Galway's starting line-up shows two changes ahead of their Leinster semi-final clash with Offaly in Portlaoise.
Until Wexford hogged all the headlines with their victory over Kilkenny last Saturday evening, Galway were regarded as the form team in the hurling championship.
The westerners won handsomely against Dublin in the Leinster quarter-final in Tullamore at the end of May. Notwithstanding this triumph, the starting line-up this weekend shows two changes.
One of those changes is enforced as John Hanbury replaces Paul Killeen, who was struck down with a cruciate ligament injury in the first half of the Dublin game.
Niall Burke was introduced late against Dublin and whipped over 0-2 from play in quick succession. His reward is a starting berth in the half forward line in place of Joseph Cooney.
Offaly bring two new faces in after their defeat of Westmeath last time out.
Paddy Murphy comes in to midfield in place of Aidan Treacy, and Joe Bergin replaces Peter Geraghty in the half-forward line.
Galway (Leinster SHC v Offaly): C Callanan; A Touhy, D Burke, J Hanbury; P Mannion, G McInerney, A Harte; J Coen, D Burke (capt); J Flynn, J Canning, N Burke; C Whelan, C Mannion, C Cooney
Offaly: James Dempsey; Ben Conneely, Dermo Shortt, Enda Grogan; Sean Ryan, Sean Gardiner, David King; Paddy Murphy, Shane Kinsella; Padraic Guinan, Joe Bergin, Emmett Nolan; Sean Cleary, Shane Dooley, Oisin Kelly.
Michael Walsh hits a milestone for Waterford in their Munster SHC semi-final with Cork on Sunday, as he gears up for his 65th championship appearance .
He starts at full-forward as the Deise finally get their summer started, and will match Tony Browne's record when he lines out in Thurles.
The same Cork starting XV who stunned Tipperary in Semple Stadium last month will start for Kieran Kingston.
There had been doubts about the Man of the Match against Tipp, Conor Lehane, after he suffered ankle damage in training.
Cork manager Kingston adjudged his chances of involvement as no better than 50/50 during the week.
But Lehane, who hit 0-10 against Tipperary in an inspirational performance, retains his spot at centre-half forward for the Waterford game.
Waterford (Munster SHC v Cork): Stephen O'Keeffe; Shane Fives, Barry Coughlan, Noel Connors; Tadhg de Burca, Austin Gleeson, Philip Mahony; Jamie Barron, Conor Gleeson, Kevin Moran, Pauric Mahony, Stephen Bennett; Shane Bennett, Michael Walsh, Darragh Fives.
Cork: A Nash; S McDonnell, D Cahalane, C Spillane; C Joyce, M Ellis, M Coleman; B Cooper, D Fitzgibbon; L Meade, C Lehane, S Kingston; A Cadogan, S Harnedy, P Horgan.
Mickey Harte has kept faith with the starting 15 who saw off Derry last time out for Tyrone's Ulster SFC semi-final collision with Donegal this Sunday (2pm).
The Red Hands eased to a 0-22 to 0-11 victory at Celtic Park nearly three weeks ago to set up the Clones face-off.
Captain Sean Cavanagh was terrific that day, notching seven points, and he again leads the line.
Donegal had little trouble in progressing themselves, powering past Antrim 3-19 to 1-09 in Ballybofey.
Tyrone: N Morgan; A McCrory, R McNamee, P Hampsey; T McCann, R Brennan, P Harte; C Cavanagh, C McCann; K McGeary, N Sludden, C Meyler; M Bradley, S Cavanagh (capt), M Donnelly.
Leitrim are unchanged from the team that beat London for their Connacht SFC semi-final earlier in the week.
Roscommon took the unusual step of naming their team on Monday.
Kevin McStay will give Championship debuts to goalkeeper Colm Lavin, midfielder Tadhg O’Rourke (Tulsk) and half-forward Brian Stack.
Roscommon: Colm Lavin; David Murray, John McManus, Niall McInerney; Sean McDermott, Sean Mullooly, Conor Devaney; Tadgh O’Rourke, Enda Smith; Fintan Cregg, Niall Kilroy, Brian Stack; Ciarain Murtagh, Diarmuid Murtagh, Donie Smith.
Leitrim: Brendan Flynn; Michael McWeeney, Ronan Gallagher, Paddy Maguire; James Rooney, Donal Wrynn, Oisin Madden; Shane Moran, Damien Moran; Brendan Gallagher, Dean McGovern, Ryan O’Rourke; Keith Beirne, Conor Gaffney, Darragh Rooney.
Roscommon (Connacht SFC v Leitrim): Colm Lavin; David Murray, John McManus, Niall McInerney; Sean McDermott, Sean Mullooly, Conor Devaney; Tadgh O’Rourke, Enda Smith; Fintan Cregg, Niall Kilroy, Brian Stack; Ciarain Murtagh, Diarmuid Murtagh, Donie Smith.
