In an exact reverse of their 2013 clash, Beaton was knocked out 3–0 by Kyle Anderson in the first round of the 2015 World Championship. He lost 9–5 to Peter Wright in the third round of the 2015 UK Open and the first round of both the 2015 World Matchplay (10–4 to Gary Anderson) and the 2015 World Grand Prix (2–1 in sets to Justin Pipe). Despite only winning one of his three group fixtures, Beaton qualified for the knockout stage of the Grand Slam on leg difference. He averaged almost 100 in the second round, but only had five attempts at a double as Michael van Gerwen averaged 109 in defeating Beaton 10–2.
