Sheffield Tigers held fifth place in National Three North when they scored five tries to three in a 29-21 win at Yorkshire rivals Huddersfield YMCA on Saturday.
Winger Henri Packard scored the opening try, and there was another for full-back Peter Swatkins, his 51st league try for the club.
Tigers went 17-0 up, but Huddersfield fought their way back into the game and it was a close call until the last ten minutes.
Sheffield extended their lead in North One East with a seven-try romp against Driffield at Abbeydale Park on a day which also saw bonus-winning victories for Dinnington.
Sheffield ran out 42-0 winners over Driffield to edge further ahead of second placed Percy Park who, although winning, were restricted to two tries.
Even with two players off the pitch, Sheffield still dominated and a Ben Parker penalty, along with two Johnny France tries gave them a 13-0 lead after 16 minutes.
Tom Womack, Rupert Broadley and Gareth Morley helped to build the score and Joe McHale put in an impressive performance, crashing over to score a try in each half.
Dinnington rattled off 20 points without reply in the first half and eventually finished 53-12 ahead in their North One East match at bottom placed Horden.
Winger Steve Thompson and flanker Mike Leitch both touched down twice in Dinnington’s eight-try haul, and there were others from winger Mylan Miller, fly-half Jonny West, No 8 Jalan Farras and prop John Marshall.
West landed a penalty and a conversion, but Chris Williams converted four more.
Barnsley, after twice taking the lead, were edged out 26-25 on their visit to current top side Bradford Salem in Yorkshire Two.
A four-try win could have put former leaders Barnsley back level on league points with Salem, but in the end they were left to salvage a losing bonus. Barnsley opened midway through the first half with a penalty by Andy Appleyard and, after Salem had taken the lead with a converted try, Barnsley edged back in front 8-7 when winger Will Smith raced over. A try by Ashley Salkeld, on the other wing, converted by Appleyard, who also slotted over a penalty, put the visitors further ahead.
But Salem turned the game on its ahead with three further tries before Barnsley stormed back with a try by centre Thomas Swann, converted by Appleyard.
