You said that you primarly do FP, so you were out of your comfort zone. I guess you were needed or a regular baseball ump would be doing the game. The important thing is that you "learned" something that you will never forget. There are some STUPID coaches out there! And there is a timing play in SB. You mentioned that you were mostly a SB ump, and you did not mention you had problems with the baseball strike zone. If your only mistake was the timing play thing, you did well.
Experience is a great teacher.
