Roland-Jones is a tall pace bowler who immediately marked himself as a player for the future when he burst onto the county scene in 2010.
He picked up 38 wickets at an average of 19.60 in his debut first-class season.
The seamer saw his progress disrupted by injury during the following year but still played an important role in helping Middlesex win promotion to Division One of the LV= County Championship.
Having represented MCC in Abu Dhabi at the beginning of that campaign, Roland-Jones ended the summer as one of 13 players named as potential England Performance Programme representatives.
The next season he was Middlesex’s leading championship wicket-taker with 61 scalps as they came third in the top flight and he was rewarded with inclusion in the aforementioned England programme to tour India.
He continued to take regular wickets and in 2014 his 43 championship wickets - which included a career-best 12-105 against Northamptonshire - were crucial in keeping Middlesex up.
