I think my favorite one was last year a guy posted a dribbler down the line and the first basemen swatted it toward the dugout. But, the ball was fair, not foul.
I’ve seen that before. It’s just a visual glitch. The opponent probably saw something completely different.
That’s a bug report right there. You can upload that clip in your report too.
Question, did the first baseman set up there as if that was the bag or was he teleported or something?
