A number of top-performing A's prospects have received promotions over the past month. Among those on the move have been RHP Casey Meisner, catcher Sean Murphy, infielder Yairo Munoz, LHP A.J. Puk and 23-year-old Cuban defector Norge Ruiz, along with many others. Of course, some have been demoted too. But I wanted to run down some of these recent moves and take a look at how these promoted and demoted players have been performing so far this season.
