Police say Rodriguez, 28, attacked Carlos Pena, 53, outside a lounge reserved for players’ families. He is charged with third degree assault.

So what sparked the incident?

According to the Daily News, K-Rod threw the first punch in defense of his mother, who was also present.

The News quotes Pena as telling the relief pitcher to “man up and play better.” Apparently not one to let someone talk to her son that way, Rodriguez’ mother told the older man to “shut up,” and a Spanish screaming match between the two resulted.

“You can’t talk to my mami that way!” Rodriguez shouted, sparking the brawl which resulted in cuts, bumps and bruises for Pena – and a restraining order for Rodriguez, issued on behalf of his wife and her father.

K-Rod is also barred from seeing his twins until he goes to family court.
