At Connie Mack Stadium, where Jimmie foxx once hit one about 100' up Lambert Street, for a distance of 540'-550', Mickey hit a right-handed home run that went, according to accounts, 25' over the roof at the 400' mark and landing on the roof of a house on West Somerset St. across from the park.  The address of this house was 2800 N. Twentieth.  It was the corner house running along Sumerset north of left field.  Bill Jenkinson measured to a tree on that street that was exactly 100' from the corner of the intersection of those streets and 505' from home plate.  Given those dimensions and an accurate diagram of the area, Mickey's home run landed a minimum of 535' from home plate.  Unimpeded by the roof, a minimum of 542'.
