Someone goes out on

EVERY fly ball

Fly Ball Coverage

U2 is OUT

(in E or F)

Same coverage

used in 3-Umpire

Mechanics

Fly Ball Coverage

U2 is IN

(in B or C)

8 of 54

Fly Ball Coverage

When U2 is inside (in B or C)

He STAYS inside

U2 does NOT go out for a fly ball, leave that to U1 and U3

9 of 54

U2 is the “KEY”

for rotation when U2 is OUT

10 of 54

U1 is the “KEY”

for rotation when U2 is IN

(B or C)

Just like

Umpire Positions

With a Runner on 3^rd only,

U2 should ALWAYS be on

The 3^rd base side of the field

in Position F

And here’s why….

Rundowns

If all Umpires are “IN”

Umpires assigned to the bases involved handle the rundown�

If any Umpire is “OUT”

Use Rundown Mechanics for 3-Umpires

No Matter What Happens…..or

Who misses a rotation

FILL THE HOLE !!!

We can talk about missed

coverage later……….but

SOMEONE has to MAKE THE CALL
