(Reuters) -Kai Trump, the eldest granddaughter of U.S. President Donald Trump, made her LPGA debut on Thursday at Pelican Golf Club in Belleair, Florida, where she struggled en route to posting the day's highest score.

The 18-year-old amateur, who received a sponsor's exemption to play The Annika, opened with a 13-over-par 83 that left her in last place at an event chock full of the game's top talent and by far the biggest tournament of her career.
