Hsieh Su-wei and Jelena Ostapenko enter this National Bank Open doubles matchup as a proven pairing that captured the 2026 Brisbane title with straight-sets dominance and reached the Australian Open quarterfinals earlier in the year. The experienced duo combines Hsieh’s tactical precision and net play with Ostapenko’s aggressive baseline power on the hard courts in Toronto. Their opponents, Ulrikke Eikeri and Quinn Gleason, are a lower-seeded team whose recent results include a loss to a higher-ranked pair in Washington, limiting their momentum. No confirmed injuries or late roster changes affect either side, leaving the favorites’ superior recent form, head-to-head pedigree, and seeding advantage as the primary drivers of current market positioning.
