ROME (AP) — Sa kabila ng pananakit ng likod, napabilang pa rin si Roger Federer sa tennis heavyweight na sasabak sa third round ng Italian Open.

Ginapi ng 16-time major champion si Alexander Zverev, 6-3, 7-5, nitong Miyerkules (Huwebes sa Manila) sa larong siya man ay nasorpresa sa kinahinatnan.

"I was expecting to lose in straight sets today. That was the mindset going in, so to win in straights is actually a really big surprise to me," sambit ni Federer, sumabak sa torneo bilang last-minute entry.

Goodbye PBA? John Amores, tinanggalan na ng professional license!

"I played cautious, and I only decided after the warmup that I was actually going to play."

Nagwagi rin sina top-ranked Novak Djokovic, Andy Murray at seven-time Rome champion Rafael Nadal sa red clay court ng Foro Italico.

Sa women's division, maaga namang nasibak sina Australian Open champion Angelique Kerber, fourth-seeded Victoria Azarenka , at Madrid Open winner Simona Halep.
