In the first round of the 2026 MLB postseason, the Chicago White Sox faced off against the Houston Astros in Houston in the AL Wild Card.
They won 6-3, and there were a few reasons for the victory, one of which was thanks to Colson Montgomery 's home run to straightaway center field. That was a slump-breaking homer as well, making it all the more special for Montgomery.
That slump-breaking HR actually made some MLB history. According to Jayson Stark of The Athletic , Montgomery's slump entering the postseason was the worst by any player who later went on to his a home run in that same postseason run.
Colson Montgomery made MLB history with an all-time slump-breaking HR
"What's the record for worst season-ending slump by a player who then hit a home run in that postseason?" Stark questioned. ",,, And who was in first place? Yes, Colson Montgomery ... because of course, he was."
Entering the postseason, Montgomery went a horrible 4-for-65 with 36 strikeouts, which helped him set the all-time single-season strikeout record.
But in his first postseason game, Montgomery hit a homer to make it 4-0, which wound up being the game-winning run in the 6-3 victory.

Stark's question was answered by STATS Performed Sam Hovland, who figured out that Pat Sheridan in 1987, who went 5-for-65 before the postseason, was the second-worst slump in MLB history before hitting a homer in the playoffs.
Third place was a tie between pitchers Dave McNally in 1969 and Mike Cuellar in 1970. But first place belongs solely to Montgomery.
This is the kind of MLB history that might never be broken again, as it's such an obscure statistic. Still, for a player to go 4-for-65 leading right up to the postseason, and then hit a home run, is quite an impressive feat.
Montgomery will look to stay hot in Game 2 against the Astros and help the White Sox secure a series win that'll allow them to host at least one home playoff game this year.
