This is the result of a good guess on my part - I had just one shot - and great work by the umpire (Dan Iassogna) and the Yankess' third base coach (Rob Thompson #59) who are both in perfect position to do their respective jobs. Thompson is properly directing the base runner, Curtis Granderson, to slide into the base since Granderson's back was to where the throw was coming from (right field.) The ump, Iassogna, is right over the shoulder of the Phillies' Placido Polanco who was late with his tag on Granderson who shows - by the way - perfect sliding form. So many guys are diving head first (including at home plate as well!) that the art of the proper foot first slide is becoming a lost skill at the Major League level.
