Although he did not play in the ATCO World Series final because of a hamstring injury sustained at the Qatar World Open, Ashour retained the world number one ranking at the first world series event in 2013, the J.P. Morgan Tournament of Champions. With his right leg heavily strapped, Ashour made it to the final, where he recovered from a 2-0 deficit against Gaultier to stage an unlikely comeback. By claiming another TOC title after his previous one in 2011, he became only the third player to win the prestigious PSA series title thrice since Peter Nicol did it in 2004. Ashour added two PSA world tour titles to his resume within two weeks. He beat his long running rivals, Willstrop and Matthew, in the semi-final and final of the North American Open in Richmond, Virginia, claiming his second North American Open title. Twelve days later, Ashour won his 30th tour title by taking the Kuwait PSA Cup (formerly the Kuwait Open). He defeated defending champion Willstrop in the final, and extended his run of consecutive major PSA titles to seven. In May, Ashour clinched his first British Open championship, becoming the first Egyptian to win the tournament since Abou Taleb in 1966. He also extended his unbeaten run to 41 matches, with his last previous loss taking place at the 2012 British Open final in London, exactly a year previously. After the summer break, Ashour won his ninth PSA World Tour title in a row and extended his unbeaten tour run to 45 matches by taking down defending champion Grégory Gaultier in the Netsuite Open final.
