Major League Baseball mascots Mr. Met and the Phillie Phanatic joined sitcom star Eric Stonestreet in a new series of television ads highlighting MasterCard's "Dig In and Do Good" charity campaign. The payment platform operator has earmarked up to $4 million in donations for Stand Up To Cancer (SU2C), an entertainment community initiative that encourages collaborative cancer research and public awareness.

Stonestreet's spot features the Modern Family actor running across town to personally thank diners for using MasterCard and supporting SU2C. He joins castmate Ty Burrell and comedian Ray Romano as the newest ambassador for a partnership that has so far raised $12 million for the fight against cancer.

Another ad features the MLB mascots reliving scenes from their ongoing prank war before setting aside their rivalry long enough for lunch together. MasterCard launched the ad campaign during MLB's All Star Week, announcing plans to feature the ad in baseball stadiums throughout the country.

According to MasterCard officials, the company will donate a penny for every qualifying restaurant transaction made with an eligible MasterCard debit or credit card between July 12 and September 28, 2013. Restaurants equipped with PayPass processing systems will accrue a 2 cent donation for every contactless credit card transaction they process during the promotional period. The donations don't add any expenses to a diner's bill, nor do they interfere with rewards credit card promotions.

MasterCard and its corporate partners have also teamed up to remind cardholders about opportunities to support the SU2C by using qualifying cards instead of alternate forms of payment at restaurants. For instance, when checking in to a venue on Foursquare, the social networking platform will suggest using a MasterCard and adding to the donation pool. In addition, MasterCard and social payments startup Chirpify have announced plans to facilitate additional donations on Twitter, Facebook, and Instagram.
