MELBOURNE -- Caroline Wozniacki became the first Grand Slam champion from Denmark as she claimed the biggest victory of her career with a 7-6 (7-2), 3-6, 6-4 defeat of Simona Halep on Saturday to win the Australian Open.
The 27-year-old, who was denied trophies in 2009 and 2014 at the U.S. Open, will move back to the No. 1 ranking that she held for a total of 67 weeks during two periods in 2010 and 2011.
Halep, who will lose the top spot on Monday, remains without a Grand Slam title.
Wozniacki now owns 28 career trophies, including the WTA year-end championships crown from last season.
"She was playing really well, but I was not nervous. I felt it could go my way," Wozniacki said. "It was a tough grind and we battled.
"I'm happy I won the title. It's a very special moment.
"When I saw that ball go into the net (on match point) it was wow, crazy emotional."
Both women needed on-court treatment in a match that was paused for 10 minutes at the end of the second set due to the heat rule in effect.
Halep had her blood pressure taken midway through the second set, but returned to the court without any treatment. She also looked to be cramping.
"I had a little cramp -- that went away. But the pain remained a little bit till the end," she said.
