A classy double from Adrian Mierzejewski led Sydney FC to a dominant 3-1 win in the derby against Western Sydney at Allianz Stadium.
The Sky Blues conceded early on when Oriol Riera tapped home, but Polish ace Mierzejewski had his side level before the interval with a superb free-kick.
He grabbed his second goal ten minutes into the second half, becoming the first player to score four goals in Sydney derbies.
And Graham Arnold's side made sure of the points with 15 minutes to go when Milos Ninkovic set up Bobo for his 21st goal of the season.
Sydney FC restored their 11-point cushion at the top of the table and will extend that to 14 if they beat second-placed Newcastle away next weekend.
Wanderers struck an early blow when Redmayne palmed away a cross to Riera who netted from close range.
The hosts had gone close when Wanderers keeper Vedran Janjetovic needed to tip around a shot from Mierzejewski.
The equaliser came when Ninkovic was brought down just outside the area, with Mierzejewski firing his free-kick in off the underside of the bar.
The Polish midfielder smashed home a first-time volley to give the home side the lead, after Matt Simon laid the ball off to him following Ninkovic's half-cleared cross.
Ninkovic was involved again in the third, going on a mazy run before defly back-heeling the ball to Bobo who fired past Janjetovic.
That secured their 16th win in 21 games this season, though they almost conceded for a second time late on when Jaushua Sotirio's shot was saved at point-blank range by Redmayne.
Western Sydney are 12121/1 to win the Grand Final.
Wanderers are 5/6 to win their next game against Perth, who are 3/1 with the draw 3/1.
