Waters I took a firm grip on top spot in Division One of the Hemel Hempstead Table Tennis league as they came out on top in a closely-fought contest against title rivals Adeyfield I.
Waters edged the contest 6-4, before being awarded a 10-0 victory over Tring.
Adeyfield, however, bounced back to form with a 10-0 win against Flamstead I as Mark York, Mike Boardman and Nigel Finn all helped themselves to maximums.
Elsewhere, Waters A beat Row 7-3, with Ken Stonebridge taking a hat-trick for the victors.
The side followed this up with a 5-5 draw with Adeyfield A, with again Stonebridge again bagging a maximum.
Adeyfield then suffered an 8-2 defeat to Flamstead I – for whom Angela Smith secured a treble – while Tring lifted themselves off the bottom of the table by beating Waters B as Mark Luscombe took a maximum.
Meanwhile, in Division Two, leaders Flamstead A picked up two crushing wins. Northchurch I were dispatched 9-1, before club-mates Flamstead B took an 8-2 beating. John Stock and Jack Reyland took two maximums apiece.
Second-placed McAlpines also picked up points as Trevor Laverno kept his 100 per cent record in tact, while KLCC I won 7-3 against Adeyfield B with Mark Yelland taking a maximum.
Despite a second maximum from Yelland, however, KLCC were beaten 6-4 by Waters C in their next outing.
In Division Three, unbeaten table-toppers Highfield increased their lead by winning 9-1 against Waters D, with Alan Jolly and Mark Chiles both securing maximums.

Flamstead C took full advantage of that result by leap-frogging both teams thanks to a 9-1 win over Northchurch A and a 7-3 triumph over Waters D.
Roy Lambden and Tony Bourke took maximums in the first match, with Phil Oswin doing likewise in the second contest.
