Fifth seed Juan Martin del Potro brushed aside John Isner 6-4, 6-4, 6-4 to reach the French Open quarter-finals 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.
