October has been one doubleheader after another for World Series-bound Rays pitcher Steven Matz and his on-tour Christian pop star wife, Taylor Cain Matz. 

“Our kids are staying up way too late every night to come to games – and then they’re sleeping on a tour bus for three nights a week,” the Long Island lefty reliever told The Post.

“It’s definitely a unique situation, but pretty cool nonetheless,” he said ahead of the Fall Classic vs. the Brewers, which begins Friday night in Milwaukee. 

Matz’s wife of almost 10 years and her siblings, Madison and Logan, make up the hit Christian contemporary group CAIN, which he said has let her “live out her dream of touring the country and playing in front of thousands of people.”
