BASKETBALL COURT TO TENNIS COURT
Dirk Nowitzki, Steve Nash and Luka Doncic ditched basketballs for rackets this weekend -- hitting tennis courts in Dallas for charity -- and it turns out the trio of hoopers have no issues whatsoever channelin' their inner-Serena Williams!!
The Dallas Mavericks icons -- plus Ben Stiller and a whole host of other celebs and athletes -- all competed in the fifth annual Dirk Nowitzki Pro Celebrity Tennis Classic on Sunday .
