re: Announcers not knowing why they subbed the left fielder

I assume just getting a stonger arm in there for a sac fly scenario. I honestly was expecting them to pull an outfielder and put in a 5th infielder or something and play for the double play, which Tommy hits into a whole bunch. With a guy like Tommy, he doesn't hit a lot of shallow fly balls. If he hits the ball in the air, it usually goes a long way and the fielder wouldn't have a chance to throw home anyways. I have seen that move work a select few times in baseball.
