Tigers have had a number of guys that stood very straight in the box, going all the way back to Alex Avila. I never liked it, not only because it's not a very 'athletic' position to reach pitches from, but just the distance your head starts away from the zone and the resultant tendency for your head to still be moving during the swing. For sure it works for some guys, but I'm glad Tork has gone to a more typical crouch.
