He joined the Oxford golf team with Cyril Tolley, a good friend of his, and both were successful young golfers.

Wethered narrowly lost The Open Championship to Jock Hutchison in the 1921 edition of the tournament.

He followed this achievement with further successes: his driving began to improve and he won his first Amateur Championship in 1923 at Deal, Kent.

Furthermore, he was capped by England numerous times in competition against Scotland and in the Walker Cup against the United States, emerging victorious with regularity.

In singles competition he beat all-comers, losing only to American golfer Bobby Jones.

His first wife was Elizabeth, daughter of Lord Charles Cavendish-Bentinck (1868–1956), marriage dissolved in 1954.
