The Indiana Fever star attracted a lot of attention towards golf.While Clark has an immense love for the sport, the Masters Tournament is extra special for her."Honestly, I would probably put it number one," Clark said in April, via "Under The Umbrellas." "And I think it's just so different than anything else."While mobile phones have become a person's extension, for Clark, the Masters is refreshing. No one is allowed to carry their phone or camera during the event or they'll face a ban."There's really just nothing like this, and I think the aspect of not having your phone is so unique," Clark said. "Like, you can tell that everybody is so invested, and they're really just there to watch the greatness of the athletes. There's just a peacefulness about it."Clark is recovering from her groin injury to return before the playoffs. However, in the offseason, it won't be surprising if cameras catch her swinging her golf club.
