Rafael Marchán is heading back home with a lot to prove.
The 27-year-old catcher has joined Tiburones de La Guaira in the Venezuelan Winter League, a move that puts him in position to try to rebuild some value after a season that left him squarely on the roster bubble. Marchán arrives in Venezuela after a career that has long been defined by the same split judgment: elite glove, questionable bat.
That reputation started early. He was praised throughout the minors as a defensive anchor behind the plate, the kind of catcher teams could trust for years if the offense ever came around.
Then COVID-19 wiped out much of the Phillies’ roster in 2020, and Philadelphia pushed the 21-year-old Marchán straight from High-A to the majors. He made the most memorable offensive statement of that surprise call-up by launching his first professional home run at Citizens Bank Park.
There was another small burst of optimism in 2024, when Marchán filled in for the injured J.T. Realmuto for about a month. He hit .294 with an .894 OPS, enough to make people wonder if the bat had finally started to catch up.
But the larger body of work still hangs over him. Marchán owns a .202 career batting average and a sub-.600 OPS, and after more than three years of service time, he finds himself fighting against the clock again.
Tiburones de La Guaira are not a quiet landing spot. Fernando Tatis Sr. manages the club, which also features former MLB players Yangervis Solarte and Alcides Escobar, along with Jurickson Profar, who was suspended for PEDs.
Marchán was reported in Venezuela ahead of winter ball, and the stakes around this stint are obvious. He is viewed as a non-tender candidate this offseason, and a strong showing could help him shake off what the source describes as a lost season.
Tiburones opened their season Monday night at Estadio José Bernardo Pérez in Valencia and came away with a 10-6 win over defending champions Navegantes del Magallanes. Former Phillie Símon Muzziotti delivered the big blow, lining a bases-clearing double in the third inning to put Tiburones in front for good.
Marchán went 0-for-3 with a walk in that game while catching Ricardo Pinto, another former Phillie, who lasted only two innings and allowed five runs on seven hits. Tiburones moved to 2-0 on Tuesday night, though Marchán did not appear in that game.
The Phillies’ catching picture could get more complicated from here, especially with the lockout looming ahead of the 2027 season. Realmuto is expected to remain the primary catcher, but the Garrett Stubbs-Marchán tandem was one of the least productive backup groups in baseball in 2026.
Philadelphia catchers finished with the lowest on-base percentage in the majors at .253. The next-worst club, the Angels, sat at .273.
If Marchán does not make a strong impression this winter and then again in spring training - if there is one - the Phillies may have a hard call to make. He is out of minor-league options, which means the club would need to expose him to waivers if he does not make the 26-man roster. The source also notes the team is looking for a Jonah Heim-type player to create some competition for Stubbs and Marchán.

Phillies Just Lost More Catching Depth Than Fans Realized
Payton Henrys time in the Phillies organization has come to an end, with the catcher electing minor league free agency after spending part of 2026 on Philadelphias major league roster without appearing in a game. It was a brief stop, but one that still mattered in a season where teams are always trying to patch together catching depth behind the scenes, especially when the big-league club needs insurance and the system is being tested.
Henrys departure leaves one less experienced option in the organization, and it comes as the Phillies continue sorting through the smaller roster moves that can end up carrying more weight than they first appear. He has big-league experience with the Marlins, but now joins a familiar offseason churn at a position where depth is never just a detail, even if the next move on his path is still to be determined.

Phillies Are Seriously Reworking Kyle Schwarbers Role Next Season
Dave Dombrowski made it clear the Phillies are not treating the end of the season as a tune-up for the status quo. Along with coaching staff changes, the president of baseball operations signaled a new wrinkle for Kyle Schwarber, saying the veteran will get work at first base during Spring Training as the club looks for ways to keep its regulars fresher over the grind of next season.
Schwarber has spent most of his time as Philadelphias designated hitter, so the move would represent a notable change in how the Phillies deploy one of their most recognizable bats. The plan is for him to appear there in roughly 30 games next season, a shift that adds flexibility for the roster while also raising an obvious question about how much the team is willing to stretch his limited experience at the position.

Phillies Defense Just Sent A Brutal Message About This Roster
Defense has become one of the clearest pressure points for this Phillies roster, and the numbers from 2026 made the message hard to miss. Philadelphia finished tied for last in Defensive Runs Saved, sat in the bottom 10 in Outs Above Average and Fielding Run Value, and was one of only three National League clubs without a Gold Glove finalist.
The concern is not tied to one position or one player, either. Trea Turner, Alec Bohm, Bryce Harper and others all showed up on the wrong side of the defensive metrics, which leaves the Phillies staring at a broader roster issue rather than a single cleanup job. For a team built to contend, that kind of all-around decline invites an uncomfortable offseason conversation about how much of the current alignment can stay intact. [Read more 🡒]
