Serena Williams has yet to lose a set in Australian Open

The GIST: Messing up our circadian rhythms to watch tennis all night has been totally worth it, thanks to some stellar action in the Australian Open.

Staying put: First, the really important news: through two rounds, Serena Williams hasn’t lost a set. Classic. And No. 1 Ashleigh Barty, who’s playing in front of a home crowd, and most recent Grand Slam winner, No. 3 Naomi Osaka, are all still making a run for the title.

• No major shockers on the men’s side (outside of wild card entry Thanasi Kokkinakis [pronounced TA-NA-SI KO-KI-NAK-IS] playing in a $6 Kmart shirt), with most of the top guys (we miss you Roger) still in the hunt.

Going home: We’ve seen three surprising exits from this tournament already. We were pretty sad to see No. 8 Bianca Andreescu lose her second-round match on Tuesday — after her return to the court following a 15-month injury absence — and Venus Williams struggle through an ankle injury in her second-round match.

• And last night, reigning champ and No. 4 seed Sofia Kenin lost in straight sets to Kaia Kanepi. Sports.

Up next: Serena, Osaka, and French Open winner Iga Swiatek are all on the Friday schedule (but tonight, our time) on the women’s side, and over on the men’s, our very own Taylor Fritz is facing No. 1 Novak Djokovic (pronounced JOKE-OH-VITCH). Check out the schedule and follow the scores.
