Serena Williams produced a masterclass in sportsmanship in the third round of the Australian Open on Saturday.Having showed why she was the tournament favourite with a straight sets victory, she was then seen consoling her young opponent at the net. The match went unsurprisingly all Williams' way, dropping just three games to Dayana Yastremska as she powered her way through to the fourth round.Yastremska's victories in the first and second round are the first wins of her career at a Grand Slam while Serena Williams is aiming for her 24th Grand Slam title.Williams' 6-2 6-1 victory was particularly dominant and the Ukrainian player visibly struggled to keep up with the pace of her more experienced opponent's play.  As they approached the net following the straight sets match, Yastremska was unable to hold back her emotions after such a heavy loss.   But Williams was typically graceful in victory though and spent some time consoling her opponent.She was heard telling the 18-year old "You are amazing, you are so young, don't cry."

Ukrainian Yastremska was born one year after Serena Williams won her first ever Grand Slam and in a later interview recalled watching the American on TV as an 8-year old.

Yastremska isn't the first person to struggle to keep up with Williams this week. 

The American has won all six sets she's played so far in the tournament and is currently on a run of 20 straight victories in the Australian Open since 2017.

Her victory in the third round was typical of the style she's displayed so far in the tournament, forcing numerous errors and breaking the Ukrainian's serve at the first two opportunities.

Her opponent for the fourth round will be more of a test for the American as she will either face her sister Venus or World number one Simona Halep who play each other later on.
