It is important to distinguish that the MLB regular season and the MLB postseason are NOT one in the same.
If a MLB team won all of it's games during the [regular season] then lost three games in a five game playoff [during the divisional round of the postseason] could they play in the world series?
No, this team will not proceed to the next round of the postseason if the team was defeated by their opponent during the divisional round of the postseason by losing any combination of three games. Therefore, there would be no trip to the World Series.
Their final season end record would be 162 wins and 3 losses.
The team's regular season record would be 162-0.

- Lost 0-3: 162-3
- Lost 1-3: 163-3
- Lost 2-3: 164-3
