In four games this season, the Golden State Warriors and Sacramento Kings showed in just about every way how much of a difference there is between the NBA's Northern California clubs. Stephen Curry had 23 points and nine assists, and the Warriors rode a 23-0 spurt in the first half to beat the Kings 121-96 on Tuesday night, sweeping the season series for the second straight year. We always come out with a win,'' said Warriors reserve Marreese Speights, who finished with 17 points and eight rebounds before fouling out. Golden State shut down Sacramento for more than seven minutes at the end of the first quarter and start of the second quarter to take an 18-point lead.
