For Major League Baseball’s Opening Day today, an advertiser is unlocking a paywall for rabid baseball fans. Advertising Age reports that Volvo is presenting free streaming games on Apple devices for one month.

MLB Advanced Media announced that access to MLB.TV in its iPhone, iPod Touch and iPad apps is free for all of April, thanks to the Volvo sponsorship. Android users will get one free game per day.

That’s up to a $25 value for one month’s subscription to the streaming service; users will still have to pay $14.99 for the apps.
