NEW YORK (AP) -- The preliminary television rating for Game 5 of the NBA finals was up 25 percent from the last time the same teams met in the championship series.

The Dallas Mavericks' 112-103 win over the Miami Heat on Thursday on ABC drew a 12.6 overnight rating. Game 5 in 2006 earne a 10.1.

The rating was down slightly from the 12.8 for the fifth game of last season's Celtics-Lakers series, the only higher Game 5 rating for the last seven years.

Ratings represent the percentage of all homes with televisions tuned into a program. Overnight ratings measure the country's largest markets.
