Melbourne, Australia (SportsNetwork.com) - Three members of the "Big Four" won second-round matches Wednesday at the 2015 Australian Open.
Second-seeded former world No. 1 Roger Federer had to come from behind to beat Italian Simone Bolelli 3-6, 6-3, 6-2, 6-2, while third-seeded former top- ranked star Rafael Nadal needed all five sets and survived cramps to hold off American Tim Smyczek 6-2, 3-6, 6-7 (2-7), 6-3, 7-5 at Melbourne Park.
The 2014 Wimbledon runner-up and 17-time Grand Slam king Federer owns four Aussie Open titles and was the 2009 runner-up here to Nadal.
Federer's next opponent will be Italian Andreas Seppi.
Playing just his 10th tour-level match since July of last year, Nadal ground out a comeback victory against the world No. 112 Smyczek.
"I don't know what was going on," Nadal said in a courtside interview. "I started to have cramps in different places. I was not in the perfect shape."
The 14-time Grand Slam champ and reigning French Open titlist maintained his record of never losing to a qualifier at a Grand Slam championship, but his win kept fans at Rod Laver Arena on the edges of their seats.
With Nadal serving at 6-5 in the fifth set, Smyczek gave the Spaniard a break.
A fan shouted just as Nadal was about to strike his first serve, causing him to miss long. As Nadal glared into the stands, Smyczek motioned that he should retake the serve. Nadal did -- and won the point and the match.
Smyczek won Nadal's respect.
"What he did at the end of the fifth is just amazing," Nadal said. "Very few players can do that after four hours something of a match, at 6-5, love-30. So I just will say thanks to him because he's a great example what he did today."
The former Oz champ and two-time runner-up triumphed in 4 hours, 12 minutes to set up a third-round meeting with Israeli Dudi Sela.
Nadal lost to Stan Wawrinka in last year's finale in Melbourne.
Meanwhile, sixth-seeded three-time Aussie Open runner-up Andy Murray eased past Aussie Marinko Matosevic 6-1, 6-3, 6-2 on Day 3 at the fortnight. The two-time Grand Slam champion's third-round opponent will be Portuguese Joao Sousa.
Seventh-seeded Tomas Berdych handled Austrian Jurgen Melzer 7-6 (7-0), 6-2, 6-2, while 10th-seeded Grigor Dimitrov got past Slovak Lukas Lacko 6-3, 6-7 (10-12), 6-3, 6-3 and 14th-seeded South African Kevin Anderson beat Lithuanian Ricardas Berankis 6-2, 6-2, 7-6 (7-3).
In other action involving seeds, former Aussie runner-up Marcos Baghdatis upset No. 20 David Goffin 6-1, 6-4, 4-6, 6-0; Aussie Bernard Tomic took out No. 22 Philipp Kohlschreiber 6-7 (5-7), 6-4, 7-6 (8-6), 7-6 (7-5); rising Aussie Nick Kyrgios drove out No. 23 Ivo Karlovic 7-6 (7-4), 6-4, 5-7, 6-4; No. 24 Richard Gasquet grounded Aussie James Duckworth 6-2, 6-3, 7-5; last week's Sydney champion Viktor Troicki of Serbia dismissed No. 26 Leonardo Mayer 6-4, 4-6, 6-4, 6-0; the aforementioned Sela surprised No. 28 Lukas Rosol 7-6 (7-2), 5-7, 7-5, 6-3; Seppi erased No. 29 Jeremy Chardy 7-5, 3-6, 6-2, 6-1; and Sousa bested No. 32 Martin Klizan 4-6, 7-6 (7-4), 6-4, 1-0, retired.
Also advancing were Aussie Sam Groth and Tunisia's Malek Jaziri.
The second round is scheduled to conclude Thursday, including matches for top- seeded four-time Aussie champion Novak Djokovic and the fourth-seeded reigning titlist Wawrinka. The seven-time major winner Djokovic will take on Russian Andrey Kuznetsov, while Wawrinka will look to extend his Melbourne winning streak to nine matches with a meeting against Romanian Marius Copil.
Also on the Day 4 schedule will be fifth-seeded U.S. Open runner-up Kei Nishikori, eighth-seeded Canadian slugger Milos Raonic, ninth-seeded David Ferrer, and former No. 1 and former Aussie runner-up Lleyton Hewitt.
