Yet Uddingston took the lead at Bothwell Castle Policies on Saturday with a Cammy Quinn penalty, before Cumnock hit back with two converted tries.
A Crichton try converted by Quinn brought the Villagers’ deficit back to 14-10 before the visitors landed a converted score to lead 21-10 at half-time.
The second half was all Cumnock as they secured their champion status with a further six converted tries. The Villagers snatched one back through Brown but Cumnock are promoted to West Division 1 as champions.
This Saturday, the Villagers’ battle to avoid relegation sees them travel to Wigtownshire, while Dalziel host Strathaven also in West 2.
