Mann won a two-year card on the professional World Snooker Tour for the 2014–15 and 2015–16 seasons in June 2014 after winning the 2014 EBSA European Snooker Championships, beating John Whitty 7–2 in the final. He missed the first two ranking tournaments of 2014–15 season as this win came after the qualifying rounds of those events. He picked up his first win on the tour by edging experienced player Peter Lines 6–5 in qualifying for the International Championship. He came through a wildcard round match 6–1 against Niu Zhuang and then made a 142 break during a 6–5 win over Wang Zepeng. In Mann's deepest run in a ranking event to date he lost 6–4 to Michael White in the last 32. He was knocked out in the first round of both the UK Championship and Welsh Open.&lt;ref name="2014/15"&gt;&lt;/ref&gt; Mann saw off Alfie Burden 10–4 in World Championship qualifying and won three frames in a row, after Gerard Greene had come from 4–0 down to trail 7–6, to beat him 10–6. He required one more win to reach the biggest tournament in snooker, but lost 10–6 to Alan McManus. Mann was the world number 88 at the end of his first season on tour.
