The Miami Heat got a huge lift from their bench to defeat the Phoenix Suns 80-71 at the Las Vegas Summer League on Tuesday at Thomas and Mack Center.

Miami had just one starter, Briante Weber, score in double figures, as the reserves outscored the starters 48-32. Michael Carrera scored a team-high 16 points. Weber finished with 11 points, six assists and five steals.

The second and third quarters proved the difference as the Heat (2-1) outscored the Suns 47-30 in that 20-minute stretch.
