5 wild blockbuster moves the Cardinals should consider at the trade deadline

Let me be clear, I don't think the St. Louis Cardinals are going to do anything wild or worthy of the term "blockbuster" at this year's trade deadline. That doesn't mean I don't think they could make "big" moves, but I highly doubt they will be making a huge swing this July.

To be frank, I don't think that is necessarily the wrong approach with this team. Most big splashes they could try to make would deplete their farm system and still leave them behind the best contenders in baseball in terms of World Series odds. I am by no means advocating for their biggest moves to be for guys like Tyler Anderson or Kevin Pillar, but I don't blame them for staying out of the Garrett Crochet sweepstakes, for example.

Still, the more and more I've thought about it, the more I have at least been intrigued by the idea of some potential bigger swings the Cardinals front office could make. I've been playing around with different trade scenarios involving some teams who have pieces the Cardinals would love to have, but at a massive cost. Again, while I doubt the Cardinals make a move of that magnitude over the next week, I think it's at least interesting to talk about what kinds of deals would make sense for them to consider.

Consider this a fun exercise about those "what if" scenarios we feel confident won't happen, yet if the Cardinals decided to be aggressive, it could make a lot of sense for them. For the following five deals, here are the parameters I worked with that made the deals make sense, even at the extreme costs they would require:

1. The deal has to hurt. If you're drawing up a blockbuster deal for the Cardinals and you feel completely comfortable with the pieces you're giving away, it is probably far from what it would actually take to pull off such a deal.
2. The deal has to address one or more of the Cardinals' current needs - front-line starting pitcher, bullpen help, or a right-handed bat for the lineup.
3. The player(s) the Cardinals are acquiring need to have some control beyond 2025. I do not see the Cardinals considering a blockbuster move where they move significant young talent in order to acquire someone who could be gone in a year and a half. There are great players that fit that mold like Nathan Eovaldi, Zach Eflin, and others, but those are not blockbuster deals by any means. But the kind of blockbuster player that does rule out is someone like Vladimir Guerrero Jr. - a fun idea, but I don't see the Cardinals signing him long-term, so why would they give up a haul for the short time they'd have him?

Consider this exercise a list of deals I think the front office should at least pause and talk about for a while. It doesn't mean they should do any or all of these deals, but these are the kinds of packages that you at least have to have a meeting about, and probably multiple follow-ups. They are the kinds of moves that, while risky, could transform the team for both now and the future.

With that being said, here are five blockbuster trade ideas that the Cardinals should consider at this year's trade deadline.

Note: This was written before the recent news that Mason Miller has landed on the injured list with a broken hand.

Why this makes sense for St. Louis in the immediate future:

I mean, come on. Imagine a team trying to score off of Ryan Helsley AND Mason Miller at the Cardinals' push for a postseason berth, and how much of a weapon those two become in October. Talk about shortening games, the Cardinals would be shutting down the 8th and 9th innings against the best offenses in baseball, and allow the mixture of Andrew Kittredge, JoJo Romero, Ryan Fernandez, Matthew Liberatore, and others to lock down the 6th and 7th innings of tight playoff games.

We have seen dominant bullpens carry teams deep into October before, and I'm not sure I can think of a single duo in recent history that could compare to what Miller and Helsley would provide this October. While the rotation would still be a concern, the depth and quality that would be in the Cardinals' bullpen after this deal would allow the Cardinals to pull their starters at the first sign of trouble and attempt to completely shut down and opponent with their stable of arms.

In the case of Brent Rooker, he is exactly what the Cardinals' offense needs right now - someone who can mash left-handed pitching (.948 OPS against both lefties and righties this year), hits for power, (23 HR in 365 PA) and is incredibly productive with runners in scoring position (1.214 OPS with RISP). He is the absolute perfect fit offensively for this club, and with how badly they could use another bat like his, you find a way to make room for him

Rooker is primarily a DH, but he can play corner OF occasionally as needed. Paul Goldschmidt and Nolan Arenado (but mostly Goldschmidt) have not been good enough this year to "need" to DH when they need a day off their feet, so the Cardinals could DH Rooker every day and have him cover the corner outfield with Contreras needs a day off.

