Jake Gyllenhaal has teamed up with America's Major League Baseball (MLB) organisation for a new cancer campaign.
The Brokeback Mountain star has filmed a public service announcement (PSA) in association with MLB to highlight the work of the Stand Up To Cancer charity.
In the video, shot at a baseball stadium, Gyllenhaal says, "In baseball miracles can happen when a team works together. The same is true with the fight against cancer - that's why MLB has teamed up with Stand Up To Cancer. Because we believe that when we all stand up together we can make cancer history. This is beyond a dream. Stand up with MLB at standup2cancer.org."
The PSA was broadcast during the MLB All-Star game on Tuesday (13Jul10) in California, at which officials held a minute's silence in honour of New York Yankees owner George Steinbrenner, who died earlier on Tuesday, aged 80.
