Rangers FC and Celtic FC both won on Wednesday night to leave the Ibrox side three points clear at the top.
Captain Barry Ferguson inspired Rangers FC to a hard-fought win at Hibernian FC which kept them three points clear of main title rivals Celtic FC, who beat Dundee United FC.
Hibernian slip to sxth
Ferguson struck his 16th goal of the season in the 57th minute and the 2-0 win was sealed late on by Claudio Caniggia with a simple tap-in. Gary Smith's 89th-minute red card for the Easter Road side completed a frustrating night for Bobby Williamson's outfit who slip down into sixth place.
Celtic's 2-0 win at home to Dundee United came courtesy of first-half goals from John Hartson and Henrik Larsson - whose strike was his 33rd goal of a prolific season. Elsewhere on Wednesday, there was drama at Rugby Park as Kilmarnock FC overcame Motherwell FC 1-0 in a reversal of Saturday's Scottish Cup result. Motherwell goalkeeper Francois Dubourdeau was sent off for a foul on Craig Dargo and Kris Boyd scored from the 80th-minute penalty to take his team above Hibs in the table.
Fine start for Amor
Livingston FC's high-profile signing Guillermo Amor enjoyed a fine start to his career in Scotland on Tuesday night. The former FC Barcelona man helped his team to a 3-1 win against Partick Thistle FC. Marvyn Andrews headed the visitors into the lead before Alex Burns scored his 13th goal of the season to draw the sides level. However, two goals in the final 20 minutes killed off Thistle. First Rolando Zarate struck and then Colin McMenamin registered his first goal for Livingston to clinch the win and give Amor a dream start.
Aberdeen FC's miserable run in front of goal continued at Pittodrie as a last-minute Gary Wales goal gave Heart of Midlothian FC a precious 1-0 win which aids their bid to qualify for next season's UEFA Cup. Hearts remain in third place, while Aberdeen's hunt for a striker before the transfer window closes on Friday will now intensify.
Hearts' European bid recieved a boost by Dunfermline Athletic FC's home defeat by Dundee FC. Barry Nicholson put through his own goal to give Jim Duffy's men a 1-0 victory which takes them into seventh position.
