The High-A Stockton Ports entered 2016 with the deepest starting rotation in the Oakland A's farm system. Four of the five members made our Community Prospect List Top 30, meaning that just about every day there is a legit prospect on the mound. The whole group:
RHP Casey Meisner (acquired for Tyler Clippard)
LHP Zack Erwin (acquired for Brett Lawrie)
RHP Daniel Gossett (drafted 2014, 2nd round)
RHP Brett Graves (drafted 2014, 3rd round)
RHP Heath Fillmyer (drafted 2014, 5th round)
There's a thing about pitching prospects, though.
