It comes down to the final round of matches to decide which teams will qualify for the Super Six stage of the ICC Women's World Cup India 2013.
Group A is closely bunched, with all four teams having a chance of making it to the next round of the biggest competition in women's cricket.
All four teams - defending champion England, host India, Sri Lanka and West Indies - are on equal points, with a win each from two matches.
On Tuesday, India takes on Sri Lanka at the Cricket Club of India in a day-night game that starts at 1430 in front of Star Sports' cameras, while England takes on West Indies at the MCA Recreation Centre at Bandra Kurla Complex (BKC) from 0900.
The winning sides will qualify for the Super Six stage, while net run-rate will decide which of the two losing sides progress to the next round.
On the eve of the deciding group matches, West Indies is in pole position in terms of run-rate thanks to its decisive 209-runs win against Sri Lanka at the MIG Ground on Sunday, bolstering its run-rate to a healthy +1.040.
That loss has affected Sri Lanka's run-rate adversely, and it is placed fourth with a run rate of -2.030.
India is second in the group with a healthy net run-rate of +0.730, while England is third with +0.260.
All four teams would take comfort from the fact that their destinies lay in their own hands, as a win will ensure progress.
The equation in Group B is much more straightforward. Current group leader New Zealand and second-placed Australia are on two wins from two games, having each beaten Pakistan and South Africa.
Both will therefore qualify for the Super Six stage. The two teams lock horns in Cuttack on the DRIEMS Cricket Ground on Tuesday from 0900.
Both sides will be looking to end the Group stage on a high, as teams that progress to the Super Six stage carry forward points from Group stage matches won against other sides that also advance.
Pakistan and South Africa play a virtual shoot-out at the Barabati Stadium from 0900 on Tuesday.
With both sides having lost their opening two games, the match will be a keenly fought contest to stay afloat in the tournament.
Pakistan currently sits in third place in Group B with a net run-rate of -1.672, while South Africa is in fourth with -1.761.
Teams finishing last in both groups will meet for a seventh place play-off on Feb 7.
