Del Potro saddened by Almagro 'agony'

Del Potro, who showed compassion and class consoling the anguished Almagro, took treatment earlier in the match for an apparent groin injury leaving his fitness in question for the third round.

And, though shoulder and back injuries hampered his warm-up in Lyon, Del Potro appeared back to his best on Court 6 at Roland Garros.

The victory set up a clash with former US Open champion Del Potro, who is still working his way back up the rankings after wrist injuries that nearly ended his career.

Murray toiled against the talented, inconsistent Martin Klizan, prevailing 6-7 (3-7) 6-2 6-2 7-6 (7-3) - rallying from a 5-2 deficit in the fourth set.

He was however hopeful of being fit for his much anticipated third-round duel with world No. 1 Andy Murray.

But, assuming he is close to fully fit, Del Potro will present a serious test of Murray's Roland Garros ambitions with the pair having played in two classic matches a year ago - the Rio Olympic final and a marathon Davis Cup five-setter - both stand-out memories.

Having lost virtually three years of his career to wrist problems, Del Potro took little pleasure in advancing to a clash with world number one Andy Murray.

Tuesday's match was Del Potro's first on the Paris clay since 2012, when he lost in the quarter-finals to Roger Federer.

It was a similar story in the third set with both players pummeling each other until Wawrinka broke Dolgopolov a second time to clinch victory and deny the world number 89 his first third round spot in Paris since 2011.

Del Potro didn't have to finish the match, as Almagro was forced to retire due to a knee injury, saving the Argentinian extra tennis considering the match was going at least four sets.

Third seed Stan Wawrinka was tested by Alexandr Dolgopolov but came through 6-4 7-6 (7/5) 7-5 to set up an enticing battle against Fabio Fognini. I can imagine what you're feeling.

"I say to him, 'Try to be calm.' Think about his family, his baby, "' said 29th seed del Potro, who has known Almagro since their junior days.

"I just do what my heart feels, you know?" "Juan Martin is playing a lot better than his ranking", said Murray.

The Yorkshireman is into the last 32 for the first time at Roland Garros where he will play South Africa's Kevin Anderson.

It is the first time the 22-year-old has progressed to the third round of the French Open after being knocked out in round two in 2015 and 2016.

"Today was a very good match, especially winning 12 games in a row", Nishikori said.
