Leaders Hamilton extended their unbeaten run to five games with a 1-0 victory at Queen of the South.
The only goal of the match came on 16 minutes when Mickael Antoine-Curier controlled Tony Andreu's cut-back before finishing past Zander Clark for his third goal of the season.
Hamilton goalkeeper Kevin Cuthbert denied the home side an equaliser just after the hour mark with a superb save from a Derek Lyle header. The striker then saw another header cleared off the line by Stephen Hendrie moments later.
Eamonn Brophy almost gave Hamilton a two-goal cushion minutes after replacing Antoine-Curier but his miss did not prove crucial as Hamilton went home with all three points and gained revenge for last weekend's cup defeat.
