They have their pride to play for. Do you expect guys who are competitive enough to make an MLB roster to just roll over because they can't make the playoffs? You have a lot of bad takes, this might be one of the silliest.
Professional athletes are great competitors, they are playing for contracts, jobs on the team next season, and stats to boost said contracts and they are going all out to win every game. That fact that you think there is something strange about a team that just got eliminated from the playoffs tonight when MIN won, giving 100% is mind-boggling to me.
