Sheffield Tigers extended their lead and Sheffield moved up to fourth place as the two top sides in the city both recorded victories in National Three North.
Tigers were denied a four-try bonus but adapted better to the heavy conditions on a wet and miserable day to win 26-3 on their visit to Cheshire rivals Lymm.
The Dore Moor side eased in front with the first of three penalty goals from stand-off Mark Ireland and increased their lead with a try by winger James Montgomery. Ireland missed the conversion but added another penalty before Lymm replied late in the first half.
Ireland kicked Tigers further ahead with a penalty before converting a try by winger Pete Swatkins, and right at the end back row man Lee Monks sealed the win with a third touchdown.
Sheffield were on the attack from the start and ran out 38-3 winners over Wirral at Abbeydale Park.
They took the lead after just four minutes when No 8 Jonny France crashed over for the opening try, and there were others from flanker Alex Fawdry, winger Rupert Broadley and second row Dominic Parsons.
Full-back Joe Cribley landed four penalties as well as converting all three second-half tries.
Tigers now lead National Three North by eight points from Hull, who ousted Waterloo from second place, while Sheffield have moved ahead of both Wirral and Rossendale.
Dinnington slipped one place to fifth in North One East when they were beaten 29-5 on the long journey to Alnwick.
Alnwick opened up a 17-point lead before Dinnington replied just before half time with a try by No 8 Will Marshall, and the visitors had a player in the sin bin when they conceded their next try.
