Huybrechts' run to the World Cup final saw him qualify for the Grand Slam of Darts where he beat 2012 BDO World Champion Christian Kist 5–3 in his opening group game. He then fought from 3–1 behind against two-time world champion Adrian Lewis to triumph 5–3 and qualify from his group with one game to spare. Huybrechts completed a hat-trick of group game wins by seeing off Richie George 5–3 and he played his brother Kim in the last 16, which saw them become the first brothers to play a televised darts match with Ronny losing 10–5.
