Coco Gauff retired from her third-round match at Indian Wells on Sunday with a “scary” left arm injury that “felt like it was on fire” but was optimistic she could sort out the problem in time to play in Miami.

The 21-year-old world No. 4 was trailing Alexandra Eala 6-2, 2-0 when the American called it a day, sending the rising star from the Philippines into the last 16.

“I felt it, like, the second game of the first set,” Gauff said. “I guess a simple way to put it, it felt like a firework was going off inside of my arm, and then my whole arm felt like it was on fire.
