The most common way to bend rods is to unbolt the jugs, and accidentally bump the jugs downward before taking them off of the pistons. The bronze rods are quite easy to bend. While running?.. very unlikely.

There are a couple of different ways the rods can be bent. Side to side won’t show up, since that’s the same orientation as the flex in the wrist pin. Up and down will show up just as you see in the photo you attached. If the shiny spot is evenly front and back, the bend was likely just up and down. If the rod is twisted, all bets are off, and you’ll need a jig to bring the rod back into alignment. The jig I’ve seen has two parallel rods, one goes through the big end, the other through the wrist pin end.
