Former professional baseball player Lenny Dykstra is catching some heat for a tweet that came through his account on 9/11 -- but Dykstra says he didn't post it.

The tweet, that’s since been deleted, reads, “#911 … Neither here nor there, but just think: If you were born on that terrible day, tonight is your last night of being jailbait anywhere in this country.”

Plenty of people were outraged, both for the tone and the fact it was on Sept. 11.

Dykstra later responded on Twitter, saying, “Nails here: The college-student intern responsible for the tweet about age of consent and 18 years since 9/11 is going to be taking a break to focus on schoolwork. I had indeed mentioned to her how quickly time had flown by. She meant no harm and will learn from the experience.”

Dykstra just moved from Linden to Livingston.
