Firehouse Subs is now the Official Sub of Major League Baseball — and that means “Extra Innings, Extra Subs” is officially in play. (The deal is the sub shop’s first national sports league partnership in its 31-year history.)
For the remainder of the Major League Baseball 2026 season, fans have a reason to be excited for extra innings.
Any time an MLB game goes into extra innings on a Friday, Saturday, or Sunday, all baseball fans across the country can score a FREE medium sub with the purchase of another medium sub.
The freebie is redeemable the following Monday, Tuesday, and Wednesday at participating Firehouse Subs locations.
You redeem it through the Firehouse Subs’ website or mobile app,
Add two medium subs to your cart, and use the promo code EXTRA at checkout.
