Del Potro reaches first French Open quarterfinal in six years
Fifth seed Juan Martin del Potro brushed aside John Isner 6-4, 6-4, 6-4 to reach the French Open quarterfinals for the first time since 2012 on Monday.
The Argentinian produced an impressive display on Court Suzanne Lenglen, firing 25 winners and making just 14 unforced errors against the American ninth seed.
The 29-year-old Del Potro was knocked out in the third round at Roland Garros last year after missing the previous four tournaments in Paris through injury.
He will face either fellow former US Open champion and third seed Marin Cilic or fiery Italian Fabio Fognini in the last eight.
