Oakland lost a run in Anaheim as HP Umpire John Bacon declared A's baserunner Kyle McCann out at home after he missed home plate and was physically assisted by Athletics just-scored runner Armando Alvarez in returning to touch the missed base before the Angels had the opportunity to appeal. Was this the correct call?
Although Official Baseball Rule 6.01(a)(8) puts a runner out when "the base coach at third base, or first base, by touching or holding the runner, physically assists them in returning to or leaving third base or first base," Alvarez, who scored seconds earlier, is not a coach and the base assistance came at home plate, not first or third base.
OBR 6.01(a)(5) pertaining to recently-retired runner's interference states, "It is interference by a batter or a runner when any batter or runner who has just been put out, or any runner who has just scored, hinders or impedes any following play being made on a runner. Such runner shall be declared out for the interference of their teammate."
But with Angels pitcher Roansy Contreras appearing oblivious to McCann's initial missed base touch at home, was the home team even planning to appeal the play? Does it even matter?
According to a Wendelstedt Manual interpretation, no it does not: "A runner is out...when a member of the offensive team, other than a another runner running the bases, physically assists..."
Because just-scored Alvarez was not a "runner running the bases" at the time of the physical assistance, this is considered interference by a retired/scored runner, which puts McCann out for Oakland depriving the Angels of the free choice of a potential appeal on the missed base touch.
