Cliftonville hammered Coleraine at Solitude to stretch their lead at top of the Premiership to 12 points.
Aaron Canning's own goal gave the Reds an early lead and Liam Boyce's cool finish made it 2-0 after 17 minutes.
The impressive Boyce set up the final three goals with Joe Gormley firing home five minutes before the break.
A low-key second half came to life in the last five minutes with Stephen Garrett slotting in before Eamonn Seydak completed the rout.
The artificial surface at Solitude meant this was the only league game to survive the weather, although a strong wind made playing conditions difficult.
Coleraine, who enjoyed the wind advantage in the first half, made a strong start and Cliftonville keeper Conor Devlin kept out Ruairi Harkin's free-kick before punching over from a cross.
But their good opening was undone after just three minutes when Canning turned Ryan Catney's low cross into his own net.
The Reds assumed control and Boyce netted his 26th goal of the campaign after Catney headed down from a Garrett cross.
Canning cleared off line to deny Gormley before the striker shot beyond keeper Michael Doherty to complete another slick move from the hosts.
The tempo dropped after the break and a disappointing Coleraine side never threatened a comeback.
Cliftonville finished the game with a flourish, first with Garrett latching on to a superb pass from Boyce before beating Doherty after 86 minutes.
Seydak hit the net from Boyce's cross three minutes later and Garrett struck the woodwork in injury time.
"A clean sheet, 5-0 at home - you can't ask for more than that," said Cliftonville manager Tommy Breslin.
"The scoreline maybe flatters us a bit but I'm delighted we got the points.
"We were good in the first half and a bit slow to get going in the second half, but we competed well and I'm happy with the result."
