Celtics  point guard Rajon Rondo  will be added to the Team USA tryout roster for the 2010 World Championships. Rondo had asked to be left off the roster because of a family commitment, but he appears to have changed his summer plans. He will join 21 other players who will be fighting for a roster spot when they attend the team’s July 20-24 training camp in Las Vegas.
“We got confirmation [Saturday night] that Rondo will come,” USA Basketball chairman Jerry Colangelo told AOL FanHouse. “We’re very pleased to have Rondo with us. He’s very enthusiastic [about representing Team USA]. We feel very comfortable with where we’re at.”
The only player to be guaranteed a spot thus far is Thunder forward Kevin Durant . Rondo will have some stiff competition at the point guard position as he goes up against Chauncey Billups , Russell Westbrook  and Stephen Curry as well as the two most recent Rookies of the Year in Tyreke Evans  and Derrick Rose .
The entire roster from the gold medal team at the 2008 Olympics, including Kobe Bryant , LeBron James , Dwyane Wade  and Dwight Howard , will not be participating this time around for a variety of reasons, ranging from injuries to a hectic summer schedule.
The roster needs to be trimmed to 12 by Aug. 26 for the start of the event in Turkey.
