A late James Chambers penalty was enough to give Hamilton victory over Partick in the Ramsdens Cup.
Hamilton's Derek Lyle got on the end of a William McLaren centre after 32 minutes, but Thistle goalkeeper Scott Fox punched to safety.
The Partick goal was leading a charmed life when Simon Mensing connected with a McLaren cross to strike the woodwork.
The goal came four minutes from time, Jonny Lindsay fouling Douglas Imrie, and Chambers made no mistake.
