FORT MYERS, Fla. — Triston Casas can occasionally be a man of mystery.

The Red Sox first baseman left many confused this offseason when he wrote on Instagram about how he was going “to try to be as transparent as possible,” even though the post itself wasn’t transparent. It was extremely ambiguous.

On Nov. 4, Casas posted a photo of himself watching the flight of a ball off his bat to left field at Fenway Park. Steely Dan’s song Deacon Blues played in the background. He wrote, “If we’re gonna have any chance at something decent it’s stuff like this that needs to be addressed , I’m going to try to be as transparent as possible… within reason . No delusion , just normalizing the tough conversation.”

It received 4,856 shares, 23,600 likes and 697 comments. The New York Post even published a story about it, questioning the meaning behind the “cryptic message.”

So what did the message mean? Casas said it was a message directed at someone specific but he wouldn’t say directly who.

“All my Instagram captions, I’m talking to one person,” Casas said Thursday at JetBlue Park. “That’s just something that I’m thinking that I’m not saying to them, that I put it on the caption. So they don’t even mean anything really relatively to my life.”

That’s as far as Casas would go.

“I can’t tell you the person, but I can tell you that it’s to a person,” Casas said. “They know what the message is. And I think that they just go great with the pictures that I put them with.”

Casas’ Instagram posts do each read like messages to an individual person. For example, he wrote June 4, 2024, “From now until then, I promise to love you, through the good and the bad. I’ll put no one else above you and all that I ask from you in return is to let me in, give ‘us’ an honest chance. Include me in any all of your future plans and you’ll see I was meant for you, and you were meant for me. Soulmates for all of eternity.”

He wrote March 20, 2025, “Is it that hard to listen to more problems than you bring? Okay you had your one day but that was like a week ago . can we go back to how things were? I want to love you as much as karma. Sure time stops, let the people watch , it was only ever us anyway.”

Casas suffered a season-ending patellar tendon injury May 2, 2025 that required surgery. The Red Sox don’t know yet whether he’ll be ready for the start of the 2026 season.

The 26-year-old struggled at the plate before the injury, going 18-for-99 (.182) in 29 games. Casas has struggled to stay healthy each of the past two seasons, prompting the Red Sox to trade for first baseman Willson Contreras this past offseason.

Casas said in January that he wasn’t surprised the Red Sox traded for a first baseman.

“The first baseman position for this team has lacked over the last couple years, the production from that spot,” he said Jan. 10. “As of right now, the way that is is, he’s a better player than me and has been for his entire career. To upgrade at a position that has been deficient for the last two years is exactly what the team needed. Hopefully, I can come back to the player I was a couple years ago and know what I can be and contribute to the team whatever fashion and at whatever position they see fit for me.”
