Ever since the club dealt superstar slugger Paul Goldschmidt to the Cardinals prior to the 2019 season, the Diamondbacks have been relying on Christian Walker to pick up the slack at first base. In his first three seasons as a regular, Walker was somewhat uneven as he posted roughly league average numbers with the bat overall (103 wRC+) thanks to decent but unimpressive strikeout (24.1%) and walk (9.6%) rates that combined with only average power. While Walker posted above average defensive marks during that time, that wasn’t enough to make him an impact player at a bat-first position like first base, leaving him to generate just 4.1 fWAR over his first three seasons after taking over for Goldschmidt.
Since then, however, the slugger has proved to be a late bloomer and taken off in a big way. A breakout 2022 season saw Walker nearly match that aforementioned three-year total in a single season with a 4.0 fWAR campaign where he slashed an excellent .242/.327/.477 (122 wRC+) while appearing in 160 of the club’s 162 games and clobbering 36 home runs. That was good for the sixth-highest home run total in the league that year, and Walker paired it with a 19.6% strikeout rate and 10.3% walk rate. Only Yordan Alvarez and Anthony Rizzo joined Walker in striking out less than 20% of the time, walking more than 10% of the time, and clubbing at least 30 homers that year. 2022 also saw Walker flourish defensively, as his +14 Outs Above Average and +17 Defensive Runs Saved easily earned him his first career Gold Glove award as he ran circles around the competition, with Matt Olson’s +4 OAA and +6 DRS standing as the next-best defensive resume that year.
Some skepticism is always necessary when a player on the wrong side of 30 enjoys a breakout season, but Walker has subsequently proven his fantastic age-31 campaign to have been largely sustainable. It’s been more of the same in each of the last two years, as Walker has posted identical 119 wRC+ figures in both 2023 and ’24 while slugging a combined 59 homers and generating 6.9 fWAR. Over the past three years, only Goldschmidt, Olson, Bryce Harper, and Freddie Freeman have generated more fWAR than Walker at first base, cementing him as one of the league’s premier first basemen.
Each of those four sluggers ahead of him have played on nine-figure deals in recent years, but even as Walker heads into free agency for the first time in his career it would be a shock if he were to join them in landing a contract anywhere close to that price point. The biggest reason for that is his age; Walker will turn 34 the day after Opening Day 2025, making him two years older than Freeman was when he signed on with the Dodgers and a year older than Goldschmidt was when he signed an extension in St. Louis. While it’s certainly not unheard of for hitters to remain effective into their mid-to-late thirties, it would be an incredibly risky bet for a club to offer Walker even a four- or five-year deal given the typical aging curve of MLB players.
Walker’s age isn’t the only factor at play here, either. While his platform season with Arizona in 2024 was largely a successful one, an oblique strain cost the veteran just over a month late in the year. Walker’s availability has been a major asset in recent years; the veteran appeared in more than 90% of the Dbacks’ games from 2019 to 2023, including just seven games missed between the 2022 and ’23 seasons combined. Given that, it’s surely concerning to prospective suitors that Walker now has a significant oblique injury in his recent history—particularly given the fact that he also suffered from oblique problems in 2021 that resulted in multiple trips to the IL.
As the veteran enters free agency not only on the cusp of his mid-thirties but on the heels of a fresh reminder of his injury history, it’s fair to wonder what sort of contract will be available to him on the open market. Other veteran first basemen like Rizzo and Jose Abreu have managed to get deals in the two-to-three year range for $15-20MM annually, and it’s not hard to imagine Walker getting a similar deal. If Walker figures to land a deal in a similar range, that would likely place him squarely on the bubble for a Qualifying Offer, which this offseason will be a one-year deal worth $21.05MM.
That’s likely a slight overpay in terms of AAV for Walker’s services, but it could nonetheless be an attractive gamble for the Diamondbacks to take given Walker’s importance to the club’s lineup in recent years and the short-term nature of the commitment. RosterResource at Fangraphs projects Arizona for just under $97MM in commitments for the 2025 season, though that figure shoots up to around $138MM after factoring in options for Jordan Montgomery, Eugenio Suarez, and Merrill Kelly.
That would still leave the club with around $35MM of budget space if they were to match their 2024 spending totals, although a $21.05MM commitment to Walker would eat up the majority of that space, leaving them without much room to replace other outgoing free agents such as Joc Pederson and Randal Grichuk. Of course, that assumes that Walker would accept the offer if it’s extended to him. If he were to decline it and sign elsewhere, the Diamondbacks would receive a compensatory pick following either the first or second round of the 2025 draft in exchange for losing Walker, allowing them to ensure they won’t lose a key cog in their lineup for nothing.
Should the Diamondbacks extend Walker the Qualifying Offer this winter and risk paying him more in 2025 than he would earn otherwise, or should they allow him to enter free agency unencumbered and risk losing him for nothing? Have your say in the poll below.
