Klump, here is what ATEC and NCAA scoring guides say about RBIs:
[FONT="]ATEC:[/FONT]
[FONT="]"One run batted in is scored for each runner who scores on a batter's[/FONT]
[FONT="]a - safe hit,[/FONT]
[FONT="]b - sacrifice bunt or fly - if a runner gets into a rundown dining the[/FONT]
[FONT="]sacrifice bunt or fly, then scores, no RBI is awarded,[/FONT]
[FONT="]c - ground out (not the third out of the inning),[/FONT]
[FONT="]d - fielder's choice,[/FONT]
[FONT="]e - walk with bases loaded,[/FONT]
[FONT="]f - being hit by a pitch with bases loaded,[/FONT]
[FONT="]g - being awarded first base because of interference or obstruction[/FONT]
[FONT="]when the bases are loaded,[/FONT]
[FONT="]h - homerun (include batter as one RBI),[/FONT]
[FONT="]I - ball in play, which caused an error only if the runner would have[/FONT]
[FONT="]scored without the error,[/FONT]
[FONT="]1) with a runner on first or second base where an error[/FONT]
[FONT="]occurs on fielding an outfield ground ball, or throwing to[/FONT]
[FONT="]a relay, credit an RBI only if the runner would have[/FONT]
[FONT="]scored without the error,[/FONT]
[FONT="]2) if an error occurs in the above-mentioned situation,[/FONT]
[FONT="]do not assume a perfect throw would have been made[/FONT]
[FONT="]at the plate (give the batter the benefit of the doubt),[/FONT]
[FONT="]3) we can never assume a perfect throw when throwing[/FONT]
[FONT="]off balance,[/FONT]
[FONT="]4) on an infield error on a play at another base, credit[/FONT]
[FONT="]an RBI only if there were less than two out,[/FONT]
[FONT="]5) on a play at the plate where the run scores because[/FONT]
[FONT="]either the throw is wild or the catcher never has clear[/FONT]
[FONT="]possession of the ball ("bang-bang" play), an RBI is[/FONT]
[FONT="]scored as well as a sacrifice fly,[/FONT]
[FONT="]6) no RBI is credited if the batter is out as the second[/FONT]
[FONT="]out of a force double play, or would have been out had[/FONT]
[FONT="]the receiver handled the ball, or if a reverse force[/FONT]
[FONT="]double play occurs,[/FONT]
[FONT="]7) if a runner rounding third base stops, notices a[/FONT]
[FONT="]misplay, then advances and scores, no RN is credited,[/FONT]
[FONT="]j - an RBI can be scored on a third out that is not a tag play only if[/FONT]
[FONT="]that out is off a fly ball or line drive, the throw beats the runner to the[/FONT]
[FONT="]base she is tagging up at, and the scoring runner crosses home plate[/FONT]
[FONT="]before the third out is made,[/FONT]
[FONT="]k - a game winning RB! is the RBI that gives the team the lead that is[/FONT]
[FONT="]never lost, (there is not always a GWRBI)."[/FONT]
[FONT="]NCAA:[/FONT]
[FONT="]"14.2.25 Run Batted In: Credit given to the batter for each run
that scores as a result of: a batter’s safe hit (including a batter
scoring on a home run), a sacrifice or sacrifice fly, a ground out,
a double play, a fielder’s choice, a walk with the bases loaded,
a hit by a pitch with the bases loaded, or defensive obstruction
with the bases loaded."[/FONT]
[FONT="]I'm pretty sure these are the most current versions of both scoring guides.
