Newton reached his second PDC major final in September's European Championship in Mülheim, Germany. He beat Tomas Seyler, Kevin Painter and then Andy Hamilton in the quarter-finals to face his room-mate Brendan Dolan in the semis. Newton produced a superb comeback to take five successive legs from 6–9 to down to triumph 11–9, before losing to Simon Whitlock 5–11 in the final. At the World Grand Prix, he was a dart away from exiting the tournament in the first round to Ronnie Baxter, but his opponent missed and Newton went on to win 2–1 in sets, before beating Ian White 3–1 in the last 16. He once again produced a comeback in his quarter-final against Paul Nicholson, as he took the match 3–2, despite being 0–2 down. In his semi-final against Michael van Gerwen, Newton was heavily out-scored in a 1–5 defeat. Newton qualified from Group 1 of the Championship League with a 6–3 victory against Adrian Lewis, in a group that contained the top eight players in the Order of Merit. However, he finished 7th in the Winners Group, winning just two of his seven matches. Newton topped Group G in the Grand Slam of Darts with wins over Martin Phillips, Wesley Harms and Terry Jenkins to face BDO player Christian Kist in the last 16. Newton trailed 3–7, but came back to tie the match at 9–9, before failing to hold his throw to claim the win. After all 33 ProTour events of 2012 had been played, Newton finished seventh on the Order of Merit to qualify for the Players Championship Finals where he lost to Gary Anderson 4–6 in the first round.
