One of my San Marzano tomatoes has different leaves , heart shaped rather

Pretty much everything has come up now except the anaheims and jalapenos ,
but they'll get there . Some of the tomatoes are almost 4" tall now .
Hopefully I can get to the end of February before I have to go to the 4"
pots . By then I'll have my "little greenhouse" built onto the south side
of the house and will have room for them .

I've read the other replies in the thread, (and certainly agree that
it's possible that it could be a sport - but it could also be some other
things) but at 4 inches high, that is still a fairly tiny tomato plant.
How sure are you that this tiny tom. has yet developed it's proper
leaves as opposed to possibly more juvenile leaves?
