It is funny that Serena acts like every match, even a match with Justine on clay is hers to win or lose. Mary Joe Fernandez says that Serena at her supposed best is too good, and Justine knows that before a match with Serena on clay. If that is true how do you explain the 4-1 head to head. Justine went 1-1 vs Serena on clay when she barely a top 10 player, and Serena at her most dominant peak. She then went 2-0 vs Serena on clay when she was coming into her own, and Serena was still at her dominant peak. Now the recent win with Serena past her dominant peak to a degree. So it is pretty clear she owns Serena on clay. Does Serena mysteriously not play her best vs Justine on clay almost every time they play? No of course not. Justine's best IS better then Serena's best on clay. Serena's errors are caused by Justine's superior skill and ability on clay. Some of the very best and most consistent clay courters have made 60+ unforced errors in a very high quality match. Serena is not as consistent or strong as some of those women on clay, yet if she makes over 20 unforced errors, no matter who she is playing, she is supposably way off her game. Please, what a joke.
