New Yorkers looking to support a good cause have a shot at catching a free baseball game for their efforts.

The New York Yankees are teaming up with New York Blood Center for a blood drive from 11 a.m. through 8 p.m. Wednesday, July 6.

The first 250 donors will get a voucher for two tickets to select Bronx Bombers home games this season.

“We are honored to partner with the New York Blood Center to support this essential cause,” said Brian Smith, Yankees senior vice president of Corporate and Community Relations. “As the region’s blood shortage continues, we encourage Yankees fans to donate blood and help their fellow New Yorkers.”

The Blood Center declared a blood emergency in May and said the area's supply currently stands at two to three days, which is well below the preferred level of five to seven days.

“We are grateful to the New York Yankees for hosting this blood drive, especially following the July 4 holiday weekend, when we typically see a drop in donations due to vacation plans and holiday travel,” said Andrea Cefarelli, senior vice president of Corporate Communications at New York Blood Center.

The New York Mets are also partnering with New York Blood Center for a blood drive on Thursday, July 7 from 12:00 p.m. to 6:00 p.m. at the NYPD’s 63 Precinct in Brooklyn.

All presenting donors will receive a free Mets T-shirt and will be entered into a sweepstakes to win six Mets tickets.

People are not eligible to donate if they’re experiencing a cold, sore throat, respiratory infection or flu-like symptoms.

An appointment and a government issued I.D. are required to enter the stadium for those looking to give blood.
