Pistons were no match last night for the Heat in preseason action in Miami with Detroit losing 105-to-78. Dwyane Wade poured in 21 points in 23 minutes while LeBron James totaled 13 points and a game-high eight assists as the Heat looked sharp in their return from a trip to China, where Miami split a pair of exhibition outings last week with the Los Angeles Clippers. Greg Monroe led the Pistons with 15 points as Detroit fell to 2-3 on the preseason.
