My question about this has always been, do you swap the numbers on a pitching change with no substitution. (I assume you do regardless if a sub was made or not).
In MLB you can bring in a reliever for an outfielder and stow your starter out there for a batter then bring the starter back to the mound, and I assume at every change the numbers reset because a sub would be brought in (relief pitcher goes to 1, starting pitcher to 9, outfielder out...then outfielder sub to 9, starting pitcher to 1, relief pitcher out)...
But...what if you had a player like Jason Lane or Rick Ankiel and you just swapped from outfield to pitcher without making a substitution...is the pitcher then 9 and rightfield 1 or whatever? That would be the convention for other positions. My guess would be that pitcher and catcher are always changed to 1 and 2 regardless of the scoring for other outfield players.
