Her serve was better in 2018 though. Now it's just slightly above average imo.It seemed to me that Svitolina had more pace on many of her shots than usual. If this is something she's been working on improving - this could be a positive development for her. She very well can be physically capable of injecting more pace into her shots - but perhaps it's the mental aspect of her game that holds her back when she becomes too passive. Afterall she was able to improve her first serve a lot after putting much work into it.
