Well, it wasn't the summers day most spectators were expecting when they turned up to Melbourne Park for a day at the tennis. 

The rain was coming down, not heavily, but still raining as the first game at Rod Laver Arena, however, games on outside courts were delayed. 

The rain eventually let up though and everything was back to normal. 

One of the biggest upsets of the Grand Slam did come from American teenager Amanda Anisimova as she overcame world no. 11 Aryna Sabalenka.
