Goals from Kenny McLean and Sam Parkin gave St Mirren a 2-0 victory over Scottish Premier League new boys Dundee at Dens Park.
McLean's 35-yard pile driver six minutes from the interval was fit on its own to win any game.
However, Parkin clinched the points in the 62nd minute when he controlled a Dougie Imrie cross before guiding the ball past Dees' veteran keeper Rab Douglas.
Dundee had their moments with midfielder Ryan Conroy hitting the post just before the break and Mark Stewart and John Baird missing great chances but it looks like being a difficult season for Barry Smith's team.
Bob McHugh earned Motherwell an unlikely point with a 1-1 draw against St Johnstone after Stevie Hammell had been sent off for the home side.
Murray Davidson headed Saints ahead in the 58th minute, moments after Darren Randolph had saved Dave Mackay's penalty when Hammell was penalised for Chris Millar going down.
Saints looked like securing the win against a home side looking tired from their Champions League trip to Athens and with three young substitutes on the park.
But one of those, McHugh, levelled in the 78th minute and referee Iain Brines soon evened up the teams when Rowan Vine was sent off on his first start for a second bookable foul on Shaun Hutchinson.
Motherwell pushed for a winner and only some excellent stops from goalkeeper Alan Mannues and some desperate defending prevented them getting one.
Ross County continued their long unbeaten run with a 0-0 draw against Aberdeen at Pittodrie.
The Dons enjoyed the better of the chances with Gavin Rae guilty of heading wide in the best opening, but the Staggies defended resolutely to make it 36 league games without defeat.
Manuel Pascali was the hero for Kilmarnock as they drew 1-1 against 10-man Inverness.
The Italian midfielder cleared off the line and netted the leveller moments before half-time to cancel out the opener from Caley Thistle's Andrew Shinnie.
The game ended on a sour note for the hosts with Owain Tudur Jones sent off for violent conduct after 79 minutes, putting a downers on a solid performance which included a penalty save from goalkeeper Ryan Esson.
