With former All-Star outfielder Nick Castellanos’ tenure clearly done in Philadelphia, could he solve the Padres’ need for slug?

With the Phillies aiming for a last-dance push to the postseason with an aging core, Nick Castellanos does not appear to be in their plans for 2026.

Phillies president of baseball operations Dave Dombrowski has been on the record saying so; When he was asked about pursuing a change of scenery for Castellanos, Dombrowski’s response was clear: “Yes, we do. We still plan on doing that”. 

Castellanos is not the same player he was in his prime, back when he was setting the NL Central on fire.

Since signing with the Phillies before the 2022 season, his production has been a mixed bag.

In 602 games since signing the contract, Castellanos has slashed .260/.306/.426 for a .732 OPS and an OPS+ of exactly 100. His counting stats include 82 home runs, 326 RBI, and 28 stolen bases. On a percentile basis, Castellanos has a 23.7% strikeout rate and 5.6% walk rate over the past four seasons.

The strikeout rate is around the league average, but his walk rate is below the MLB average from 2025 at 8.4%. Production-wise, Castellanos has been an average player, but has only accrued 1.3 bWAR (or 0.7 fWAR depending on your choice of WAR model). This can be attributed to his defense, which in right field has been… let’s call it an adventure.

Though Castellanos has a few highlight-reel plays (his sliding catch in the World Series comes to mind), defensive metrics paint him as one of the least valuable outfielders in baseball.

Among all qualified right fielders from 2022 to 2025, Castellanos’ -45 (yes, that says negative 45) run value ranks as 120th out of 120 qualified outfielders. For reference, the 119th-ranked right fielder in this span is Juan Soto at -30 run value. 

Despite his defensive shortcomings, Castellanos still has value for a team looking to add a bat.

Is he worth $20 million? No, but the idea of Philadelphia retaining some salary still exists, and we’ll revisit that later.

Castellanos’ offensive profile has seen some decay since the heights of his Reds tenure. However, there are signs that there remains a productive hitter. Castellanos does not have an overly high ground-ball rate, sitting at 38.2% in 2025. 57.7% of his batted balls in 2025 were either fly balls or line drives, the sorts of contact that have the highest chance of leading to base hits. He also registered a 39% launch-angle sweet spot percentage, which ranked him in the 88th percentile among qualified batters.

While he has seen some of his offensive tools take steps back in recent seasons, he has continuously excelled at hitting the ball at the ideal angles. This season’s 40.7% pull rate was the second-highest of his career as well. Another notable tidbit about Castellanos’ swing is that he can keep the barrel in the zone quite well, allowing balls inside to result in gap hits to the opposite field. 

Now, defensively, Castellanos would not be playing much, if any, right field for the Padres in an ideal world. Left field would likely be off the table as well, with Ramon Laureano’s plus arm out there. Should San Diego acquire Castellanos, as MLB insider Ken Rosenthal floated the possibility of, it would be to play first base. Now, the Padres did come close to bringing in Nolan Arenado to play first base, but those pursuits did not pan out. Would Castellanos be open to playing first base? According to the man himself, it is something that he would be open to should a team need him to do that.

So how would Castellanos slot into the Padres’ lineup? Castellanos would likely slot into the six or seven spot in the lineup to provide some thump in the lower half of the lineup alongside Gavin Sheets. Sheets and Castellanos could also split time at first base and DH while Castellanos gets acclimated to the position during spring training and the early parts of the season. If Castellanos can continue to square up the baseball, he would be a solid complementary piece to a lineup with players who have shown strong on-base tendencies.

Then comes the price tag. Castellanos is making $20 million for 2026 but has no club option remaining or any sort of opt-out that would require additional financial commitment.

There is simply no chance that the Padres take on the entirety of that contract.

However, if Philadelphia can pay down 75% of the contract, negotiations may be able to pick up some steam. Castellanos at a $5 million price tag is much more palatable for the Padres and the state of their payroll. It likely would not take a huge prospect haul to land Castellanos, and we can use the Arenado trade as a blueprint.

Arizona parted with 2025 8th-round pick Jack Martinez in the trade to acquire Arenado at a $5.5 million AAV over two seasons. With Castellanos being a one-year rental in this hypothetical scenario, one year at $5 million would not require a top 30 prospect. The Phillies lack relief depth in the upper minors, relievers with minor league options. Therefore, the Padres could part with one or two minor league bullpen arms in a trade. The likes of Andrew Moore, Cole Paplham, Andrew Dalquist, or Fernando Sanchez fit the bill, and another low-minors prospect could be added in as a sort of lottery ticket in this trade. 

The Padres are waiting for the right kind of opportunity to materialize to bring in major league depth. Nick Castellanos, while not the same player he was a few years ago, could be an inexpensive addition to lengthen the lineup in their quest to return to the playoffs.
