According to a report by the New York Post, Mets’ closer Francisco Rodriguez was arrested at Citi Field on Wednesday after he went nutso on his father-in-law.

The blowup occurred just minutes after the Mets’ bullpen cost the team another game in the eighth inning in a game against the Rockies. Manager Jerry Manuel decided not to use K-Rod for a four-out save, instead using Manny Acosta, who promptly gave up a two-out granny to Colorado’s Melvin Mora.

Rodriguez, nicknamed K-Rod for his many strikeouts, allegedly clashed with the 53-year-old man at around 10:15 p.m. amid other players’ families after the Mets blew a lead to the Colorado Rockies and lost, 6-2.

The 28-year-old record-holder for most saves in a single-season was arrested and charged with assault.

“Mind your own f—king business!” the irate pitcher spewed at reporters asking about the incident.

His father-in-law, whose name was withheld, was taken to Flushing Hospital with facial bruises and a head bump.

Cops wouldn’t say whether Rodriguez is accused of slugging or shoving his wife’s father.

Let’s not jump to conclusions here – fights happen for a variety of reasons. One would think that there’s nothing that could get a son-in-law so mad that he would punch or shove his father-in-law, but maybe K-Rod’s father-in-law made fun of the goofy goggles that K-Rod wears. Who knows?

The main story here is how big of a mess the Mets are once again. Johan Santana is being accused of impregnating a woman after assaulting her on a golf course and now K-Rod is beating up family members in the clubhouse. This team went into the All-Star break feeling pretty good about life and now they’re a filthy disaster again.

Ah, the Mets.

Update: Check that, ESPN.com is now reporting that the beaten man was K-Rod’s girlfriend’s father and not his father-in-law. Either way, that’s not the best way to impress your girl.
