At the 2014 Six-red World Championship Lertsattayathorn defeated defending champion Mark Davis in the last 16 before being defeated 7–2 eventual winner Stephen Maguire in the semi-final. In 2016 Lertsattayathorn entered the Asian Snooker Championship in Doha as the 13th seed. Lertsattayathorn went on to reach the final and defeated Mohammed Shehab 8–2 to win the championship, as a result he was given a two-year card on the professional World Snooker Tour for the 2016–17 and 2017–18. At the 2016 English Open, Lertsattayathorn beat compatriot Boonyarit Keattikun 4–3 and Michael White 4–1. In the third round he was 3–2 up on Ricky Walden, but then lost the final two frames.
