"These Games will see the introduction of new and additional competitions at the Summer Olympics, including 3x3 basketball, freestyle BMX and Madison cycling, as well as further mixed events. Under new IOC policies that allow the host organizing committee to add sports to the Olympic programme to augment the permanent core Olympic events, these Games will see karate, sport climbing, surfing and skateboarding make their Olympic debuts, as well as the return of baseball and softball for the first time since 2008."

So, who's on the US team?? Can any other country compete given this smaller format, played on a half-court?
