I was bored, so I counted up the Papa John's wins. Unless I counted wrong, there were 35 games where you could redeem the half-off pizza. That means you've had a 22.4% chance of pizza this season.

People in Phoenix have been able to cash in on half-price pizza 75 times this season. They don't have the 7 run condition as part of their deal, just the W.
