[7] Lam made his debut in the World Cup of Darts in June as he represented Hong Kong with Scott MacKenzie.

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.

[10] 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.

[12] Lam won the Malaysian Open by beating Mark Jumin in the final and the same opponent defeated him in the semi-finals of the South Asian Qualifier for the 2017 World Championship.

[13][14] Lam claimed a two-year PDC Tour Card for 2017 and 2018 when he beat José de Sousa 5–2 in the last round on the second day of Q School and said he would continue to play a mix of events in Asia and Britain.
