How do teams play lineups near the end of the season? Do teams that clinch divisions basically bench most of their starters until post season? How about teams without a chance, are they still playing most of their starters or bench players?

I bet on the Twins yesterday and also the Phillies, but I was told that the Twins are still trying for the best AL record for home field advantage, so I would think they would still be playing to win.

How about pitchers near playoff times, are they still throwing like they normally would?

Sorry for all the questions, thank!
