Astros face a $20 million Christian Walker dilemma: Why trading him could make Houston better

"I come to praise Caesar, not to bury him." -- William Shakespeare

My comrade in arms has already covered this question from his end, but I always approach things from a more statistical standpoint. It is also why I delayed this question on purpose. The Astros flamed out of the playoffs in two weak games for the second time in three years. Walker was particularly anemic in the series and very vocal after the series. Apparently, he did not like the booing he received from the Houston faithful.

The normal course of these things is to reflexively call for the player to be sent out of town. There are certainly more than a few Houston fans that would like to see both Walker and Bennett Sousa shipped out because of their comments about the booing. I usually make it a point not to react emotionally to those comments or the results of two baseball games. Both are small samples that skew everything else. Obviously, the situation with Walker exists on multiple levels. Let's start with the basic performance numbers.

Christian Walker is a career .245 hitter. So, his .232 average in Houston is not completely beyond the pale. According to baseball-reference.com, his career per 162 numbers include 29 home runs a season with 81 runs scored and 88 RBI. One of my biggest pet peeves is when people expect more from a player by virtue of him being paid. The most famous example of that was when the Astros gave Carlos Lee six years and 100 million dollars. Paying him that money didn't suddenly make him a better hitter and it was never going to.

It is true that Walker has a .772 career OPS, so the two seasons in Houston were under that norm, but he is also approaching his mid thirties. I'm not quite sure what anyone was expecting. This brings us to the second layer of the analysis: How do the numbers above compare to that of the league? This is where we can bust out our OPS+, wOBA, xwOBA, and wRC+ for comparison sake.

I promise that OPS+ and wRC+ are actually different numbers. wRC+ is going to include base running and for some players that will make a significant difference. Walker is not one of those players, so they end up looking the same. I think what is important here is how similar the 2025 and 2026 numbers are. Walker is consistent at least over a full season. He obviously was streaky within those seasons which is probably why some people soured on him.

The one major difference between 2025 and 2026 was actually on the defensive end. He is -7 in 2025 according to defensive runs saved, but +3 this season. That is worth a full win and can explain the difference between his BWAR scores in 2025 and 2026. He was identical +7 in fielding run value both seasons and +2 and +3 in outs above average respectively. That is why his FWAR has always looked better than his BWAR.

Overall, that makes Christian Walker an average baseball player. He is league average offensively and slightly above average defensively. When I say average that is not meant to be a slight on him. Average baseball players do not grow on trees. Certainly, the Astros would love to have an average player at three or four other positions on the diamond. However, this is where the praise stops and the reality begins.

We honestly don't know what the future holds for the collective bargaining agreement. We don't know if there will be a hard cap, a stronger tax system, or if it will essentially be what is in place now. What we know is that Jim Crane is reluctant to go beyond the current tax threshold. I am not going to tell a grown man how to spend his money. I think he could potentially afford to spend beyond that, but that is conjecture on my part. Given the Astros division and where they have been, that 240-250 million dollar limit should be more than enough to outfit a winning baseball team.

In that universe, paying an average baseball player at a position where there are alternatives is a luxury you probably can't afford. It isn't so much that you are a better baseball team without Christian Walker. It is that you are a better baseball team if you are able to spend that 20 million dollars on something else you need. Isaac Paredes can slide to first base and you can use the financial savings (on top of what you get for Walker in trade) to get more pitching or maybe a corner outfielder that can provide league average offense.

That's the easy part. The difficult part is finding a trade partner. What is highly likely is that a trading team will either give you their own garbage or they will demand that you pick up part of the tab. One distinct possibility would be trading him to the Mets for Kodai Senga. Senga makes 15 million dollars, so you would save close to five million and potentially add a pitcher that could be useful. Senga closed the season strong as the Mets closer after failing in the rotation.

Could he be a somewhat expensive replacement for Bryan Abreu for one season? Could Brent Strom find something and unlock him as a starter? These are the kinds of deals that are likely on the table for the Astros. The other option is likely picking up half of his contract so that you save ten million and get very little in return.

These are decisions to be made by the next general manager. You could make a credible argument that either option makes you a better baseball team overall. You could also argue that keeping Walker would be preferrable to adding a Senga or paying someone ten million dollars to get him off your roster. None of these are easy decisions, but they are decisions that will have to be made.
