James became the youngest player to reach 20,000 career points when a pull-up jumper in the lane caught both David Lee and Klay Thompson off guard and vaulted the 28-year-old yet again into the annals of NBA history.
Miami (25-12) held the Warriors (23-14) to just 38 points in the first half on 37.5 percent shooting, including just 1-for-6 from the three-point line. The Warriors turned the ball over 13 times in the half and never managed to recover.
The Heat were dominant in transition from the onset, scoring 22 fast break points. Their athleticism translated to the defensive end where they held the Warriors to 36.2 percent from the field.
