Solution for SDS:
The easiest solution is- allow us to the option to “schedule to put in game” so long as the pitcher is active in the bullpen. Whether the pitcher is in “stretch and toss” mode or “warming up”, the pitcher will go in the next half inning. If the pitcher didn’t get enough warm up pitches in the pen, he goes in cold. This would solve the problem of pitchers losing stamina when they enter (so long as you do the following: “stretch and toss” “schedule to put in game” without warming them up). They will go in cold, but then 4-6 warm up pitches will have them ready and boost confidence in pitches.
This would require the least amount of work from SDS, could easily be a patch in the game. It doesn’t completely solve the glitch in the game but it allows an easy out to work around it until a legitimate fix is in place.
