La Boca celebrates as Julio Cesar Falcioni's men earned their first league title since 2008 with a convincing performance against the helpless visitors
Needing only one point from their last three games to win the title, the Xeneizes secured their 30th league crown in history with the result.
With star Juan Roman Riquelme on the bench having not featured in more than a month and a half with injury, the physical squad continued it's league domination, overpowering their opponents for most of the contest in their return to the league summit.
The festivities were enhanced early on when Boca opened their account just 10 minutes into the encounter. Dario Cvitanich fired home from close-range after a dangerous corner. The ball made contact with several players in the box, with Facundo Roncaglia heading onto the crossbar before the former Ajax striker saw his shot cleared off the line. The defender's second attempt was denied by Luchchetti at the near post, ultimately ending up at the feet of Cvitanich, who pounced on the rebound from metres out to finish into the left side of the net.
Boca continued to pressure with their potent attack in the moments that followed, with Cristian Chavez nearly putting his side up 2-0 with a long-range effort that flew over the goal.
Ricardo La Volpe's men showed next to nothing as they faced the slightest advantage, being forced to defend time and time again, but it was not enough. Cvitanich doubled the score moments before the half when off a free kick, a cross from the right aimed towards the middle of the box met the striker perfectly, where he volleyed his effort off a defender and into the right side of the goal, beating the outstretched custodian.
The comfortable advantage positioned Boca just 45 minutes away from the title, and in the second half it took the home side just one minute to make the stadium explode for a third time.
On the counter-attack, Cvitanich controlled a long ball deep in the attacking half and laying off to Diego Rivero, who from 30 metres out drilled home a spectacular effort, transforming the Banfield goalkeeper into nothing more than a spectator.
Boca continued to dominate in the second half, enjoying long spells off possession as they saw off the remaining minutes as fans chanted the league's top team, with Riquelme coming on with 30 minutes to go to take part in the celebration.
With the win Boca confirm the capture of the first title since 2008, sitting 11 points ahead of second-place Racing with two games to play.
Falcioni's men will travel to face Arsenal de Sarandi midweek in the penultimate fixture, while Banfield, who remain in the cellar of the league with 11 points, host Belgrano.
