The GAA Championship is reaching boiling point. Last weekend saw Roscommon dismantle Mayo by 10 points, while Cork outlasted 14-man Limerick in a classic at Páirc Uí Chaoimh. Some counties’ seasons are already on the line.

The football championships are reaching the business end, while the Munster hurling round robin continues to serve up some of the best action you’ll see all summer.

Here’s everything you can watch this weekend.

Saturday, May 2

The headline game comes from the Box-It Athletic Grounds in Armagh, where Derry face Monaghan in the Ulster Football Championship semi-final.

Ciarán Meenagh’s side got their campaign off to a flying start a fortnight ago when they hammered Antrim by 13 points. Monaghan, meanwhile, booked their spot with a 0-27 to 2-13 win over Cavan in Clones.

That one is live on GAA+ with throw-in at 5pm.

Saturday night brings another cracker, with Dublin taking on Louth in the Leinster Championship semi-final.

It’s the Dubs’ first meeting with Louth since Ger Brennan departed The Wee County, though he’ll still be serving his suspension this weekend.

Also on GAA+, throw-in at 7pm.

Sunday, May 3

Westmeath will look to build on their shock win over Meath when they face Kildare in the other Leinster semi-final.

The Lake County blew the championship wide open with that victory — can they do it again?

That game is on GAA+ at 2pm.

RTÉ’s cameras head to Cusack Park in Ennis for a blockbuster Munster hurling clash between Clare and Limerick.

The visitors need to bounce back after last Sunday’s dramatic loss to Cork, while Clare started with a win over Waterford and will want to keep the momentum going.

Live on RTÉ2, throw-in at 2pm.

To cap off a massive weekend, Armagh play Down in the other Ulster football semi-final.

Kieran McGeeney’s side advanced after beating Fermanagh, while Down pulled off the shock of the championship so far with a nine-point win over Donegal in Letterkenny.
