The NBA finals are slam-dunking the Braves on Atlanta television.

ABC’s coverage of the first four games of the Miami Heat-Dallas Mavericks series has drawn a 12.9 rating in the metro Atlanta TV market, meaning 12.9 percent of the area’s TV households have tuned in on average.

The local ratings were 11.8 for Game 1, 12.8 for Games 2 and 3 and 14.3 for Game 4.

By comparison, the Sunday and Tuesday Braves games, which aired partly overlapping the NBA, drew Atlanta ratings of 3.4 and 3.1 on ESPN and SportSouth, respectively. The first three games of the NHL finals between the Boston Bruins and Vancouver Canucks drew Atlanta ratings of 1.3, 0.6 and 0.3 — the first two games on NBC and the third on Versus.

The NBA finals ratings in Atlanta are significantly higher than the national average of 9.2 through four games. Atlanta ranks ninth among the 56 metered markets. The top three markets — Miami, Dallas and West Palm Beach, Fla. — and five of the top 10 are in Florida and Texas.

Atlanta’s 12.9 rating translates to an average audience here of about 310,000 households.
