Steve Carell in 'Baseball Believes' campaign

Actors Steve Carell, Colin Hanks and Ken Jeong are featured in a new "Stand Up To Cancer" campaign, titled “Baseball Believes,” filmed at Boston’s Fenway Park that celebrates amazing plays from Major League Baseball’s postseason history. The six spots, which include the actual broadcasts of the historic plays, connect believing in miracles on the playing field with a shared vision of ending cancer. The spots will begin airing in early September in stadiums, on MLB Network, FOX and ESPN. Major League Baseball is a founding donor of "Stand Up To Cancer" and, together with its 30 clubs, has committed more than $30 million to the initiative.
