Alcott claimed two Grand Slam singles titles in 2015 by beating David Wagner at both the Australian Open and US Open, which helped him surpass the American at the summit of the rankings.

The 25-year-old also picked up three Super Series crowns, at the Sydney International Open, the Japan Open and the BNP Paribas Open de France, as well as two ITF 1 Series titles and two ITF 2 Series to end with a total of nine.

Wagner finished as the world number one in quad doubles for the 12th successive year after he clinched eight titles, six of them with fellow American Nick Taylor.

The duo reigned supreme at the US Open and the UNIQLO Wheelchair Doubles Masters to ensure Wagner kept hold of his position at the top of the rankings.

Britain’s Gordon Reid also enjoyed a stellar year as he topped the men’s doubles rankings for the first time thanks to sealing two Grand Slam victories and the UNIQLO Wheelchair Doubles Masters, which he won alongside Frenchman Michael Jeremiasz.

Reid partnered Japan’s Shingo Kunieda, the number one in men’s singles, to his maiden Grand Slam success at the French Open, which he followed by winning the US Open with Stephane Houdet of France.

Kunieda, named as the men’s wheelchair World Champion by the International Tennis Federation for the seventh time earlier this week, swept the Grand Slam events this year to take his career singles tally at the majors to 20.

The Netherlands’ Jiske Griffioen, the world number one player in women’s singles, also ended a fruitful 2015 on top of the doubles rankings following another impressive year in which she secured victories at the Australian Open and US Open with partner and compatriot Aniek van Koot.

The Dutch duo couldn’t be separated on points but Griffioen, the women’s singles ITF World Champion, claimed the number one spot by virtue of competing at 11 events compared to Van Koot’s 12.
