Clinical Boca
With no other option, Boca set about pressing from the opening whistle.
And found a nervous Vasco side.
The team's leading assist provider this season, Blanco delivered a corner, and Di Lollo beat Sosa in the air to score (4').
A "dream scenario" for the visitors.
Vasco almost responded in the seventh minute following a counterattack.
But Adson and Bruno Duarte got their wires crossed.
A sign of a team rushing things on the pitch.
There was no shortage of intensity from either side.
Vasco tried to take control but continued to struggle without the ball.
And Saldívia's mistake allowed Boca to launch an attack that ended with Merentiel celebrating (34').
As things stand, Vasco need one goal to force a penalty shootout.
A draw would secure the Rio side a place in the final against Montevideo City Torque.
