Network Ten's Big Bash claimed a ratings win against the Australian Open's on Monday, demonstrating again why commercial networks are lining up to secure BBL broadcast rights next summer.

Session two of the Hobart Hurricanes' win over the Brisbane Heat garnered an average viewership of 794,000 in capital cities, while the first half of the match was watched by an average of 667,000 individuals.

That put the BBL clear of Network Seven's opening night session of the tennis, which averaged 589,000 viewers on its main channel.

It is worth noting, however, that Seven splits its tennis broadcast over multiple channels. Seven Mate shows different matches to the main channel, while Seven Two takes over when the news is broadcast from 6-7pm.
