Thailand overcame Myanmar 3-0 in the final of the Southeast Asian (SEA) Games football tournament on Monday to consolidate their regional champion position.
Midfielder Tanaboon Kesarat, who helped the men's full national team win the Southeast Asian championships in December, struck the opening goal in the 51st minute after Myanmar failed to clear a corner.
Chananan Pombubpha, who had been guilty of wasting a number of chances beforehand, made the game safe when he was put clear by playmaker Chanathip Songkrasin in the 63rd with substitute Pinyo Inpinit wrapping up the scoring with 12 minutes remaining.
The victory was the Thai's 15th football gold in the biennial multi-sports event and 10th in the last 12 editions.
Head coach Choketawee Promrut told reporters it was the best Thai under-23 winning side to win the SEA Games title and said a halftime tactical switch won gold.
"In the first half, Myanmar was compact, very good. In the dressing room (we said that) we must play wide. It worked."
Earlier, Vietnam crushed Indonesia 5-0 to win the bronze medal.
Three players share the topscorers position, including Bombuppha of Thailand, Aung Sithu of Myanmar and Vo Huy Toan of Vietnam, each with five goals.
