Cardinals 9, Pirates 6: Iván Herrera Walk-Off Slam Ends 10-Inning Thriller at Busch

The lead

May 19, 2026 - St. Louis - The St. Louis Cardinals won their 15th comeback victory of 2026 when Iván Herrera launched a three-run walk-off homer in the 10th for a 9-6 decision over the Pittsburgh Pirates at Busch Stadium, per St. Louis Post-Dispatch and Yahoo Sports.

Herrera's blast was his first career walk-off homer and the seventh extra-inning win for St. Louis this season. Alec Burleson went 2-for-3 with a homer and three runs scored; Nolan Gorman homered twice in the fight—including a two-run shot in the sixth after Pittsburgh had seized the lead.

How the game turned

Rookie JJ Wetherholt homered in the third as part of a 3-0 Cardinals start. The Pirates answered with four runs in the fifth to lead 4-3, then tied the game 6-6 in the ninth before Herrera ended it in the 10th.

Matthew Liberatore struck out a career-high nine for St. Louis in a night defined more by rallies than length work. Pittsburgh's bullpen held until the final swing.

Pitching and matchup notes

The Cardinals improved to 28-19 while Pittsburgh absorbed another late collapse in a game that flipped leads three times after the fifth.

AthX Engine credited Burleson with 10 hitting FP and graded St. Louis at 15 team FP—tied for fourth on the Tuesday board despite the extra innings.

Bats that changed the board

Burleson's solo homer in the eighth restored a 6-4 edge before Pittsburgh's ninth-inning answer set up Herrera's walk-off theater. Gorman's multi-homer night supplied the middle-inning punctuation.

AthX Engine fantasy angle

Walk-off homers and multi-run comebacks concentrate hitting FP on catchers and corner bats even when the starter's K total was the steadying force—AthX Engine values that volatility separately from dynamic pricing.

What comes next

St. Louis leans on late-inning muscle in a tight NL Central picture; Pittsburgh hunts cleaner ninth-inning execution after another Busch heartbreak.
