Is Willi Castro the Ideal Position Player Target for Padres This Offseason?

[Randy Holt]

There are a couple of certainties when it comes to how the San Diego Padres might set out toward building their 2026 roster this winter. 

The first is a focus on pitching. This is a team losing Dylan Cease and Michael King to free agency. On the same note, Yu Darvish will miss all of next year. The rotation is in a bad way. Even if they're able to backfill some spots from the bullpen, they would then need to shore up the depth in relief. Regardless of how any actual addition transpires, the most notable ones will likely be on the mound. 

The second is that the team is likely going to fill their bench spots in a similar fashion to last year. The Padres went with the volume approach on fringe guys in 2025. Jason Heyward, Jose Iglesias, Tyler Wade, and Gavin Sheets (among others) were all brought in on minor-league deals. Only Iglesias and Sheets stuck around throughout the season, and only Sheets has a longer-term outlook with the organization. Having already signed Pablo Reyes to a minor-league pact, we should expect to see plenty more of that type of contract making their way to Peoria, Arizona next spring for a shot at the roster.

But given how things transpired for the Padres in 2025, it's clear they can't rely solely on minor-league deals to fill out depth spots. When you lose games to injury — as the Padres did with Jackson Merrill, Xander Bogaerts, Ramón Laureano all missing notable time — and need to ensure breaks for the likes of Manny Machado or Fernando Tatis Jr. in the field, the likes of a Heyward or an Iglesias scattered throughout the bench are simply not enough to get the job done. 

Which is why Willi Castro represents the ideal candidate for the San Diego Padres to pursue this winter. 

A former Detroit Tiger, Minnesota Twin, and Chicago Cub, Castro hits free agency coming off a tough stretch following a deadline deal that landed him on the North Side of Chicago. Castro hit just .170 and reached base at a paltry .245 clip following the trade, relying primarily on his approach (16.0 percent walk rate in September) to drum up any semblance of value at the plate. He was worth -0.5 bWAR in 110 plate appearances with the Cubs. 

It's hard to put much stock in a player's post-deadline performance when said player changes his home stadium. Which is why Castro's career line — .244/.313/.384 with a wRC+ of 95 — represents something much more important. Even more notable is the fact that in his last two full seasons in Minnesota, he was an above-average hitter (107 wRC+) who added value on the bases (47 steals between 2023 & 2024). So, while his power has been uneven in his career, there's a steadiness to his bat and baserunning that the Padres lacked entirely in their reserves in 2025. 

Of course, the most important component that Castro brings is in his versatility. While not particularly elite at any position, he continues to log time all over the field in 2025. For Minnesota and Chicago last season, he totaled 264.2 innings at second base, 129 innings at third base, 26 innings at shortstop, 261.2 innings in left field, 35 innings in center field, and 256 innings in right field. His history prior to '25 includes a much longer run at short and in center, too. That level of versatility verges on being considered an everyday player rather than a true bench type. As such, Castro stands to receive a decent contract this winter, even if on a shorter term than some of his peers.

At present, the Padres are without any sort of positional depth both on their roster and in the upper levels of the minors. Their 40-man roster includes Mason McCoy and Will Wagner on the infield, and Bryce Johnson and Tiros Ornelas in the outfield. None of those players offers the level of coverage that Castro can provide from a positional standpoint. McCoy and Wagner are each limited to the dirt while Johnson and Ornelas are stuck on the grass, all with shortcomings on the offensive side. Castro not only offers that coverage in a way that is extremely efficient for this roster but possesses a higher (read: any) upside at the plate.

MLB Trade Rumors projects a two-year, $15 million deal for Castro. Even operating on a tight budget, that's not only something the Padres can afford, but something they should be entirely willing to pursue. The benefit of a player like Castro is that you can roster him and then scatter those six-figure minor-league pacts throughout the roster in a way that allows you to follow a singular skill set without trying to catch some kind of magic in the cheapest way possible. 

On that term and at that price point, Willi Castro isn't only a desirable entity for this roster, but an essential one.
