Unfortunately for Chappell, his health was now blighted by recurring tonsillitis and he found it difficult to bat for long periods during the 1974–75 Ashes series. He was the backbone of Australia's sometimes inconsistent batting, scoring 608 runs at 55.3. At Sydney, where Australia won to reclaim the Ashes, Chappell dominated with 84 and 144, which he followed up with a century in a losing cause in the sixth Test at Melbourne. At Perth, he broke the world record for a fielder by snaring seven catches. Ironically, his grandfather Vic Richardson was one of several players who held the old record of six. Chappell reluctantly had his tonsils removed, but he quickly lost a lot of weight which affected his performance on the tour of England that followed. He played in the World Cup (for what proved to be the only time), then made only one good score (73* at Lords) in the four Ashes Tests that followed.
