Pittsburgh Pirates (73-73) at Chicago Cubs (81-66) | Friday, September 11, 2026 | 1:20 PM CT | Wrigley Field, Chicago, IL
I’ll admit something as a Cubs fan going into this one: I checked the Pirates’ record, saw .500, and almost didn’t bother digging any deeper. That would’ve been a mistake. Chicago is walking into this series on a four-game losing streak, and Pittsburgh is playing the best baseball of its season at exactly the wrong time for us — 8-2 over its last 10 games, clawing all the way back to .500 without its Opening Day ace anywhere in the picture. This isn’t the tune-up game a glance at the standings might suggest.
Here’s my real breakdown of today’s matchup — not just who’s favored, but why, and what it actually means for both rosters walking into this series.

The Pirates Are Good Right Now, and It’s Not Just Momentum
Let’s start with the number that actually explains Pittsburgh’s turnaround: Mitch Keller, their presumed Opening Day starter, has been on the 60-day injured list since February 1. That’s not a midseason loss — that’s a team that entered the year without its ace and has still managed to fight back to .500 by September. Whatever you think of the Pirates’ overall talent level, that’s a legitimately impressive organizational response, and it tells me this isn’t a fluke hot streak riding on scheduling luck.
The engine behind it lately has been the bullpen. Six Pittsburgh relievers combined to hold the Giants to two hits in a recent win — that’s not one dominant closer carrying a shaky group, that’s organizational pitching depth showing up in real time. Add in that Bryan Ashcraft has emerged as a legitimate front-line arm in Keller’s absence, and Pittsburgh’s pitching staff is a genuinely different animal than the one that limped through the middle of the season.
Chicago’s Injury Picture: Why Swanson’s Absence Matters More Defensively Than Offensively
Here’s where I want to push back on some of the general “Cubs are banged up” narrative floating around. Dansby Swanson has been out since August 16 with a Grade 2 left oblique strain, and he’s not back for today’s game — the target return is next week against Atlanta. But look closely at what Chicago is actually missing.
Swanson was hitting just .213 with a modest OPS before he went down, direct evidence his bat wasn’t the driving force behind this offense in 2026. What actually hurts is the glove: he ranks No. 1 among all National League shortstops — and third in all of MLB — in Outs Above Average, with a Fielding Run Value of 11 that put him firmly in Gold Glove contention. Nico Hoerner has slid over from second base and kept the infield defense elite in the interim, which says a lot about organizational depth, but Chicago’s defense — quietly one of the best in franchise history this season — isn’t fully itself until Swanson’s actual glove is back at short.
The practical impact today: Nico Hoerner at shortstop, Pedro Ramirez getting reps at second. It’s not a downgrade that shows up in the box score most nights, but it’s a real thing worth tracking as this stretch run continues.
The Pitching Matchup: A Real Strikeout Battle
Chicago Cubs: Shota Imanaga (9-10, 3.91 ERA, 152 K, 1.12 WHIP)
Imanaga’s win total doesn’t match how he’s actually pitched — a 1.12 WHIP is legitimately strong, and he’s been a consistent innings-eater all season for a rotation that’s needed exactly that. His strikeout rate has stayed steady even as his record has bounced around with Chicago’s run support.
Pittsburgh Pirates: Bryan Ashcraft (14-6, 3.65 ERA)
Ashcraft is the story of Pittsburgh’s season, full stop. Fourteen wins on a .500 team, with an ERA that’s held up all year, means he’s been the stabilizing force this rotation needed once Keller went down in February. He’s not a pure strikeout arm, but he’s been remarkably consistent start to start, which matters more than dominance when you’re trying to keep a rebuilding roster in games.
The Lineup Battle Worth Watching
Pete Crow-Armstrong has had the kind of season that deserves more national attention than it’s gotten — .279 with 31 home runs, 79 RBI, and a .550 slugging percentage that puts him among the most complete players in the National League this year. He’s the single biggest reason Chicago’s offense hasn’t completely stalled out during this four-game skid.
On Pittsburgh’s side, Brandon Lowe has quietly put together his own strong season — 27 home runs, 80 RBI — and Nick Gonzales has been hitting .310 with real on-base skills at the top of the order. This isn’t a lineup that’s going to overwhelm anyone, but it’s not the pushover roster the .500 record might suggest either, especially with Ryan O’Hearn still working back from his own IL stint and not expected until September 18.
What the Numbers Actually Say
Analytics models currently have Chicago as roughly a 63% favorite in this game, and that’s a fair reflection of the gap in overall roster talent — but it’s not the blowout number you’d expect against a team that was well under .500 for most of the summer. Pittsburgh’s recent bullpen usage and Ashcraft’s consistency are exactly the kind of factors that make win-probability models more conservative than a simple record comparison would suggest.
My Take: What Actually Decides This Game
I think this comes down to the middle innings. If Imanaga can work efficiently and get through Pittsburgh’s lineup a third time without a jam, Chicago’s deeper overall roster and home crowd should be enough to snap this losing streak. But if Ashcraft matches him pitch for pitch into the sixth or seventh, Pittsburgh’s bullpen — the actual driver of their recent turnaround — becomes a real problem in a game that stays within a run or two.
As a Cubs fan, I want to see this offense wake back up after a rough week, and Crow-Armstrong is the guy I trust most to make that happen. But I’m not dismissing Pittsburgh just because of where they sit in the standings. This team has earned the benefit of the doubt with how it’s played the last two weeks.
My Final Score Prediction: Chicago Cubs 5, Pittsburgh Pirates 3
