runs; Gibbs' final innings return of 8/38 was his best in a Test match. In 1963, West Indies toured England, and Gibbs had another highly successful series, taking 26 wickets at 21.30 including 5/59 and 6/98 in a ten-wicket triumph at Manchester. Further successful series followed: indeed, in eight successive series topped and tailed by the 1960–61 and 1968–69 tours to Australia, Gibbs never took fewer than 18 Test wickets and took five or more wickets in an innings on 12 occasions. In 1967, Gibbs played for Warwickshire in the English County Championship, for whom he would continue to appear each season until 1973, although his appearances in 1969 and 1973 were reduced because of his commitments with West Indies' tours of England. In 1970, after a winter spent with South Australia, he took a career-best 8/37 against Glamorgan, but by far his most successful season in England was 1971 in which Gibbs claimed 131 first-class wickets at only 18.89, with nine five-wicket hauls. This exceptional performance gained Gibbs a Wisden Cricketer of the Year award in the following year's Almanack. He has been retrospectively ranked by the ICC as the top bowler in Test cricket for five consecutive years starting from 1964. In 1973, at the age of almost 39, Gibbs made his One Day International debut against England at Leeds as part of the Prudential Trophy tournament, taking the wicket of England captain Mike Denness. He played only two further ODIs: the first again being against England two days later at the Oval (11–4–12–1 and the wicket of John Jameson), and a single outing against Sri Lanka at Manchester in the 1975 World Cup, in which he bowled just four overs without success. Gibbs' last Test matches were played on the tour of Australia in 1975–76. Although he played in all six Tests, and took 5/102 in the first innings of the first Test at Brisbane, his 16 wickets came at an average of over 40, the worst of his five series against these opponents. He passed the milestone of 300 Test victims at Perth by dismissing Gary Gilmour. His last Test match, and indeed his last appearance in senior cricket of any description, was at Melbourne, his 309th and final Test wicket being that – again – of Gilmour. He was, however, a very poor batsman, who never made a half-century in first-class cricket. After his retirement
