CARTHA are neck and neck for the top spot in the table with newly promoted Marr.
While the Ayrshire squad are ahead on points difference, the Dumbreck side remain undefeated after three games.
On Saturday, Cartha defeated a seasoned Hamilton side 28-19 and this week they face a tough trip to Ardrossan, currently breathing down their necks in third place.
Coach Gary Grant told ExtraSport: “We have only conceded one try in three matches, the boys are really playing well together.
“Ardrossan is a hard place to get points, the conditions are always difficult and they are a well drilled team, but there is no reason why they can’t win.”
Gary Grant’s side finished second last year, after being pipped at the post for promotion to the national league by neighbours GHA.
But this year, the Cartha coach thinks his side have what it takes to go one better.
He added: “We still have some new players to come in but our new additions are doing a great job.
“Ross Aitken has made a big difference in the backline while Fraser Paul and Matthew Archer have stabilised the scrum and given us a good platform to work from.
“It’s about staying injury free but if not, I don’t see why we can’t win the league this year. The guys are training well — there were 74 there last Thursday night and we had a huge crowd on Saturday.
“There’s a real buzz about the club.”
GHA are looking to stop the rot when they travel to face Biggar at Hartree Mill on Saturday.
Neither side has been able to record a win in this season’s National league and both will be hoping to improve after suffering disappointing defeats.
The southsiders will hope to bounce back after suffering a 45-10 defeat against Selkirk at Braidholm last Saturday.
Also on Saturday, Biggar suffered a 74-5 thrashing at the hands of league leaders Watsonians.
GHA head coach Gordon MacPherson feels if they can get their first win on the board the team can kick on for the rest of the season.
He said: “Getting the first win is what we need right now. You can build on getting your first win.
“A win is great for confidence, it lifts the whole club and that is exactly what we need.
“It won’t just happen we have to work hard, we have to make it happen and it means we have to really concentrate on training and everything we do.”
Whitecraigs defeated Dalziel 33-15 during their visit to Motherwell thanks in part to a hat-trick from new recruit Louis Senter.
This week Craigs face newly promoted, yet undefeated juggernaut Marr.
West of Scotland, Ardrossan and Falkirk have already fallen to the Ayrshire side this season.
