Tiebreaker scoring is measured in points (e.g., 1, 2, 3, etc.). In the event two players or teams are tied 6-6 in a set, the tiebreaker set goes to the side who reaches seven points first with a winning margin of at least two points.

Wimbledon's No. 4 seed in the men's bracket, Jack Draper, is the latest seed to fall in the opening two rounds of the grass-court Grand Slam. He shouldn't feel too bad, though. The women have lost seeds 2, 3, 4 and 5, among many others. The men have lost 3, 4 and 5.

Wimbledon is the last Grand Slam to play 64 matches on its first day. That's worse for revenue, but better for tennis.
