Glamorgan County Cricket Club have regularly used St Helen's as an outground since 1921. The ground has staged two One Day Internationals: England against New Zealand in 1973, and a 1983 World Cup match between Pakistan and Sri Lanka. St. Helen's was the location of Sir Garfield Sobers's six sixes in a single over in first-class cricket, the maximum possible runs in a single over, and the first time it had been done.
