Berrington played for Scotland in the 2018 Cricket World Cup Qualifier. He scored a half-century in Scotland's opening-day upset win against Afghanistan as part of a national record 208-run third-wicket partnership with Calum MacLeod, and he scored 47 runs in Scotland's thrilling tie with Zimbabwe. In Scotland's final match, with Scotland needing to beat the West Indies to qualify for the 2019 Cricket World Cup, Berrington was controversially dismissed leg before wicket. Replays showed that the ball hit Berrington outside the line of off stump, meaning he should not have been given out. As the tournament was not making use of the Umpire Decision Review System to save on costs, Scotland were unable to challenge the call. Scotland lost by just four runs under the Duckworth–Lewis–Stern method, but had they lost one less wicket they would have won.
