Ross County's relegation worries were deepened as they were well beaten by a slick Hamilton side.
The Accies started the better with James Gibson rattling the crossbar after just four minutes.
Good work from Mark Gilhaney, Davey Winters and James McArthur put in Marvin Winters who slotted home.
Hamilton were dominant and Gilhaney and Winters wasted chances to extend the lead as the home side cruised to a comfortable win.
