Anderson survived three match darts versus John Bowles in the second round of the 2013 World Championship to win in a deciding set, but was then comfortably beaten by Raymond van Barneveld 0–4 in 33 minutes as he missed a total of 23 darts at doubles. Because the ranking system works as a two-year rolling list based on prize money earned, Anderson lost the £100,000 from reaching the 2011 World Championship final and dropped to world number 11 after the tournament. Anderson partnered Robert Thornton for the third time at the World Cup of Darts and they were shocked by Spain 4–5 in the last 16. He threw a nine-dart finish in the third UK Open Qualifier during a first round win over Josh Payne, but lost in the following round 5–6 to Michael van Gerwen.
