Santos are currently 10th in the league with 38 points from 29 matches played. Muricy Ramalho's side are on a bit of a decent run at present; one defeat in seven, with three wins and three draws.
The highly touted Neymar will be missing this evening as he is on international duty, however he was also absent for the away victory at Botofogo last week.
As far as the goals go, Santos' matches average 2.48 this season and eight of their last 12 at home have gone over 2.5. It's also worth noting that they've kept just three clean sheets in their last 13 at Estádio Urbano Caldeira.
Last year's runners up, Vasco da Gama are In fourth place at present and while they are six points adrift of third, they only have a one point cushion from Sao Paulo in fifth, so they can't afford to slip up.
Marcelo Oliveira's men ended a six game winless run on the road against Atletico GO last time out so they should have a bit of confidence restored.
While they aren't as prolific as Santos, three of their last eight have gone over 3.5 goals, so they are capable of producing high-scoring affairs.
The goals aren't guaranteed to flow here but taking on under 2.5 at around the [1.81] mark is certainly value and that's why I'm making it my lay of the day.
Lay Under 2.5 goals in Santos v Vasco da Gama @ [1.81]
