Ryan is a right-arm fast-medium bowler and right-hand batsman.
After catching the eye of Hampshire's Director of Cricket, Giles White, at a minor counties match for Devon at Finchampstead, Stevenson was offered a trial at the Ageas Bowl mid-way through the 2015 season.
The right-armer, who was born in Torquay, immediately impressed the Hants coaching staff and finished with figures of 4-20 in his third Second XI match for Hants against the Kent Second XI.
Initially signing a deal until the end of the 2015 season, with White stating that Ryan had shown ‘a lot of talent and potential’, the 23-year old made his first-team debut in Hampshire’s impressive Championship win over Durham at the Emirates ICG.
A useful knock of 30 in that match proved that Stevenson is more than capable with the bat alongside his promising ability with the ball.
Ryan went on to feature in Hampshire’s last two matches of the 2015 campaign as the club avoided relegation from Championship Division One and, in September, the paceman signed a new two year contract keeping him at the Ageas Bowl until the end of the 2017 season.
In 2016, Stevenson made his List-A debut against Essex Eagles in the Royal London One Day Cup at the Ageas Bowl, and took just four balls to claim his first wicket in the format. Ryan had a frustrating 2017 campaign after suffering a long-term back injury, playing just once, that coming back in April against Cardiff MCCU.
