ABC dominated Thursday's primetime ratings race with Game 5 of the NBA Finals, which produced the series' top overnight rating to date.
The Dallas Mavericks' victory over the Miami Heat averaged a 12.6 overnight household rating, according to Nielsen, up about 10% from Tuesday's Game 4 for the highest of this series.
Over the last seven seasons, only last year's Boston Celtics-Los Angeles Lakers series (12.8 overnight rating) scored higher.
