Top-ranked Rafael Nadal won his first match at the $4.5 million Sony Ericsson Open, Roger Federer reached another milestone during his second-round victory Saturday, but defending champion Andy Roddick was ousted from the tournament.
Nadal, playing under the lights, topped Japan's Kei Nishikori, 6-4, 6-4 in a second-round match.
At Indian Wells, Nadal played for the first time since the Australian Open (he missed some time with a left thigh injury) and made it to the final, losing to Novak Djokovic in three sets. Next up for Nadal will be fellow Spaniard Feliciano Lopez, who upended 26th seed Juan Ignacio Chela, 7-6 (7-3), 3-6, 6-4.
Federer cruised to a 6-3, 6-3 win over Radek Stepanek in just 62 minutes. Federer, the back-to-back Miami champion in 2005 and '06, is seeded third this year after Nadal and red-hot Djokovic.
Saturday marked Federer's 762nd career win, tying Pete Sampras for seventh on the all-time list. He also moved to 11-2 lifetime against Stepanek and will next face 32nd-seed Juan Monaco of Argentina. Monaco topped Ukraine's Sergiy Stakhovsky, 6-4, 6-7 (2-7), 6-4 on Saturday.
Roddick, who beat Tomas Berdych last year, was toppled by Uruguay's Pablo Cuevas in straight sets 6-4, 7-6 (7-4). Roddick has been suffering from a case of chest congestion and he was clearly ailing on Saturday.
Seeded eighth, Roddick double-faulted six times in the match, which lasted just under two hours at Crandon Park, and was unable to fend off 15 aces by the 67th-ranked Cuevas.
The other night match saw Berdych, the seventh seed, beat Ruben Ramirez Hidalgo, 6-1, 6-7 (4-7), 6-0.
Austria's Jurgen Melzer, seeded 10th, lost to good friend and doubles partner Philipp Petzschner of Germany, 6-3, 6-4.
Nicolas Almagro, the 11th seed from Spain, downed Portugal's Frederico Gil, 6-4, 3-6, 6-2. Also Saturday, 13th-seeded Mikhail Youzhny defeated Yen-Hsun Lu, 6-1, 6-0; 15th-seeded Jo-Wilfried Tsonga downed Teymuraz Gabashvili, 6-3, 6-7 (3-7), 6-3 and 18th seed Marin Cilic lost to Janko Tipsarevic, 6-3, 7-6 (7-4).
Other seeded second-round winners Saturday included No. 21 Alexandr Dolgopolov and No. 25 Gilles Simon. Florian Mayer ousted 20th seed Albert Montanes, Olivier Rochus beat No. 22 seed Marcos Baghdatis, and Carlos Berlocq got by No. 28 seed Ernests Gulbis.
The 2011 Miami champion will collect $611,000.
