I actually started off the season by diligently keeping a list of potential play of the year candidates from each game. However, reviewing my notes, the last entry was on June 4. Which seems about appropriate, as after that point, I mostly watched only the 2021 Diamondbacks games I had to recap. Which means that I was in a bit of a quandary when it came to writing this piece. Should I just throw it open to readers to suggest plays? Fortunately, the radically improved MLB Video Room came to my rescue. With the appropriate search filters, I was able to find the 97 plays tagged there with “defense” for the D-backs in 2021.
