National Plate quarter final (2pm):

Crymych v Ystalyfera

It's a huge day for Crymych as they look to take another step towards a historic Principality Stadium final. p>The Preseli Men knocked out holders Penallta 12-7 in the last round, and now face Ystalyfera, who were agonisingly beaten by the latter in the final at the Principality Stadium last season.

That game actually finished 16-16, with Ystalyfera missing out on try count, but the south Wales side have been in great form in this campaign.

In Division One West Central, they sit third in the table with 11 wins and a draw from their 12 games – and have beaten Cwmavon (38-0), Llandudno (16-3), Bonymaen (8-5), and Maesteg (30-3) on their way to the last eight.

But all their ties have been at home thus far – and they will have noted the way The Preseli Men rose to the occasion against Penallta at Parc Lloyd Thomas.

And Randall Williams' side go into this in their best form of the season, having backed up their win in Penclawdd by grinding out a 10-3 victory in Tenby last Thursday.

That night the pack were superb, with second row Osian Davies leading the way in the ball carrying stakes, and I expect Williams will be happy to see heavy pitch conditions again tomorrow.

The Preseli Men will be prepared and fired up, and should have the backing of a large home crowd. Show the same cohesion and passion they did against Penallta and in their recent league games, and they have every chance.

Championship:

Glynneath v Narberth

The Otters have not got going in 2018, only managing three league and cup games due to the weather, and losing all of them.

The latter of those saw them stunned 29-31 at home to Bedlinog after being 17-0 up half time, and their chances of a second consecutive two finish have been dented.

So alarm bells will start ringing if they don't return to winning ways here against a Glynneath side who lie bottom of the table with just two wins in 14 games - and who lost 27-3 in Narberth back in October.

They too have struggled badly since Christmas, having lost heavily three times, the latter of which a 5-41 home defeat to Tata Steel.

For Narberth, James Stephenson returns to the staring XV at full back, while Rhodri Owen is preferred at hooker to the experienced Dan Smith. Rhys Lane and Jonathan Rogers are the chosen half backs - and Sean Gale will want that pairing to control matters as his side seek a first win since December 30th.

Narberth: James Stephenson, Liam Hutchings, Kieran Jones, Paul Davies, Nick Gale, Jonathan Rogers, Rhys Lane, Bradley Davies, Rhodri Owen, Tom Slater, Jake Simm, Alex Jenkins (capt), Dewi Williams, Tom Powell, Steffan Phillips. Replacements: Rhys Davies, Dan Smith, Rich Rees, Lewys Gibby, Ianto Griffiths.

Division One West:

Gorseinon v Tenby United

It is now three straight league defeats for The Seasiders after last week's home loss to Crymych, and the home side would have had few complaints after the visitors dominated possession for long periods.

And it will be tough again tomorrow away to fourth placed Gorseinon, who themselves were edged out 15-9 at Gowerton in their last match.

Tenby are likely to be without Jonathan Rogers and Tom Slater after both came in on permit from Narberth for the Crymych defeat, and will have to decide whether to start Pat Roberts in the back row or the centre, having been effective in both roles this season.

The Seasiders are safe from relegation, but Chris James' side still have a Pembrokeshire KO Cup semi final to play in Aber, and the head coach will not want his side going into that on the back of a winless run.

Therefore, a return to form here against a team they beat 13-6 in December, would be timely.

Division Two West:

Amman United v Whitland

The Borderers were at their best in hammering Loughor 46-7 last Friday night as winger Sean Coles starred with four tries, but they will be in for more of a dogfight tomorrow.

Amman are in the bottom two and fighting for their lives, and will be scrapping for everything against a Whitland team whose title destiny is still in their own hands.

Gareth Bennett and Dan Mason's men are 11 points off leaders Yr Hendy, but with three games in hand, and must keep the pressure on tomorrow.

The coaches make one change to the backline that dismantled Loughor, with Scott Lloyd coming into the centre on permit and Jonathan Thomas switching to full back, with Scott Newton now unavailable.

In  the pack, Kevin Allen replaces Gethin Lewis at No 2, and in the back row Ryan Morgan starts at openside flanker with Danny Evans dropping out.

The Borderers will have to match the commitment of the home side up front, and they have ample experience with veterans Dai Ebsworth and Raff Williams in the second row - and if they manage that and skipper Setaro again has the space to release his backline, they can get the job done.

Whitland: Jonathan Thomas, Liam Price, Scott Lloyd, Josh Thomas, Sean Coles, Nico Setaro (capt), Tom Parry, Aaron Mayne, Kevin Allen, Michael Ryan, Raff Williams, Dai Ebsworth, Ben Kirk, Ryan Morgan, Jack Mason. Replacements: TBC.

Fishguard v Pontyberem

It's shaping up to be another nervy finish for The Seagulls, who currently lie four points clear of the bottom two with a game in hand.

But despite losing 42-19 away from home, they will target visitors Pontyberem tomorrow.

Fishguard actually had joy from going wide in that game, scoring three tries, but I expect they will play to their traditional strengths at The Moors and the likes of Simon James, Chris Shousha, and skipper Gavin Walsh will play crucial roles in the ball carrying stakes.

