Not trying to start a fight, ma'am, but Zack was not drafted, and he is not on the same level as the pitchers on the primary roster. His conference ERA was a full two runs per game higher than either Bobby Wahl or Jonathan Crawford. He had a nice season, but his resume simply does not match up to that of Rodon or Plutko or Berg or the other primary guys.
He had a nice year, I'm very glad he's coming back, I wish him all the best, but there is NO WAY he is one of the top 1% of collegiate pitchers in the country, which is what membership on the CNT roster sort of means.
