Juan Martin del Potro ended John Isner’s good run of form at the Rogers Cup in Montreal on Monday with a straight sets victory in the first round.
The American had won eight matches without dropping a set as he claimed back-to-back titles at the recent Newport and Atlanta Opens – the 11th and 12th titles of his career.
But Del Potro just needed two breaks to upset Isner, both coming at 5-5 as he won 7-5, 7-5 to advance to the second round of the ATP Masters 1000 tournament.
The Argentine kept his cool against the big-serving Isner, who fired down 24 aces, winning the crucial break in the second set at the third attempt after a marathon eight-minute game.
Straight shooting, straight sets. ?

He now faces the winner of the match between Canadian wildcard Denis Shapovalov and Brazil’s Rogerio Dutra Silva.
In other late Monday action, David Ferrer of Spain overcame Britain’s Kyle Edmund after two hours and 26 minutes to claim a 6-7(5), 6-4, 6-3 win to set up a second round tie against either American 15th seed Jack Sock or France’s Pierre-Hugues Herbert.
France’s Adrian Mannarino defeated Russia’s Daniil Medvedev 6-3, 6-1 and will now play home favourite and sixth seed Milos Raonic in the next round.
Del Potro’s compatriot Diego Schwartzman will face third seed Dominic Thiem after a win over giant American Reilly Opelka.