What the home side cannot afford is ill-discipline, with The Bont having experienced No 10 and prolific points gatherer Mike Sauro in their ranks, and Walsh and co will also be wary of former Narberth flanker Wayne Williams at the breakdown.

But Pontyberem lie just seven points ahead of Fishguard having played three more games, and these are the kind of games that Huw Evans and Gareth Thomas' side have to target from here on in.

Mumbles v St Clears

Like Fishguard, every game is now critical for St Clears, and they can ill-afford to be rusty despite having not played since drawing 7-7 with Llanybydder in January.

But at least Mike Jones' side go to a Mumbles team that has suffered three straight defeats to Tumble, Pontarddulais, and the team just below St Clears, Amman United.

That last result did little to help the Carmarthenshire Saints, who lie just two points clear of both Amman and the relegation zone - and they will want local rivals Whitland to do them a favour in their already mentioned trip there tomorrow.

St Clears have won just once away from home this season after a superb scrummaging display inspired a comeback win over Carmarthen Athletic - and hooker and skipper Dafydd Walters and his pack must produce more of the same tomorrow if they are to come home with any points.

Division Three West A:

Haverfordwest v Neyland

These sides produced a great game in awful weather in November - eventually drawing 19-19 at The Athletic Club.

Both are teams that look to go wide with young and exciting runners out wide, so I would hope for more of the same tomorrow.

Centre Gareth Owen adds class to The Blues and he cut over in their 24-22 win over Cardigan last week, and it should be a good battle in midfield with George Williams scoring another eye catching try for The All Blacks in their 31-3 win over St Davids last time out.

Interestingly in the last meeting, it was Neyland pack that had tomorrow's hosts in all kinds of trouble at the scrum - but then it was Bruce Evans' side that were in control at the lineout.

So both packs will want to address certain things tomorrow, and clean ball will be crucial if respective outside halfs Liam Mainwaring and Steve Martin, both more than capable of also doing individual damage with ball in hand, want to go wide.

Laugharne v Pembroke

Undoubtedly the clash of the day in this league comes at Woolford Park.

Laugharne trail Pembroke by 14 points, but have two games in hand and a win here would suddenly put them right in the title picture.

Their last game was more than a month ago when they hammered Tregaron 58-0, while The Scarlets also go in on the back of a big win over the Mid Wales team, prevailing 81-12 last Saturday.

The battle of the back rows will be huge, with Laugharne's key performer and try scorer this season, Mike Williams, likely to pack down at No 8 against Sam Smith, who has been in destructive form for Pembroke.

But both teams have the backlines to threaten as well, with respective No 10's Owain Thomas (Laugharne) and Toby Smith (Pembroke) capable both happy to go wide with good runners outside them.

In that departmennt it was winger Simon Stanford who impressed for the Scarlets with a hat trick of tries last week, and the extra recent game time for Geraint Lewis' side may well give them the edge going into this. And if Pembroke do prevail, I cannot see them blowing the title from there.

But Laugharne captain Carl Smith and his side will know the importance of tomorrow and will be more than ready - and I expect an intense 80 minutes. 

Llangwm v Cardigan

The recent public plea for players from Llangwm suggests all is not well at Pill Parks, despite a string of improved performances of late.

It appears that for team manager Richard Scriven and coaches Robbie Neill and Colin Picton, the priority is now finishing the season unscathed and trying to rebuild in the summer.

So it remains to be seen what squad they have out tomorrow, byt they host a Cardigan team who have suffered last gasp defeats in their past two games against Aberaeron and Haverfordwest.

The latter defeat came on Saturday, but The Teifisiders showed enough to suggest they can finish the season strongly, with the centre pairing of Dafydd Watkins and Marcus Castle impressing in the absence of skipper Emyr Harries.

Tom Dunn is also proving an elusive runner at No 10, and I suspect The Wasps will look to keep this one tight up front and deny the visitors space out wide.

Pembroke Dock Quins v Aberaeron

The Quins have not played since February 17th, and their season has inevitably been disrupted since Christmas due to the annual 'shutdown' problems.

And you feel Ossie Boswell will need a full squad available tomorrow against a tough Aberaeron side, whose last game was on March 10th when a last gasp Rhodri Jenkins penalty saw them beat Aberaeron.

The Mid-Wales team are fifth, and while promotion is beyond them, they will want to push for a top three finish.

To have any chance tomorrow The Quins will have to match the away side's big and physical pack, and No 8 Stef Halwood and co will have to be at their best to have the edge up front.

If they can do that, and have a full compliment available, they have the backline to cause problems.

St Davids v Milford Haven

The task in front of Milford now is simple - they simply have to keep nothcing bonus point wins and hope that a fixture backlog for Pembroke proves their undoing.

Alan McClelland's men will be confident of a five point win here having beaten the Saints 77-5 in November, and like that meeting, in which Craig 'Yoda' Thomas had a hat trick of tries - they will look to play at pace and go wide every chance they get.

The Saints were showing improvements post-Christmas but were convincingly beaten at Neyland last time out, and will need to plug the gaps in midfield that The Mariners exploited ruthlessly at The Obs.

Regardless, captain Rhys Price will want an improved display from his side in their last home game of the season.
