Now players will have to beat both sisters when they enter the same tourney
The announcers made a good point during the finals. With Venus and Serena ranked 1 and 2, if they enter the same tournament other players would have to beat both of them to win the title-- this of course assumes the seeding holds up and neither sister gets upset earlier in the tournament.
That must suck for the other top players because they usually play one sister better than they do the other.
For example, Linday seems to play closer matches with Serena than Venus. Martina plays Venus close but gets blown away by Serena. Jennifer plays Serena close but always loses to Venus...etc.
I imagine it would be frustrating to beat Venus then still have to beat Serena to win the title. That's a tall order.
