Nick Castellanos, Baggage and All, Has What Padres Need

To say that outfielder Nick Castellanos will not be a member of the Philadelphia Phillies in 2026 isn't any kind of speculation. President of baseball operations Dave Dombrowski already indicated as much early this winter and has reiterated it within the last handful of days. Whether it's by a trade — wherein the team would have to eat a decent chunk of the $20 million owed to him in 2026 — or an outright release as a desperate measure, Castellanos will be playing his home games somewhere other than Philadelphia this season. 

Should it be San Diego that steps in as the next destination for the veteran hitter? 

After a pair of seasons where he combined for 52 home runs, Castellanos is coming off some of the worst work of his career in 2025. His slash line read just .250/.294/.400, with a 90 wRC+ and even worse defensive metrics (-12 Outs Above Average). The compounding of meager production at the plate and serving as a non-viable presence on the outfield grass led to a career-worst -0.6 fWAR. 

Now, a year ahead of free agency, Castellanos is presumed to be finding a change of scenery in the coming weeks. That comes as no surprise on the merits of the performance alone, but also the presence of numerous reports that Castellanos took umbrage with manager Rob Thomson's use of him in 2025. When one considers the myriad issues the Phillies have had with their players in recent months (remember the Bryce Harper "not elite" drama?), it becomes a bit more difficult to take Castellanos' struggles completely at face value. 

If we expand his body of work to his entire career, Castellanos is a .272 hitter with decent power (.193 ISO) who also doesn't walk much (6.2 BB%). His career wRC+ sits at 109. He's prone to bouts of streakiness, but compensates well enough in the high points to make up for the low points and lack of on-base percentage. He could also be exactly what the San Diego Padres seek at this stage of the winter.

Isolating Castellanos' output to pitcher handedness, he's gone for a 127 wRC+ and .215 ISO against lefties. Against right-handed pitching, meanwhile, those numbers sit at 103 and .185, respectively. In short, the right-handed swinger holds up well against pitchers of the same handedness but finds his real value when he's matched up against the opposite. An opposite which the Padres just so happen to need in their lineup. 

San Diego ranked 17th in the league in wRC+ against southpaws in 2025 (96) while sitting closer to the back of the rankings on the power side (their .130 ISO ranked 23rd). While they didn't strike out against left-handed arms, they did make the lowest rate of quality contact against pitchers from that side, as well. For his money, Castellanos posted a hard-hit rate roughly 12 points higher in 2025 than the team's collective against left-handers. From a skill set standpoint, he certainly looks like the kind of player in which A.J. Preller should have interest. 

The issue lies in the logistics. 

At $20 million, it's difficult to see the Padres ponying up the cash to pay Castellanos given their current payroll constraints. While the expectation is that the Phillies will eat significant money, the unknown of how much money makes it difficult to project how realistic such a deal is. The return for a player that an organization is openly set on dealing isn't a concern so much as the finances. So in this case, the Padres' lack of depth on the farm isn't the issue. It's purely the money. 

Then, there's the roster fit. The Padres could have some combination of Gavin Sheets, Luis Campusano, and Sung Mun Song rotating as part of the bench, perhaps with Bryce Johnson filling out the foursome. Sheets can play first and outfield. Campusano can fill in behind the plate and at first. Song may get some outfield time beyond his utility infielder status. Johnson can competently play all three outfield spots. Considering the Padres already have a full starting outfield and the likes of Sheets and Campusano to rotate through first base and designated hitter, are they willing to deploy limited resources for a player that might end up representing something of a redundancy (even if said redundancy possesses the upside to be better than what is already present)? 

Even with the reasons to say "no," it's hard for the Padres to justify not at least exploring a deal to acquire Nick Castellanos. Especially if it reaches a point where the Phillies are eating a majority of the money or outright release him before the season starts. Their need for secondary offense and right-handed hitting is no secret. They're not in a position to turn away a good hitter, regardless of the contextual baggage with which they come.
