Jack Draper blown away in straight sets by US star Reilly Opelka at Miami Open

• ‘Servebot’ fires down 25 aces to beat British player

• Katie Boulter into third round after win over Tauson

Jack Draper suffered a tough defeat in his opening match at the Miami Open as he could do little to ­neutralise a dominant serving performance from Reilly Opelka, who fired down 25 aces in two sets en route to a 7-6(3), 7-6(0) win.

The defeat is a difficult setback for Draper, the 25th seed, as he ­continues to navigate the early stages of his return to competition from a bone bruise injury that forced him off the tour for seven months. Miami is just the third ATP tournament of his comeback.
