This was just her second major since she fell in the opening round two years ago, after a brief return to Wimbledon last season.
It was in Miami, in just her second tournament back this season, where the 28-year-old was able to transfer practice to the match court with a semi-final run.
“I think the personal level and personal expectations for me are always high. And coming in here I was trying to be a little bit more realistic and take it one day at a time,” Azarenka said.
“I had some good practice days finally after Rome, but, you know, it didn't come out on the court today. Even though I'm doing good things in practice, I am not able to transfer it to the match.”
Azarenka left no doubt of her hunger to return to the winning fray and she displayed her fair share of brilliance from the baseline against Siniakova, but having broken three times in the second set, each time she was unable to consolidate. “I think that today I just didn't use the opportunities that I created with my serve, and the first shot was not as aggressive and giving me that kind of feeling going forward,” she said.
