Astros Sign Christian Walker

December 23: The Astros have officially announced Walker’s signing. According to Chandler Rome of The Athletic, the deal includes a limited no-trade clause and will pay Walker an even $20MM annually per season.

December 20: A new-look Astros club will have a new first baseman in 2025, as the team has reportedly agreed to terms on a three-year, $60MM contract with free agent Christian Walker. The CAA client’s deal is still pending a physical.

Walker’s deal with Houston seems to shut the door on the possibility of a reunion with Alex Bregman. Houston recently acquired Isaac Paredes from the Cubs as part of the trade sending Kyle Tucker to Chicago, and while Paredes could’ve played first base with Bregman in the fold, he’ll be slotted in at third base with Walker now on board. Similarly, this effectively eliminates any chances of Nolan Arenado landing in Houston — an outcome that was all but at the finish line before Arenado invoked his no-trade clause to nix the deal.

Walker, 34 in March, has been a target of the Astros for some time now, dating back to the trade deadline when was reportedly at the top of their wishlist. A deal didn’t get done then, obviously, but Houston still has a need at first base after their three-year deal with Jose Abreu almost immediately imploded on them. Houston first basemen — led by Abreu and Jon Singleton — turned in an awful .226/.291/.360 batting line on the season in 2024. Walker, meanwhile, hit .251/.335/.468 — almost an exact match for the .253/.333/.464 line he carries through 3171 plate appearances dating back to the 2019 season.

On top of his quality results at the plate, Walker has emerged as arguably the premier defensive first baseman in MLB. He’s won three straight Gold Glove Awards in the National League and leads all first basemen in Defensive Runs Saved (33) and Outs Above Average (39) over the past three seasons. Matt Olson (27) and Carlos Santana (20) are second in those respective metrics. Walker’s defensive excellence at his position has essentially been unmatched.

Both Walker and the recently acquired Paredes are strong fits for the Astros, given the short left field porch at the newly renamed Daikin Park. That’s more true of Paredes, who’s one of the game’s most dead-pull and prominent fly-ball hitters. Walker has more of an all-fields approach, but when isolating his splits on pulled batted balls, he ranks 15th among qualified hitters in fly-ball rate (32.2%). Put more simply, Walker may spray the ball around a bit more than Paredes, but when he does pull the ball, he lifts it far more often than the vast majority of big league hitters. For a right-handed hitter with plenty of pop in his bat, that should play quite nicely with a 314-foot left field porch.

It’s been a bull market for free agents this offseason, and Walker had accordingly been hoping to land a four-year deal. He’ll “settle” for a year less than that on a deal that aligns with early expectations. His three-year, $60MM deal is an exact match for our predicted contract back on MLBTR’s annual ranking of the offseason’s top 50 free agents.

The $20MM annual salary on the contract puts the Astros north of the luxury tax threshold for what would be a second straight season. RosterResource now projects them at $244MM of luxury obligations — $3MM north of the $241MM tier-one threshold for the coming season. Their bottom-line payroll will depend on how that $60MM is divided over the three years of the deal, but if it’s evenly distributed, Houston would be just over $225MM in terms of actual player salary. (The luxury tax is calculated separately and based on the average annual value of all the team’s contracts.)

It’s still possible the Astros could duck back under the tax threshold. They’re reportedly telling teams they don’t intend to trade top starter Framber Valdez, but they’ve been exploring the trade market for reliever Ryan Pressly, who’s set to earn $14MM in 2025. More speculatively, they could also gauge interest in backup catcher Victor Caratini and his $6MM salary, then turn that role over to Cesar Salazar, who hit well in Triple-A and the majors this past season.

Dropping back under the tax line, however, doesn’t appear to be any kind of mandate. Owner Jim Crane said earlier in the winter that he “had the wherewithal” to cross that line and match his 2024 levels of spending if the right scenario presented itself. At the time, few envisioned that would entail trading Tucker and letting Bregman walk, but the Astros have been averse to the types of long-term megadeals both players — Tucker in particular — are expected to command. Houston hasn’t given out a contract longer than Yordan Alvarez’s six-year, $115MM contract or Jose Altuve’s six-year, $157.5MM extension under Crane’s ownership, the latter also being the largest guarantee in franchise history.

As a result, the Astros will give out their second three-year deal to a mid-30s first baseman in the past three years. Houston signed the aforementioned Abreu to a $58.5MM deal in the 2022-23 offseason and will still be paying Abreu $19.5MM this coming season after releasing him at the contract’s halfway point. That deal was negotiated by Crane himself and senior advisor Jeff Bagwell, as it came in the lull between the team’s dismissal of former GM James Click and the hiring of current GM Dana Brown. Astros fans may feel some trepidation about another multi-year deal for a first baseman well past his 30th birthday, though it bears mentioning that Abreu was 36 in year one of his contract; Walker will be 36 in the final season of this deal.

Walker declined a $21.05MM qualifying offer from the D-backs at the end of the season. As such, he’ll cost the Astros their second- and fifth-highest picks in the 2025 draft, as well as $1MM of space from their league-allotted bonus pool for international amateur free agency. That’s the steepest penalty possible for signing a qualified free agent, but the Astros find themselves in that tier as a result of exceeding the luxury tax threshold in 2024. The fact that they exceeded the tax threshold also means they’d only receive a compensatory pick after the fourth round in the now-likely event that Bregman signs elsewhere.

As for the D-backs, they’ll receive a comp pick after the first round, because Walker’s agreement is for more than $50MM guaranteed. It’ll be a nice parting gift, but Walker’s production will be tough to replicate with in-house options. Former top-10 draft pick Pavin Smith hit well in 158 plate appearances last season, but that was his first big league success in parts of five seasons and came in a small sample. The Snakes can hope for a similar late-bloomer trajectory to the one taken by Walker, but odds are against that. They could look to affordable alternatives in free agency (e.g. Carlos Santana, Justin Turner, a Josh Bell reunion) or sift through a deep trade market of first base options that includes Yandy Diaz, Josh Naylor, Nathaniel Lowe and perhaps Triston Casas (though the asking price on Casas would be extreme and surely cost the D-backs some coveted young pitching).

Robert Murray of FanSided first reported that the two sides were in advanced talks and closing in on a deal. Jim Bowden of The Athletic and MLB Network Radio reported that an agreement was in place, pending physical. USA Today’s Bob Nightengale reported the terms.
