After getting bounced in the NLDS for the second-straight year, the Philadelphia Phillies enter a pivotal offseason, where they will have to make tough decisions regarding multiple veterans, who have been part of their core for the last three-plus seasons.

One of those veterans is right fielder Nick Castellanos, who looks to be on his way out the door after a disappointing 2025 season (.250 with 17 home runs and 72 RBI) at the plate and in the field. A little over a week ago, Matt Gelb of The Athletic reported that the Phillies are likely to trade or release Castellanos, who has one year left ($20 million) on his five-year, $100 million deal.

Whichever route the Phillies decide to take in the coming weeks and months, they’ll have to find an adequate replacement who won’t be a huge liability in the field, but also provides some pop.

One player who comes to mind and would be a good fit for the Phillies, who also need to get younger in 2026, is Los Angeles Angels outfielder Jo Adell.

Making the case for why the Phillies should entertain a Jo Adell trade

The 26-year-old Adell is coming off his best season as a major leaguer from a power standpoint. He finally resembled the player taken in the first round in 2017. This season with the Angels, Adell slugged .236, with career highs in home runs (37) and RBI (98), across 152 games.

It was the second consecutive season that Adell has played 130 games or more. The veteran outfielder also posted a career-best .778 OPS and a 50.1% hard hit rate, which is good. However, Adell struck out a career-high 151 times at the plate, which you would love to see come down just a bit.

As for his defense, Adell played 89 games in center field and 69 in right field this season. However, the former first-rounder has also experience playing in left field (96 career games).

Based on how the Phillies’ outfield could look next season, you’d like to see top hitting prospect Justin Crawford in left field with Harrison Bader patrolling center (if you can re-sign him), which opens up right field for Adell.

In 69 games in right field with the Angels, Adell sported a .985 field percentage (slightly lower than the league average of .987) and only had two errors in 134 defensive chances. Meanwhile, in center field, Adell had some struggles with a .976 fielding percentage (league average is .991) and five errors (tops in the AL) in 210 chances.

When comparing Adell’s defense in right field to Castellanos’ this season, the latter had the better numbers with a 1.000 field percentage and zero errors. However, as we know, the Phillies often removed Castellanos late in games due to his defense, or lack thereof.

And they were right in their decision as Castellanos had -11 Defensive Runs Saved runs above average. Meanwhile, Adell had a -1 Defensive Runs Saved runs above average, which is more tolerable. For his career, the right-handed power hitter has a DRS of 3 in right field.

With all that being said, Adell is one of the better trade options for the Phillies to go after. If they were to pursue a trade for the Angels outfielder, he would be under team control for two more years before becoming a free agent in 2028.

The Angels know this and won’t just give away Adell, especially with the growth he showed at the plate in 2025. Therefore, if you’re the Phillies, would you consider moving Alec Bohm and a minor league prospect in a deal for Adell? Jim Bowden of The Athletic believes the Angels could be a fit for the 29-year-old third baseman.

Philadelphia will likely be heading in a new direction at third base next season, so why not try to move him for Adell?

Nevertheless, the outfield will be one of the major talking points this offseason for the Phils. They must make a significant move or two so they aren’t in this same spot this time next year.
