I mean, their non-position players are...who? Rooker and Arraez? If you assume the roster next year is Garver, Kiriloff, Polanco, (new shortstop), Donaldson, Larnach, Buxton, and Kepler, with a bench of Arraez, Jeffers, Sano, Miranda, and one more, why not Rooker (assuming in this scenario he's hitting). You have flexibility to rest Kiriloff or Larnach by playing Sano at first, Arraez/Miranda can spell Polanco and Donaldson, and 1 of the 5 (except the catcher) is DHing every day anways--may as well be a Rooker that's hitting, especially because you can thrown him in left on days you have a righty facing a left-heavy lineup. Once you have any injuries (not exactly unlikely, given Buxton, Donaldson, Polanco, and Arraez' presence), it becomes even easier to find a spot. If there's 40ish PAs a game, that's almost 6500 PA's, which means 13 players can each get 498 (502 is enough to be qualified). So if one guy misses 12 games (4 PAs a game), but the other 12 all stay completely healthy, all 12 of those players will qualify for the batting title.
