No. 2 seed Caroline Wozniacki began 2018 in historic fashion winning her first Grand Slam title at the Australian Open. She ended it at the new jinxed Armstrong Stadium.

The Great Dane was bounced out of the second round in a 6-4, 6-2 night-card defeat to Ukraine’s 36th-ranked Lesia Tsurenko on Armstrong’s night card. It wasn’t shocking, but it was surprising as Tsurenko took advantage of too many Wozniacki short balls.

The new venue has been disruptive for top-seeded women — with No. 1 Simona Halep losing in its first-ever match on the court and 2-time Grand Slam champion Garbine Muguruza being stunned at 1:03 a.m Thursday by 202nd ranked Czech qualifier Karolina Muchova.

“Wimbledon used to have a Graveyard Court — maybe this is going to be the new Graveyard court,” Wozniacki said.

Nevertheless, Wozniacki, whose engagement to ex-Knick David Lee coincided with her Australian triumph, said she doesn’t believe her early Open exit diminishes her season.

“I’m always going to say it’s a great season because I won my first major,” Wozniacki said. “Regardless of what happens the last few tournaments of the year, it’s still going to be a great year because I won in Australia. If I hadn’t won Australia, we would be talking differently.”

Madison Keys cruised into the third round with a 6-4, 6-1 win in 72 minutes over fellow American Bernarda Pera.

“I feel good. It’s always nice to finish when the sun is still up. I like that,” Keys said with a smile after hitting eight aces and never losing her serve.

“I feel really good about today. I think I definitely brought my game up to a better level in the second set, so happy with it.”

The 14th-seeded Keys reached the finals last year in Flushing Meadows, where she lost to fellow American Sloane Stephens. After her first Grand Slam final, she has largely flown under the radar in a year hampered by injuries.

“Yeah, I got sick after the Australian,’’ she said.

“Then I had an injury in Rome. I mean, it comes with the territory. … I mean, I still had good results throughout the year. I obviously would like to have been able to play more matches, but I can’t change my body, so …”

Keys said she is trying to ignore the pressure of backing up a finals appearance here last year.

“Well, I’m trying not too think of it that way,’’ she said.

“Really just taking it match by match. It’s my first time having to defend a big result like that, so that’s something I’m going to have to deal with every day. The biggest thing is to not put pressure on myself and think it’s a failed tournament if I don’t make the finals or win. For me, it’s doing the things I can do to control the situation, see how things go.”

In the late match at Arthur Ashe Stadium, No. 22 Maria Sharapova worked past midnight and shook off a slew of first-set double faults to oust Romanian Sorana Cirstea 6-2, 7-5 to move to Round 3.

Sharapova fell behind a break in the second set, but rallied and won 10 of the last 11 points. Sharapova faces Latvia’s Jelena Ostapenko next.

Fourth-seeded Angelique Kerber got a brief test before downing Johanna Larsson 6-2, 5-7, 6-4.

“It is tennis that you have to play until the last point. She came back. She played good when she was down, and she had nothing to lose then,” said Kerber.

“The conditions are really tough out there. But at the end, in the third set, it was just like two, three points which decide the match.’
At the end, she was elated.

“Yeah, I was happy that at the end I could serve the match until the end,” she said.

Kerber broke at 4-all in the third set when her Swedish foe double-faulted. Then she served out the match.

The 2016 U.S. Open champion next faces Dominika Cibulkova in a third-round matchup.
