Past 5 Championship Meetings
2016 Wexford 1-21 Offaly 1-13 (All-Ireland qualifiers)
2012 Offaly 2-12 Wexford 1-13 (Leinster quarter-final)
2009 Wexford 2-17 Offaly 0-16 (Leinster quarter-final)
2006 Wexford 0-9 Offaly 0-8 (Leinster semi-final)
2004 Wexford 2-12 Offaly 1-11 (Leinster final)
There is no doubt that Kevin Martin's appointment as Offaly manager has given the county back some self belief and while they have no points on the board so far, the Faithful were far from disgraced in going down to Galway and Kilkenny.
They now welcome Wexford to Tullamore and it's a match they probably feel they can something out of. If defeat is to be their lot, Offaly will hope that the margin is narrow and such a margin will no doubt be crucial when various outcomes are decided come the second weekend in June.
Of course the bottom team in Leinster drops down to the Joe McDonogh Cup for next year.
Brian Cody recently expressed his dissatisfaction that this is the case, as against a lifeline that is thrown to the side who finishes bottom in Munster. Another Kilkenny man Eddie Brennan had his say this week, saying that relegation for whoever would be a sin and a shame.
Wexford got their campaign up and running with a hard-fought win over Dublin. Rory O'Connor emerged as the hero of the day with a couple of priceless points in added-time as Davy Fitzgerald's men prevailed by just two points.
Now, I did say it was a hard-fought victory, but many Wexford fans at the ground felt their side were always in control and should never have allowed Pat Gilroy's troops find a way back into the game. At one point, the hosts were 0-16 to 1-08 clear after 50 minutes at Wexford Park.
One man who also felt that his side should have put things to bed long before the 70 minutes was Davy Fitzgerald.
He told RTÉ Sport afterwards: "We shouldn't have been in that position. We should have had the game out of sight with ten minutes to go.
"We caused the problems ourselves and we nearly paid the price but fair play to the guys, they dug it out at the end. That was good. Under pressure, we got the result."
Wexford must get to the next level
Surviving in this Leinster section after a league where they ran Kilkenny close in the quarter-final would represent a good 2018 for Offaly.
For Wexford, however, the requirement to build and improve on last year is paramount. They ended 2017 with a loss to Waterford at the All-Ireland quarter-final stage, there were no complaints at the end, the gameplan employed wasn't flexible enough to break down the Déise resistance.
Davy's boys must now throw caution to the wind, while also upping their conversion rate if they are to trouble the likes Galway and Kilkenny. They way they rescued themselves on Sunday last is a plus and will no doubt eradicate any form of complacency as they head to the midlands.
Looing ahead: Davy Fitz told RTÉ Sport: "We know what it's going to be in Tullamore. It's going to be some battle. Any time Wexford and Offaly meet, it'll be down to the wire.
"We just have to go up there and give it everything we have.
"It's going to be an interesting 21 days. I like the concept (of the round-robin format)... but to play four in a row is going to be a big ask for us. If they're all like today, I don't know if it'll be good for the health.
"I'll sleep tonight anyway, that's for sure."
Optimism aplenty from our analyst as he feels his native county will give their all ahead of a crunch clash with Dublin on 3 June.
In the afternoon and evening, showers or longer spells of rain will move into the Southeast and South turning heavy and possibly thundery and some spot flooding is possible. Highest temperatures will range 17 to 23 degrees Celsius. For more go to met.ie.
