OPS? Surely you understand OPS favours high slugging hackers like Gallo and Arencibia, I can't imagine any other reason you would use such a verboten metric in this thread. What's actually remarkable is that Gallo can ISO around .300 and still only be a league average bat. No baseball team will keep trotting him out there if he's hitting .190 and K'ing 40% of the time, even if he's mashing at a 40 HR pace.
