CLEVELAND - - LeBron James piled up 23 points, eight assists and seven rebounds in just three quarters and the Cleveland Cavaliers rolled to a 121-98 win over the Washington Wizards, who watched troubled guard Gilbert Arenas leave them indefinitely on Wednesday.

Shaquille O'Neal added 17 points in 17 minutes as the Cavs posted a season high for points and won for the 13th time in 15 games.

The Wizards played for the first time this season without Arenas, who was suspended indefinitely without pay a few hours before the opening tip by NBA commissioner David Stern. Antawn Jamison scored 26 points and Randy Foye 18 for the Wizards. Earl Boykins started for Arenas.

The Cavs exploited a size mismatch in the second quarter by pounding the ball inside to O'Neal, who scored 13 points in the period to give Cleveland a 22-point halftime lead.
