Castellanos wasn't that bad defensively at Wrigley, he actually benefited from the shortened field according to fangraphs. All about mitigation... his defense is slightly below average once you put him in a shortened field, I believe it was -0.8 in LF (small sample).... -5.2 overall between DET/CHC... Not nearly as bad as his -12.9 2018. His bat translates the best to the Cell.... Doubles hitter than turned into HR's with a shortened field.... which showed at Wrigley.
