Sascha Zverev showed true ice-cold nerves in the Canadian Open quarters, rallying from a set down against defending champ Popyrin. Even with his girlfriend Sophia Thomalla cheering from afar, Zverev kept his cool after a rowdy heckler disrupted play, flipping the script with a dominant serve and tactical returns. This marks his first Masters 1000 semifinal since Paris—can he keep the momentum against Khachanov? #Sports #Tennis #Zverev
