The Cardinals’ Impressive Winning Streak Doesn’t Guarantee October Success
With a doubleheader win on Friday, a bizarre 3-2-5-4-2-8-6 double play and a ninth-inning comeback on Saturday, and more late-inning heroics on Sunday, the Cardinals ran their winning streak to a franchise-record 16 games. The streak is the longest in the majors since Cleveland won 22 consecutive games in 2017, and the longest in the National League since the Giants won 16 in a row in 1951 as part of the comeback that culminated in Bobby Thomson’s pennant-winning homer, “The Shot Heard ‘Round the World.”
The Redbirds’ winning streak has turned a team that was 71-69 with just 5.0% Playoff Odds into one that’s on the verge of cinching the NL’s second Wild Card spot, suddenly giving the Cardinals a look of invincibility. “With 16 Straight Wins, the St. Louis Cardinals May Never Lose Again,” reads one headline. “Cardinals Look Unstoppable Right Now,” reads another.
For as unbeatable as the Cardinals appear right now, the history of late-season winning streaks tells us that while this run may certainly help the team secure a playoff berth, it doesn’t tell us anything about how they’ll fare in October. Look no further than that aforementioned Cleveland team for a harsh reminder of that lesson. From August 24 to September 15 of the 2017 season, the defending AL champions steamrolled opponents, piling up wins in close games and in blowouts until they’d set an American League record. The team finished with 102 wins, the highest total by the franchise since 1954, and hopes were high that they could secure the title that they’d come so close to winning just the year before. Yet when the postseason rolled around, Cleveland was unceremoniously bounced, losing a tight five-game series to the Yankees.
The story was similar for the team whose AL record they broke. The 2002 A’s won 20 straight games from August 13 to September 6 and finished with 103 wins, the franchise’s highest total since 1988. Yet they too were defeated in a five-game Division Series, losing to the Twins.
In fact, no team that’s run off a late-season streak — starting in August or September — of more than 11 wins has even reached the World Series during the division play era (1969 onward):
