<p>A day after replacing Rafael Nadal as world number two, Murray delivered a gritty performance to wear down the towering Argentine in two hours, 42 minutes under a broiling sun. <br /><br />It was Murray's fifth win of the season and he become the first Briton in 128 years to lift the Canadian title. <br /><br />The victory completed a perfect start to the North American hardcourt season for the 22-year-old Scotsman, who was returning to action after his semifinal loss to Andy Roddick at Wimbledon. <br /><br />Del Potro, coming off victory in Washington last week and riding a 10-match winning steak, took a tight opening set in a tie-break 7-4 -- the only set surrendered by Murray all week. Leading 6-5 in the second with Murray about to serve, Del Potro called a medical time-out to have his back massaged, drawing an angry scowl from the unhappy the Briton, who protested the move slamming his towel on a chair. <br /><br />The time-out, however, appeared to ignite Murray, who went on to win 36 of the next 48 points. Murray moved in for the kill, recording two early breaks to go 4-0 up before finishing the contest with an emphatic ace. <br /><br />Jankovic wins<br /><br />A rejuvenated Jelena Jankovic upset world number one Dinara Safina 6-4, 6-2 to win the Cincinnati Open. The fifth-seeded Serb took advantage of an error-strewn display from the Russian to clinch her second title of the year. <br /><br />Jankovic had come through a two-hour, 46-minute encounter with Elena Dementieva in the semifinals but she looked the fresher and an early break was enough to give her the first set. <br /><br />Safina had been the most consistent player throughout the week but her feet looked heavy and Jankovic took full advantage. <br /></p>
