Las Vegas ? With LeBron James out, Dwyane Wade proved he definitely is back. Wade stepped into the starting lineup and scored 20 points in his first action in more than four months, and the United States beat Canada, 120-65, on Friday night in the opener of its exhibition schedule.

James, the NBA’s leading scorer, missed the game because of a mildly sprained right ankle, but the Americans have plenty of offense without him. Carmelo Anthony and Michael Redd also finished with 20 points, and Kobe Bryant added 15.
