As I posted in the front page report, Jadher is a gamer. He is blocked with Pratt, Pena, Made as the high end prospect, and guys like Quintana, DiTuri and now CJ Hughes with a lot of money invested into them, not to mention Turang and Ortiz already at the big league level, Areinamo was a luxury. His ceiling wasn't as high, but he is a leader on the field, and can play any IF position very well, and has shown the ability to hit through high A and wasn't given the chance to do that a AA yet. He will get that chance, and I wish him luck. I can only hope my gut is wrong but just don't feel or see Jansen as an upgrade but I guess with Quero's injury, there will be no other internal catching options so had to find one elsewhere.
The injury bugs this year in the minors in particular have been so upsetting, they have potentially thrown off a lot of plans for internal solutions (Quero, Wilken, Boeve in particular)
