Women’s singles final set

The ball landing at Barbora Krejcikova’s feet on match point appeared to come down behind the baseline. The linesman thought so and called the shot long.

A TV replay confirmed as much, and the unseeded Krejcikova was so sure she raised her arms in triumph to celebrate a berth in her first Grand Slam final at the French Open.

Chair umpire Pierre Bacchi disagreed. He reversed the call, briefly delaying Krejcikova’s victory.

Tennis was spared an unjust result five points later, when she hit a backhand winner to close out the biggest victory of her career. The Czech saved a match point midway through the final set and outlasted No. 17-seeded Maria Sakkari of Greece 7-5, 4-6, 9-7.

Her opponent Saturday (9 a.m. ET, NBC) will be 29-year-old Russian Anastasia Pavlyuchenkova, who also advanced to her first major final by beating unseeded Tamara Zidansek 7-5, 6-3.
