Hugh Murray was completely missing from the squad whilst Charlie Adam dropped to the bench. Billy Mehmet and Mark Reilly both started.
The first half was goaless but Clyde took the lead after fifteen minutes of the second. Former Morton man Alex Williams tapped home a corner and then proceeded to go wild in front of the Saints support, with Clyde boss Graham Roberts also running on the pitch to celebrate.
Adam replaced Simon Lappin nearely ten minutes later and had an immediate impact. He raced on to a through ball, apparently controlled it with his hand, and dispatched it past Paul Jarvie for the equaliser. Get this man signed up until the end of the season now!
It was Saints first shot on target all game, and the second one came ten minutes later when John Sutton tapped home Mark Corcoran's cross to seal an incredible and jammy victory.
Get it right up ye Williams!
