In the 2015 World Cup, Lam and MacKenzie caused a couple of shocks. First they defeated Wales' Mark Webster and Jamie Lewis 5–3. Lam then beat Ireland's William O'Connor 4–1, but MacKenzie lost 4–3 to Connie Finnan meaning a doubles match was needed to settle the tie which Hong Kong won 4–3 to reach the quarter-finals. However, the Scottish number two seeds of Gary Anderson and Peter Wright proved a step too far as they won both their singles matches 4–2 to eliminate Hong Kong.
