On second thought, the drawback to keeping Travis and optioning him is that AAA is going to be stacked next year, and you don't want Travis taking AB's/2B reps away from Biggio. So maybe he is a non tender candidate after all. He certainly should not be starting in the big leagues, and he has no use as a utility player since he only plays 2B. Maybe they will try him at other spots and hope his bat comes back? Seems like a long shot but 2019 is a year of throwing s*** at a wall.
Ideal infield next year assuming no big acquisitions is Diaz at third, Gurriel at short (only because they seem to want him there), and Drury at second. If Tulo is healthy and they actually keep him, then that complicates things, but I don't think he plays another game for the Jays.
