Starting today at 3 pm ET, MLB and Domino's Pizza is offering a Domino's Medium 2-Topping Pan Pizza for free, as Jake Arrieta of the Chicago Cubs has pitched a no-hitter. (You'll need to be signed into your MLB.com account. Don't have one? It's free to sign up.) That's tied with our mention from last week as the best no-minimum purchase freebie offer we've seen from Domino's this year.
