She lead 3-0 cause Li wasn't in the match, playing like crap.The begining of the match was ugly and Venus had not much to do.Li is playing better now and Venus choked a bit.
Not related to Serena's loss imo
She probably did. Its like the Australian Open, French Open, would have probably been wimbledon but serena lost in the final which ment venus won so she couldnt loose then. But i put venus finding out about serena's loss 1 of the reasons venus lost today.
