Yankees Derek Jeter, Alex Rodriguez, Mariano Rivera and Curtis Granderson have participated in a new PSA in support of Harvey Weinstein’s anti-bullying documentary “Bully.”

The 30-second clip, also featuring manager Joe Girardi, was shot during spring training at Steinbrenner Field.

The message kicks off with Jeter saying, “Thirteen million kids will be bullied in the US this year.” He later tells viewers to “visit www.thebullyproject.com.”

A-Rod adds, “I’m a New York Yankee, and I’m taking a stand against bullying.”

“When a community of people come together, we have the ability to enact positive change through our words and actions,” said Girardi said in a statement about the clip. “Bullying is a problem too powerful to ignore, and I’m proud to stand alongside so many others in raising awareness for this meaningful cause.”

Other celebs who’ve supported the film include Ellen DeGeneres, Justin Bieber, Kelly Ripa and Anderson Cooper.

Weinstein recently won a battle to get the MPAA to change the film’s rating to PG-13 from R. And the film’s director Lee Hirsch was in Washington, DC, this week meeting with officials from the White House’s Office of Public Engagement and Domestic Policy Council.
