Dallas had been trailing Miami after the first quarter 31-30, but outscored Miami 30-26 in the second quarter en route to taking a 60-57 halftime lead.
The Mavericks are shooting an unbelievable 65.7% from the field (23-35), including 71.4% (5-7) from three point range. Dallas, though, is only 9-14 from the free throw line, with Ian Mahinmi (1-3) and Tyson Chandler (3-5) both missing a pair.
Not surprisingly, Dirk Nowitzki leads the Mavericks with 16 points at the half. Nowitzki is 6-9 from the field with four rebounds and two assists.
Tyson Chandler has been very good in the first half as well, playing 18 minutes going 4-5 from the field for 11 points. Chandler also has three rebounds, a block and a steal.
