Clyde dented illness and injury-hit Partick Thistle's promotion challenge with a workmanlike victory.
Clyde's Eddie Malone and Thistle's Brown Ferguson both went close before Steve Masterton's 18-yard drive gave the home side Clyde a deserved lead.
The second came when Masterton's inswinging free kick gave Craig McKeown a simple header after the break.
Thistle's misery was complete on the stroke of full-time when Scott McCulloch was red-carded.
