Ratchayothin Yotharuck (, born 13 December 1995 in Nakhon Nayok, Thailand) is a Thai former professional snooker player. Yotharuck has been playing snooker since he was 10 years old and represented Thailand in several international events together with Boonrayit Kiatkul and Noppon Saengkham. In 2013 he received a two-year wildcard for the Main Tour as an Asian Confederation of Billiard Sports nomination, after Asian champion Saleh Mohammad declined his place.
Having missed the first few events of the 2013âÂÂ14 season, Yotharuck made his debut at the Rotterdam Open, where he lost 4âÂÂ1 to Mitchell Travis in pre-qualifying. Yotharuck would lose all three of his first round matches in the ranking events, with the exception coming at the Indian Open. There he caused an upset by defeating former world champion Graeme Dott 4âÂÂ2 in qualifying and went on to beat his famous compatriot James Wattana 4âÂÂ3 at the venue, before being whitewashed in the last 32 match by Mike Dunn. He finished his debut season ranked world number 111.
Yotharuck lost nine of his ten matches during the 2014âÂÂ15 season and has not played in an event since December 2014. He lost his place on the tour at the end of the season as he was the world number 110.
