Rintaro Sasaki’s path to Miami has already been unusual, and the next step comes with a new language goal attached.
The Japanese-born first baseman, drafted by the Marlins in the eighth round this month, said Thursday that he plans to keep pushing his game forward while also working on Spanish as he begins his pro career. Sasaki signed for $210,200, according to MLB Pipeline’s Jonathan Mayo, after announcing on Instagram earlier this week that he intended to join the organization.
“I’m actually grateful to play here,” Sasaki said at his introductory press conference. “[Suzuki's] not playing right now, but I actually care for and really respect him for playing here. And now I’m here, I’m so glad.”
That connection to Ichiro Suzuki runs deep for Sasaki, who grew up in Hanamaki, Iwate Prefecture, watching Suzuki from afar as the Hall of Famer made history in a Marlins uniform and collected his 3,000th Major League hit in Miami. Now Sasaki gets his own shot in the same city.
The decision to sign with the Marlins came after he weighed several paths. He could have returned to Stanford University, or he could have signed with the Fukuoka SoftBank Hawks of Nippon Professional Baseball, who won exclusive negotiating rights over the Yokohama DeNA BayStars after both clubs selected him in the NPB first round last October.
Sasaki didn’t hide what drove the choice.
“Anywhere is great options,” Sasaki said. “...
But my goal is, my dream is always going to be how I'm going to make the big leagues as soon as possible. So, that's a big reason for choosing [this way].
Miami is giving me a great opportunity for me. So excited, too, and so grateful.
That's a big reason I choose.”
The Marlins have already started the onboarding process at their 2026 Draft camp at loanDepot park, where Sasaki and the rest of the class are beginning the transition toward their Minor League assignments. He said the organization made a strong early impression.
“They actually made me feel so very welcome to come to Miami,” Sasaki said. “They also told me about kind of development plannings also, too.
So, that's actually feeling great for me. I actually kind of create, made the vision for playing here.
That's actually a big reason for deciding here. Want to be part of the Marlins' players, try to win, try to help the teams.
That's always going to be a reason.
“It’s going to be hard work. ... Keep doing what you do.
Try to improve. Try to get better for everything.
Even hitting stuff, defense stuff, baserunning, everything, physical.”
Sasaki’s bat has already shown real growth. After the early spotlight that came with his move to the United States, he hit seven homers and posted a .790 OPS in 2025.
He took another step in 2026, finishing with 16 homers and a .952 OPS for Stanford, while drawing 45 walks against 50 strikeouts. His raw power has also shown up in a big way, including a 458-foot homer and some of the highest exit velocities at June’s Draft Combine, where his max was 115.4 mph.
And beyond the bat, Sasaki is thinking about fitting in off the field too.
“Maybe trying to speak Spanish, studying,” Sasaki said. “I think that's the next goal. I'm not like a native speaker here for English, so English first, and then coming to Spanish at the same time.”

Marlins Face A Tough Heriberto Hernndez Deadline Decision
Heriberto Hernndez has given the Marlins something useful to think about over the last stretch, even as the losses keep piling up around him. Since his May 7 recall, the outfielder has been one of the few bright spots in a lineup that still has plenty of holes, and his recent surge has only sharpened the question of whether Miami should treat him as part of the next wave or as one of the clearer chips it can move before the deadline.
The appeal for other clubs is obvious enough: Hernndez is still inexpensive, not yet arbitration-eligible and under control for years to come, which makes him more than a rental-type target. Miami also has to weigh its own internal picture, with a Triple-A bat waiting in the wings and a front office that has to decide whether Hernndezs value is higher in the standings, in the system or in a trade return that could help address more than one need at once.

Former Marlins Arm Faces Brutal New Setback With Braves
Elieser Hernandezs latest stop with the Braves got off to a rough start, and it was over almost as quickly as it began. The former Marlins right-hander had signed a minor league deal with Atlanta last offseason, then worked his way back to the majors after spending time in South Koreas KBO and returning to MLB in 2024.
Atlanta designated Hernandez for assignment after his first game with the club and brought up left-hander Connor Thomas from Triple-A Gwinnett in the corresponding move. For a pitcher trying to reestablish himself after a long and winding path back, it was another harsh reminder of how thin the margin can be once a team starts shuffling the back end of its staff.

Mariners Suddenly Face A Stunning Luis Castillo Deadline Decision
Seattles deadline math is starting to get complicated, and Luis Castillo has become one of the names sitting right in the middle of it. The Mariners are looking for ways to shore up both the bullpen and the offense, which is why any discussion around a potential Castillo move carries real weight. Even with his contract control and track record, the right-handers current form has made him part of a broader conversation about how aggressive Seattle wants to be before the deadline.
For Miami, the idea is intriguing because the Marlins have pushed themselves into the NL East race and could be tempted to add a proven starter if the market breaks their way. A deal like that would not just be about Castillos name value, either, since the return could shape what Seattle does next and what kind of help it can land in the final days before the deadline. The uncertainty around the package is part of what makes this one worth watching, because the Mariners may be weighing a major rotation decision against the chance to fill multiple needs at once.
