Game context
Ostapenko enters as the clear favorite against the veteran Zhang in this National Bank Open second-round matchup, reflecting her superior ranking, aggressive baseline power, and historical dominance in their head-to-head. The Latvian, who received a first-round bye after a Wimbledon mixed-doubles title, has not played singles in a month but holds a 2-0 record against Zhang with straight-set wins, including on hard courts. Zhang, 37 and ranked around No. 62 after a strong comeback season, arrives with momentum from snapping a seven-match skid versus Putintseva via a confident 6-4, 6-1 victory, though her counterpunching style has historically struggled against Ostapenko's first-strike offense and error-prone but high-variance game. No major injuries or withdrawals affect the draw.
