An on-point Sydney FC have effectively won their first piece of silverware in seven A-league seasons, dismantling Melbourne Victory 1-0 to all but mathematically claim the Premiers' Plate.
Bobo buried his 11th goal of the campaign to seal Friday's defining Big Blue, lifting the Sky Blues 11 points clear of second-placed Victory and rendering a comeback for Kevin Muscat's men nigh on impossible.
Graham Arnold's tearaway leaders need just four more points from the five remaining rounds to lift the trophy.
It was the Brazilian striker's name emblazoned the scoreboard 50 minutes in, but the goal really belonged to his whole team and was orchestrated by none other than playmaker Milos Ninkovic.
The Johnny Warren Medal frontrunner played the ball inside for his teammates to emulate a warm-up drill to perfection, as Josh Brillante shifted to Alex Brosque and then Filip Holosko, who atoned for an earlier miss with a pin-point cross, which Bobo tapped home.
The Allianz Stadium pitch was a swamp under heavy rain but both teams cut through the quagmire with incongruous ease and fashioned chances aplenty for the 13,310 who braved the wet.
Sydney were always the more likely, and were lucky Michael Zullo was only shown a yellow card early for bringing Marco Rojas down as the winger closed in on goal.
Holosko failed to make goal-mouth contact with a Bobo ball and Rhyan Grant had an audacious crack from distance, while Brosque rifled a left-foot strike over the bar before the skipper was superbly denied by Lawrence Thomas.
Up the other end, former Melbourne Victory goalkeeper Danny Vukovic pulled off a cracking clutch save to stop Jai Ingham from point blank range as Rojas repeatedly carved through Sydney's defence.
The Kiwi international caused the hosts issues and he soon put Ingham through again, only to watch the 23-year-old lump a lame header straight into Vukovic's arms.
After the break and one goal down, Victory pressed on.
But if they were going to equalise, the moment came and went just before the hour mark, when Besart Berisha inexplicably skied a gilt-edged chance from inside the area.
Moments later Ninkovic nearly doubled the lead in sensational style with a 30m volley that dipped slightly too late and kissed the roof of the net.
