You'll see better serves at your local club. Apparently she had a serious shoulder injury so maybe that's why it's so tame. Very odd.
Interesting match between 18-year old lucky loser Daria Kasatkina and Daria Gavrilova finished recently. Kasatkina was replacing Maria Sharapova's place in the draw, and it was her very first Grand Slam match, so it was a huge opportunity for both players. Gavrilova completely lost her focus and temper during the third set, while Kasatkina displayed professionalism far beyond her years to stay strong and close out. I was impressed by her demeanour and confidence.
Monfils meanwhile is entertaining everyone with his antics against Marchenko.
