Career
Richardson joined the Personal Digital Cellular Pro Tour in 2011, after winning a tour card on the first day of Q School. He reached his first Pro Tour final in Gladbeck on 23 October 2011, losing 6–2 to Colin Osborne. Richardson stated afterwards that the victory was "an absolute dream".
He then faced Belgian Kim Huybrechts in the second round, but couldn"t find the form he showed in the first round as he was beaten 4–1.
In April, he earned a place in the Austrian Darts Open in Vienna by defeating Stuart Kellett in the United Kingdom qualifier. He received a bye through the first round after Adrian Lewis pulled out of the event and then beat Peter Wright 6–3.
He saw off Michael van Gerwen in round three, before losing 6–3 to Dave Chisnall in the quarter-finals. He also reached the German Darts Masters and defeated Wright 6–3 once more in the first round in Stuttgart.
Richardson played Wes Newton in round two and lost 6–4.
He threatened to cause a major shock for the second successive year by taking the opening set of his first round match against Andy Hamilton, but went on to lose 3–1 as he missed three darts to extend the match to a deciding set. His best result of 2013 was in the fifth Players Championship where he was edged out 6–5 by Peter Wright in the last 16. He failed to qualify for any of the European Tour events during 2014 and could only record a best of three last 32 defeats in his other events.
Richardson lost the £6,000 from his ranking he earned at the World Championships two years ago and dropped to world number 102, outside the top 64 who remain in the Personal Digital Cellular. He played in Q School and only reached the last 32 once during the four days to fail short of earning a new tour card, but he still had entry into United Kingdom Open and European Tour qualifiers as well as the Challenge Tour in 2015.
Richardson reached the third round of the United Kingdom Open for the first time by seeing off Johnny Haines and Dean Stewart, but then lost 9–4 to Nathan Aspinall. He reached the semi-finals of the seventh Challenge Tour event and was defeated 5–1 by Scott Dale.
