FanGraphs Weekly Mailbag: September 20, 2025

I promise, I didn’t plan to write about the 2019 Diamondbacks in back-to-back editions of this column. That year was Ketel Marte’s breakout season, and also the year they traded Zack Greinke to the Astros at the trade deadline, but otherwise, they were a mostly forgettable team. Not bad by any means — Arizona finished 85-77, second in the NL West — but nowhere near notable enough to be remembered in consecutive weeks of the same column six years later.

And yet, isn’t that the beauty of this mailbag? This is the space for you to ask any and all baseball questions that pop into your head, no matter how silly or irrelevant they may be. And as far as we’re concerned here, the 2019 Diamondbacks might just be one of baseball’s more relevant irrelevant teams. I mentioned them last week because they were the team that Gerardo Parra was pitching against on August 3 when he became the third player ever to allow five or more runs without recording an out in his only career pitching appearance.

But before we get to the 2019 Diamondbacks in this week’s installment of the mailbag, I’d like to remind all of you that while anyone can submit a question, this mailbag is exclusive to FanGraphs Members.
