Casper Ruud ended Frenchman Gael Monfils's run at Indian Wells with a marathon 3-6 7-6(3) 6-4 victory and will face Tommy Paul in the quarters after the American brought lucky loser Luca Nardi back down to earth with a straight-sets win on Wednesday.

After struggling to put winners past the athletic Monfils in the opening set the ninth seeded Norwegian became more aggressive in a tight second set and rolled through the tiebreak.
