Jose Herrera has played a significant role as a catcher for the Diamondbacks this season, achieving the third-lowest catcher ERA on the team at 4.76. His performance indicates that some pitchers, like Zac Gallen, have shown better results when he is behind the plate, as Gallen posts a 2.82 ERA with Herrera compared to a much higher ERA with Moreno. However, Herrera's overall statistics suggest he may not be as effective as Moreno, particularly in pitch calling, as indicated by a -1 rating in terms of runs allowed above average. Additionally, Herrera’s defensive metrics show a -2 in Defensive Runs Saved, highlighting potential liabilities in his defensive capabilities. Overall, Herrera's performance raises questions about the effectiveness of the catching situation for the Diamondbacks and its impact on the team's pitching success.
