NY Post She’s the new Met good-luck charm — with a sexy secret weapon.

When Jon Niese pitches tomorrow on Opening Day against the San Diego Padres, his gorgeous new wife, Leah, will be wearing Amazin’ blue panties — just as she has faithfully done at every game pitched by the lefty love-of-her-life.

“I’m the superstitious one,” said Leah, 23. “I have lucky underwear — they’re Mets underwear.”

Leah and Jon, 26, married in January in Ohio after dating for more than three years.

Boom there you have it.  The Pirates are your 2016 World Series Champions.

If you fired up some local sports talk radio you hear the same “needs” from callers.

“We need a top of the line ace.”

“We need a power hitting first baseman”

I’m here to tell you right now that those aren’t the needs that win championships.  We needed some big city sex appeal and locked that down today via Leah Niese.

What did the Kansas City Royals do to get over that 2014 hump and win the 2015 World Series. Kendrys Morales? Child please. Edinson Volquez? We know that wasn’t the key.  Oh then it is definitely Johnny Cueto right? Nope he’s stinky too.

The key to the Royals success in 2015 was sending their playboy Eric Hosmer out and locking down Kacie McDonnell.  Kacie brought KC (zing) big city sex appeal to a small market and was the final piece to a championship team.

And don’t you worry Bucco fans, The Yuppie Yinzer is on his A-Game today, getting Mrs. Niese some fresh new black and yellow panties.
