[9] On 9 October 2016, Hatton secured his first victory on the European Tour as he cruised to the Alfred Dunhill Links Championship title at St Andrews.

He finished on 23 under par, four shots clear of South African Richard Sterne and England's Ross Fisher.

His on-course temperament was called into question, with veteran European Tour pro Gary Evans telling him to 'grow up'.

[11] Hatton responded a week later at the successful defence of his Alfred Dunhill Links Championship title by saying: 'Nobody's perfect'.

[15] In March 2020, Hatton won the Arnold Palmer Invitational by one stroke over Marc Leishman for his first PGA Tour victory.

[16] In October, Hatton won the European Tour's flagship event, BMW PGA Championship at Wentworth.

In September 2023, Hatton played on the European team in the 2023 Ryder Cup at Marco Simone Golf and Country Club in Guidonia, Rome, Italy.

The European team won 16.5–11.5 and Hatton went 3–0–1 including a win in his Sunday singles match against Brian Harman.
