Sudbury Snooker Club B won the derby with their D side 5-1 to leave them top of the Halstead and District Widdop Snooker League.
The match saw a welcome return to form of Gratham Cuthbert, who along with his teammate Sam Grant won both his matches.
The only blot on the B side’s performance was the defeat of their captain Colin Cole, who lost a closely-fought match to Frank Ervine of the D side, with the latter profiting from a fortunate blue dropping in.
The B side are three points ahead of Haverhill, who won the match against Sudbury Snooker Club C 5-1 thanks to John Driver and young Charlie Ripp winning both of their frames.
Thanks to an outrageous respotted black pot, which went up and down the table three times, by Colin Bayley against Andy Driver, the C side won their one and only frame.
Charlie Ripp, from Haverhill, looks a real prospect to go on to a higher standard.
In the other match, Sible Hedingham drew 3-3 at Earls Colne.
Joe Kane Jnr got Sible off to a winning start against Luke Heard before Paul French beat Steve Kane in controlled fashion.
Tony Newman beat George Williams and Heard lost to Steve Kane on the colours before Newman beat Joe Jnr Kane, and French lost to Williams.
