The action Down Under on Monday did not disappoint. A few big stars continued their winning streaks while some underdogs came out victorious on Day 2. Novak Djokovic became a fan on his day off as he was spotted courtside cheering on his friend Filip Krajinovic.

These are the Top 5 Photos from Tuesday:


Jessica Pegula Comes Back

Down 2-5 in the opening set against two-time major champion Victoria Azarenka, Pegula would save a set point en route to claiming five consecutive games to take the set 7-5. Azarenka struggled with her breathing towards the end of the first-round bout and needed a medical timeout. 

In the end, Pegula captured her biggest win over the Belarusian, 7-5, 6-4. She will take on Samantha Stosur next.

The Russian is still flying high after helping Team Russia grab the ATP Cup title just days ago. Rublev easily defeated Yannick Hanfmann, 6-3, 6-3, 6-4, to advance to the second round. The world No. 8 is riding a five-match winning streak.

Novak Djokovic Sits in the Stands

Here's a sight you usually don't see: A world No. 1 was spotted in the stands cheering on a friend. Djokovic came out to support countryman Filip Krajinovic in his opening round win over Robin Haase. With the event allowing only half capacity, it leaves a lot of room for players to sit and watch matches comfortably.

Elina Svitolina Wins in Straights 

The world No. 5 was put to the test in a tough 6-3, 7-6(5) opening win against Marie Bouzkova. The last time these two squared off was in Monterrey's final round last year, with the Ukrainian prevailing in three sets. Svitolina will face American Coco Gauff, who comfortably eased past Jil Teichmann.
