Solana Sierra vs Sloane Stephens — R128 — Canadian Open

The return game settled it: Sloane Stephens won five of ten return games to Solana Sierra's two of nine, converting 5 of 8 break points against a serve that landed half its first balls and leaked eight double faults. By the rankings — WTA No. 307 over No. 86 — it goes down as an upset, though the betting market had made the qualifier a 53 percent favorite. Sierra's break for 3-1 in the opener came straight back in game 5, another in game 7 for 4-3. Sierra saved a match point and broke for 4-5 in the second, but Stephens answered in game 10, ending it 69 minutes in for a spot in the Canadian Open round of 64.
