Four-Umpire Mechanics (Rotation System)
BASIC INSTRUCTIONS TO UMPIRES WORKING THE FOUR MAN SYSTEM
Table 1
1
2
U1 and U3 Set up with both feet in foul territory with the inside foot just off of the foul line.
Starting 10-12 feet behind the fielder when in normal playing position. If fielder moves up, you
move up, but never closer than 10-12 feet from bag. If fielder moves back, reduce distance, but
always stay 1-2 steps behind the fielder.
One umpire will go out on ALL fly balls and line drives to the outfield, as well as on all batted balls
that have potential for trouble (out of play areas, spectator interference, etc.). Outfield coverage is
not required on line drives in the gap that are immediately read as not catchable and are not
susceptible to trouble such as spectator interference or resulting in an award of bases.
3
Umpires going out on fly balls/line drives to the outfield should go out as far as possible, but
MUST be stopped prior to the play. Remember angle over distance!
4
If an umpire goes out, that umpire does not return to the infield until the play is completed.
5
Whenever runner(s) are on base (other than a runner on 3rd base only), U2 will set up inside at 2nd
base. U2 may work on either side of 2nd base; depending on which side the umpire feels more
comfortable.
6
Umpires working inside at 2nd base will not go out on fly balls/line drives to the outfield.
7
Upon completion of a play where an umpire goes out on a ball, the covering umpire should not
release until the umpire who went out has returned and assumed responsibility of the runner.
8
Remember the adage, “Vacate and Occupy.” Whenever an umpire vacates his designated base,
another umpire must occupy that base.
BASIC PRECEPTS FOR ANY UMPIRING SYSTEM
1
Plate umpire is responsible for giving the pre-game conference. Follow an established, orderly
progression starting with fair/foul responsibilities, fly ball coverage for infield and outfield,
signals and positioning. An hour is not too long.
2
No umpire needs call (voice or mechanic) the obvious foul ball and the call, when made, is never
echoed by other umpires.
3
Balls off the batter while the batter may still in the batter’s box may require base umpire(s) to make
the call. However, WAIT for the plate umpire to make the call and then if you are 100% certain the
batted ball was off the batter, call “TIME”- LOUDLY.
4
The umpire that will make the fair/foul call is the same umpire that will make the catch/no-catch call.
5
Anytime a base umpire goes out to make a call in the outfield, that umpire will STAY OUT. Be set
for the touch/catch by the fielder, make the call, and continue moving away from the infield.
6
The second base umpire should move into the infield on the side opposite the direction of the ball
when required to come inside.

Fair/Foul Responsibilities
PU
The PU has the call
on both lines up to
but not including
the base.
Assumes entire foul
line when U1 or U3
abandons the line.
U1
Has the call on any
bounding ball that
reaches the front edge
of the base and any
line-drive/fly ball that
is first touched or
touches between the
front edge of base and
umpire’s chest.
Also, has the call from
the front edge of the
base t o foul pole
when going out on a
ball down the line.
U2
None
U3
Has the call on any
bounding ball that
reaches the front edge
of the base and any
line-drive/fly ball that
is first touched or
touches between the
front edge of base and
umpire’s chest.
Also, has the call from
the front edge of the
base t o foul pole
when going out on a
ball down the line
NOTE: If as the base umpire you are 100% certain that you see a batted ball touch the batter and
the plate umpire does not come up and call “Foul” or “Time”; then you should stop all play by
loudly calling “TIME”!
Make certain to give the plate umpire a chance to make the call first. Once time has been called,
you can then decide if the ball touched the batter in the box (foul) or out of the box (BR out).
