Melbourne, Australia (SportsNetwork.com) - World No. 1 Rafael Nadal, three- time runner-up Andy Murray and four-time champion Roger Federer were among Thursdays winners, while fifth seed Juan Martin del Potro was a stunning second-round loser on another brutally hot day at the Australian Open. On a day when the temperature soared to a sweltering 110 degrees and the show courts were covered by their retractable roofs, the 2009 champion Nadal put on a clinic in beating 17-year-old Aussie Thanasi Kokkinakis 6-2, 6-4, 6-2 at Rod Laver Arena. "Very happy to see the roof out there today," Nadal said. The reigning U.S. and French Open champion, who was a runner-up at Melbourne Park two years ago, will meet oft-injured, flashy former top-10 Frenchman Gael Monfils on Saturday. Nadal beat Monfils in a final at an Aussie Open tune-up in Doha just two weeks ago. The stifling weather on Day 4 resulted in the tournaments Extreme Heat Policy being put into effect, suspending action on the outside courts for a few hours. And there was also some rain, lightning and thunder on a wild- weather Thursday. The biggest shock of the first four days occurred early Friday morning in Melbourne when capable Spaniard Roberto Bautista Agut toppled the former U.S. Open champion del Potro 4-6, 6-3, 5-7, 6-4, 7-5, with play wrapping up at 1:20 a.m. local time. Bautista Agut set himself up with a match point via ace, moving the score to 40-15 in the 12th game of the final set, and sent del Potro packing when the big Argentine netted one final forehand return after 3 hours, 50 minutes. The 6-foot-6 "Delpo" has never advanced beyond the quarterfinals in Melbourne and exited in the third round here last year. Meanwhile, a fourth-seeded Murray got past game Frenchman Vincent Millot 6-2, 6-2, 7-5 at Laver, where the roof was re-opened after the weather improved. Murray won the last 23 points of the match to come back from 1-5 down in the third set. "It was 6-5 when I went to serve for it, and someone shouted out, You won 19 in a row," Murray said. "I would say thats probably the most Id ever won in my career by far. I dont really know how I did it." The two-time major titlist and reigning Wimbledon champion lost to Novak Djokovic in last years marquee Aussie finale. Murrays third-round opponent will be Spanish left-hander Feliciano Lopez. The sixth-seeded former No. 1 Federer played under the roof at Hisense Arena and dismissed Slovenias Blaz Kavcic 6-2, 6-1, 7-6 (7-4) for his 70th career win at the Aussie Open (70-8). The 17-time Grand Slam king is seeking his first Aussie title since 2010. Federer said he didnt mind the switch to Hisense after hed played 63 consecutive matches at Laver Arena since 2004. "It was nice ... its not really different to Rod Laver Arena really," Federer said. "Dimensions feel the same, the crowds were really nice, great atmosphere. I was happy playing there." The 32-year-old Federer will return to the court against Russian Teymuraz Gabashvili on Saturday. Tenth-seeded Frenchman Jo-Wilfried Tsonga, the 2008 runner-up to Djokovic, topped Brazilian qualifier Thomaz Bellucci 7-6 (8-6), 6-4, 6-4, while 11th- seeded Canadian slugger Milos Raonic downed Romanian veteran Victor Hanescu 7-6 (11-9), 6-4, 6-4. Tsonga will take on fellow Frenchman Gilles Simon, while Raonic will tangle with rising Bulgarian star Grigor Dimitrov in the round of 32. Sixteenth-seeded Japanese Kei Nishikori reached the third round by besting Serb Dusan Lajovic 6-1, 6-1, 7-6 (7-3) prior to the suspension of play. Nishikoris next opponent will be American Donald Young, who upset 24th-seeded Italian Andreas Seppi 6-4, 2-6, 6-3, 4-6, 7-5.
