Birmingham Moseley were the victims this time as Roth triumphed 33-7 at Clifton Lane.
The hosts set the platform with a dominant first-half display which saw them lead 26-0, Travis Gordon, Harry Newborn, James Norman and Luke Cole dotting down.
The league’s leading point-scorer, Lloyd Hayes, added three conversions.
Mose got on the board as skipper Ollie Stedman rumbled over, Tommy Taylor with the extras, but Titans sealed the deal with a penalty try.
Blackheath set-up three-way title chase
Things got better for Rotherham when Blackheath snapped Plymouth Albion’s 11-match winning streak 34-26 at The Brickfields.
A stunning opening from Club helped them move 19-0 up thanks to tries from Billy Harding, Tom Hughes and Jordan Burns, Sam Morley with a couple of conversions.
Plymouth replied as Iwan Jenkins added to Harry Wilkinson’s try, only for Archie Holland to cross for Blackheath.
Jenkins landed again after Huw Taylor powered over just before the break, Albion trailing 24-14.
Harding’s second – incredibly taking his seasonal tally to 39 in 21 matches – was added to by Morley to give Club breathing space.
But Plymouth hit back as Jack Oulton and Bobby Wigginton crossed, Jenkins converting the former.
Morley, however, had the final word with a 77th-minute penalty which denied the hosts a losing bonus.
The top-of-the-table with five games to play now sees Rotherham on 91 points, Plymouth 86 and Blackheath 82.
The latter host Roth on March 14 before the Yorkshiremen welcome Plymouth north seven days later.
Sale keep hopes alive but Park slip at Tykes
Sale FC may yet have something to say in the promotion race after they thumped visitors Dings Crusaders 47-12.
The Dogs now sit on 76 points.
And they blasted out the gate with Joe Green converting tries from Tom Walsh and Toby Wilson in the opening quarter.
The scrum-half repeated the trick after Corbin Thunder dotted down before the break, Dings on the board early in the second half as Raff Weston added to a Tomas Gwilliam try.
A Fergus Mulchrone effort sealed the bonus-point before Wilson’s second and the boot of Green made it 33-7.
James Robins took over kicking duties for Sale as Dan Birchall and Matt Bradley crossed the whitewash, Dings gaining a late consolation through Joe Jenkins.
Rosslyn Park’s top-three hopes suffered a major setback as they lost 45-38 at an inspired Leeds Tykes.
Charlie Walker’s second-minute try put the visitors in front before debutant Matt Salisbury bagged a brace for Tykes, Ed Crossland converting both and slotting a penalty for 17-5.
Bill Johnston added to a Tom Bell score for Park before Crossland landed another three-pointer.
The gap was cut to 20-19 after Johnston landed following Cameron King’s try, only for Seramaia Turagabeci Bai and Bertie Bradshaw to hit back for Leeds.
Crossland added to the second, but a Joe Luca Smith score made it 32-24 at the end of an incredible first half.
Bradshaw doubled up with another converted try to push Tykes further clear before Walker and Johnston reduced the arrears, Crossland replying with a penalty for 42-31.
The Londoners gave themselves late hope as Gareth Blackmore touched down, Johnston on target, before Crossland had the final word.
Leeds’ fourth win on the spin keeps them in ninth and now seven points clear of the relegation play-off place.
Tigers and Dings remain in relegation scrap
Only three points now separate 10th-placed Sedgley Park and second-bottom Dings Crusaders.
The former missed a chance to give themselves breathing space after going down 31-28 at home to Tonbridge Juddians.
The visitors marched 19-0 up as Lewis Gjaltema, Connor Lloyd and Tom Kendrick touched down, Lloyd with two conversions.
Tigers got off the mark as Ollie Glasse added to a Josh Ree effort.
Kendrick’s second secured TJs’ bonus, but Sedgley remained in the hunt as Glasse was on target following a Danny Rylance try.
A Rhys Henderson seven-pointer made it 24-21, only for Kendrick to complete his treble three minutes from time.
Lloyd gave the Kent men a buffer, and Rylance’s second converted effort was only enough to snatch a brace of bonus-points for Sedge.
Clifton boost survival bid after incredible Lions tussle
Clifton gave their survival hopes a massive boost while equally all but consigning Leicester Lions to the drop with a helter-skelter 54-40 home triumph.
James McKinney converted an early Ollie Stirling try to put the Bristolians ahead, Lions levelling through James Stubbs and Luke Bouchier.
Clifton moved 21-7 up through Jay Evans, Stirling and the boot of McKinney, before Leicester cut the gap with Bouchier adding to his own try.
But McKinney’s magnificent day from the tee saw the fly-half make it six from six after Harry Johnson, Zak Hamid and Tom Anderson crossed the whitewash.
A 42-14 half-time lead was extended when Hamid dotted down before Lions started a fightback.
Will Roberts and Lui Natui ensured a try bonus for Lions, a Bouchier kick reducing the deficit to 47-26.
Replacement Tom Quinlan was on target after Johnson doubled up, but Leicester fought to the death.
However, Theo Mannion converting tries from Jake Metcalfe and Aaron Dawson were ultimately too little, too late.
Rams lost a second straight game 36-31 at home to Bishop’s Stortford.
