Mathews began his international career in late 2008 with ambitions of becoming a genuine allrounder, but has since given primacy to his batting (to diminish his workload and avoid injuries), and effectively plays as a specialist batsman in the Test side. However, for the balance of the team, he still plays as a batting allrounder in the limited overs cricket. A more than useful strike rate of 84.06 has made him a damaging prospect in the final overs of the Sri Lankan innings.
