Huybrechts lost 3–0 to James Wade in the first round of the 2017 World Championship. At the fifth UK Open Qualifier he beat Gary Anderson, Terry Jenkins and Ian White all 6–5 in successive rounds and then threw the first nine-dart finish of his career during a 6–4 win over Darren Webster. Huybrechts reached the final by eliminating Michael Smith 6–5, but lost 6–3 to Simon Whitlock. Ronny briefly held the highest televised average of a Belgian player when he averaged 115.62 in the second round of the World Cup against Greece. However, a day later in the quarter-finals Kim averaged 121.97 against Singapore and the brothers went on to reach their third semi-final in a row, but were unable to win either of their singles matches against the Welsh team of Gerwyn Price and Mark Webster.
