What are you talking about maybe Ana had pressure to perform, but Halep had no pressure whatsoever she was in the semis regardless. Halep could have done the smart thing and put in a decent effort after losing the first set having secured enough games to win the group but still lose the second set and give Ana the victory to eliminate Serena. Talk about Simona, giveth and taketh away from Serena. I mean Simona laid a smack down that nearly eliminated Serena from contention, but she also won the crucial set that gave Serena the reprieve. I doubt Halep would have been crucified by anyone other than a few crazy Serena fans for tanking that match. I would have been disappointed in her if she didn't put in some effort as there are paying customers in attendance, but I wouldn't have faulted her for doing the smart thing.
