Batting at three, Harris made only nine as Australia reduced the home side to 178 all our, and then hit 417 runs. Leeward Islands were routed for 208 in the second innings, however Harris enjoyed success, scoring the second highest total of his team's innings, 44. He then faced the Windward Islands later that year on 25 November at Roseau, where he scored 62. The following year, on 27 January, he scored 41 and 52 against Jamaica, and on 9 February was dismissed for one but took two catches in a rain-interrupted match against Barbados. Matches against British Guiana and Trinidad and Tobago followed through 1966, yielding scores of 61, 13, zero and 39 from the top order. 1965–66 was Harris' most eventful season thus far in his career, and he ended it with 276 runs from five matches at 34.50. 1967 saw three more matches for Leeward Islands against Barbados, Jamaica and the Windward Islands. In the first match, on 9 February, Harris faced Barbados in Warner Park, Basseterre, and scored 18 and 10. He also bowled two deliveries before Barbados declared for 406. Against Jamaica he scored 91 – then a career best – and 15, and against Windward Islands on 27 March at Sturge Park, in the now abandoned Plymouth, Montserrat, where he scored 33. He then faced the MCC for a second time on 15 February 1968, also in Plymouth. He hit 48 and 18 in a match largely dominated by a knock of 165 from Geoffrey Boycott. With his efforts in the 1968 season, he broke the Leeward Islands' batting record. On 17 January 1969, he scored zero and 30 against Barbados, and on 12 February scored 17 and 12, and took once wicket for 14 runs against Guyana. Harris then played four successive matches in early 1970, the first against Windward Islands on 16 January at Warner Park. This was followed by matches against Barbados on 13 February; Trinidad and Tobago on 6 March; and Jamaica on 14 March. The season overall netted Harris 207 runs at 20.70, with one half-century of 72, from the five matches. 1971, his final year in first-class cricket, began with a match against the Windward Islands on 14 January at Warner Park. Harris, batting at five, scored his maiden – and only – century. His knock of 105 took Leeward to 315 all out, having bowled Windward Islands
