I understand the Brewers perspective and have no issue with the move. If there is a bad precedent, and not a terrible one by any means but not a good one either, it is the impact on Hernan Perez. Perez worked really hard to improve his conditioning/strength/diet, has done everything asked of him (played six different positions including RF where he had never played before), and now may not have a position for him next year. He's not perfect by any stretch - he still needs to learn to lay off the low outside pitches - but if there is a person who has earned anything on this team it is Perez. He can play RF for now, but what about next year if/when Santana is back? Wren has earned his shot as well. Next year if you have Braun in LF, Wren in CF, and Santana in RF - with Villar at 3B, Arcia at SS, Gennett at 2B - Perez is the odd man out unless Carter is not back or Santana has elbow surgery (a distinct possibility). He can be a super-sub, but I think that regular playing time this year has helped with his production. Not knowing if you'll be in the lineup on any given day isn't the easiest thing for a young ballplayer. Not the worst problem to have by any stretch, but it doesn't set a good example either and doesn't help with motivation. (And before people say he's not good, he's having a better season than Neil Walker, Brett Lawrie, Chase Utley, Joe Panik, Starlin Castro, Josh Harrison, Kolten Wong, Jed Lowrie, Chase Headley, Matt Duffy, and is on par with Jose Ramirez, Javier Baez, Kang, Todd Frazier, Maikel Franco, and Adrian Beltre and not far behind Rougned Odor.)
