Australian tennis star Nick Kyrgios played through a groin injury to beat Marcos Baghdatis of Cyprus in the opening round of the Madrid Open on Monday.
Playing in his first match since the death of his grandfather, Kyrgios delivered 14 aces to cruise past Baghdatis 7-6 (7-1) 6-4 to advance in the clay-court tournament.
Nadal will have to get through Italian Fabio Fognini in the Round of 32 on Wednesday.
Nadal, seeking a third consecutive clay court title after capturing the Monte Carlo Masters and Barcelona Open, could not face Fognini on Tuesday due to an ear infection.
The last time they played it was Fognini who triumphed, blowing the Scot off the court at the Rome Masters in an impressive 6-2 6-2 win.
In that match he hit a total of 31 winners on his favoured surface of clay, winning the first set in a positively breezy 40 minutes.
Anderson, one of the tallest players around at 6ft 7in, had also required two long periods of treatment on his back.
He recovered to come through 4-6, 6-4, 2-6, 6-2, 6-1.
His fines then were ,000 for hurling his racket to the grass and ,500 for abusing an official and an obscene gesture at Kuznetsov.He made barely any errors and smashed a large number of winners past the World No 1.Most of those winners were off his mighty forehand, which is arguably his most dangerous weapon.Fognini, with his bandana, shock of black hair and beard, looks from a distance like a taller and much slimmer Diego Maradona.He picked up an official rebuke for racket abuse after Anderson drew level at the end of the second set.
