[UmpJM]

Geez,

Don't you basketball guys know how to look stuff up?

The NCAA 7:

C) In the situations listed below, a partner who is 100 percent certain he has additional information unknown to the umpire making the call should approach unsolicited and alert the other umpire to such information.

However, the ultimate decision to change a call rests with the calling umpire.

1) Deciding if a home run is fair or foul.
2) Deciding whether a batted ball left the playing field for a home run or ground-rule double.
3) Cases in which a foul tip is dropped or trapped by the catcher.
4) Cases in which a foul fly ball is caught or not caught.
5) Cases when an umpire clearly errs in judgment because he did not see a ball dropped or juggled after making a tag or force.
6) Spectator interference plays.
7) Balks called by an umpire who clearly did not realize the pitcher's foot was off the rubber.

The MLBUM 6:

(3) In a limited number of situations, a partner may have critical information that is unknown to the umpire making the call. When the partner is certain that the umpire making the call could benefit from such additional information, the partner should alert the other umpire that there is additional, important information that should be shared. While the mechanics of bringing this information to the attention of the umpire who made the call is left to the crews (walking towards the partner, inconspicuous signal, etc.), crucial, potential call-changing information should not be withheld on a play that has clearly been missed. As noted in the Official Baseball Rules, "Each umpire team should work out a simple set of signals, so the proper umpire can always right a manifestly wrong decision when convinced he has made an error."

Nevertheless, the ultimate decision to change a call rests with the umpire who made the call.

Plays such as the following lend themselves to the philosophy described above:

- Deciding whether a fly ball that left the playing field was fair or foul.
- Deciding whether a batted ball left the playing field for a home run or a ground-rule double.
- Cases where a foul tip is dropped by the catcher, causing it to become a foul ball.
- Cases when an umpire clearly errs in judgment because a ball is dropped or juggled after making a tag or force.
- Spectator interference plays.
- Balks called by an umpire who clearly did not realize the pitcher's foot was off the rubber.
