Rome - Coming off a win over Rafael Nadal in Madrid last week, Fernando Verdasco eased into the second round of the Italian Open on Monday when Alexandr Dolgopolov retired with a stomach ache.
After the 16th-ranked Verdasco won the first set 6-0, Dolgopolov called for the trainer then clutched his stomach as he went over to shake Verdasco's hand and concede.
Also on a clear but windy day at the Foro Italico, 13th-seeded Gael Monfils beat Alex Bogomolov Jr of Russia 6-4, 6-1.
In women's action, Anabel Medina Garrigues of Spain defeated Zheng Jie of China 6-2, 6-1; and Chanelle Scheepers of South Africa eliminated Jarmila Gajdosova of Australia, 6-4, 7-6 (7/3).
This tournament is the last major clay court warm-up for the French Open, which starts in two weeks.
