No, the contact call would be a manager decision. I assume Bobby Cox wanted to be aggressive. (I also perhaps erroneously assume Bobby Cox is still the Atlanta manager.) The base runner on second would not have gone on contact and should never have been between the bases: either go to 3rd or back to 2nd.
yeah - kinda sorta right
On contact play all runners go. You are risking that the lead runner might get thrown out, knowing that even if he does the trail runner gets to third.
Again - I didnt see the play - nor did I hear it analyzed - but its quite possible Riley's inexperience, lack of baserunning savvy was ENHANCED by Swanson - the more seasoned player/baserunner - getting in the rundown. Thus Swanson the key culprit - Riley the sidekick.
(Bottom line re: Riley movement - Once there is a rundown trail runner has to immediately advance, then just hope lead runner can somehow score)
