Geometry 101

[tcannizzo]

Because the distances are measured:
a.) from the back edge of HP to the front edge of 1B
b.) from the back edge of 1B to the front edge of 2B
c.) from the front edge of 2B to the back edge of 3B
d.) from the back edge of 3B to the back edge of HP


Minimum running distances from base to base:

HP to 1B: 59 feet 5 inches (RHB)
60 feet from back edge of HP to back edge of 1B
minus 15 inches because BR must only touch front edge of 1B
plus 6 inches to account for the RH batter's box

1B to 2B: 58 feet 9 inches
60 feet from back edge of 1B to front edge of 2B
minus 15 inches because R can start at front edge of 1B and must only reach front edge of 2B

2B to 3B: 58 feet 9 inches
60 feet from back edge of 2B to front edge of 3B
minus 15 inches because R can start at front edge of 2B and must only reach front edge of 3B

3B to HP: 57 feet 4 inches
60 feet from back edge of 3B to back edge of HP
minus 15 inches because R can start at front edge of 3B
minus 17 inches because must only reach front edge of HP
