San Diego Memorial Day Senior Baseball Tournament
- This is a wood bat tournament.
must be 60 years old, or older, by December 31 of the calendar year
(since 2015 tournament, no grandfathering, no exceptions).
Players in 65+
division must likewise be age 65 by December 31.
- A/B Batting lineups (former MSBL National Rule
3g/dead link) or shared positions (MSBL National Rule 6) are allowed.
- A team manager
may bat as many players as he desires, with a minimum of 10 (subject to
the number of players available, if less than 10). Batters cannot be
deleted or skipped over, regardless of their batting position or when
they were added during the game. If a team has only 9 (nine) players and
therefore bats only 9, the opposing team will have the option of batting
9 as well. If a team has more than 9 players and still only bats nine,
they will be assessed an out each time the 10th batting position is
skipped. Batting only 9 players is NOT an offense open to protest.
- A traditional A/B lineup or Shared positions are allowed in the batting lineup. If shared positions are chosen, courtesy
runners will not be allowed. Use this definition from MSBL National Rule 6
manager uses two players to share one batting position in the offensive
lineup and during the game the manager decides who bats each time the
batting position comes up. This can be implemented at the start
of a game or can be added anytime during the game. He can then
use the other player to run if he chooses to do so. When a player
is used as a base runner in the Shared Position, he MUST bat the next
time his position in the order comes to the plate. After that
point, either of the Shared Runners may bat in this position.
There is no limit to the number of shared line-up positions. Any
player sharing a batting position is locked in that position for the
duration of the game and cannot be used in any other batting order
position. This rule replaces both A/B and courtesy runners.
If teams choose to use the A/B and Courtesy Runner instead of the
Shared Runner, they are entitled.
- In A/B or shared positions, the catcher must still come off the bases when there are 2 out.
- Round robin games are 7 innings, with a
2:15 time limit (no inning can start after 2:15).
- Playoff games are 7 innings, with no
- Base running: Substitute runners will be
allowed for catchers who are currently in the game, and a maximum of three
position players identified by each team at the start of the game.
Substitute runner(s) must be the last batted out.
that will need courtesy runners must have their manager notify the
opposing manager prior to the start of the game. If not so notified,
the opposing manager may deny the request. Each team will be allowed a
maximum of 3 players (other than the catcher currently in the game) per
game who can be run for each time that they reach base. The individual
who runs for these players needing a courtesy runner is not determined
ahead of time. It is always the last batted out who must run for the
person needing the courtesy runner. Once the game begins and the full
complement of 3 courtesy runners has not been used, if a player
sustains an injury, an additional courtesy runner may be used. In the
event a player becomes injured during the game and the maximum number
of courtesy runners have already been designated, a pinch runner must
be used and no courtesy runner will be allowed. If a batter (designated
as needing a courtesy runner) opts to run, or forgets to get a courtesy
runner and subsequently runs, he will lose his courtesy runner for the
remaining portion of the game. The offensive team that is replacing the
courtesy runner has 30 seconds to make the runner change. If the runner
is not replaced within this time period, the original runner must run
and the right to use the courtesy runner for this particular batter
will be forfeited for the balance of the game. The 30 second time limit
will begin at the time the umpire calls for time to allow replacement
for the runner.
