Regardless of injury this is a poor loss. Everyone in qualies is ranked extremely low, many ranked in the 200's and two players ranked less than 175. Her opponent today is ranked "279th". Not a good return, especially given the low quality of the competition.
Never calculate in tennis. If you cant lose to someone lower ranked than in the subconscious you shouldnt beat someone better ranked. Tennis is a process, you give your self the best chance to play well by doing things you do well.. It is not about wta bumbers or score board number, it is about the next shot..
You judge her performance on statistics, you would hate it if someone did that to you, because than anyone richer or taller than you would be considered better..
