FLUSHING MEADOWS, N.Y. — This is the kind of day Tuesday was for Dover’s Madison Brengle.

Late in the second set of her first-round U.S. Open match at the Billie Jean King National Tennis Center, she crushed a forehand deep into the court that her opponent, Shelby Rogers could only return feebly.

Brengle approached the net and had two choices on a finisher. She chose crosscourt, and Rogers happened to guess that way, too. And Rogers blocked Brengle’s finisher back down the line past her.

Brengle could only look at the fortunate reply in disgust, but it symbolized the way the last 30 minutes of the match went.

After a strong start, it all went south for the 31-year-old on Court 5, as Brengle’s Grand Slam singles season came to an end with a 6-4, 6-0 defeat.

“She did everything just about perfectly,” Brengle said. “I had some chances in the first set, but she played super well and made some great shots.”

The match started strongly for Brengle, ranked No. 77 in the WTA rankings coming into the Open. She broke serve early and lead 2-0, and then after the South Carolinian Rogers won four straight games to go up 4-2, Brengle broke back and held for 4-all.

At that point, it looked like it would be a grinding three-set match, the kind Brengle excels in.

But Rogers, ranked 43rd and a quarterfinalist at last year’s fan-less U.S. Open, just took her game to another level. She began dictating play with her forehand and forcing the Delawarean into defensive shots, and Brengle began spraying the ball a bit.

Once Rogers broke Brengle after a double fault to go up 2-0 in the second, the outcome seemed no longer in doubt.

“I felt pretty good out there, I just wasn’t able to get momentum in the second set, and she wasn’t making errors,” Brengle said.

It was a disappointing end to what has been a pretty good year at the Slams for Brengle.

She reached the third round at Wimbledon in July, knocking off Top 5 Sofia Kenin along the way, and reached the second round at both the Australian and French Opens.

Brengle said she appreciated having the good health to play in all four Slams this year, and having spectators back cheering was another plus.

“It was really nice having the fans there today, we haven’t had full crowds in a while,” Brengle said. “It was great to hear the noise from them.”

With the $75,000 prize money from the Open, she’s now earned $518,000 on the tour this year.

Brengle will compete in the doubles draw with fellow American Claire Liu; their first match is Wednesday at 11 a.m.
