Evans also played in the semifinal against Australia, losing both of his rubbers, and was a substitute for the Final against Belgium, with Great Britain winning the Davis Cup in 2015, the nation's first success in the tournament for 79 years.

[33] In September, Evans, the British No 5, made his debut as part of the Great Britain Davis Cup squad for the Europe/Africa Zone Group I relegation playoff against Poland, along with Andy Murray, Joshua Goodall, James Ward, Ross Hutchins and Ken Skupski.

In March, Evans was called to the Davis Cup team in the Europe/Africa Zone Group II tie vs Lithuania, in Vilnius, with James Ward, Ken Skupski and Colin Fleming.

After failing to qualify for The Championships, Evans moved away from Birmingham to train at the Nottingham Tennis Centre, where he would be coached by Mark Taylor[8] and Leighton Alfred.

[13] In December, the Lawn Tennis Association announced cuts to its financial support for some of Britain's underperforming players from 43 to 30, after raising the standards it requires them to meet.

[48] The following month, Evans entered qualifying for the PBZ Zagreb Indoors in Croatia, winning his three qualification matches before ultimately losing in three sets to Guillermo García López in the opening round of the main draw.

Soon after the Belgium tie, Evans arrived at the National Tennis Centre, to discover that his LTA coach, Julien Hoferlin had been assigned to Oliver Golding, the former US Open junior champion, instead.

[56] Evans was now unable to afford foreign travel,[57] so he spent the next 12 months playing in Britain and Ireland, at ITF Futures level, as well as taking in one Challenger tournament towards the latter stages of the year.

[60][62] With Great Britain trailing 2–0 to Russia, the GB doubles pairing of Colin Fleming and Jonny Marray reduced the deficit a day later, before James Ward levelled the tie at 2–2 after beating Tursunov in five sets.

[68] He then defeated Australian-born Brit Brydan Klein in straight sets in the second round,[69] before losing to the eventual champion, Australian Matthew Ebden in the quarter-finals.

Evans received a wild card into the Wimbledon qualifiers, where he lost in the first round to Spain's Daniel Muñoz de la Nava.

The 23-year-old reached a career-high ranking of 149, becoming British No 2,[75] and consequently, Evans was picked as Britain's second singles player in the Davis Cup World Group play-off against Croatia in Umag on clay.

Evans beat Jan Hájek and Michael Berrer in the first two rounds to make his first-ever quarterfinal at ATP World Tour level.

[89] However, since May, Evans returned to some kind of form, reeling off 29 wins from 33 matches, with four Futures titles, Egypt, Frinton, Felixstowe & Nottingham,[90][91][92][93] Roehampton finalist[94] and a run to the semis of a Challenger in Vancouver,[95] where he beat Czech Radek Štěpánek along the way.

300, and the fact that Evans beat Australian Bernard Tomic in the 2013 US Open, led to his surprise recall to the Great Britain squad for the Davis Cup Semi-final against Australia.

Evans was not even among four contenders that GB team captain Leon Smith named for two singles berths just over a week previously, but was now picked ahead of the injured Kyle Edmund, who is 200 places above him in the rankings at 100, and the woefully out-of-form James Ward.

[100] With Belgium opting to stage the Davis Cup Final on an indoor clay court, Leon Smith chose to go with the British number two Edmund, now ranked 100.

He advanced to the main draw of the tournament for the first time in his career where he lost comfortably to 18th seed Feliciano López, winning only five games in three sets.

At the RBC Tennis Championships of Dallas in February, Evans was beaten by Kyle Edmund[102] in the first all-British Challenger final since 2005, when Alex Bogdanovic beat Mark Hilton.

[124] He was the first English born player to reach a singles final there in more than 11 years (Tim Henman being the last in 2006) but lost the match in straight sets.

[126] Evans returned from his drugs ban on 28 April 2018, having only started training again two months earlier, defeating compatriot Edward Corrie in the first round of qualifying in an ATP Challenger Tour event in Glasgow.

[134] Evans defeated seventh seed Andrey Rublev in the quarterfinals at the 2020 Dubai Tennis Championships,[135] but lost in the last four to Stefanos Tsitsipas in straight sets.

[140] At the beginning of April, Evans reached his first Masters 1000 final with compatriot Neal Skupski at the Miami Open, losing to Mate Pavić and Nikola Mektić.

[145] In the same tournament, partnering again with Neal Skupski, he reached his second Masters 1000 doubles final within two weeks, losing again to 2nd seeds Mate Pavić and Nikola Mektić.

He won all of his matches in the group stage, with singles wins against Germany's Jan-Lennard Struff, Canada's Denis Shapovalov, and the United States' John Isner.

He also won his two doubles matches where he paired with Jamie Murray to win against Germans Kevin Krawietz and Alexander Zverev, as well as Americans John Isner and Taylor Fritz.

[173] At the same tournament, partnering with John Peers, Evans also reached the doubles final but lost to Wesley Koolhof and Neal Skupski in a deciding champions tiebreak.

[174] Seeded 20th at the US Open, Evans defeated Jiří Veselý[175] and James Duckworth,[176] before losing in the third round to Marin Čilić in a four set match lasting four hours.

[191] Evans' season got back on track in August when he defeated Grégoire Barrère,[192] Alexander Shevchenko,[193] Frances Tiafoe,[194] Grigor Dimitrov[195] and Dutchman Tallon Griekspoor to win the ATP Tour 500 Citi Open in Washington DC.

[209] In 2014, the management company Lagardere Unlimited's sports agent, Stuart Duguid, said of his charge Evans: 'British tennis fans are desperate for another top player to get behind in addition to Murray.
