Vincent van der Voort in the following round. He nearly qualified for the
2014 World Grand Prix, for which a place in the semi-finals was needed, but was beaten 6–3 in the quarter-finals by
Andy Hamilton. Price's impressive start to his darting career continued by reaching his first semi-final at the 19th Players Championship where he lost 6–3 to
Ian White.
2015 The £12,750 he earned in Pro Tour events during 2014 saw him finish 39th on the Order of Merit to claim the eighth of sixteen places that were on offer to non-qualified players for the
2015 World Championship. Price missed one dart at tops to level at one set all against
Peter Wright in the first round and was beaten 3–0. His successful year saw him start 2015 ranked world number 59. Price was knocked out of the preliminary round of the

Ian White 9–8 in the second round of the
Players Championship Finals, but went on to lose 10–9.
2016 Andrew Gilding won each set in the first round of the
2016 World Championship by three legs to one in beating Price 3–0. In February at the fifth
UK Open Qualifier, Price defeated
Mark Webster 6–1 and
Mensur Suljović 6–3 to reach his first PDC final, but he was denied the title by world number one

Jamie Caven. After knocking out
Kim Huybrechts 10–8 at the
World Matchplay, Price would face
Adrian Lewis in the second round for the second year in a row. Before the match Lewis stated that Price's win over him 12 months ago was lucky and that Price was a "big mouth who's never won anything and never will win anything". The pre-match tension seemed to affect both players as both averaged in the 80s with Lewis prevailing 11–5. Price lost 2–0 in the first round of the
World Grand Prix to
Benito van de Pas, and 10–2 to
Michael van Gerwen in the second round of the

Alan Norris. Norris missed three darts to take the 19th leg and Price finished 100 with two double tops, before breaking throw in the next to win 11–9. In his first major final he was 7–2 down to
Peter Wright, before reducing his deficit to 8–6. However, Price then lost the last three legs to be beaten 11–6. Victories over Finland, Ireland and Russia helped Price and
Mark Webster into the semi-finals of the
World Cup of Darts. A pair of 4–2 wins over the Belgian team of

Raymond van Barneveld as they went down 3–1 to the Dutch.
2018 In the
2018 World Championship, Price won in the first round of the World Championship for the first time when he beat
Ted Evetts 3–0. In the second round Price beat

Michael van Gerwen. Van Gerwen won the first two sets but then Price won seven legs in a row to go two sets all and ahead in the fifth set. Price had set darts in the fifth set, but failed to take them. Van Gerwen won the fifth and sixth set which meant Price lost the match 2–4.

2018 Premier League Darts tournament. Despite good draws against world number 2
Peter Wright and

Mensur Suljović 16–12 in the semi-finals, and against

seed due to his performances on the Pro Tour. He was narrowly beaten 11–9 by Michael van Gerwen after missing four darts to take the match into a deciding leg.

Glen Durrant, but he was eventually defeated, in a heated encounter 6–3 by
Peter Wright, who went on to win the title. In March Price reached the
