All the permutations ahead of today's crucial Munster Championship action

It's a huge day in the Munster Senior Hurling Championship as Waterford, Limerick, Clare and Cork all go into the final day with something to play for.

Two games get underway from 4pm to close out this year's provincial action - Waterford take on Limerick at the Gaelic Grounds in what will be our George Corbett Skoda Big Match, while at the same time Clare make the trip to the already ousted Tipperary.

Here's what needs to happen for all four counties that are still in the hunt.

Waterford:

If Waterford beat Limerick they’ll be in the Munster final. Draw and they’ll finish third. Lose and they’re out of the Championship.

Davy Fitzgerald's men have beaten Cork, drawn with Tipperary and lost to Clare so far.

Limerick:

A win or draw against the Deise will secure them a Munster final spot. Lose and they’ll be looking for an unlikely favour from Tipperary.

If they were to fall short and Clare beat Tipperary, it would leave both them and Cork level on four points but Cork would go through to a preliminary quarter-final in third place by virtue of their head-to-head record against Limerick, who would drop out of the Championship.

Clare:

It’s pretty straightforward for Clare: win or draw with Tipperary and they’ll be assured of a Munster final spot.

If they lose, they’ll need Limerick to beat Waterford to stay afloat as even a draw in that game coupled with a Clare defeat would see Brian Lohan’s side drop to fourth and out of the Championship on scoring difference.

Cork:

A Munster final appears unlikely as it would require Clare to lose to already eliminated Tipperary coupled with a draw between Limerick and Waterford, in which scenario Cork would hold second place on scoring difference and meet the holders in the decider.

Wins for Clare and Waterford would see Cork finish third ahead of Limerick on head-to-head.

The nightmare scenario for Cork is a draw between Waterford and Limerick along with Clare beating or drawing with Tipperary as they would slip to fourth and out of the Championship given that Waterford would have the edge on them on head-to-head.
