The first set was reasonably competitive but the second set was all Serena and she completely bossed the game.
Serena put on a real display and this should hopefully have silenced her critics for at least another day.
The second semi-final Angelique Kerber Varvara Lepchenko in three sets. I was expecting Angelique to have a rather more routine win.
It shows Vavara has really developed her game because this time last year she was getting knocked out in round one.
Angelique has had a good year too has made it to finals of key tournaments and has now established herself as top ten player.
