Penallta will be hoping to bounce back from their first home defeat in almost two years when they head to Treorchy in Swalec Division One East this weekend.
They were beaten 23-22 by Heol y Cyw thanks to a last minute drop goal from Harley Thompson that allowed the visitors to steal the spoils after an epic battle. Mike Huckridge chipped in with five penalties and scrum half Matt Pound grabbed a vital try.
The home side had 17 points from the boot of Gary Wilkes to keep them in contention and they also earned a penalty try. It was Penallta's first league defeat of the season and the blow was eased by the fact second placed Rumney also lost their unbeaten tag.
