For once, you really can “Blame It On The Rain.” Much like that once misplaced Milli Vanilli hit some 20 years ago, that accurately reflects both New York baseball teams on the 16th day of May with the Subway Series on tap.

So much for good May weather. But hey. Do either the Yankees or Mets deserve the sun to shine down on them at this early juncture of the season? We already know the answer. Maybe it’s a bit of poetic justice that the weather is so crappy reminding us more of late March and April rather than traditional May days.

Both teams stink. Sure. It’s still very early. There’s plenty of time for the Yanks and Mets to turn it around. Sometimes, that’s forgotten in such a demanding town which is all about the present when it comes to its two baseball teams. The grind of a 162-game schedule has peaks and valleys. Unfortunately, both clubs with high expectations have hit a lull entering this weekend’s three-game set at Yankee Stadium a combined 40-41. Remarkably, it’s the first time since the Subway Series inception that the two metro area teams entered under .500. But as esteemed New York Post columnist Mike Vaccaro pointed out in a well written column, it was bound to happen sometime.

Symbolism is a funny thing. Almost to a U2 hit, “Mysterious Ways.” That it’s pouring literally and dark as can be for this time of year epitomizes the slow starts by our two ballclubs who so many fans in this area live and die with.

Just listening to all the panic on WFAN airwaves is enough to drive you insane. Of course, the “Fire Willie” demands have only intensified after his team’s dreadful 3-4 homestand against last place fodder. Granted. The manager isn’t doing the job. Ultimately, it comes down to his players who are plenty talented but have been lacking consistency, intensity and common sense. Why is it always the same two players who show frustration over their team’s lackadaisical play?

On the flip side of town, the Yanks just lost three of four to the improved Rays down in Tampa drawing the ire of Hank Steinbrenner. They have their own issues which include a paltry offense that’s putting more pressure on the pitching staff. The good news is Mike Mussina has suddenly rediscovered himself and Darrell Rasner, who will oppose Johan Santana whenever Game One gets underway has pitched well. The alarming is the continued ups and downs of Andy Pettite, Ian Kennedy’s struggles and LaTroy Hawkins’ implosions. Combine that with a popgun offense and it’s hard to win games.

Maybe A-Rod’s quad will finally be healthy enough to return soon and help inject much needed righty power in a dead lineup. Who knows what the time table is for Jorge Posada? For now, Joe Girardi continues to pencil in the Shelly Duncans and Morgan Ensbergs while batting Melky Cabrera sixth.

Is this the weekend Jose Reyes sparks the Mets to a big series win before headed to Atlanta possibly saving the manager’s job? Or does the Yankee captain step to the forefront leading his slumping team to two of three and perhaps back on track?

Hard to say. What I do know is that rain never felt more appropriate. And we don’t mean the cold November Guns N’ Roses kind. Bet those two teams wish it were.

We got a long way to go.
