The Pittsburgh Pirates were beaten badly on Friday, September 11, 2026, dropping a 12-2 decision to the Chicago Cubs at Wrigley Field. Pittsburgh's pitching staff could not contain a Cubs lineup that raked for 12 runs on 17 hits across nine innings, while the Pirates offense managed just two runs against Shota Imanaga and Chicago's bullpen. With a 10-run margin of defeat in a division game, this one stings — and it was never really close after the early innings.

Pirates Pitching Collapses in Blowout Loss to Chicago Cubs

The story of this game was Pittsburgh's inability to keep Chicago off the board. Starter Wilber Dotel lasted just two innings, allowing three earned runs on four hits before exiting. Things got significantly worse when Khristian Curtis took over, surrendering six earned runs on six hits across three innings of work. By the time Antwone Kelly closed out the final three frames, the damage was already catastrophic — Kelly himself gave up three more earned runs on six additional hits. In total, the Pirates pitching staff allowed 16 hits and 12 earned runs on the night. There is no dressing that up.

Imanaga Dominates, Cubs Bats Do the Rest

On the other side, Cubs left-hander Shota Imanaga was sharp through six innings, holding Pittsburgh to two earned runs on five hits while striking out four and walking two. He picked up the win. Chicago's offense backed him up with a balanced, multi-contributor attack that made this a mismatch from the middle innings on.

Chicago Cubs Key Performers

  • Alex Bregman: 3-for-4, 1 home run, 2 RBI
  • Seiya Suzuki: 3-for-5, 1 RBI
  • Michael Busch: 2-for-4, 3 RBI
  • Nico Hoerner: 2-for-5, 1 RBI
  • Carson Kelly: 2-for-3, 2 RBI

Bregman's home run was the kind of blow that punctuated what was already a rough night for Pittsburgh. Five different Cubs recorded multi-hit games, and Chicago spread the damage across the entire lineup rather than relying on one big inning from one player. That kind of production against a shaky pitching staff is a recipe for exactly this result.

Pirates Offense Produces Little Against Chicago Arms

Pittsburgh's brightest spots were limited. Bryan Reynolds provided the lone home run of the night for the Pirates, going 1-for-3 with a solo shot and one RBI. Konnor Griffin was the most active Pirates bat with a 2-for-4 line, though he did not drive in a run. Two runs on the night against a Cubs pitching staff that included three relievers following Imanaga tells you everything you need to know about Pittsburgh's offensive output.

Turning Point: The Middle Innings Collapse

The game unraveled decisively when Khristian Curtis entered the game. Allowing six earned runs in three innings against a division opponent on the road is the kind of outing that defines a rough stretch. Pittsburgh fell behind by a margin too large to recover from, and by the time the late innings arrived, the outcome was settled. The Cubs' ability to keep putting up crooked numbers on the scoreboard made this feel even more one-sided as the game wore on.

What's Next for the Pirates

Pittsburgh remains in Chicago to continue the series. After a loss this lopsided — a 10-run beating in a division matchup — the Pirates need a bounce-back performance in a hurry. Pitching depth and consistency will be the storyline to watch as this series continues. The Cubs showed Friday night that they will punish any lack of command or soft contact, and Pittsburgh's staff will need to be sharper if the Pirates are going to avoid dropping this series early.
