Having taken care of the players who left Arizona in 2018, and so weren’t part of the 2019 campaign, we now move on to the second stage of this comparison. This will be looking at players who were active for the Diamondbacks both in 2018 and 2019. Now, I am using a loose definition of the term “active” here, to include the likes of Steven Souza, who never actually appeared for Arizona this year, due to injury. I am also including those who departed during 2019, which would be John Ryan Murphy. Let’s see how these everyone did, this year and last.
