For starters Dellacqua was a huge reason Szili won the doubles. Adriana still would have had to play reasonable, but teaming with someone so consistent that gets back 90%+ of their returns and is great at the net helps enormously! I saw Dellacqua play doubles with Sewell and they won 1st match main draw at Aust Open and Sewell was playing crap other than a few good volleys and dropping serve to love! It was clearly Dellacqua that got them through that match, she was playing superbly as she did against Maja in singles.
Szili hits average pace, not that hard, kind of the defensive pace of Evie. In fact I think their games are quite similar except that Evie has a bigger serve and much better court movement! Szili needs to be more aggressive in my opinion, she is in a slump as she has become to defensive in her play, well thats what I suspect. Her game is based on consistency with controlled aggression. I dont think she's been working hard enough since the Aust Open, perhaps her confidence was too high and she expected to romp in the results without maintaining all the hours of training because she thought she was better than most of the players here!
