Rafael Nadal and Roger Federer both registered straightforward victories to move into the third round of the Shanghai Masters.
World number one Nadal needed just 54 minutes to beat America's Jared Donaldson 6-2 6-1.
Federer, chasing his 94th ATP title, found his rhythm as the match progressed to beat Argentine Diego Schwartzman 7-6 (7-4) 6-4.
I regret to back Diego Schwartzman to win 1st set against Roger Federer, he so stupid when he lead 2-0 on tiebreak on got punished with his errors. I think we don't see any upset untul this tournament end.
