Henderson’s battling side slipped to their third defeat of the season to the Shannonsiders at the Markets Field on Saturday.
Lee J. Lynch, who scooped the man-of-the-match award, and Chris Mulhall were on target at the Garryowen venue as Limerick recorded a 16th win from 17 starts.
Martin Russell’s side are now 19 points clear and look unbackable favourites to bounce straight back up automatically after being relegated via the play-offs from the Premier Division last term.
“We gave up talking about Limerick weeks ago (in relation to the Shannonsiders winning the title). Everyone in this Division is playing for second spot at this stage,” said Henderson.
Lynch netted the opener after half an hour. The stand-in captain nutmegged one defender and skipped past another before driving a low, 20-yard drive beyond Paul Hunt. Minutes later Mulhall doubled the home side’s advantage with a powerful header from a cross from Shaun Kelly, who was making his 100th appearance for Limerick.
But Ramblers piled on the pressure after the break. Shane O’Connor broke into the box after 70 minutes but his cross was snuffed out by some last ditch defending while Freddy Hall had to claw a free-kick from Marcus Gustavasson from under his bar.
