Australia captain Tim Paine has played down the significance of his team's poor use of the decision review system despite the glaring discrepancy between his success rate and that of his opposing number Joe Root.

The Australians have reviewed their DRS protocols but do not believe it is a major issue despite paying a heavy price for a lapse of judgment in the final moments of their loss at Headingley.

The need to use DRS more prudently is increased this week by the appointments of Kumar Dharmasena and Marais Erasmus, who have vastly superior referral numbers to Headingley pair Joel Wilson and Chris Gaffaney.

Since the system was introduced in November 2009, Dharmasena ranks eighth of 29 with 75.74 per cent of his referred decisions upheld while Erasmus is 14th with 73.3 per cent, according to BBC Test Match Special statistician Andrew Samson. The pair are well ahead of Gaffaney (24th, 67.83 per cent) and Wilson (27th, 61.53 per cent).
