London: England opener Jason Roy will try to follow the batting example of Australia's David Warner when he makes his Test debut against Ireland at Lord's later this week. Warner defied conventional wisdom by showing how an opening batsman who had first made his name in white-ball cricket could then make a success of his Test career.

Roy, 29, is no red-ball novice, having played for county champions Surrey, but mainly as a middle order batsman, and he has nine first-class hundreds to his credit. He comes into the Test set-up ahead of an Ashes series fresh from scoring 443 runs as an opener in England's triumphant World Cup campaign.
