So, who's through to the World Cup?

As things stand, only West Indies have sealed their spot in next year's World Cup. They will finish top of the Super Sixes table with eight points, irrespective of how Friday's game between Afghanistan and Ireland goes.

Zimbabwe, who are currently on the second qualifying spot despite a narrow defeat at the hands of UAE, are all but out of World Cup contention.

Does that mean Zimbabwe still theoretically hold a chance of qualifying?

Yes, it is quite a slender chance though. Zimbabwe will need the match between Afghanistan and Ireland to finish as a tie, which would bring down Ireland's Net Run Rate down to 0.377, which is less than their NRR of 0.420.

What do Ireland and Afghanistan need to do to qualify?

Simple, win their final Super Sixes game, where they face off against each other on Friday. It is a knockout clash for all practical purposes, with the winner moving up to six points and qualifying for the final, and more crucially, taking the 10th and final World Cup spot.

What happens if Friday's game is washed out?

In that case, Ireland, who currently sit at four points and a superior Net Run Rate to Zimbabwe's, will go through, since a washout will have no impact on their NRR.
