World number two Rafael Nadal raced into the third round of the ATP Indian Wells Masters as Roger Federer made a less speedy but still successful start to his quest for a sixth title on Sunday.
Nadal, a three-time Indian Wells winner, needed just 72 minutes to get past overmatched Jared Donaldson, 6-1, 6-1.
Federer, who is seeking to break out of a tie with top seed Novak Djokovic for most titles in the California desert, looked set for a similarly easy time of it, but had to turn back a second-set challenge from German Peter Gojowczyk in a 6-1, 7-5 win.
Fourth-seeded Federer said he was relieved not to go to a second-set tiebreaker after falling behind 3-1 to the free-swinging German, who is ranked 85th in the world.
The Swiss regained the break and, after saving four break points to make it 4-4, cruised home.
Federer next faces compatriot Stan Wawrinka, a three-time Grand Slam champion currently unseeded as he continues his return from injury.
Wawrinka won a taut thriller against 29th-seeded Hungarian Marton Fucsovics, 6-4, 6-7 (5/7), 7-5, finally sealing it on his fifth match point after three hours and 24 minutes when Fucsovics lofted a lob long.
