On Sunday, ESPN showed a picture of Halep in the hospital during its airing of the men's final between Roger Federer and Marin Cilic. The network reported she received four hours of treatment before getting released, per WTA Insider.
Halep, who entered the season's first major as the top-ranked player in the world, was forced to battle her way through the entire event.
ESPN Stats & Info noted the 153 games she played through the first six rounds were the most by a women's No. 1 seed who reached the championship match in the Open Era.
She proceeded to play 32 more in a hard-fought defeat against Wozniacki, who will become the new world No. 1 after capturing her first Grand Slam title.
Afterward, the 26-year-old Romanian star admitted she didn't have enough energy left to end her own major drought, which reached 31 career appearances without a triumph.
"The body was not ready because I had so many long matches," she told reporters. "The muscles were tired. The feet were not good enough. But mentally I was ready. I feel that I can face any challenge. I can play against anyone. I can win against anyone."
The next Grand Slam event, the 2018 French Open, doesn't begin until late May. Halep should be back to full strength long before it starts.
