The riddle:

Yankee Stadium was torn down after last season and a new stadium will
be opening this year.  There will be several plaques installed in the
wall of the outfield honoring former Yankee greats (ie. Babe Ruth, Lou
Gehrig, Joe DiMaggio).  In addition, there will be plaques
commemorating four former Cardinals installed on the wall alongside
the Yankee players.

Who are these four former Cardinals and why are
they being recognized in Yankee stadium?




ANSWER:

The four former Cardinals are:
Miller Huggins and Roger Maris, who both played for the Yankees as well
as the Cardinals

and

former Cardinals and later Popes in the Catholic
Church - Pope Paul VI and Pope John Paul
