Snapshots from Australia

Eighteen-year-old Madison Keys -- at No. 36 the youngest player in the WTA top 50 -- turned heads when she upset seventh-seed Simona Halep in the first round at last week’s Apia International in Sydney, a warm-up to the Australian Open. After making it all the way to her first WTA premier-level semifinal in Sydney, Keys moved on to Melbourne, where she beat Patricia Mayr-Achleitner in the first round of the Australian Open before falling Wednesday in the second round. With doubles play still to go, Keys checks in with photos from Down Under.

What a great week in Sydney and a pretty good start of the year for me! Sydney is a very special place -- it’s a beautiful city, and the fans are amazing. I always try to enjoy the places I travel to while playing in WTA tournaments. As you can see, Sydney was the perfect place for evening strolls along the water and I got a beautiful shot of the Opera House. I can’t wait to come back and play here next year in preparation for Melbourne.

Aga Radwanska and I before Kids Day in Melbourne. Being part of this event is always such a great way to give back to the sport and meet some of the youngsters. There were Nickelodeon characters and entertainers along with us on court, which made it double the fun! I hope the kids had lots of fun and found some inspiration from us.

Think warm thoughts … think warm thoughts … think warm thoughts. The cold pool is so good, yet so cold, at about 50 degrees Fahrenheit! It might not be so fun when you're in one, but you feel so great after, and it’s definitely one of the best ways to recover. I needed this, especially after my very long, three-set match on Sunday. It was the perfect remedy for my body after winning 6-2, 6-7, 9-7 against Austria’s Patricia Mayr-Achleitner.

I’m so happy to be inside here. It's 109 degrees Fahrenheit in Melbourne! I’m enjoying my air conditioner here while getting ready for the next round, against China’s Zheng Jie. Can you see the Yarra River behind me? It’s one of the many unique sights of Melbourne.

In the locker room waiting to go on the court for our first-round match, So my doubles partner, Alison Riske, and I decided to take a selfie. Wish us luck!
