It's All-Ireland quarter-finals day in the hurling championship with a double-header of senior action at Semple Stadium on the cards.
First up, at 2 o'clock, Dublin and Waterford square-off for a place in the last four.
Dublin's win over Limerick in the last round will have given the capital's hurlers a boost, while Waterford went down to Tipperary in the Munster final
Speaking ahead of the game, Jamesie O'Connor said this Dublin side have enough Championship game time in them to take control of the match.
Dublin make four changes to their starting lineup.
Cian O'Callaghan and Joey Boland will start in defence as Niall Corcoran and Shane Durkin miss out.
Dotsy O'Callaghan is rewarded for his goal in the last round with a start – he's in for Eamon Dillon.
And Niall McMorrow takes over from Daire Plunkett at midfield.
Derek McGrath has made half as many changes.
Darragh Fives and Shane Bennett are in for Eddie Barrett and Stephen Bennett respectively.

The 4 o'clock match sees Galway go up against Cork.
Galway's record in this fixture will provide a lot of hope as they've won the last three Championship matches between the sides.
But the sides come into this game on opposite trajectories – Cork have won back-to-back matches in the qualifiers, but Galway are still licking their wounds from the Leinster final defeat to Kilkenny.
Teenager Conor Whelan will make his full debut for Galway – he was part of the county's minor set up last year and intermediate team this season.
His inclusion is one of two changes made to Anthony Cunningham's side, Jason Flynn returning to full fitness and the starting line-up.
Fergal Moore and David Glennon drop to the bench.
Cork have fully-fit squad for the first time this year and opt to make just the one change as Shane O'Neill replaces Alan Cadogan.

It's not just senior action in Thurles, though.
The curtain-raiser sees Limerick and Galway face off in the minor quarter-finals.
That's underway at midday.
There's also the under-21 hurling Championship 'C' final, which sees Donegal take on Tyrone at Celtic Park from 6.
