• William Gros strikes in Kilmarnock win over Motherwell
• Aberdeen's poor home form sees St Mirren hold on to a point
Dundee United's improved form under their new manager Jackie McNamara continued as they saw off 10-man Hearts 3-1 at Tannadice to earn back‑to‑back victories.
The Tangerines got off to a good start with Johnny Russell swivelling and finishing with his right foot low into Jamie MacDonald's right-hand corner from eight yards in the second minute. Hearts had Ryan Stevenson sent off for what appeared to be a high challenge on Gary Mackay-Steven midway through the first half.
Willo Flood made it 2-0 for United on 62 minutes only for Michael Ngoo to pull back a goal for Hearts in the 76th minute when United failed to clear Fraser Mullen's corner and Ngoo pounced to drive home from 12 yards. Despite Hearts' best efforts to force a late equaliser it was the hosts who ran out victors, with the substitute Michael Gardyne who sealed the result from point-blank range a minute from time.
An early own goal and a late header from William Gros gave Kilmarnock a 2-0 home win over Motherwell. Following a pretty even start Killie took the lead after 12 minutes. Ross Barbour drilled a low ball into the box only for Stevie Hammell's outstretched leg to deflect the ball past his own goalkeeper from 10 yards.
Motherwell took the game to Kilmarnock and Gros was responsible for three goalline clearances as the visitors bombarded Kyle Letheren's goal. Kenny Shiels's side held on and increased their margin after 71 minutes. James Dayton put in an inviting cross from the left touchline and Gros, from six yards, powered a terrific header down and past Darren Randolph.
Motherwell's frustrations boiled over in the closing stages when the substitute Fraser Kerr and the captain Keith Lasley were sent off within minutes of each other for reckless tackles on Dayton.
Aberdeen survived the dismissal of Mark Reynolds for two bookable offences to earn a point in a goalless home draw with St Mirren. Jamie Langfield proved to be Aberdeen's hero for the fine save he made from the in-form striker Esmaël Gonçalves in the dying stages, with the game teetering towards the visitors. Aberdeen have won only three out of 13 home games.
Rangers cruised to a 4-0 victory over their nearest neighbours Queen's Park that took them 22 points clear at the top of the Third Division. Andy Little scored twice, with Ian Black and Dean Shiels also on the scoresheet, as the Light Blues returned to winning ways.
