Is there an official sunflower seed of MLB?

[SlickFazzer]

Or does each team choose their own?

even umps spit the things. why sunflower seeds?

I would chew cherry blasters if I was a major leaguer.

[Bill Dozer]

Is it a dip subsitute? Like chewing gum instead of smoking?

Or does each team choose their own?

If not, sure should be. You may want to middle man yourself a deal.

It doesn't look like there is an official sponser, however here is what it says on the David sunflower seed website:

If you have ever been to the ballpark — big league or backyard — you've seen DAVID brand sunflower seeds... well, you've stepped on the empty shells any way. Ballplayers of all ages have adopted DAVID as the unofficial sunflower seed of baseball.

FWIW: You always see the David sunflower seeds buckets in the MLB dugouts
