One Run in 18 Innings: How the Cubs' 89-Win Season Vanished in San Diego

The 2026 Chicago Cubs won 89 games, outscored their opponents by 136 runs, and watched one of the best individual seasons in franchise history unfold in center field. Their season lasted two playoff games and produced a single run.

San Diego swept the Wild Card Series at Petco Park — 8-0 in Game 1, 4-1 in Game 2 — flipping last October's result, when the Cubs eliminated the Padres. This time the rematch ran through San Diego, and the Cubs never got a lead, never got a big hit, and never got out of the first round.

The margin was real, not imagined

This wasn't a fluke of small-sample luck so much as a collision between two trends that had been building for weeks. The Cubs went 11-15 in September with a minus-5 run differential, and the underlying numbers were worse than the record. Over their final ten games, the club hit .221 with a .291 on-base percentage and a .653 OPS. Over the last five, that OPS collapsed to .576 and the win rate fell to .200. A lineup that finished the year at .252/.338/.431 with 229 home runs simply stopped producing at the worst possible time.

The pitching staff had been patched together all season, and the bill came due. Chicago used 27 pitchers. Nine players finished the year on the 60-day injured list, including Justin Steele, Cade Horton, Ben Brown, Hunter Harvey, Porter Hodge, Phil Maton, and Shelby Miller. A bullpen that posted a 4.50 season ERA, a 1.426 WHIP, and 12 blown saves against just 13 saves was the predictable casualty. Asking that group to hold a postseason line against a hot Padres club was a tall order.

The one thing that worked

Pete Crow-Armstrong was the season. The 24-year-old center fielder hit .280/.372/.570 with 45 home runs, 41 stolen bases, 107 RBI, and 119 runs — joining the 40-40 club — while producing 9.83 WAR and 26 outs above average in center. His expected numbers largely backed the line, and his sprint speed (29.5 ft/s) and barrel rate (13.3%) both sat in the top tier of the league. Even during the team's final-month swoon, he posted an .839 OPS over his last 14 games. He was the reason this team had a playoff berth to lose.

What the exit means for 2027

The Cubs enter the offseason facing something more uncomfortable than a two-game sweep: roster turnover at the top of the lineup. Ian Happ and Seiya Suzuki are both headed toward free agency, and reporting already links Suzuki to outside bidders, with Toronto framed as a real threat. Happ's 2026 line (.218/.326/.412) was a down year, but he still walked 81 times and hit 24 homers; Suzuki's .270/.368/.473 with 26 home runs was the more productive of the two and the harder to replace.

The good news is that the injury list is also a depth chart waiting to return. Steele, Horton, Brown, and Hodge are all under club control, and a rotation that had to improvise for six months could look very different with those arms healthy behind a full season of the deadline additions. The bullpen, though, is the clear priority — 4.50 ERA and a 1.426 WHIP is not a group that wins in October.

The 89 wins were real. So was the +136 run differential. But the Cubs just learned, again, that a long season's worth of margin can disappear in 18 innings when the offense goes cold and the pitching depth runs out at the same moment. Fixing that is the entire job this winter.
