Five standouts from the U.S. Under-18 national team

The U.S. Under-18 national team is undefeated so far entering Tuesday night's semifinal matchup with Canada. Here's a look at five players who have stood out in the first three games of the competition:

1. Quincy Miller, F, Class of 2011

Stats: 17.3 ppg, 9.3 rpg, 24.7 mpg

College choice: Undecided

Outlook: Here's all you need to know about Miller: John Wall traveled to San Antonio to watch him play. The 6-foot-8 Miller, a North Carolina native like Wall, has been outstanding off the bench for the U.S. team, shooting 20 of 27 overall from the field and breaking the tournament record with 17 rebounds in the U.S.'s opening victory over the Virgin Islands. He also had 22 points against Argentina on Monday.

2. Kyrie Irving, PG, Class of 2010

Stats: 11.7 ppg, 3 apg, 4 rpg, 16 mpg

College choice: Duke

Outlook: Irving has received more hype than any Duke incoming freshman in recent years, but the New Jersey native has backed it up in San Antonio so far. He's started at point guard, established himself as a team leader and committed only three turnovers in the whole tournament so far. Irving's best game so far? How about 25 points on 10 of 16 shooting in a scrimmage against the U.S. U-17 squad?

3. Austin Rivers, SG, Class of 2011

Stats: 15.7 ppg, 1.3 apg, 20.3 mpg

College choice: Florida, Duke, North Carolina, Kentucky, Kansas, UCLA

Outlook: Rivers, the son of Boston Celtics coach Doc Rivers, has shown why he'll be one of the top recruits in the nation next year. He's the second-leading scorer on the U.S. team behind only Miller, shooting 52.9 percent from the floor in three games and hitting 9 of 17 from behind the three-point arc.

Jereme Richmond, F, Class of 2010

Stats: 11.3 ppg, 7.3 rpg, 3 apg

College choice: Illinois

Outlook: When Richmond committed to Illinois after his first varsity game as a high school freshman, the Illini could not have known how well this was going to work out. The 6-foot-6 McDonald's All-American has been the U.S. team's most versatile player, contributing consistent scoring, rebounding and even coming up with four steals.

5. Tony Mitchell, F, Class of 2010

Stats: 8.7 ppg, 8 rpg, 16 mpg

College choice: Missouri

Outlook: It remains to be seen whether Mitchell will actually be academically eligible to enroll at Missouri in the fall, but the 6-foot-8 forward is showing he's capable of making an immediate impact on the glass. A team-high eight rebounds a game are especially impressive when you consider Mitchell is doing it off the bench while averaging 16 minutes.

Worth noting: Washington sophomore-to-be Abdul Gaddy, the only player on the team with college experience, has contributed a team-high 11 assists ... David Robinson said that Florida-bound big man Patric Young is better than he was at the same age ... Marquette-bound Vander Blue and Duke-bound Josh Hairston have started every game alongside Irving, Rivers and Young.
