NEW YORK—On Aryna Sabalenka’s first chance to end her U.S. Open semifinal against Jessica Pegula for the chance to play for a second consecutive trophy, the defending champion dumped what should have been an easy overhead into the net, then stared at the ground.
On Sabalenka’s second chance, she missed a clumsy volley—and maybe shouldn’t have even ventured forward, because she went just 15 for 27 when up at the net. Uh, oh.
