Brown has turned up the heat on Danny Lennon's League Cup winners all week as the Dark Blues look to cut the gap on the Buddies to just five points. Brown has worked wonders to keep the Taysiders in with a fighting chance of staying up as they prepare to host Aberdeen on Sunday while Saints face a tricky trip to Hearts on Saturday.
And Brown said: "It's crunch time. It's obviously going to be an important weekend for all concerned so we'll see how things pan out. We hope Hearts can do us a turn by beating St Mirren. If they can do that, then we'll look to do our bit on Sunday by getting a positive result against Aberdeen."
He added: "That has got to be the way we approach it,
"We're on a decent run of form and if there is any opportunity to cut the gap further then we have to try and seize the opportunity."
Brown has led his side to three straight wins in April in their point-blank refusal to concede relegation but the manage of the month insists it is all down to the players he inherited from previous boss Barry Smith back in February.
He added: "I take my hat off to them. They've been brilliant from the start.
"I never had half a mind that it would be over soon. Never would I think like that.
"I always felt as though we would claw it back; how much we would claw back is down to the players getting the results.
"Considering we only had three victories in 27 coming in then I thought we could only go one way, and it was about getting the team organised and working until the last whistle."
