Papa John’s goes to bat for the Siteman Cancer Center.

When the St. Louis Cardinals win, so do you and cancer research at the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine.

The day after a Cardinals win, participating Papa John’s locations will offer 40 percent off of regular menu prices for pizza or other items ordered online at PapaJohns.com.

Just use the promo code “CARDSWIN” to claim your discount throughout the 2012 season.

Papa John’s also will donate 10 percent of the sale price to the Siteman Cancer Center. Proceeds will fund innovative research aimed at advancing therapies for patients.

Last season, Siteman partnered with the St. Louis Cardinals and Sportservice to offer a limited-edition Cardinals cap, with a portion of the proceeds going to Siteman. That partnership raised more than$57,000 for cancer research.
