Lewis made his List A debut for Jamaica in October 2011, playing against the Leeward Islands during the 2011–12 Regional Super50.[1] He opened the batting with Chris Gayle on debut, and top-scored for Jamaica with 28 runs as his team won by seven wickets.[2] Lewis played another four Regional Super50 matches during the 2011–12 season, including Jamaica's win over Trinidad and Tobago in the tournament final.[1] He also played three matches in the 2011–12 Caribbean Twenty20.[3] He returned to Jamaica's squad for the 2013–14 Regional Super50, but played only a single match, the semi-final against Trinidad and Tobago in which his team were bowled out for just 49 runs.[1] For the 2014 Caribbean Premier League season, Lewis signed with the Red Steel, as the second-youngest member of the squad (after Nicholas Pooran). He played two matches, against the Antigua Hawksbills and the Guyana Amazon Warriors, and opened the batting with Irishman Kevin O'Brien in both, but scored just five runs and was subsequently dropped.[3]
