Aryna Sabalenka vs Ekaterina Alexandrova — R16 — Canadian Open

The break-point ledger favored the player who lost. Sabalenka took 6 of her 11 chances to Alexandrova's 6 of 15, but the top seed — an 81 percent favorite with the betting market — never matched the No. 16 seed's first ball, 67 percent of first-serve points won against 61, with both women holding exactly 10 of 16 service games. Alexandrova broke in game 10 for 6-4 to close it two hours, 29 minutes in, after the No. 1 had saved two match points along the way. It is her second win on record over Sabalenka while the latter sat at No. 1, and it trims a series Sabalenka led 3-1 coming in. A quarterfinal with Elina Svitolina (No. 10) is next.
