Was Hingis Nervous?

I am sadden by her Loss. I know the talks have happened, but not on the board much lately. Anyway, i was rooting for her to pull this trick out of the bag, but Razzano was on fire. Hingis picked it up in the end, but too little to late.

Was she Nervous? something didn't click.

she spent too much energy on her match vs shuai. And then she had to play again the next day.
