Chicago Cubs (87-71) at Boston Red Sox (84-72) | Friday, September 25, 2026 | 12:05 PM CT & 5:05 PM CT | Fenway Park, Boston, MA
Yesterday was one of the best days to be a Cubs fan in years — Pete Crow-Armstrong stole his 40th base to join the 40-40 club, Chicago clinched its second straight playoff berth with a 2-1 win over Miami, and the White Sox clinched their own spot on the same afternoon. Today, there’s no time to celebrate. An incoming nor’easter has forced Chicago and Boston into a split doubleheader, and with the Cubs still locked in a three-way tie with the Phillies and Padres for the top NL Wild Card seed, every inning this weekend could decide who hosts a playoff series next week.
Here’s my real breakdown of today’s twin bill — the seeding stakes, the pitching logistics chaos, and what actually matters beyond the box score.

Why This Weekend Actually Decides Something
Here’s the stakes in plain terms: the Cubs, Phillies, and Padres are all fighting for the same thing — the top NL Wild Card seed, which comes with hosting rights for a best-of-three series starting Tuesday. Boston, on the other hand, is already locked into its own Wild Card positioning regardless of what happens this weekend, which changes everything about how both teams are approaching today’s doubleheader. The Red Sox are lining up pitchers who won’t factor into their own postseason plans, while Chicago has to balance winning games that matter for seeding against not burning out arms it’ll need next week.
The Roster Wrinkle That’s Making This Harder for Chicago
Normally, teams get to add an extra pitcher to the roster for a doubleheader. Not this time — that rule only applies through August 31, and rosters are already expanded for September, so Chicago has to cover 18 innings today with the same group that’s already been stretched by three straight games against Miami this week. That’s a real logistical disadvantage layered on top of an already-important series.
Game 1: David Peterson Draws a Murky Opponent
Peterson gets the ball for game one, and Boston still hadn’t named a starter as of Thursday night — the Red Sox’s interim staff has been openly candid about using this weekend to rest arms rather than commit to a normal rotation plan. That uncertainty actually cuts both ways for Chicago: it’s hard to game-plan against an unknown starter, but it also suggests Boston isn’t sending out anyone who’ll be sharp off a normal routine.
Game 2: A Real Pitching Matchup, With Real History Behind It
Clay Holmes has been outstanding since a midseason move to Chicago’s rotation, sitting at a 3.25 ERA and 1.16 WHIP across 97 innings. Jake Bennett has quietly had a strong season of his own for Boston — a 3.78 ERA with a stingy 20 walks allowed over more than 109 innings, reflecting real command. This is the more competitive pitching matchup of the day on paper, and with Shota Imanaga reportedly available in some capacity across this series, Chicago has real bullpen depth to lean on if either game gets tight.
The Bigger Picture Beyond Today
Whatever happens in these two games, Chicago still has to figure out its actual Wild Card rotation without knowing yet who it’s playing or where. That’s the real challenge hiding underneath today’s doubleheader — every fastball reaquires answers to two questions at once: does this help win today’s seeding race, and does this cost the team anything for next week’s actual playoff series.
What Actually Decides Today
I think this comes down to whether Chicago’s offense — fresh off clinching, playing loose, and riding one of the best individual seasons in franchise history from Crow-Armstrong — can take advantage of a Boston pitching staff that’s explicitly not trying to win in the traditional sense today. Holmes in game two gives Chicago a real edge on paper; game one is more of a coin flip given Boston’s undecided starter.
My Final Score Predictions: Chicago Cubs 5, Boston Red Sox 3 (Game 1) | Chicago Cubs 6, Boston Red Sox 2 (Game 2)
