MIAMI — What a 72 hours it has been for rookie outfielder Owen Caissie in a Miami Marlins uniform.
Manager Clayton McCullough inserted Caissie into the Opening Day lineup Friday against the Colorado Rockies at loanDepot park after first baseman Christopher Morel was scratched late due to a left oblique strain.
He went 1-for-4 and drove in a run in the Marlins’ 2-1 win.
Caissie, starting in right field on Saturday, delivered a go-ahead RBI single into shallow center in the eighth, securing a 4–3 victory for the Marlins.
Then, on a day when the Marlins debuted their new teal jerseys and throwback caps Sunday, the 23-year-old found himself in the biggest moment of his young Major League career.
Facing Rockies closer Victor Vodnik, with Javier Sanoja on second base and two outs in the ninth inning, Caissie drove a Vodnik changeup 394 feet into the Colorado bullpen in right field for a walk-off two-run home run, capping a strong start to his Marlins career.
He replaced Austin Slater as a pinch-hitter an inning earlier.
“I kind of blacked out,” Caissie said to reporters after the game Sunday. “I don’t really know. I don’t know if kids imagine that, but it’s awesome. To get the ‘W’ and get the sweep was great.”

That’s the kind of person Caissie is: he remains humble, regardless of the outcome.
Many people forget, but Caissie wasn’t even with the organization during the first year of the Clayton McCullough era.
The Canadian, from Burlington, Ontario, was the headliner in the January trade that sent former Marlins right-handed starter Edward Cabrera to the Chicago Cubs.
In three games with the club, Caissie leads the team in hits (5), RBIs (4) and batting average (.500) ― a big reason the Marlins are off to their best start in 17 seasons and the only team in the National League East still undefeated.
Caissie is well aware, too, that there are still 159 games left to play.
“You kind of wish for moments like this, and I just want to keep putting good swings on the ball,” Caissie said. “I know that’s not always going to be like this, but if I continue to stay with my plan, I know good things are going to happen.”
