Dolan was outplayed by Gary Anderson in the World Championship in a 4–1 defeat. He won the fourth UK Open Qualifier by beating Jamie Lewis 6–1. A favourable draw saw Dolan beat Steve Beaton, Nigel Heydon and Aden Kirk to reach the quarter-finals of the UK Open for the first time, where he lost 10–4 to Terry Jenkins. His second title of the season and fourth in sixth months came at the fifth Players Championship where he averaged 103.66 in whitewashing Michael Smith 6–0 in the final. In June, Dolan and Mansell beat Peter Wright and Robert Thornton from Scotland in the quarter-finals of the World Cup. In the semis, Dolan edged world number one Michael van Gerwen 4–3, but Mansell lost 4–0 to Van Barneveld to send the match into a deciding doubles game in which the Dutch pair averaged an incredible 117.88 to progress with a 4–0 whitewash. Dolan won the 16th Players Championship with a 6–2 victory over Anderson at the Citywest Hotel in Dublin, the same venue where he reached the final and threw a nine-dart finish in the 2011 World Grand Prix. A day later, Anderson exacted revenge by knocking Dolan out of the first round of the World Grand Prix 2–0 in sets. He missed doubles in successive legs at 8–7 up against Van Gerwen in the second round of the European Championship and was eliminated 10–8. Dolan earned a spot in the Grand Slam through the qualifier, but lost each of his group games against Wright, Simon Whitlock and Michael Smith to finish bottom of the table.
