The 27-year-old Denmark native is coming off one of her best seasons, which she capped by defeating Venus Williams in the championship match of the 2017 WTA Finals last month.
Wozniacki is one of the top active players without a Grand Slam title on her resume. The former top-ranked player in the world has reached a major semifinal six times, including two trips to the U.S. Open final, but has been unable to reach the pinnacle on the sport's biggest stages.
Meanwhile, Lee is a free agent after playing the 2016-17 campaign with the San Antonio Spurs. He's also made stops with the New York Knicks, Golden State Warriors, Boston Celtics and Dallas Mavericks in a 12-year career.
The 34-year-old University of Florida product has earned two All-Star Game selections and won a championship with the Warriors in 2015.
