Wawrinka, Thiem And Raonic Progress
Rafael Nadal eased into the last-16 of the Italian open when his second-round opponent Nicolas Almagro retired after sustaining a knee injury early in the first set.
Nadal, who is the clear tournament favourite and looks to be in the form of his life on clay this season, raced into a 3-0 lead before Spanish compatriot Almagro felt his left knee with less than half an hour played.
Nadal is seeded fourth in Rome, where he is bidding for a record eighth title.
Japan's Kei Nishikori, the number seven seed, beat Spaniard David Ferrer 7-5 6-2 earlier in the day and will play either Britain's Kyle Edmund or argentine Juan Martin Del Potro in the last 16.
Earlier, Stan Wawrinka beat a plucky Benoit Paire in the italy open second round as Dominic Thiem beat Pablo Cuevas and Milos Raonic beat Tommy Haas.
Number three seed Wawrinka took the match 6-3 1-6 6-3. The Swiss player now faces American John Isner in the third round.
Number eight seed Austrian Thiem defeated Uruguayan Cuevas 7-6 6-4. Thiem now faces American Sam Querrey in the third round.
Number five seed Canadian Raonic beat German Haas 6-4 6-3 to face Tomas Berdych in the next round.
