Well, she should be confident. She is obviously an amazing player. Those big groundies can take her deep into the draw. Not easy for her to play Serena though.... even IF she manages to out slug Serena, which she is capable of.... Serena is very quick around the court and with more aggression.
Can't wait to see how she goes. But for the moment, her first round, Emma Laine, is not a pushover IMO. Will be a good warm up for her against Laine.
