Mariners must see the writing on the wall about Julio Rodríguez in center field

The Seattle Mariners are accustomed to Julio Rodríguez as a unicorn. A center fielder who can hit and field with the best of them? They don't make those anymore. Went out of demand sometime in the 90s. Just can't get the parts these days.

But for how much longer can this version of Julio survive?

Even if he wasn't the culprit, Julio was certainly a culprit in how wrong the 2026 season ended up going for the Mariners. He's threatening to finish the year with career lows for OPS (.718) and WAR (3.1). He hasn't been the same hitter since his concussion in July, while strike-zone discipline that has gone from bad to worse looks like more of an existential threat to his offense.

Then there's the defense. This is about to be the first year of Julio's five-year career that he'll finish in the negative for Defensive Runs Saved (-5) and Outs Above Average (-2). The "No Fly Zone" has too often looked like a "Yes Fly Zone," including when he let that harmless fly ball fall in front of him on Wednesday.

A deep dive into Julio Rodríguez's metrics reveals cause for concern

Mental gaffes are mental gaffes, and the Mariners don't have much choice but to hope that a stern talking-to can prevent those in the future. What the team should really be worried about is the possibility that, even at 25, Julio has already lost a step out in center field.

To this end, here's how his jump components are trending:

These numbers are meant to answer the question of "How many feet did he cover in the right direction in the first three seconds after pitch release?" The jump is feet covered in the first 1.5 seconds. The burst is feet covered in the next 1.5 seconds. The route compares feet covered in any direction to feet covered in the right direction over the full three seconds. All results are reported in feet above or below the major league average.

Julio's routes have gotten better with experience, but his reactions have gotten worse and his bursts aren't living up to his peaks of 2023 and 2024. The big picture as presented in "Feet vs. AVG" suggests that he's not getting better at the crucial act of getting after fly balls.

That isn't ideal, and then you can add the question of whether Julio has the closing speed he once did. His baserunning speed, at least, is not what it once was. He's down from 29.7 feet-per-second as a rookie in 2022 to 28.7 feet-per-second as a five-year veteran in 2026.

History suggests having Julio Rodríguez as a unicorn can't last forever

What can be hard to remember in moments like these is that offense isn't the only thing that fluctuates in baseball. Guys can have bad defensive years, too, and that could be all we're looking at with Julio's 2026 season.

What is nonetheless worth considering is the historical precedent for center fielders like Julio. Or, more accurately, the lack thereof.

He's listed at 6-foot-4, 228 pounds. Want to know how many guys that size and larger have ever played 100-plus games in center field in a season even once? Just nine. Want to know how many have done so five times? Just two. It's Julio and Matt Kemp, who likewise did so in five consecutive seasons between 2008 and 2012. Even if Kemp was two years older in 2012 than Julio is now in 2026, that he subsequently degraded in 2013 and beyond suggests something ominous.

The writing is on the wall that guys with Julio's body type don't necessarily belong in center field on a permanent basis. Between that and what happened with his defense this year, it should be time for the front office to discuss whether a position change is the best thing for him and the team.

Indeed, the timing is perfect for this conversation. With Randy Arozarena set for free agency, the Mariners are about to have a corner outfield spot open up. They could move Julio to left field (or right field, with Lazaro Montes or whoever going to left) and then sign a stopgap center fielder to bridge the gap to Jonny Farmelo. Daulton Varsho, for example, could bring proven elite defense to T-Mobile Park in this scenario.

What the Mariners must be wary of is needlessly burning Julio out. Even if he is on a club-friendly deal that could last as long as 2034, it's better to be proactive assuring it will remain club-friendly than to risk letting age and wear and tear turn him into an albatross.
