The WTA profiled another one of their player's off-court initiative, this time trailing CoCo Vandeweghe as she hung out with Corey Reich. Reich was diagnosed with ALS—a progressive motor neuron disease that affects nerve cells and weakens the muscles—at the age of 21.

"It's just really hard to see people go through that kind of struggle," Vandeweghe said. "It's been amazing to see how upbeat he is about still working and trying to improve himself with the capabilities that are against him."

Reich joined his high school team as the assistant coach, saying it has given him purpose in life for the past 11 years. Vandeweghe spent some time at Reich's Piedmont High School and helped raise $10,000 for ALS research during a fundraiser on his behalf. The four courts at the school were named after Reich in August of this year.
