Despite a rocky start that saw her grappling with inconsistent serves and double-faults, she found control in the second set. Sabalenka entered the hard-court Major with limited match play. She failed to defend her Cincinnati Open title earlier this month, and it was the only warm-up tournament she played since Wimbledon. The Belarusian skipped both the Washington and Toronto events.Watching attentively from her box at the US Open was newly added mentor and Belarusian doubles legend Max Mirnyi. He won 10 Grand Slam doubles titles and has joined long-time coach Anton Dubrov’s crew to sharpen Sabalenka's gameplay.Sabalenka was full of praise for the legend after the match (via BBC): "I feel like we improved a couple things together and I’m looking forward to working more with this wonderful guy... Hopefully we can finally improve my volley – maybe one day you will see me coming to the net more often but for now it’s a work in progress."In a playful reference to Mirnyi's nickname, 'Beast,' she added:"Now you can call our team Beauty and the Beast."With Mirnyi in her corner, Sabalenka is aiming to break Flushing Meadows history by becoming the first woman since Serena Williams to defend her US Open title. Up next for the World No. 1 is a clash against 22-year-old Polina Kudermetova.
