Caroline Wozniacki, the newly crowned Nature Valley International champion, was looking for her second-ever Grand Slam title when she began her campaign at Wimbledon this week – and she also had a chance of once again becoming World No.1.

After her 6-4, 1-6, 7-5 loss to Ekaterina Makarova in the second round, though, that ensures that Simona Halep will come out of the tournament on top of the rankings.

“I think I have been playing well for a while now, so I don't know,” Wozniacki had told reporters in Eastbourne when asked if she thought she would return to the top spot after Wimbledon. “It just went well this week - and I'm going to take it and not overthink things.”

During Wimbledon, current No.1 Halep will extend her stay at the top of the rankings to 36 of the last 40 weeks - including the 20 consecutive weeks since February 26, 2018.

Wozniacki, the reigning Australian Open champion, needed to reach the final in order to have a chance of overtaking the Romanian in two weeks' time.

The 27-year-old was World No.1 for four weeks following her title win in Melbourne earlier this year, and has settled in second spot since then.

Before the tournament, US Open champion Sloane Stephens also had a chance of becoming World No.1 – but she needed to win the title with Halep losing in the first round and Wozniacki getting knocked out before the final.

The permutations became theoretical anyway as the American lost in the first round to Donna Vekic in straight sets, 6-1, 6-3, despite currently enjoying a career-high ranking of World No.4.

Garbiñe Muguruza, the World No.3, will not be able to return to the top spot even if she successfully defends her Wimbledon title.
