The former British No.1 looks set to be challenging Evans for that spot in the not too distant future as he produced an excellent performance to defeat the fourth seeded young Canadian Felix Auger-Aliassime 6-4 6-4 to make the quarter finals of the Mexico Open.
The British No.2 started the match strongly breaking in the first game to take a lead and then wrapping it up inside 49 minutes.
In the first meeting between the two players, Edmund, ranked 44th in the world, compared to the Canadian’s ranking of 19, took the first set without having to face any break points.
Auger-Aliassime, last week Marseille finalist losing to Stefanos Tsitsipas, was unable to capitalise on his opportunities, winning neither of the two break points he gained in the second set.
Elsewhere, world number two Rafael Nadal, the top seed, remains on course for a third Mexico Open title after defeating Serb Miomir Kecmanovic 6-2 7-5. The Spaniard next plays South Korea’s Kwon Soon-woo in the last eight.
Surpisingly Alexander Zverev, the second seed, crashed out qualifier Tommy Paul of the US 6-3 6-4 but both Grigor Dimitrov and Stan Warinka, respectively the seventh and third seed, have come through to face each other for a place in the semis.
