Cubs Clinch Playoff Berth in Miami as Pete Crow-Armstrong Reaches Baseball’s 40-40 Club

The Chicago Cubs secured their second consecutive postseason appearance Thursday by defeating the Miami Marlins 2-1 in Miami, while center fielder Pete Crow-Armstrong reached another milestone by stealing his 40th base of the season. The achievement made Crow-Armstrong only the seventh player in Major League Baseball history to complete a 40-home-run, 40-stolen-base season.

A Milestone Night in Miami

The Cubs entered the game needing a victory to formally secure their postseason place. They got it in a tightly contested game against the Marlins, with Chicago eventually holding on for a 2-1 win.

Crow-Armstrong's achievement added another layer to the evening. He entered the game with 45 home runs and 39 stolen bases, already putting together one of the most productive offensive seasons of his young career. His 40th steal completed the rare combination of power and speed that has been reached by only a small number of major league players.

The 24-year-old had already established himself as one of Chicago's most important players before reaching the milestone. Earlier in the season, he became the 10th Cubs player to hit at least 40 home runs in a season and the first left-handed Cubs hitter to reach that mark since Billy Williams in 1970.

Cubs Secure Another October Appearance

The victory guaranteed Chicago another postseason opportunity after the club also reached the playoffs the previous year. The Cubs' latest berth comes after a regular season in which the team combined offensive production with enough consistency to remain in the National League playoff picture.

For the organization, the achievement provides continuity at a point when the club is building around a younger core. Crow-Armstrong has become a central part of that group, contributing not only at the plate but also in center field.

His defensive performance has been particularly notable. MLB data earlier in the season showed Crow-Armstrong leading the league in Fielding Run Value and ranking among the league's top players in Outs Above Average. His combination of defensive range, home-run power and baserunning has made him one of the more complete young players in the National League.

What the 40-40 Club Represents

A 40-40 season requires a player to maintain elite production in two very different aspects of the game. Home runs demand sustained power, while stolen bases depend on speed, opportunity and the ability to create additional bases without making an out.

The rarity of the accomplishment has helped make the 40-40 mark one of baseball's best-known statistical benchmarks.

Crow-Armstrong's season is particularly notable because he reached the milestone at age 24. His earlier 40-home-run achievement had already placed him among the youngest Cubs players to reach that level of power.

His progress also reflects a broader change in the way modern players contribute. Teams increasingly value players who can affect games in several ways rather than relying exclusively on one specialized skill. Crow-Armstrong's season has provided a clear example of that multidimensional approach.

Miami Becomes Part of the Story

The milestone occurred against the Marlins, giving Miami a direct role in one of the most notable individual achievements of the regular season.

For the Marlins, the loss came during a difficult late-season stretch as Chicago pursued postseason positioning. For the Cubs, however, the game became a celebration of both a team accomplishment and an individual milestone.

The matchup also illustrated how late-season games can carry significance for both clubs even when their postseason situations are different. Chicago was playing to secure its place in October, while Miami was competing against a team with increasingly high stakes.

The Cubs' victory ultimately provided the result they needed.

A New Chapter for Crow-Armstrong

Crow-Armstrong's 40-40 season now places his name alongside a short list of players who have combined substantial power with elite baserunning in the same year. MLB records show that only a handful of players before him had achieved the feat, making the accomplishment particularly unusual even in an era when home-run totals have risen.

The milestone also changes the context surrounding his season. What began as a breakout campaign has become one of the most statistically significant seasons by a young Cubs player in recent history.

Chicago now turns toward the postseason with Crow-Armstrong among the players expected to play a major role. After securing its October place in Miami, the Cubs leave the city with both a playoff berth and a piece of baseball history.
