Before this match concludes - before the joy of victory or the misery of defeat can color my judgement - I offer some thoughts on what this Test means for the future of the long-form game.
Women's Test cricket is in a bad way. In the past 5 years, just 4 Tests have been played, all of them between England and Australia; and you have to go all the way back to 2007 to find the last Test involving any of the other nations*.
And it wasn't just the quantity that was at issue, it was the quality too. As the game at Wormsley last summer petered-out into a bore-draw I found myself privately questioning whether the format had any future at all.
But now... oh boy! The past three days has been the most joyous sporting spectacle I've witnessed in many-a-year.
Yes, we've seen four (count 'em!) insane batting collapses, but they've been driven by quality bowling from the likes of Perry and Cross; and what's more, on three occasions so far, we've then seen the game subsequently wrestled back into balance, with bravery and fortitude from Brindle, Perry and Edwards.
By this time tomorrow, someone will have won and someone will have lost. Eleven women and their fans will be in heaven, while eleven other women and their fans will be somewhere else entirely!
One thing is for sure though - we may never see another Test that doesn't involve England and Australia... but this game has guaranteed that Ashes Tests are here to stay!
(Though possibly with slightly fewer points attached! Somewhat counter-intuitively, the very closeness of this game makes it even less likely that the losing side can come back to win the series, due to the devastation they will inevitably feel in the wake of their defeat.)
