Marlins complete season-opening sweep of Rockies on Owen Caissie walk-off homer after early deficit

Miami opens 2026 at 3-0 after late two-run shot seals 4-3 win

The Miami Marlins completed a three-game sweep of the Colorado Rockies on Sunday, March 29, 2026, finishing the season-opening series with a 4-3 walk-off victory at loanDepot park. Outfielder Owen Caissie ended the game with a two-run home run in the bottom of the ninth, turning a one-run deficit into Miami’s third straight win to start the year.

The finale followed a pattern that defined the set: tight margins, limited offensive separation and decisive late at-bats. Miami entered the ninth trailing 3-2 despite holding Colorado scoreless after the first inning. Caissie’s homer, measured at 394 feet to right-center, brought home Ronny Sanoja and ended the game immediately.

How the game swung: three-run opening, then a long stall

Colorado jumped ahead quickly in the first inning. Jordan Beck’s two-out double plated three runs, aided by a throwing error from shortstop Otto Lopez that allowed Beck to reach third. Miami responded right away when Lopez doubled in the bottom of the first, scoring Jakob Marsee to cut the deficit to 3-1.

The Marlins inched closer in the second on a sacrifice fly by Austin Slater that scored Xavier Edwards. From there, both pitching staffs kept the game static until the final swing. Miami finished with eight hits and Colorado with six; neither team recorded an extra-base hit after the early innings until the ninth-inning homer.

Pitching takeaway: Miami’s bullpen stabilized after a short start

Max Meyer started for Miami and was followed by a bullpen that held Colorado to three runs total, with the Rockies scoring all three in the first. The win was credited to reliever Matt Petersen, who worked a scoreless ninth. Colorado’s loss went to Victor Vodnik, who allowed two runs in the ninth after Miami managed only two runs through eight innings.

• Colorado scored three times in the first inning and did not score again.
• Miami scored in the first, second and ninth, with no runs from the third through eighth.
• Defensive execution factored into the early scoring, as Miami committed two errors in the game.

Series snapshot: one-run games and late pressure

All three games were decided by one run. Miami won the opener 2-1 on March 27, followed with a 4-3 victory on March 28, then closed the sweep with Sunday’s 4-3 walk-off. The consistent theme was Miami’s ability to stay within striking distance and convert late opportunities, while Colorado failed to protect narrow leads in consecutive games.

Final (March 29): Marlins 4, Rockies 3 — Walk-off, two-run home run in the bottom of the ninth.

Miami’s 3-0 start places the club atop the National League East in the season’s opening weekend, while Colorado left Miami still searching for its first win of 2026.
