Peanuts and baseball go hand in hand.
"Buy me some peanuts & Cracker Jack, " goes the song, "Take Me Out To GThe Ballgame." Vendors hawk them in the stands, and many fans spend the whole game cracking the shells, and snacking them.
But the Seattle Mariners are banning the standard snack from one section of SafeCo Field later this summer, and Mike San Soucie and family are cheering.
San Soucie says, "I've grown up around baseball, I love baseball I want to experience it with my kids."
Till now, he hasn't been able to take 4-year-old son Nathan - a fan himself - "Raul Ibanez and Ichiro!" - to a game, because Nathan has a severe peanut allergy.
San Soucie says, "If he consumes a peanut through the intake of dust, it can cutoff his airway, hives, vomiting and it can be immediate."
So, dad wrote a letter to the Mariners, asking them to make at least one game peanut-free.
The team did better, announcing it will do two games, by cleaning and blocking off two sections on the third deck of SafeCo Field. It will also ban peanut products in nearby concession stands.
A team spokeswoman says, "We'll have people and with signage and will be able to encourage other fans to keep that a peanut free zone."
San Soucie is elated, "It will be their first Major League game..."
For big sister Madelyn, it will be her first taste of the big leagues, all because the Mariners "played ball" with a parent.
The kids agree, "Super cool!!!!"
Other teams have done this - and the Mariners say they got guidance before making the move to block off the sections.
The San Soucies say they've already bought 17 tickets for the first no peanut zone game which is on August 5th.
