Maria Sakkari vs Zeynep Sonmez — R64 — Canadian Open

The return pressure never let up. Maria Sakkari took half of her eight return games while Zeynep Sonmez managed one of eight, and the lone wobble — a break conceded in game 3 of the opener — was answered in game 4 before Sakkari ran off the rest. The 29th seed closed in 1 hour, 19 minutes, Sonmez saving two match points first, and now leads their meetings on record 2-1.
