2010 IOWA SOFTBALL ADAPTATIONS
The 2010 National Federation Rule Book will be used, subject
to the following adaptations:
- LEGAL BALLS - All levels of play (7-12) shall use the
optic yellow softball. In regional and state tournament games, the
Dudley SB12 LRF Y FP ball shall be used.
- LEGAL BATS - Rule 1-5 regarding bats will be
followed with the following modification to 1-5-1d: Bats must meet the 2004 ASA Bat
Performance Standard, bear the 2004 certification mark, and not be listed
on the ASA non-approved bat list.
Bats made entirely of wood are permitted and need not bear an ASA mark. Bats with the 2000 certification
mark are ILLEGAL.
3.
DOUBLE FIRST BASE - The following
provisions shall supersede Rule 8-10:
-
The batter-runner may use the colored base on her first
attempt only at first base.
-
Once the runner passes first base
she must use only the white base. The
colored base is then treated as ground.
-
The defensive player must use the
white base in making any play at first; except on a dropped third strike, the
defensive player may use the colored base for the put-out throw from her
teammate. In this case, the
batter-runner may run in fair territory when the throw is coming from the foul
side of first base, and if hit by the thrown ball, it is not interference
unless intentional.
-
If the batter-runner does not use the colored base and contact
occurs with the first baseman, the runner shall be primarily responsible for
the contact.
-
If the batter-runner does use the colored base and contact
occurs with the first baseman, the first baseman shall be primarily responsible
for the contact.
-
The double first base is required
for all games.
- OBSTRUCTION PENALTY - The obstructed runner
shall be awarded a minimum of one base beyond the last base legally
touched prior to where the obstruction occurred. If the obstructed runner is put out after passing the
base she would have reached had there been no obstruction or the base she
would have been awarded on the obstruction penalty, the obstructed runner
will be called out, and the ball remains live.
- PITCHING RULE - All levels of play (7-12) will
pitch from 43-feet beginning summer 2010. We will follow Rule 6 with the following exception: Prior
to starting the delivery of the pitch, the non-pivot foot must be in
contact with the pitching plate.
- CHINSTRAPS - Chinstraps are required on all
batting helmets and must be snapped and worn properly.
- FENCE COVERING - Any fence that is less than six
feet high and made of metal/steel shall be covered with a protective
covering. This now includes all fences on the diamond. There
is no specific color required.
- UNIFORMS - We will follow Rule 3-2 regarding
uniforms with the following exceptions:
-
There shall be no advertising or
sponsorŐs name on the uniform.
-
If worn, headbands shall be any
color or multi-colored, and do not have to match among teammates.
- PRE-GAME INFIELD - VARSITY ONLY - For regular
season dual competition and regional tournament, both teams may take infield practice on the
actual playing diamond. There is a seven-minute limit. The
timing shall be done by the home management - preferably by the PA
Announcer or scoreboard operator. A reminder shall be issued with
one minute remaining. A team still has the option of hitting
ground balls in front of their dugout in foul territory during their
seven-minute warm-up time if they prefer. But both teams must be
afforded the opportunity to use the playing diamond for their seven
minutes if they choose. Regular season tournaments and sub-varsity
warm-up protocol remains at the discretion of the home management.
- UMPIRE ATTIRE - Umpires shall wear a white or
powder blue collared shirt and grey slacks during the regular
season. A white collared shirt and grey slacks are required for all
regional and state tournament games. The white polo shirt with the
red or navy side inseam is allowed during regular season and in the
tournament series (during tournament series, all umpires shall dress
alike).
- GAME-ENDING PROTOCOL - It is permissible to use
a 12 run differential rule after 3 or 4 innings (2.5 or 3.5 innings if the
home team is leading by 12 or more runs) and a 10 run differential rule
after 5 or 6 innings (4.5 or 5.5 innings if the home team is leading by 10
or more runs).
- INTERNATIONAL TIE-BREAKER - When used in a
regular season game, the international tie-breaker rule starts in the
top of the 8th inning. To apply the rule, determine the
first legal batter and then place the player immediately preceding her in
the line-up on second base with no outs. If used during a regular
season tournament, it is permissible to begin using the international tie-breaker
rule prior to the 8th inning if the time limit has expired.
Reminder—the international tie-breaker is NOT used during the
regional tournament but is used in the Wednesday consolation bracket at
the state tournament.
- SUSPENDED GAME - Apply Rule 4-2-1 and 2 to
determine if you have a regulation game with a winner decided. If
not, the game shall be suspended at that point and if made up at a later
time, the game shall be resumed from the point of interruption.
- PROTESTED GAMES – Rule 4-4-1 – The
IGHSAU does not recognize protests.
