During his near decade with Hampshire, Pothas has stood in as county captain when captains such as Shane Warne, Shaun Udal and Dimitri Mascarenhas were unavailable. However, with then incumbent captain Dimitri Mascarenhas injured for the 2010 season following an injury picked up in the Indian Premier League, Pothas was selected to captain the team on a more long term season basis. Mid-season, he developed a cartilage defect in his right knee which ruled him out of the remainder of the season. He was replaced as captain by Dominic Cork and as wicket-keeper by Michael Bates. He added more honours during this season by being a member of Hampshire's 2010 Friends Provident t20 winning squad, having captained and played in the group stages of the competition.
