For the 2026 MLB season, there's a sporadic promotion where we get a free 20oz. Mountain Dew Baja Blast whenever any player in any game hits a homerun at least 420 feet. Here's the official announcement of this promo if your hobby is reading corporate PR speak.
To start, you'll need to register on their site. Then if a homer is hit that triggers this freebie, you'll receive an email with a 24-hour active coupon. This coupon will give you a free Baja Blast up to $4 at participating retailers OR up to $10 at an MLB stadium.
I signed up just now and immediately got a coupon because Mickey Moniak hit a homer estimated to be 435 feet last night. Thanks, Mickey!
There are two check boxes under the registration form and you do not have to opt into marketing email alerts if you don't want.
This promo runs through 9/27/26 or until 500,000 redemptions have been reached, which occurs first.
