding set, only for Fernandez and Gerard to win the next three games.

The momentum swung from one team to the other in the closing stages but, with Fernandez visibly upset by a line call that went against him and Gerard, Houdet and Peifer kept up the pressure to triumph.

They have become the second all-French partnership to win the men’s Doubles Masters title after Houdet partnered Michael Jeremiasz to victory in 2007.

The other final on the last day of competition also went to a deciding set as first-time partnership Diede de Groot of The Netherlands and Lucy Shuker of Britain clinched the women’s doubles crown with a 6-3, 4-6, 6-4 victory over Britain’s Louise Hunt and the United States' Dana Mathewson.

Rio 2016 women’s doubles silver medallist De Groot and bronze medallist Shuker had never played together in competition before arriving in Mission Viejo, but they showed little sign of that in the early stages of final and took the opening set by winning the last three games.

Hunt and Mathewson started and finished the second set the stronger and then put together a run of four consecutive games to move a break up in the deciding set.

The momentum shifted though back to the top seeds, who wrapped up a narrow win.
