Bob and Ray were going on and on as to there must be something wrong with Morse, to have been taken out of the game. But, you could hear it in their voices, they were trying to talk themselves into believing it, because taking Morse out is EXACTLY the sort of thing Riggleman would do, and in fact has done plenty of times this season, including a game in which Morse already had TWO homers.
It's completely plausible that Riggleman would double switch out Morse while trailing by 1 run.
