Unless "knocking up" means something different in NY than it does on the west coast.
How do you think A-Rod would “knock up” a 14 yr old without committing statutory rape?
Statutory
Statutory rape is not a joke.
So you think a 14 yr. old girl is capable of giving consent to sexual relations with a world famous baseball player probably 20 yrs. older than she?
Well if Alex Rodriguez got the little girl pregnant during the baseball game as the joke went, how exactly would that have occurred? Since she's only 14, she can't legally consent to sex with an adult man under any circumstances. Were the joke to be true, Mr. Rodriguez would be facing felony child rape charges in New York. Also, even if the little girl were above the age of consent there is nothing whatsoever to suggest that she would consent to having sex with Mr. Rodriguez during the ballgame.
Even if the girl in the joke were an adult, the suggestion that she would willingly have sex with some celebrity baseball player at the game is a very slanderous and rude comment. I am sure that most of the guys in attendance at the ballgame would consider such a joke about their wife or girlfriend to be "fighting words". Such a joke about their teenage daughter would probably start a fight instantly.
An underage child CANNOT consent to sex with an adult, so if she were "knocked up" by an adult, rape is defacto.
