PCA Is Two Steals From a Cubs First — but the Bullpen Is the Real October Question

The Milwaukee Brewers clinched their fourth straight NL Central title this week, and they did it in part by watching the Cubs lose to Atlanta. That's the headline nobody in Chicago wanted. But buried underneath the division coronation is the more interesting story: Pete Crow-Armstrong is two stolen bases away from a 40-40 season — and, if he gets there, the first in Cubs history.

Crow-Armstrong sits at 45 home runs and 38 steals through 156 games. He's hitting .280 with a .371 on-base percentage and a .949 OPS, with 30 doubles, 8 triples, 107 RBI and 118 runs scored. Over his last 30 days he's been even louder: a .284 average, 13 homers, 27 RBI and a .965 OPS across 27 games. The 40-40 marker is a formality at this point — the question is whether he adds to it.

He's also, by the numbers, the National League MVP favorite. One bookmaker lists him at -10000 (99.0% implied), another at +450 (18.2% implied) — a wide split that reflects how much the market is still wrestling with Shohei Ohtani's biceps injury. Ohtani remains on the injured list, and the Dodgers expect him back before the postseason. If he returns and rakes, the award conversation tightens. If he doesn't, Crow-Armstrong has already built a résumé that's hard to argue with.

He isn't doing it alone. Alex Bregman has been a monster in the second half — 26 homers, 89 RBI and an .804 OPS on the season, with a .900 OPS and eight homers over his last 30 days. The two combined for a feat against Atlanta that MLB hadn't seen in nearly 70 years, which is the kind of sentence that usually precedes a highlight reel and not much else. This time it's attached to a team that might actually matter in October.

The offense is carrying a compromised pitching staff

Here's where the Cubs' week gets less fun. Chicago's team ERA is 4.37 with a 1.33 WHIP, and the bullpen is worse: a 4.50 ERA, a 1.426 WHIP and 12 blown saves against just 13 saves. The injury list is a wall of arms — Justin Steele, Cade Horton, Ben Brown, Hunter Harvey, Porter Hodge, Phil Maton, Shelby Miller and Trent Thornton are all on it, most of them long-term.

The recent trend line is slightly friendlier than the season line. Over the last five games the Cubs have posted a 3.95 ERA and a 1.058 WHIP, versus a 4.756 ERA across 20 games. That's real improvement, but it's also five games. The over has hit in eight of their last ten by the team trends, which tells you these games are being decided by offense, not pitching.

And the offense is capable. The Cubs have scored 835 runs on the season against 683 allowed, a plus-152 run differential that's the best argument for them being better than their 87-69 record suggests. They've gone 6-5 over their last 11 while outscoring opponents 64-43, including a 9-1 road win over Cincinnati on Sept. 20.

What it means for the next six games

The Cubs are locked into the wild card picture, jockeying with San Diego and Philadelphia for positioning. They won't catch Milwaukee — they're 4-6 against the Brewers head-to-head and 11 games back in the loss column. So the final week is about seeding and health, not a division chase.

The story of this Cubs week is the split between what Crow-Armstrong is doing and what the roster around him can support. A 45-homer, 38-steal center fielder with a plus-152 run differential behind him is a genuinely dangerous October team. A 4.50 bullpen ERA is how that team goes home in the wild card round. Both things are true, and the next six games are the last chance to tilt the balance.
