Guy Ritchie struck out, but A-Rod is just stepping up to the plate.

Madonna’s fairy-tale marriage with the British filmmaker came to a disastrous end because she got way too cozy with the Yankee superstar, sources told The Post yesterday.

Alex Rodriguez was so smitten with the pop queen that they discussed opening a chain of gyms together. He even attended Yom Kippur services with her and her three children in Times Square last week – sans “Snatch” director Ritchie.

“Things got to a breaking point about a month ago,” an insider told The Post. “And they [Madonna and Ritchie] did an intensive, two-week kabbalah course. That didn’t work.”
