The case for and against trading Sandy Alcantara

In an organization largely devoid of tenured players, Sandy Alcantara is an anomaly. The 2026 season is his ninth season in Miami, making him just the second player to reach that many years as a Marlins big leaguer, joining Marlins Legends Hall of Fame inductee Luis Castillo.

The main reason why Alcantara hasn't changed teams already is the club conveniently inked him to a contract extension right before his 2022 NL Cy Young Award campaign. Now that he's in the midst of the final guaranteed year of that deal, the Marlins find themselves at a crossroads with one of their franchise's greatest hurlers. 

There are several reasons that support trading Alcantara this summer, as there are compelling ones to hold onto him. Here, we consider both sides of the debate. 

Case for Trading

If there is one thing playoff contenders will seek out come deadline time, durable starting pitching would be near the top of that list. Alcantara is the epitome of this archetype. Despite missing all of 2024 due to recovery from Tommy John surgery, Alcantara's 939 innings in the 2020s rank as the 12th-most in MLB. The only scheduled start he has failed to make post-Tommy John was when he went on the paternity list in April 2025 for the birth of his daughter.

Beyond the workhorse mentality, there's the performance on the whole, as Alcantara is one of just 12 pitchers in the decade to throw at least 900 innings and post a sub-4 ERA. Consider it quality volume, if you will. 

Alcantara's previous playoff experience is another feather in his cap. The right-hander made two starts in Miami's surprise 2020 playoff season, posting a 4.26 ERA over 12 ⅔ innings pitched.

Conveniently for the Marlins, there are prospective Alcantara suitors with immensely talented farm systems. The Milwaukee Brewers were ranked No. 1 by ESPN entering 2026. Though they enter Monday fifth in fWAR among starters and fourth in ERA, Milwaukee needs to fill the 157-inning gap left by the void of Quinn Priester, who is set to undergo season-ending thoracic outlet surgery. The Cleveland Guardians have the second-ranked system. They have relied on the same five starters all season thus far, which will not be sustainable considering that three of them have never shouldered a full season's major league workload before.

Alcantara is earning $17.3M this season, but the acquiring team would only be on the hook for about $5.4M of that cost if a trade waits until the August 3 deadline. His $21M club option for 2027 reads as a bargain. Should he flop down the stretch for whatever reason, that option could be bought out for a modest $2M.

Case for Not Trading

Alcantara may be more valuable to the Marlins roster than he would be as a trade chip. Holding steady at 40-38 through their first 78 games played, the Marlins find themselves merely half a game out of an NL Wild Card spot entering Monday. They have shown no signs of slowing down, going a league-best 14-4 in June.

Even with Alcantara in the fold, their starting rotation is thin. The club's top-ranked prospect, Thomas White, is questionable to pitch again this season due to a shoulder injury. Second-ranked Robby Snelling has already been ruled out for the rest of 2026 after undergoing UCL surgery. Eury Pérez is nearing his return from a leg injury, but he was posting career-worst numbers through 12 starts, so expectations for him ought to be tempered accordingly.

Filling out the rotation alongside Alcantara, Pérez and Max Meyer, Miami has resorted to Ryan Gusto and Tyler Phillips, who have posted a combined 5.51 ERA across 32 ⅔ innings pitched in that role.

Alcantara was very much on the trade block in 2025, but stayed put due to reportedly underwhelming offers. Although another year removed from Tommy John, he still has his fair share of red flags that may prevent the Marlins from extracting a massive prospect haul. 

Alcantara's overall results have been underwhelming with a 4.92 ERA over the past two seasons, nearly 50 percent higher than his 3.32 career mark prior to TJ. The decreased effectiveness of his arsenal is undeniable. While still averaging north of 97 mph on his four-seam and sinking fastballs, hitters largely have not been fooled by the former, hitting .316 with a .526 slugging percentage, and registering a minus-3 run value. Teams pay a premium for swing-and-miss stuff, which does not apply to Alcantara even when he's performing well. Among 187 pitchers with at least 50 plate appearances ending on a four-seamer, his 17.8 percent whiff rate ranks 133rd. 

The Marlins bullpen has been a bright spot throughout this season. A key to maintaining that will be providing adequate rest for those relievers. For whatever flaws he has, Alcantara can be trusted to help in that department, as he ranks second in MLB in both total innings pitched and quality starts. He's still a valuable complementary piece of this pitching staff.

If this is indeed farewell, Alcantara's impact on the Miami Marlins cannot be overstated. The lone Cy Young winner in franchise history, only Josh Johnson accrued more pitching bWAR with the club than Alcantara's 21.7. With at least four strikeouts in his next start, he will take sole possession of the franchise's career strikeout record. By FanGraphs' accounting, his on-field production through the years has been worth nearly three times as much as his contract.

The next month and change of Marlins baseball will signal further the direction the ship is sailing in.
