Kody Clemens delivered a walk-off grand slam in the ninth inning, erasing a three-run deficit and completing a 4-3 comeback. His 19th home run of the season accounted for every run scored by his club and ended the series with a dramatic victory.

What happened

Clemens' club entered the bottom of the ninth trailing 3-0 and needing a major swing to extend the game. Clemens supplied exactly that, hitting a grand slam that immediately transformed the deficit into a one-run win.

The blast brought home all four runs on one swing and ended the game without another plate appearance. It was Clemens' 19th homer of the season and the decisive moment in a game his club had trailed by three runs entering its final turn at bat.

Why it matters

MLB classified the hit as the 34th ultimate grand slam on record. An ultimate grand slam is a walk-off slam hit when a team enters its final at-bat trailing by three runs, making Clemens' homer both the comeback and the game-ending blow.

The result also clinched a 2-1 series victory. Instead of closing the series with a loss, Clemens' club overturned the game in a single swing and secured the deciding contest.

By the numbers

The comeback began with a 3-0 deficit and ended with a 4-3 final score. Clemens accounted for all four runs, while the grand slam raised his season home run total to 19.

The win brought his club to 55-55, returning it to the .500 mark. It also completed a two-win series and added Clemens' homer to a select group of 34 ultimate grand slams recognized by MLB.

What to watch next

Clemens' club opens a road series Friday with a chance to move above .500. The schedule now shifts away from home after a series-clinching finish built around the most consequential swing of Clemens' season.

The immediate question is whether the momentum from the ninth-inning comeback carries into the road opener. At 55-55, every result will affect whether the club can remain at or climb beyond the break-even point.
