Cubs playoff push turns on magic-number math and a shrinking regular-season schedule

As the Cubs move through the late-season playoff race, their magic number and remaining schedule explain what still has to happen before a postseason berth is secured.

Chicago · September 16, 2026

The Chicago Cubs’ playoff race has entered the stage where every result changes the math. NBC Chicago’s latest Cubs playoff updates focus on the team’s magic number, its remaining schedule and where the club stands in the National League postseason picture.

For Chicago-area fans, including those in the northwest suburbs, the key takeaway is simple: the Cubs are not just chasing wins in isolation. They are also watching how the teams behind them perform, because both outcomes affect how quickly a playoff spot can be clinched.

What the magic number means

A baseball magic number is the combined total of a team’s wins and its closest challenger’s losses needed to clinch a specific outcome, such as a playoff berth. If the Cubs win, the number drops. If the relevant chasing team loses, it also drops. If both happen on the same day, it can fall by two.

That is why the number can change quickly during the final weeks of the season. It is also why a single Cubs loss does not necessarily damage their position if a rival also loses, and why an off day can still improve their outlook if other results go their way.

Why the remaining schedule matters

The Cubs’ upcoming opponents matter because the playoff race is not only about the standings snapshot. It is about how many games remain, where those games are played and whether they come against direct competitors, division opponents or teams already out of contention.

Late-season series can carry extra weight when they affect tiebreaker scenarios or the standings of teams clustered around the Wild Card race. Home games at Wrigley Field may also matter for crowd energy and travel rhythm, but the standings will ultimately be decided by wins, losses and results elsewhere in the league.

What the data shows

Official MLB standings provide the baseline for the Cubs’ playoff position, including record, Wild Card placement and games separating teams in the race. NBC Chicago’s coverage adds the local context by translating those standings into the magic-number watch and identifying the schedule stretch that could determine when, or whether, the Cubs clinch.

The most important data points for readers to monitor are the Cubs’ record, the record of the nearest team that could catch them, the number of games remaining and the head-to-head or league tiebreaker rules that may apply. Because MLB standings update daily, any published magic number should be treated as time-sensitive.

Why it matters in Chicago

A Cubs playoff berth would extend the baseball season for one of Chicago’s most closely followed teams and keep attention on Wrigley Field into October. It also affects local sports media coverage, ticket demand, neighborhood activity around the ballpark and the viewing plans of fans across the Chicago metro area.

For Schaumburg and suburban fans, the practical impact is mostly in planning: game times, broadcast windows, possible postseason travel, and watch gatherings at homes, restaurants and sports bars. There is no need to force a separate local claim; the relevance is that the Cubs are a Chicago-area team with a broad regional following.

Uncertainties and risks

The biggest uncertainty is that the race remains fluid until the math is final. The magic number can fall quickly, stall for several days or become more complicated if rivals go on winning streaks. Weather, bullpen workload, injuries, pitching matchups and tiebreaker rules can all shape the final week, but none of those factors guarantees an outcome.

The safest way to follow the race is to check the official MLB standings and the latest date-stamped local updates after each day’s games. Until the magic number reaches zero, the Cubs’ postseason spot is still a target rather than a completed result.
