We don't distinguish between starters and relievers here: all appearances count equally. This obviously favors the bullpen, who can rack up twice as many games in a season as a full-time member of the rotation, but there are still a fair number on the list who were part of the rotation (though not necessarily for all their time here). You get the first and last year as a D-back to help, and as usual, last names only are fine. This one's moderately simple, so 15+ should be your goal here.
