R1 is on 3rd, R2 is on 1st. On the pitch R2 jogs to 2nd. F2 in no hurry finally fires the ball to 2nd. R2 gets in a run down. PU goes about halfway to 1st, yelling I've got 1. BU moves towards 2nd. After a couple of throws in the rundown, R1 at 3rd starts getting off the bag towards home. F4 fires to F5 and tags R1 out going back to 3rd.
My question, who has the call at 3rd on this? It's got to be BU. Furthermore, with the PU going up the line about halfway for a possible call at 1, who's got the plate? I ass-u-me the PU does. In our case the blues were so focused on the rundown, I think both of them forgot there were other base runners, and subsequently both caught with their pants down. Neither of them saw the play at 3.
