It all comes down to 80 minutes of rugby for Castlebar on Sunday as they strive to gain promotion back to the top level of junior rugby in the province.
After finishing their regulation league season in Junior 1B, Castlebar finished in second place in the table on seven points behind league winners Creggs, but they have booked themselves a spot in a promotion relegation play-off against Galwegians on Sunday in Headford at 2.30pm.
Castlebar won nine of their 14 league games, drew one, and lost four during the league - while their opponents who finished second bottom of the top table only picked up two wins all season.
The Cloondeash side finished off their regulation league season last weekend with a 22-16 win on the road against fellow Mayo outfit Ballinrobe, with Sean Tonra crossing the whitewash three times in the game and Liam Molloy also touching down.
Castlebar will be hoping that Molloy and Tonra will keep up their scoring run, while the likes of David Staunton, Daire Mulgrew, and Sam Bolger will be able to keep up their scoring form.
Ballina followed up their Connacht Junior Cup win a fortnight ago by being presented with the league title trophy following a 45-7 win over Castlebar's opponents last weekend. Ballina ran in seven tries in that one to once again showcase their dominance in the game on a local level this season, going through the whole league season without dropping a single point. This weekend sees the north Mayo men take on Bandon on Saturday in an All Ireland league qualifier.
