Terry Jenkins made a nervy start to the 2011 World Championship, narrowly beating Bradford born Joe Cullen in the first round 3 sets to 2. He initially led 2–0 and 1–0 in the third set against the darts before Cullen won 6 of the next 9 legs. Jenkins then beat Steve Brown 4–1 and followed this with a very convincing 4–0 victory over Mark Walsh. Reaching the quarter finals of the tournament Jenkins beat Wes Newton completing his first televised 170 checkout in the process to progress to the semi finals. He ended the tournament at the semi-final stage with a 6–2 loss to Gary Anderson. Following this Terry qualified as a wildcard for the 888.com Premier League Darts and opened his Premier League campaign with an 8–6 victory over Raymond van Barneveld. In week 2 he lost to Gary Anderson 8–4 throwing just over a 91 average, with Gary throwing a 102.21 average. In week 3 he lost to Phil Taylor while throwing a poor average of 85.61. He continued his poor form in an 8–1 defeat to Simon Whitlock in the fourth week of the 2011 Premier League of Darts.
