The Bad Week Has Arrived. The Numbers Confirm What the Standings Are Still Hiding.
Two weeks ago I wrote that this Cubs team was one bad week from a crisis. Last week I noted the bats had arrived — and warned they'd better stay, because the pitching infrastructure couldn't carry any weight on its own. The bad week is here. The standings say 70-52 and a playoff spot. The runs-allowed column says something considerably darker.
Over their last 10 games, the Cubs are surrendering 5.6 runs per game. That is not a slump; that is a structural failure. Over the prior 20 games, they were holding opponents to 2.9 per game — a number that made the deadline acquisitions look like savvy margin-building. The gap between those two figures, nearly three full runs a night, is the entire story of where this team stands right now. The offense has responded, scoring at a slightly better clip than before, but the arithmetic doesn't work: you cannot bleed nearly six runs a game and win consistently in September baseball, not with a magic number of 45 and 40 games remaining.
The rotation context makes this worse. Jameson Taillon carries a 7.25 ERA across 18 starts — a number so far above functional that his presence in a playoff-bound rotation represents genuine risk every fifth day. Edward Cabrera is at 6.12. Shota Imanaga, the nominal anchor, is 10-10 with a 3.87 ERA — respectable, not dominant, and not the kind of top-of-rotation force that can mask what's happening beneath him. Javier Assad at 3.59 is the rotation's best arm, but he's the exception that proves the rule. Matthew Boyd's workload has climbed sharply over recent starts — a sign of a staff running out of options, not one deploying its depth with confidence.
The bullpen, which I flagged in August as the team's only reliable constant, is no longer that. Clay Holmes was acquired at the deadline specifically to shore up relief depth. He is on the 60-day IL. That piece from August 9th — the one that called his injury a harbinger, not a footnote — looks more prescient by the day. The one genuine bright spot in the relief corps is Ryan Rolison, who has been remarkable with a 1.02 ERA across 33 appearances. But one reliever, however good, cannot absorb the damage a broken rotation produces night after night. He is a tourniquet on a rotation that needs surgery.
Fourteen players on the injured list, nine of them on 60-day assignments — this is not a team navigating adversity. This is a team that has lost its margin entirely. The run differential over the last 10 games sits at +0.1 per game, which sounds neutral until you remember that just days ago this team was riding a 2.7-run-per-game advantage and feeling like a legitimate October threat. That advantage didn't erode. It collapsed. The Cubs are still in the fourth NL seed, but they are defending it with a pitching staff that is actively deteriorating, not stabilizing. The next two weeks will not lie.
