Kevin Gausman didn’t exactly come into Chicago with a stat line that inspires confidence.

He was 35, had just a 5-10 record, and was carrying a 4.38 ERA through 23 starts. He was also a rental, owed about $7 million for the rest of the season, and potentially only months away from free agency — or even retirement.

Still, the Cubs gave up two legitimate prospects to get him.

And almost immediately, you could see why they were willing to take the risk. In his Chicago debut, Gausman went seven innings against Kansas City, allowed just two runs, and retired 19 of the final 21 hitters he faced. His splitter did most of the damage, accounting for more than half his 96 pitches and drawing 10 swings and misses from the Royals.

Of course, one start doesn’t define a trade. But it did offer a glimpse of what Chicago thought they were paying for.

Because the Cubs weren’t really buying a 4.38 ERA. They were betting on the pitcher underneath it — the one whose underlying numbers still looked a lot like the steady, reliable starter he’s been for most of the past six seasons, and a veteran with a postseason track record few arms in their rotation could come close to matching.

The ERA Told The Ugliest Version

Gausman’s 4.38 ERA was his highest since 2019, back when Atlanta basically gave up on him and Cincinnati tried him in the bullpen. On paper, that number looks rough — like, “what are we even doing here?” rough.

But once you look past the ERA, the story gets a lot less dramatic.

His 3.51 FIP with Toronto was still solid, almost a full run lower than his ERA and not far off the 3.41 mark he put up in 2025. His expected ERA sat at 3.95. The strikeout rate dipped a bit from 24.4% to 23.5%, and the walk rate barely moved from 6.5% to 6.7%.

So yeah, there’s a little decline there — but nothing that screams “collapse.”

The bigger issue was what happened when the ball actually got put in play. His BABIP jumped from .262 last year to .313 this year, which is a pretty big swing. And the weird part is, the contact itself wasn’t even worse. In a lot of ways, it was actually better. His hard-hit rate dropped from 41.3% to 38.8%, and his barrel rate went down from 8.4% to 7.7%.

Opponents still hit .259 with a .405 slugging percentage against him, while Statcast thought it should’ve been more like .249 and .401. That’s not a massive gap, but it’s enough to nudge an ERA in the wrong direction over time.

And this is where Chicago kind of makes sense as a landing spot. The Cubs have been one of the best defensive teams in baseball this year — top of the league in Defensive Runs Saved, near the top in Statcast’s Fielding Run Value, and third in overall defensive efficiency.

That matters more than people think. A few extra ground balls turning into outs instead of singles can quietly change a start.

You saw a bit of that right away in his debut. He got seven ground-ball outs, and once Chicago’s defense settled in, the game stopped spiraling on him.

The stuff is still very much there too. His four-seam fastball was worth 12 runs above average at the time of the trade, which ranked eighth in baseball. His splitter is still nasty — 39.8% whiff rate, third among qualified pitchers, and a .263 wOBA against it.

The velocity has ticked down a bit. The fastball went from 94.5 mph last year to 93.9, and the splitter from 84.9 to 84.0. So no, this isn’t peak Gausman.

But Chicago isn’t expecting peak Gausman.

Chicago Needed Someone They Could Trust

The Cubs weren’t exactly in a position to be picky about starting pitching, especially not when a guy like Gausman popped up.

By late June, five of the six pitchers they were counting on for innings had already spent time on the injured list. Cade Horton made it all of two starts before needing season-ending elbow surgery. Justin Steele hit another setback in his Tommy John recovery. Ben Brown went down with a neck stress reaction, Edward Cabrera tweaked both his hamstring and adductor, and Matthew Boyd missed chunks of the year with a biceps issue and knee surgery.

And then there was Jameson Taillon, who struggled enough that Chicago eventually moved on from him entirely and sent him to Toronto in a separate deal.

Somehow, the rotation still didn’t completely fall apart. In July, Cubs starters actually put up a 3.47 ERA, which is better than you’d expect given the chaos. Shota Imanaga and Matthew Boyd gave Craig Counsell at least a couple of reliable arms to lean on.

But zoom out over the full season and it gets shakier. At the time of the trade, Chicago’s rotation sat at a 4.23 ERA and a 4.69 FIP. Javier Assad, Colin Rea, Cabrera, and David Peterson were all sitting in that uncomfortable range where either the ERA or FIP was pushing 4.78 or worse.

That’s fine if you’re just trying to get through the regular season. October's a different animal entirely.

Gausman came in with real playoff mileage already on the odometer — 56 1/3 career postseason innings — and he’d just helped Toronto get all the way to the World Series. In the 2025 playoffs, he posted a 2.93 ERA across six appearances.

He had his moments, too. In Game 2 of the World Series, he set down 17 Dodgers in a row before things unraveled in the seventh with back-to-back homers. Then in Game 6, he bounced back and struck out eight over six innings. Toronto still lost both games, but the bigger point was clear: he wasn’t shrinking in the moment, even against the best lineup in baseball.

Craig Counsell called him a “very dependable, battle-tested guy” after the deal, and honestly, that probably mattered just as much as anything on a stat sheet.

Because the Cubs didn’t really need another pitcher who could give them a decent start in July. They already had a few of those.

What they needed was someone they could actually trust in October — someone they wouldn’t hesitate to hand the ball to with their season on the line.

The Cubs Are Still Taking A Real Risk

Chicago didn’t get Gausman for free, and they knew that going in.

They sent over Ty Southisene, their No. 13 prospect per MLB Pipeline, and Brett Bateman, who ranked No. 21. Southisene had been getting on base at a ridiculous .431 clip across two levels this year, and Bateman was hitting .312 with a .431 OBP in Triple-A before even getting a quick cup of coffee in the big leagues with Toronto right after the deal.

So yeah, these weren’t throw-ins. They weren’t blue-chip, future face-of-the-franchise types either, but they had enough value that this wasn’t just a straight salary dump. And on top of that, the Cubs took on the rest of Gausman’s $23 million for a guy who’s basically a rental.

That only makes sense if you believe he’s pitching real innings in October.

And that’s really the whole thing here. Jed Hoyer has been on Gausman for a while now — he’s even called him a “white whale type target” for the front office. Once Toronto finally made him available and Chicago realized they weren’t getting a younger, controllable arm, they stopped waiting around and just went for it.

What they’re getting now isn’t peak Gausman. It’s not the version that ran a 3.10 ERA from 2021–2023, piled up 669 strikeouts, finished top-10 in Cy Young voting three straight years, and made a couple All-Star teams.

And honestly, they don’t need that guy.

They just need this version to hold up. Stay healthy. Keep missing bats with that splitter. Let a really good defense clean up the rest. Give them six solid innings in October.

He already showed a glimpse of that in his first start — seven innings, no panic, just steady work.
