The Miami Marlins completed a three-game sweep of the Colorado Rockies to open the 2026 MLB season, capped by a dramatic walk-off home run from rookie outfielder Owen Caissie in the bottom of the 9th inning of the series finale.

Why it matters

The Marlins' strong start is an encouraging sign for the team's young core, which is looking to build on last season's surprise playoff appearance. Caissie's heroics also showcase the team's promising crop of up-and-coming talent.

The details

With the game tied 3-3 in the bottom of the 9th, Caissie stepped up to the plate against Rockies closer Daniel Bard and launched a towering shot over the left field wall to give the Marlins a 4-3 victory. The 23-year-old Caissie, who made his MLB debut last September, is expected to be an everyday starter for Miami this season.
