Pete Crow-Armstrong just hit 40 home runs, and now the 40-40 club is staring him down

The Cubs center fielder became the first player in franchise history with 40 homers and 30 steals in a season - and with 18 games left, he needs just seven more thefts to pull off one of baseball's rarest feats.

Seven stolen bases away from history

Seven stolen bases. That's the only thing standing between Pete Crow-Armstrong and one of the most exclusive clubs in baseball. On September 6 at loanDepot Park in Miami, the Cubs center fielder blasted his 40th home run of the season against the Marlins, checking off the first half of a potential 40-homer, 40-stolen-base campaign. He has 33 steals already. Eighteen games remain on Chicago's regular-season schedule. The math is not complicated. The pressure, however, is very real.

With 33 steals on his ledger, the NL MVP frontrunner has a shot at recording just the seventh 40-40 season in MLB history. Nobody has done it since Ronald Acuña Jr. in 2023. Nobody in a Cubs uniform has come close - to any of what Crow-Armstrong is doing right now.

A franchise all to himself

Standing alone, Crow-Armstrong is the first player in Cubs history to record 40 home runs and 30 stolen bases in a season. That covers more than a century of baseball at Wrigley Field. Ernie Banks. Billy Williams. Sammy Sosa. None of them did this.

The 40th homer itself was vintage Crow-Armstrong: with the Cubs trailing 3-2 in the top of the fifth inning, he jumped on the first pitch from Marlins starter Tyler Phillips - an 84.7 mph sweeper that caught the middle of the zone. He didn't miss it.

It is also the second-most home runs in a season at age 24 or younger in Cubs history, behind Ernie Banks in 1955 with 44. Manager Craig Counsell let the moment land without overselling it. "Forty home runs - it's a hard number to get to and not many guys ever get to it in their career, so it was cool to see, and the season's not over," Counsell said. "He's got more to add to the number."

The company he keeps

Age 24. Forty home runs. Thirty-plus stolen bases. Crow-Armstrong became just the fourth player in MLB history age 24 or younger to accomplish the 40-homer, 30-steal feat, joining Ronald Acuña Jr., Alex Rodriguez and Jose Canseco. Canseco and Acuña each won MVP honors after achieving the feat. That context is not lost on anyone in the NL MVP conversation.

Only Philadelphia's Kyle Schwarber has more home runs among MLB hitters entering September, with 42. Crow-Armstrong leads the NL with a .573 slugging percentage and a .948 OPS, while batting .280 with 28 doubles and 96 RBI. His 9.5 WAR sits comfortably at the top of the league ranks. This isn't a counting-stats mirage built on a hitter-friendly park. NBC Sports' James Schiano noted that Crow-Armstrong is now the fourth player ever to reach 40 HRs and 30 stolen bases in the last ten years.

And the defense hasn't slipped. He won his first Gold Glove in center field in 2025 and has only gotten better there in 2026. He is easily having one of the best seasons in franchise history - let alone one of the most well-rounded seasons in MLB history - and his 9.5 WAR is comfortably at the top of the league ranks.

How he got here

The power surge didn't come from nowhere. After hitting 14 home runs in August alone, the MVP frontrunner entered the final month of the regular season with 38 homers. That's not a hot streak. That's a demolition. Before August, he was already in the 30-30 conversation; the month turned him into a legitimate 40-40 candidate almost overnight.

The power Crow-Armstrong is showing now is the result of a swing he has spent years learning to harness. The player himself doesn't want to get too far ahead. "I know how old I am. I know how many years I've been up here, and I also know that there will be another one that does it younger than me," Crow-Armstrong said. That's an interesting way to process a historic season - acknowledging the record while pre-emptively handing it off to whoever comes next.

What the 40-40 chase actually means for Chicago

The Cubs need this. The 2026 MLB regular season runs through September 27, with the postseason beginning September 29. Chicago is in the thick of the NL wild-card race, and Crow-Armstrong's individual production is the engine. The Cubs couldn't even complete the series sweep in Miami - Miami pulled away behind a two-run homer from Javier Sanoja and a solo shot from Heriberto Hernandez, preventing Chicago from finishing the three-game sweep. The team still needs him to carry them in September, not just to chase stat milestones.

Still, the milestones matter. Chicago hadn't had any player reach the 40-homer mark since Derrek Lee smashed 46 during the 2005 season. That's 21 years. The franchise waited through the Soriano years, the Bryant years, the lean rebuilds, and the slow crawl back to relevance. Now they have a 24-year-old center fielder measuring himself against Ernie Banks and chasing a season only six players in the sport's entire history have ever finished.

Crow-Armstrong needs seven steals in 18 games. He has averaged roughly two per week over the course of the season. The calendar is tight but not impossible - and he'll have every opportunity, since the Cubs will be playing meaningful games deep into the month.

His next scheduled home game at Wrigley is Tuesday night against the Milwaukee Brewers, a division rival the Cubs still have to fight past to lock up playoff position. The 40-40 watch will run alongside the standings race right through the final weekend.
