And finally tonight, every athlete dreams of making the big play in the championship game. But you don't expect opposing players to help you. Just this weekend, an incredible act of sportsmanship. And ABC's Neal Karlinsky has the two teams who are "America strong." Reporter: When beau Howell took to the court in Saturday's championship high school game between the Trinity classical academy knights and the desert chapel eagles, even though his team was way ahead, the pressure was on. Beau is autistic and serves mainly as the team's manager. But he loves the game, wants to play and made it in nine times this season. But he never made a basket. I know we're supposed to be impartial but, go, beau. And you can hear it already from the Trinity classical fans. They are screaming, beau, beau. Reporter: With fierce competitors all around. What a great show of class and sportsmanship. We're honored. We felt that in our hearts. That's what we're all about. Reporter: They named beau player of the game. But it was really all of these kids who earned it. A win that was "America strong." Neal Karlinsky, ABC news, Seattle.
