A Week in Purple Turns to Baseball’s Final Four, With the MLB Championship Series Starting Sunday

Sunday’s “This Week in Purple: Long Division” roundup turns from regular-season narrative to postseason stakes, as Major League Baseball moves into the Championship Series phase. The key change is straightforward, the League Championship Series formally begins with two best-of-seven matchups to determine each circuit’s representative for the Fall Classic.

For Rockies fans, the framing matters even when the team is not a participant in the final four. Coverage like this typically becomes a lens on what the organization’s offseason decisions are built around, how the sport’s most important roster profiles are being constructed when games get tighter, and what kinds of pitching and lineup depth separate contenders from the rest.

The Yahoo Sports item also reads like a calendar marker, the idea being that the postseason picture narrows quickly from division races to the last series standing. Once the Championship Series starts, each game places a premium on late-inning performance, starting-pitcher efficiency across multiple looks, and bullpen management under escalating pressure. Those themes often echo what clubs across the league emphasize heading into the next recruiting and roster-building cycle.

Still, it is important to separate what is confirmed from what is context. The available excerpt centers on MLB’s Championship Series beginning that day, but it does not provide additional, specific details such as the matchups, rotation plans, or any Colorado-focused transaction or roster development that would require verification.

If you are tracking the Rockies indirectly through this stage of the season, the watch items are more structural than team-specific. Look at how the teams in the Championship Series handle high-leverage relief, whether lineups lean into matchup-based platooning, and how often managers are willing to adjust their batting orders once the first two or three games reshape the series.
