How many errors was Houston credited with? Looks like he had one on the play in which he got injured. Who got charged with the error on the SB attempt? A second error for Houston, or did Frederick get charged with an error?
Sometimes, you need to spell things out in painful detail for CS. While you know what you are trying to say, you often need to connect all the dots in tickets because you don't know who's going to read it and respond.
Here's how I would have worded it:
"Good morning. Please refer to the top of the fifth inning of the 7/6 PM2 game. E. Houston was injured and removed from the game during D. Ishikawa's at bat. But three plays after he was removed from the game, he is credited in the play-by-play with a throwing error during Ishikawa's steal attempt. I believe that error should have been charged to his replacement, M Frederick. Looks like a bug in the engine that you may want to look into. Thanks."
