Nadal drops a set to Schwartzman before rain delays quarters

Timeline of Day 7 How Rafa Serena and Maria enjoyed a super Saturday at Roland Garros

Fears of yet another injury appeared early on in the encounter as the Spanish icon requested taping for both of his wrists, and the rain delay may end up helping him.

The quarter-final match between Marin Cilic and Juan Martin del Potro will also resume tomorrow, with the two top-five players locked at 5-5 in the first set tie-break.

Nadal had won 37 consecutive sets at Roland Garros since his 2015 quarter-final defeat by Novak Djokovic but dropped serve three times to the enterprising Schwartzman in an exciting opener.

For Nadal, that happened when he was down a break at 3-2 in the second set, and the delay of a little less than an hour seemed to help him begin to change course against Schwartzman, a 1.7 metre Argentine who was putting almost every shot right where he wanted to in the early stages.

Nadal then fought back to lead the second set 5-3, before heavy rain brought a halt to the last-eight encounter on Court Philippe Chatrier.

Prior to the delay Nadal was not playing his best tennis, and was struggling to find his usual clay court rhythm.

Having gone two sets up on the back of big hitting from the baseline, sixth seed Anderson threw Schwartzman a lifeline in the contest while serving for the match at 5-4.

Schwartzman came out the traps flying.

But as in the first set, Nadal's riposte was swift, chasing down a drop-shot to set up a break-back opportunity, converted when Marterer thumped a forehand long.

But Schwartzman delivered a warning to Nadal in the first game - forcing him to save four break points, before finding a way through on the Spaniard's following service game.

Nadal pumped his fist and yelled: "Vamos!".
