ADELAIDE, Australia (AP) — The captains and coaches were unanimous in endorsing the concept of day-night test cricket, with a few tweaks. The domestic TV audience peaked at almost 3.2 million as Australia closed in on a three-wicket win on Sunday night, a clear ratings winner for the game. The thing about day-night test cricket is it is meant to allow test match cricket to be played at night time — it is not meant to be to change how test cricket should play. The day-night concept has support from a collection of cricket administrators and broadcasters keen to restore global interest in the traditional five-day format at a time when Twenty20, the shortest version of cricket which usually is played in prime time TV slots, is growing in popularity. The novelty of it being the first ever day-night test match no doubt helped with ticket sales and TV audiences for the Adelaide match, but people such as Australia coach Darren Lehmann are certain it's the kind of idea that can reinvigorate the longest and most elite form of cricket.
