Hustle!!! Don’t walk from position to position.
Don’t get too close (it explodes). Always trade angle for distance!!!
Stop to make a call & keep head still. (camera still)…
Always watch the ball. Chest up to ball. (It will take you to the play)…
Take your time making a call. Make sure you get it right. (Talk or consult rule book if needed…)
Make multiple calls in chronological order…
Don’t over commit (stay in WORKING AREA)…
Don’t over sell the obvious calls. Sell the close ones.

Make calls quick (w/ multiple runners) in case of next throw.
With multiple calls, do them in chronological order.

PREGAME (while dressing)
Fly ball coverage. (The Vee)
Touch & Tag responsibilities (UIC: 3rd & home and U1 has 1st & 2nd)
Bounding ball down the line (UIC up to front edge of bag)
Rotations (signals)
Call balks if you see it (angles)

10. COMMUNICATION (cont) Between Innings (keep game moving)
Keep each other relaxed
Talk about mechanics and communication
Don’t talk about critical (heated) calls or arguments
Discuss any possible problems coming up
During play (can’t be too loud)
Home plate umpire does most of the talking (base umpire reacts)
Except when field umpire is leaving the infield or working in foul territory…

11. ROTATION SITUATIONS UIC will come up about half way to 3rd in foul.
How to rotate in a two man system…
UIC will come up about half way to 3rd in foul.
Decide to commit to 3rd only if ball and runner are coming to third…
Don’t yell tell U1 until you are committed to third or heading back home. COMMUNICATE ea. time…
Flair into fair (infield grass) to make 3rd.
Be ready to rotate back home in case of overthrow. (May have to call play at plate in fair territory.)
UIC only makes calls on plays when runner is coming into 3rd. If throw behind U1 has that call.

12. ROTATING TO THIRD ?

13. ROTATION SITUATIONS
There are 4 situations when UIC is supposed to rotate to up to third base
In two man, you must read. Only go if the ball and runner are coming to third
In three or four man you go all the way up no reading (NO DECISION MAKING!!!).

14. ROTATION SITUATIONS (cont)
Situation #1: No one on with a triple (HS)
Signal: rotate hands or point to 3rd
When: Batter Runner hits a triple
Rotation: UIC man comes up to third on ball hit to fence (stay foul, let ball and runner take you into fair territory). Field umpire needs to be prepared to cover home on the in the park homerun. COMMUNICATE!!!
May want to discuss this in pregame…

15. ROTATION SITUATIONS (cont)
Situation #2: 1st only (any outs) (All levels)
Signal: rotate hands or point to 3rd
When: on clean hit
Rotation: UIC man comes up to third on ball hit to outfield (stay foul, let ball and runner take you into fair territory).
Exception: Reverse rotate if ball hit down right field line and UIC has to rule on diving catch or fair/foul. COMMUNICATE!!!

16. ROTATION SITUATIONS (cont)
