There are certainly many many superstitions in baseball, or "curses" as we say as Chicago Cubs fans.
This post is not intended to bore you with the simple ones like never stepping on the baseline when entering or leaving the field of play, to the rituals of digging ones stance and adjusting ones self in the batter box . . . only because I am working on a more "clever" Valentines day post so I will cut this short and just wish everyone a "safe" Friday the 13th and remind all of you that tomorrow is Valentines Day.
P.S. above card number 213 is from what year and what player; small hint . . . the front of the card has appeared in a previous post of mine.
