The 2015 trade deadline brought back five young players for the Oakland A's, and four of them have started to make their marks in various ways. Sean Manaea and Daniel Mengden have already debuted in the big league rotation, Aaron Brooks pitched for Oakland last year and was later traded for Chris Coghlan (who was in turn flipped for Arismendy Alcantara), and Jacob Nottingham highlighted the swap for Khris Davis. And then there is 21-year-old Casey Meisner, all the way down in High-A Stockton.
After being acquired from the Mets for Tyler Clippard last summer, the 2016 season has not been kind to Meisner.
