Could these 9 prospects the Phillies traded help them in 2027?

In their still-futile quest for a World Series title, the Philadelphia Phillies have traded away a vast haul of prospects at the deadline and over the offseason.  For the most part, they’ve avoided moving their top-100 guys, yet they’ve still sold plenty of future talent to pay present dues.

Since 2023, we count nine important prospects included in needle-moving (or often not) deals. Here’s how each player is performing for their new club today.

Ramon Marquez

In the biggest deal of the 2026 trade deadline, the Phillies sent Ramon Marquez to the San Francisco Giants in exchange for Luis Arraez and Caleb Killian. While the club surely regrets losing a top-100 prospect in a deal for Arraez, who missed the postseason, the jury is still out on Killian.

Marquez currently ranks as MLB’s No. 94 prospect after pitching in only two games for the Giants’ High-A Eugene Emeralds. He missed the last month of the season with an injury and gave up six runs in 10 innings, but struck out 12 and walked only one. The Giants are high on the 21-year-old righty. He should factor into their rotation by 2028.

Luke Gabrysh

In the only other Major League move from this year’s deadline, the Phillies shipped local kid Luke Gabrysh to the New York Mets in exchange for Brooks Raley. At best, Philadelphia hopes for a wash; Raley was a disaster in Phillies pinstripes.

Gabrysh started six games for Brooklyn and Binghamton, High-A and Double-A, respectively, but struggled with the long ball at the latter. He posted a 6.88 ERA in Binghamton and likely projects as a back-end starter or swingman. Perhaps he could be an effective reliever one day.

Hendry Mendez

Sent to the Minnesota Twins in the deal that brought Harrison Bader to Philly, Mendez ranks as the Twins’ No. 8 prospect. He could be ready to make his Major League debut next year, after slashing .281/.374/.430 with 12 home runs across Double- and Triple-A. He may still be a defensive liability, but at just 22, he still has plenty of time to develop.

Eduardo Tait

You have got to give up good players to get good players, and Tait might be the best prospect the Phillies have given up on in this list. Shipped to Minnesota in the deal that brought Jhoan Duran to Philadelphia, Tait could have solved the future catcher problem.

In his age-19 season, Tait hit 22 home runs and slashed a paltry .221/.281/.418, striking out 119 times at High-A Cedar Rapids. He really lacks plate discipline, but given his youth, the sky is the limit for Tait. He profiles as a future starting catcher.

Mick Abel

Also included in the Duran deal, 2026 should have been Abel's first full year in the big leagues. Instead, he spent much of the year sidelined after undergoing arthroscopic surgery on his elbow. He may miss time in 2027, too.

Either way, Abel’s 20.1 IP in the big leagues was encouraging this year. He allowed only nine runs and struck out 23. He still struggles with command, though; he walked 10 batters in that small sample.

Starlyn Caba

Caba headlined the deal that sent the Phillies to Jesús Luzardo. He ranks as the Marlins' No. 7 prospect after a season slashing .236/.389/.378 at High-A. What really stands out, though, is his defense. Think Johan Rojas of the infield.

Caba is still 20, so he has plenty of time to develop, but with seven home runs, 21 stolen bases, and 71 walks in 373 plate appearances last year, he's been a promising development for the Marlins, though perhaps not as much as Luzardo has been for the Phillies. 

William Bergolla

Bergolla was once a can’t-miss blue-chip prospect for the Phillies. Signed out of Venezuela for $2.05 million, his stock had fallen so far by 2024 that the Phillies traded him for then-reclamation project Tanner Banks.

Bergolla played only 11 games this year after an April injury sidelined him for the rest of the season, but in those 11 games he slashed .444/.524/.556, very encouraging. He has an excellent hit tool and 20-grade power. Perhaps Bergolla can follow the Chandler Simpson model. He’s Rule 5 Draft-eligible this off-season after debuting in the minors at 17, but you’d have to imagine the Chicago White Sox would protect him.

George Klassen

Klassen made his anticipated MLB debut this year after the Phillies traded him to acquire Carlos Estevez at the 2024 deadline. Though he posted a 3.67 ERA in six starts, he walked almost as many batters as he struck out: 21 free passes to 24 Ks. Klassen may be better suited to the bullpen if he continues to struggle with command.

Hao Yu Lee

The Phillies could really use Hao-Yu Lee right now. The right-handed 23-year-old was sent to the Detroit Tigers at the 2023 deadline in exchange for Michael Lorenzen and had an excellent rookie season at second and third base.

Lee popped 10 home runs and slashed .264/.322/.424 in 364 plate appearances. He’ll certainly receive down-ballot Rookie of the Year votes. If he were a better defender, those votes would be higher, but Lee was 1st percentile in OAA. Nevertheless, any Major League team would love to have him on their bench, even if he couldn’t crack the starting lineup.
