Livingston cut the gap on William Hill Championship leaders Falkirk to six points with a 2-1 win at Morton.
Falkirk had seen their title celebrations delayed following a 1-1 draw at Ayr on Friday night – and Livingston made sure the champagne was left on ice for another week at least.
Cristian Montano and Scott Pitman had put the visitors in control, but Ali Crawford’s free-kick reduced the deficit just before half-time.
Play-off hopefuls Partick Thistle slipped to a 2-1 home defeat by relegation-battlers Hamilton.
Nikolay Todorov and Scott Robinson struck in the space of two minutes just after the quarter-hour mark.
Brian Graham headed a consolation in stoppage time as Thistle suffered a second straight league defeat.
Raith, though, missed the chance to close up on the top four after being held to a 1-1 draw at bottom club Airdrie.
Chris Mochrie had put the hosts in front after 19 minutes, but Raith equalised just before half-time through Jamie Gullan’s header.
Dunfermline also boosted their survival hopes with a 1-0 win at fellow strugglers Queen’s Park after Christopher Kane’s struck with 20 minutes left.
