I don’t actually need to sleuth the date of this game, because it’s right in this tweet, which is where I found the photo:

In fact, it’s impossible for me to tell you exactly when this happened, because in that game, won by the Cubs 4-3, Flood made three putouts. He caught fly balls by Nelson Mathews and Moe Thacker in the second inning and another one by Mathews in the fourth.
