Novak Djokovic avoided Ben Shelton, but Adrian Mannarino—who simply won’t go away—could be a test

Novak Djokovic vs. Adrian Mannarino

This 35-year-old Frenchman just won’t go away, no matter how hard his opponents try. With three five-set victories in three rounds, he’s knocked out veteran star Stan Wawrinka and rising star Ben Shelton.

Could he do it again, against Djokovic?

Djokovic hasn’t cruised to this point, dropping a set in his first two matches. But after a three-set win over Tomás Martín Etcheverry, the Serbian is feeling his rhythm, keeping his head down and locked in heading into week two.

The momentum Mannarino is carrying into this matchup will make him even harder to break down. Mannarino is prepared to go the distance to give world No. 1 a run for the title, but surely, if necessary, Djokovic is as well.
