I was BU for a game. It was an overcast, rainy day, but we started the game and rain would not be an issue. However, we got into late innings and it was clearly too dark to continue. I struggled on the bases and while in C, F6 told F4 he couldn't see a thing. My partner and I had discussed the conditions an inning earlier when a bat went flying out of a batters hands (I'm sure because of the wetness). It was the 2nd bat that went flying. Though there was no puddling, one of the F1 fell on a delivery. After I heard F6, I went to my partner, but he wanted to finish the 6th as HT was up. If I'm sure that it is unsafe, but am clearly not the UIC, what do you do?
