Alexis Galarneau vs Vit Kopriva — R128 — Canadian Open

First-serve points decided a five-hour, 19-minute slog at the Canadian Open. Vit Kopriva won 74 percent of them (29 of 39) against Alexis Galarneau's 55, a cushion that held up through six combined breaks of serve. The last of those breaks landed in game 5 of the second set, the ATP No. 70 reclaiming the lead for 3-2 one game after a break-back had leveled it at 2-2. The finish alone took six match points. Galarneau, a wild card the betting market had narrowly favored at 51 percent, saved five of them and converted break points at the sharper rate, 2 of 4 against Kopriva's 4 of 10, though the first-serve deficit never closed. The sixth landed, worth a first win since late June that ends a four-match slide.
