Sascha Zverev’s quarterfinal at the Canadian Open showed how much he’s grown. After losing two set points and dropping the first set to Popyrin, the old Zverev might’ve smashed a racket. This time, he just launched a ball into the stands—then regrouped and took the match. With this win, Zverev joins Novak in the 75 semifinals club. Up next: another clash with Khachanov. Has Zverev finally mastered his emotions on court? #Sports #Tennis #Zverev
