The Marlins are showing interest in Patrick Sandoval, and that makes plenty of sense if you look at the profile they’re betting on.
Miami has a clear appetite for left-handed pitching, and Sandoval fits the kind of arm the club seems willing to take a swing on. Fish On First learned the Marlins are interested in him, with The Athletic and MLB.com also connecting the lefty to other teams.
As one NL executive told MLB.com insider Mark Feinsand, “Lots of teams have wanted him for a while,” one NL executive told MLB.com insider Mark Feinsand. “His fastball plays.
Everybody thinks they can fix the rest.”
Sandoval, 30, spent 2026 working back from Tommy John surgery and didn’t make his first start until July 9. He finished with a 5.12 ERA, 3.77 FIP, 9.34 K/9 and 4.09 BB/9 in 15 appearances, 13 of them starts, for the Boston Red Sox.
The stuff still gave teams something to dream on. His changeup was easily his best pitch, posting a plus-5 run value with a 39.7% whiff rate and a 29.4% PutAway rate.
Everything else was a step behind. His four-seam fastball sat at 93.4 mph, but opponents slugged .589 against it.
His slider had a .300 batting average against and a .420 slug, though it still generated a 28.0% whiff rate. He also mixes in a sinker, sweeper and curveball.
That slider is the pitch that could change the whole conversation. In his best season, 2022, Sandoval leaned much harder on it, and it was missing bats and keeping hitters from doing damage. If he can get that version of the slider back, it could become his PutAway pitch and ease the pressure on the changeup and four-seam combination.
A Marlins deal would also come with some built-in fit. The organization has pushed more of its starters toward using a sweeper, and even Sandy Alcantara added one.
There’s also a path for Sandoval’s sinker usage to climb while the four-seam usage drops. Eury Pérez added a sinker during the season and used it well alongside his other pitches, and Sandoval already has that pitch in his mix.
The strikeout rate is another reason he stands out. Even after surgery, Sandoval’s 9.34 K/9 was above league average and his highest mark since 2021, when he was at his peak. If a team can trim the walks, that’s where the upside lives, and that’s exactly why Miami is interested.
The Marlins also have a need for left-handed starting help. In the entire 2026 season, only two lefties made a start for the club: Robby Snelling and Braxton Garrett.
They combined for just three outings before injuries and a trade ended their seasons. Thomas White, who was expected to debut in 2026, missed most of the year with a shoulder sprain.
A veteran lefty while Snelling and White work back toward full strength would fill a real gap.
There’s also familiarity here. Sandoval has worked with Marlins director of pitching Bill Hezel in the Angels organization, where Hezel served as assistant pitching coach in 2022 and pitching strategist in 2023.
Not all of Sandoval’s rough numbers tell the full story. Since 2024, he has a 5.10 ERA, but his 3.82 FIP is much better than league average, which points to some bad luck in the results.
And financially, this is the kind of move Miami can actually make. The bigger question is whether Sandoval buys into the Marlins’ plan, including calling pitches from the dugout and being flexible with his role. At 30, he looks like one of the stronger bounce-back bets on the market.

Marlins Still Have Two Roster Holes Peter Bendix Must Address
Peter Bendix used the General Managers Meetings to sketch out where the Marlins still have work to do, and the picture is fairly clear even with spring still ahead. Miami expects several right-handed starters to report to Spring Training as part of its rotation mix, but the front office is still weighing outside help as it sorts through the rest of the roster and decides how much it wants to lean on internal options.
The club is also keeping tabs on players coming back from injuries, along with prospects in the minors, while scanning the free-agent market and arbitration pool for fits. Two spots remain especially open-ended: a left-handed arm for the bullpen and a backup catcher, with the latter likely to come from a veteran addition if the right opportunity surfaces. [Read more 🡒]
Marlins Just Made A Risky Bet With Their Hitting Coach Move
The Marlins are making a change in the dugout that says plenty about where they think their offense is headed. Miami did not retain Pedro Guerrero after two seasons, even after he helped oversee some offensive gains and player development, and the club has turned the job over to Dillon Lawson as it looks for a new voice to keep the lineup moving forward.
Lawson brings a different kind of resume to the assignment, one that carries both upside and risk. His recent coaching stops with the Yankees and Red Sox ended before their expected finish, and Miami is betting that a fresh start here will be the place where his approach sticks and the offense takes another step.

Marlins Just Added A Familiar Name In A Very Different Role
The Marlins have added a familiar name in a very different capacity, bringing former outfielder Trayce Thompson into their baseball operations department. It is the kind of move that quietly says a lot about where a player is in his career, especially for someone who spent time across five big-league teams and carved out a long enough run to become a recognizable piece around the league.
Thompsons new role gives Miami another voice with recent playing experience in the room, even as the organization continues to shape its front office and support staff. Around the league, clubs are still busy sorting out bullpen moves and executive hires, but for the Marlins this one stands out because it suggests Thompsons next chapter is starting in the game rather than on the field.
