LeBron James has a 2-0 series lead for the first time in his 10 NBA Finals.
Anthony Davis also had a huge night with 32 points on 15-of-20 shooting. Miami's Meyers Leonard started in place of center Bam Adebayo, who was out due to a neck injury, but provided little resistance to Davis. L.A.'s All-Star big man scored 15 of his 32 in the third quarter, shooting 7-of-9.
James cooled in the fourth as the Heat attempted to make a late run, but added 10 points in the final period to help put the game away.
The Lakers again had success attacking the Heat's zone defense, going 33-for-50 on 2-point shots. Additionally, the team set an NBA Finals record with 47 shots taken from beyond the arc - but only converted on 16.
L.A. is now 20-1 when James and Davis combine for 60 points or more, according to Elias Sports.
