Recording Streaming

This question concerns, recording sports events, especially or, in this instance, solely baseball games. When I had the satellite service, I could go to the guide click on the ball game I wanted to see and I could manipulate whether to add time to the program’s record recording time.  it appears that the schedule sets the baseball game for only three hours which is rarely enough time to cover the whole game and obviously not enough to capture any extra.  so, even though I have set the Arizona Diamondbacks as my team and I am recording every game, would I also have to record the next item in the guide in order to add time?
