Juncheng Shang vs Andrey Rublev — R64 — Canadian Open

Conversion, not creation, separated them at the Canadian Open. Juncheng Shang cashed 4 of 7 break points while Andrey Rublev, a 73 percent favorite with the betting market, converted 4 of 15 — just 1 of 9 across the third set. Rublev out-aced him 12-5 and won 75 percent of first-serve points but leaked 68 unforced errors, and the 21-year-old from Beijing saved five match points before taking the final-set tiebreak. At 2 hours, 43 minutes, it stands as Shang's second top-15 win on record, after his win over Karen Khachanov in Shanghai last October.
