NEW YORK (AP) The Latest on the U.S. Open tennis tournament (all times local):

3:40 p.m.

Could the U.S. Open have set the stage for the end of line calls by human officials?

Tournament director Stacey Allaster said before the men's final Sunday that the use of electronic line-calling instead of line judges for all courts other than the two largest stadiums went well.

"It's been a terrific success. There's no debate," Allaster said.

She added: "We couldn't be more pleased with how it has been executed."

Allaster said no decision has been made about using the Hawk-Eye Live system in 2021 for all calls at the Grand Slam tournament she oversees.

Only matches played at Arthur Ashe Stadium and Louis Armstrong Stadium had full complements of line judges aiding the chair umpire.

It was during a match in Ashe that No. 1 seed Novak Djokovic angrily smacked a ball that accidentally hit a line judge in the throat after a game. Djokovic was disqualified.

As the first Grand Slam tournament amid the coronavirus pandemic drew to a close, U.S. Tennis Association CEO Mike Dowse said of the fan-less event: "It's safe, it's been good for tennis, and it's been financially good for the players and the tennis ecosystem."

3:20 p.m.

Dominic Thiem and Alexander Zverev are set for the U.S. Open final, with the winner giving men's tennis its first new Grand Slam champion in six years.

Marin Cilic's U.S. Open title in 2014 was the last won by somebody who hadn't previously won a major singles title.

Thiem, the No. 2 seed, is in its fourth opportunity to win one. The Austrian lost two French Open finals to Rafael Nadal and fell in this year's Australian Open final to Novak Djokovic.

The fifth-seeded Zverev is in his first Grand Slam final. He had to win a five-setter in the semifinals so he should be helped by cloudy, comfortable conditions in New York on Sunday.
