According to the Daily Mail, Vonn stayed inside Woods' black Mercedes for an hour while he went to watch his daughter Samantha, 5, play ball, reportedly to avoid running into the golfer's ex-wife, Elin Nordegren, who was also at the game.
Woods and Nordegren, who divorced in 2010, sat at opposite ends of the stadium.
Nordegren is reportedly dating billionaire Chris Cline.
