Hamilton Accies thrashed 10-man Livingston to move above them and into fifth place in Division One.
Jon McShane gave the visitors an early lead, collecting Martin Canning's long ball before finishing coolly from six yards after just three minutes.
The home side were reduced to 10 men eight minutes later as Jason Talbot received a straight red for a late tackle on Alex Neil.
Just a minute later the Accies doubled their lead. Daniel Redmond was found in the area by Neil and clinically found the bottom corner of Andrew McNeil's goal.
Jon Routledge scored a spectacular third, firing home right-footed from 25 yards out.
Routledge grabbed his second nine minutes before the end, again letting fly from outside the area, this time using his left foot.
