Former Williams sisters` coach, Rick Macci, has highly praised Aryna Sabalenka`s performance after she won the Miami tournament on Saturday.
Macci tweeted: `What I like most about Sabalenka and her game is her great Courage. There is a fine line between Courage and Stupidity. But she tries to dictate and control the game in every match. BAM! No fear.`
The specialist also noted that from a biomechanical point of view, the Belarusian`s serve is one of the best in women`s tennis.
