Cubs at Cardinals: Chicago looks to turn an early-series advantage into another road set win

The Chicago Cubs open their push for a series win against the St. Louis Cardinals on Wednesday night, starting a slate that matters as much for momentum as it does for the standings. The Cubs are aiming to build on the kind of early advantage that can separate road series into a “race” for one team, rather than a back-and-forth with two days left to complicate the picture.

Part of the emphasis heading into this game comes from a specific franchise pattern against St. Louis at the start of longer series. The Cubs have played at least four games in St. Louis in the National League Expansion Era era since 1962, and this matchup represents their 27th such series. According to a Take Two note included in the preview, Chicago has won the first two games of that series only five times. Those five instances include 1976, 1992, 2014, and 2023, plus the current set as the next chance to extend the list.

Even within that narrow group, the Cubs have rarely found a clean escalation from early games to full control. The same preview notes that among those five series in which Chicago won the opening two contests, only the 2023 series was the one in which the Cubs won the first three games. In other words, Chicago’s historical “best case” is both real and rare, and it is what the current series could resemble if the Cubs are able to keep their edge intact.

St. Louis has long been one of baseball’s most consistent and deep opponents in the National League, and the Cardinals’ home environment typically forces visitors to win the details. A four-plus game series can turn quickly when a team finds a way to manufacture at-bats in the middle innings, protect leverage late, or simply avoid turning a one-run game into a multi-run gap. For the Cubs, winning the first two contests is a form of protection, because it limits how many “must-win” situations are created over the back half of the set.

There is also a broader baseball feel to why this sequence matters. Series wins do not just affect one day on the schedule, they influence how a team deploys its late-inning arms, how it approaches subsequent matchups within the same homestand or road trip, and how it handles the psychological weight of knowing it can close out the series instead of needing a late rescue. Even without assuming anything about Tuesday night or the rest of the weekend, the opening two-game target described in the preview serves as a road map for what the Cubs will try to accomplish.

Wednesday’s game at 6:45 CT is therefore more than a single contest between two familiar rivals. It is the next step in a St. Louis pattern Chicago has only occasionally mastered: converting an early advantage into a series outcome when the series is long enough for variation to appear. If the Cubs can extend the early-series pattern they are chasing, it would align with the handful of seasons where the team not only started well but kept the momentum long enough to change the narrative of the set.
