Watch: Marlins' Kyle Stowers delivers walk-off grand slam vs. Athletics

By Andrew Wright | Last updated May 3, 2025 7:36 PM ET

Entering Saturday's game against the Miami Marlins, Athletics closer Mason Miller was a perfect 10-for-10 in save opportunities.

Miami had plans to ruin that perfect streak and it did just that, highlighted by a walk-off grand slam from right fielder Kyle Stowers.

The grand slam for Stowers was his second home run of the game. It capped off the five-run ninth inning for Miami.

As previously mentioned, the blown save for Miller was his first of the season and it inflated his ERA to 4.97 for the season.

Stowers' walk-off grand slam was the sixth in franchise history and first since April 18, 2014, when Giancarlo Stanton did it against the Seattle Mariners.

OF Kyle Stowers today hit the 6th walk-off grand slam in Franchise history. The others are:

Bobby Bonilla - Sept. 16, 1997 vs. COL
Dan Uggla - June 11, 2008 vs. PHI
Giancarlo Stanton - May 13, 2012 vs. NYM
Jeff Mathis - June 30, 2013 vs. SD
Giancarlo Stanton - April 18, 2014 vs.…

While it won't be the start of a magical postseason run for the Marlins, it will certainly be a fun moment for Stowers to always look back on.
