Rafael Nadal goes under the lights against America's Tim Smyczek
Nadal looked very sharp in his opening round 6-3, 6-2, 6-2 win over Mikhail Youznhy. Next up is No. 112 Smyczek. The 27-year-old from Milwaukee gets the big stage of Rod Laver Arena for his first-ever match against the Spaniard. Can he give Cheeseheads something to cheer about this week?
Roger Federer and Maria Sharapova move to the day session on Rod Laver
Two days after anchoring the night session, Federer and Sharapova get the day treatment. Sharapova plays No. 150 Alexandre Panova of Russia (second match, Rod Laver Arena) and Federer follows against Italy's Simone Bolelli. Hard to see anything but straight set wins in those.
Australia's Special Ks look to work their evening magic again
Thanasi Kokkinakis' five-set win over Ernests Gulbis out on Show Court 3 was the most exciting and exuberant match of the first round. Now the 18-year-old faces his big-serving countryman Sam Groth on Hisense Arena (6 p.m. local time, 2 a.m. ET), a famously anodyne and sleepy venue. With the promotion of Margaret Court Arena as the new No. 2 court at Melbourne Park, Hisense Arena is now a general admission court, so we're curious to see what happens when you fill it up with Aussie fans cheering on two Aussie guys.
Nick Kyrgios fought through his back injury to beat Federico Delbonis in five sets on Monday and the biggest concern is whether his body will recover for his round two match against No. 23 Ivo Karlovic (5 p.m. local time, 1 a.m. ET, Show Court 3). The good news for Nick: there won't be many rallies in this one.
But top billing for the Aussie youth went to Bernard Tomic. He plays No. 22 Philipp Kohlschreiber in the last match on Margaret Court Arena.
The Bryans and The Williams sisters begin their doubles tournaments
Venus and Serena are back in the doubles draw and will open against No. 11 seeds Anabel Medina Garrigues and Yaroslava Shvedova (third match, Show Court 2). The top-seeded Bryans play the Australian duo of John Millman and Benjamin Mitchell (second match, Court 7).
More matches to watch
Simona Halep  vs. Jarmila Gajdosova (second night match, Rod Laver Arena): Halep wasn't her best in her first round win over Karin Knapp, and the crowd will be firmly behind Gajdosova, who won her first Australian Open main draw match on Monday after 10 years of trying. Gajdosova is a big hitter off the ground and Halep could be in trouble if the Aussie finds her range.
Andy Murray  vs. Marinko Matosevic (second match, Margaret Court Arena): No doubt Matosevic will give us something Vine-able in this match.
David Goffin  vs. Marcos Baghdatis (second match, Court 6): Baghdatis needed five sets to get through his first round match, so there are questions surrounding his recovery. But this should be a fun baseline match.
Karolina Pliskova  vs. Oceane Dodin (second match, Hisense Arena): If you want to see what all the hoopla is about Pliskova, tune in. A semifinal run here would not surprise me.
