Gabby Schilling is playing hardball, too.

Curt Schilling, the former Red Sox ace, is on a mission to expose and punish the Twitter trolls who responded to a congratulatory message about his daughter’s college softball future with heinous, sexually explicit threats.

Gabby backed up her combative father during a joint interview that aired Tuesday morning on “Good Morning America.”

“Nobody should be able to get away with saying things like that to a father about their daughter,” Gabby said.

Curt Schilling’s campaign, which began with a lengthy blog post, has produced the school suspension of one disgusting respondent and the firing of another, who had worked as a part-time Yankees ticket taker.

“I’ll do everything I can do to not embarrass her, but I’ll never not protect her,” Schilling said in the televised interview.
