Born in the Zimbabwean capital Harare, Rouse moved to England with his family when he was ten years old, living at Farleigh Wallop near Basingstoke.

Rouse made his First Class cricket debut for Hampshire in 2013 against Kent,[6] also appearing once for the county in a one-day game against the touring Bangladesh A team.

[12] Following his release by Gloucestershire, Rouse qualified as a personal trainer, a move he later suggested had allowed him to play cricket "with a bit more freedom" and provided a "plan-B".

His season was cut short following two finger dislocations during Kent's County Championship match against Glamorgan towards the end of June, a game in which Rouse made his maiden first-class half century.

[25] Rouse continued to keep wicket at the start of the 2017 County Championship season, taking 13 catches and making a new first-class highest score of 95 not out in the first block of matches before signing a new contract with Kent in late April.

[27][28] Rouse retired from professional cricket in July 2020, at the start of the 2020 season which had been delayed due to the COVID-19 pandemic,[29][30][31] having made 84 senior appearances in his career.
