Johann Berg Gudmundsson was on target again with a classy finish as the Clarets proved too strong for their Scottish visitors.
Gudmundsson struck the Clarets’ fourth goal and his second in three warm-up games as he continues to get back up to full speed following last season’s injury-hit campaign.
And an impressive showing from the Icelander was just one of a number of pleasing points in a slick performance from another line-up showing a mix of youth and experience.
Jay Rodriguez opened the scoring from the penalty spot before teenagers Max Thompson and Lewis Richardson both found the net to help Burnley lead 3-1 at the break.
