There hasn’t been this much smoke and mirrors in New York since the velvet rope outside Studio 54 stretched for blocks.

Yesterday, under a perfect spring sky, the Yankees rode a pair of players rescued from the street in March to beat the free-falling Blue Jays, 3-2, in front of an announced crowd of 36,872 at Yankee Stadium.

Brennan Boesch and Lyle Overbay, who were released by the Tigers and Red Sox, respectively, during spring training, homered off ex-Met and last year’s NL Cy Young winner R.A. Dickey.

“We feel if we pitch we will get contributions from somebody,’’ starter Phil Hughes said after contributing six innings of two-run, seven-hit, nine-strikeout pitching to the fourth straight victory over the Blue Jays.

While the Yankees have relied on thick smoke and large mirrors offensively, their pitching has been very good and the bullpen exceptional.

“When they get to the [late innings] with [Mariano] Rivera and [David] Robertson, they are pretty good,’’ Blue Jays manager John Gibbons said of Robertson, who worked a perfect eighth, and Rivera, who notched his ninth save in nine attemptswith a clean ninth.

Across the past six games, of which the Yankees have won five, the relievers are 2-0 with four saves and feature an ERA of 1.00.

“That’s been our M.O. the last few years,’’ Hughes said. “If you give six or seven solid innings we have a chance to win.’’

Considering the late-game bullpen names are Joba Chamberlain, Robertson and Rivera, hold off on the smoke and mirrors angle.

Yet, that theory can’t be ignored on the other side of the deal. Teams don’t go 15-9 with Boesch, whom the Tigers cut despite being 28 and having an option remaining, hitting fifth, and Jayson Nix sixth.

“It’s a good clubhouse, that’s part of it,’’ said Overbay, whose third homer of the season was delivered with two outs and Travis Hafner on first in the seventh and erased a 2-1 Blue Jays lead.
