Marlins Rookie Hits Walk-Off Homer in Teal Jersey Debut

A 23-year-old rookie who'd never seen the original Marlins teal jerseys just became part of their legend.

Owen Caissie launched a walk-off two-run homer Sunday to give Miami a 4-3 win over the Colorado Rockies, completing a sweep and pushing the Marlins to 3-0 for just the third time in franchise history. The timing made it even sweeter: Miami was debuting their new all-teal throwback uniforms, honoring a color that defined the team's early glory days.

"I kind of blacked out," Caissie said after his first career walk-off hit. "I don't really know what happened."

The moment almost didn't come. Caissie had rolled his ankle in his previous at-bat and was hobbling down the first base line. But when teammate Javier Sanoja doubled to keep the ninth inning alive, Caissie got his redemption shot against Rockies pitcher Victor Vodnik.

He adjusted his batting stance to catch up to the fastball and sent a 93.8 mph changeup soaring over the right field wall. Caissie became the first Marlin since 2017 to have his first home run with the team be a walk-off shot.

The Canadian outfielder, acquired in a trade this offseason, has started his Miami career with a scorching 5-for-10 performance, including two doubles and four RBIs. Only nine other players in Marlins history have collected three extra-base hits in their first three games with the club.

Why This Inspires

The Marlins weren't supposed to be here. This young, inexperienced team entered the season as underdogs with low expectations. Yet they've now won 57 of their last 99 games dating back to last June, a .576 winning percentage that ranks sixth best in baseball during that stretch.

They're ahead of the two-time defending World Series champion Dodgers. They're three games over .500 for the first time since clinching a playoff spot in 2023. And they're doing it with rookies like Caissie writing storybook moments in uniforms that honor the 1997 team that shocked the world and won it all.

Manager Clayton McCullough had predicted before the ninth inning that Griffin Conine, son of Marlins legend Jeff Conine, would deliver the decisive hit. Instead, it was the newcomer who didn't even know the history of teal until last month.

"The great thing about baseball is so much of it is rooted in history," McCullough said. "For this organization, this teal uniform is a big part of that history."

Now Caissie is part of that history too, proving that sometimes the best stories are written by those who haven't learned the script yet.
