The Cubs’ recent surge hit an abrupt wall at Wrigley Field, where the Cardinals handed them a 17-1 loss that looked nothing like Chicago’s recent form. The defeat came only days after the Cubs exploded for 23 runs against the Padres, creating an extreme swing that MLB history had never seen before, according to the Elias Sports Bureau.
Chicago had been rolling for weeks, but Friday’s opener against St. Louis turned into a reminder of how quickly baseball can flip. The Cubs entered with one of the game’s hottest lineups, yet their bats went cold while the Cardinals kept finding damage against left-hander David Peterson.
Peterson’s Wrigley debut unraveled quickly
Peterson, acquired from the Mets to help stabilize the rotation, was making his second start with the Cubs and his first at Wrigley Field. After a solid outing in his team debut against the Brewers, he ran into trouble early and often against St. Louis.
Manager Craig Counsell said the Cubs needed to keep the ball on the ground more, noting that Peterson has usually done that well in his career. Instead, the Cardinals produced hard contact throughout his 3 2/3 innings, including seven balls in play with exit velocities of at least 100 mph and four more above 95 mph.
Peterson struck out hitters at a decent clip, with nine whiffs, but he also allowed nine hits and three walks. He struggled most with two outs, giving up a three-run homer to Nathan Church in the second inning after retiring the first two batters, then later allowing two-out damage again in the third and fourth.
“I wasn’t really able to get those ground balls today,” Peterson said. “Part of it is there were probably some pitches that I left a little too much up in the zone. They put some good at-bats together and some good swings on some balls.”
Chicago’s offense cooled after a blistering stretch
The Cubs had averaged 7.4 runs per game over their previous 19 contests and went 15-4 in that span. During that stretch, they posted a .367 on-base percentage and a .504 slugging percentage, with a +65 run differential that was boosted by Wednesday’s 23-run outburst.
Against Cardinals right-hander Andre Pallante, that momentum disappeared. Chicago went 0-for-8 with runners on base during Pallante’s 5 2/3 innings, and the lineup never found the timely hit it had been producing so often over the last few weeks.
| Key Cubs Stretch | Number |
|---|---|
| Games | 19 |
| Record | 15-4 |
| Runs per game | 7.4 |
| On-base percentage | .367 |
| Slugging percentage | .504 |
| Run differential | +65 |
What stood out beyond the final score
Pete Crow-Armstrong added a double and finished 1-for-3 after opening July with a homer in Wednesday’s win. He also said he was proud of the way the team had played over the last couple of weeks, while noting that his strong month does not change what comes next.
Dansby Swanson and Seiya Suzuki have also been important drivers during the Cubs’ recent offensive run. But on Friday, the Cardinals kept Chicago quiet long enough to turn a lopsided game into one of the starkest one-day reversals the club has experienced all season.
For the Cubs, the loss was not just a bad night at the plate or on the mound. It was a full stop to a stretch that had made them look like one of baseball’s most dangerous lineups, at least until St. Louis walked into Wrigley and changed the tone immediately.
