This came up in a practice yesterday. Runners on 1st and 2nd, no outs. Batters hits a popup and is immediately called out due to infield fly. R1 went part way and the pop up was dropped by the 2nd baseman. R1 headed back to first. 2nd baseman threw ball to 1st baseman who just stepped on the bag. R2 remained on second.
My understanding is that the runners are free to advance at their own risk. My opinion on this play was that R1 would need to be tagged to be considered out. One of the coaches thought a tag needed to be applied and the other thought touching the bag was sufficient. Please educate me.
