Fritz and Mpetshi Perricard’s match, by contrast, was at the mercy of the most sacred and strange tradition of them all: the 11 p.m. curfew imposed on a sporting event beamed across the globe.

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.

Highlights of the sixth day at the Wimbledon tennis championships on Saturday (times GMT): 1010 PLAY UNDERWAY Play began under overcast skies at the All England Club, with the temperature hovering around 20 degrees Celsius (68°F) and expected to climb to 21 degrees Celsius later in the day.

Wimbledon started like it does every year, with 64 seeds across the men’s and women’s singles draw. As the third round begins, just 27 remain — 14 women and 13 men. It’s the fewest at a Grand Slam since the 32-seed format was first adopted in 2001.
