The world has applauded as tennis sensation Cori "Coco" Gauff racked up wins.

But there are two people who are not surprised by her success: Corey and Candi Gauff.

After all, this was the plan. “We are on year seven of a ten-year plan. And part of that was at the end of ten years, that she would be holding a Grand Slam trophy,”

Candi is a former teacher who home-schools Coco, even giving a science test during Wimbledon.

“I try to back away on the court, because too many voices can be a crowd,” Candi Gauff said. “I let my husband be the coach, and I’m the supportive mom, the one if she hurts or is crying that she can communicate with.” (NBC News)