Why this makes sense for St. Louis long-term:

This is a massive price to pay for the Cardinals, but the payoff would not just be for their 2024 stretch run, but for multiple seasons to come.

Rooker is not a free agent until 2028 and Mason Miller does not hit the open market until 2030, so while the Cardinals would be giving away a ton of control between Jordan Walker, Nolan Gorman, Tink Hence, and Ivan Herrera, they would be acquiring a lot in return between Miller and Rooker.

I'm still a believer in Jordan Walker, and his 90th percentile outcome as a player blows Rooker out of the water value-wise, but if we are being honest, wouldn't you smash a button right now if you could lock in Rooker's offensive production for Walker over the next few years? Turning Walker's potential into the reality of Rooker is something to consider when they acquire a talent like Miller in the deal. No, I would not swap Walker for Rooker right now, but I would move Walker and more for Miller, which is what this deal really is.

In this deal, the Cardinals are only giving up one player who is currently contributing in St. Louis is Gorman, but his inconsistencies have been a major problem for St. Louis this year and the left-handed production from Alec Burleson, Brendan Donovan, and Lars Nootbaar lessens the need for him long-term. Turning him into the right-handed production they desperately need makes a lot of sense.

Giving up Tink Hence is a tough pill to swallow, but we can only hope Hence is as impactful of an arm as Miller is today, and Miller has only one year less of control! Herrera is a valuable piece as well but could be used to close this deal for an Athletics team that is continuing to build for the future.

Also don't forget this nugget, Mason Miller still may get a chance to become a front-line starter again. The Athletics moved Miller to the bullpen to keep him healthy for 2024 and allow him to produce, and then try him in the rotation again in 2025. Obviously Miller has been far more dominant than anyone could have imagined, so it may not be quite as simple to make that move. But for the Cardinals, they would have that option if they desired.

If the Cardinals wanted to keep Miller in the bullpen, then the Cardinals could look to flip Helsley in the offseason to recoup some of the value they gave up, which also has to be taken into account. Helsley is a free agent following the 2025 season, so it could make sense to move him instead of paying him.

This would be a wild deal and I'm not even sure the Athletics say yes, but if I am in the Cardinals front office, we are having a bunch of meetings to talk through the ramifications of a deal like this and figuring out if we should go for it. The fact that Miller and Rooker are cost-controlled going forward makes this deal very appealing, even with the amount of talent they would be giving away here.

Why it makes sense for St. Louis in the short-term:

This trade may be far more realistic come the offseason, but the Cardinals and Mariners continue to feel like the answer to each other's questions, and whether it is Bryan Woo or one of the seemingly endless set of arms the Mariners have on their roster, the Cardinals would be wise to acquire one.

KMOV's Brendan Schaeffer and I briefly discussed on our new podcast "Philosophical Differences" how the Mariners and Cardinals seem like that match made in heaven on paper, but in practice, both sides are going to have a hard time coming to an agreement due to how they value each of their bats and arms. There isn't a clear one-for-one swap that makes sense for both sides, so one side will likely need to include a kicker to get something done if they ever did. Still, with how desperate the Mariners are for offense, they may have to change that tune.

I'm sure the Mariners would much rather take Emerson Hancock and another piece to acquire someone like Gorman, but in this scenario, I am going to have the Cardinals taking Gorman and Thomas Saggese to acquire Mariners' starter Bryan Woo.

Woo debuted for Seattle last year, posting a 4.21 ERA in 18 starts, flashing his electric stuff in the process. Woo has battled an injury this year but has stepped up his game even more, posting a 2.54 ERA in his 10 starts. Woo still has room to grow in his game in terms of missing bats, and if he is able to get more punchouts as the years go on, he could be a future front-line starter. The results certainly feel like one right now.

Why it makes sense for St. Louis long-term:

The Cardinals have young arms coming in Tink Hence, Quinn Mathews, and Cooper Hjerpe along with others, but getting a guy in their rotation now with upside and control would be a major get. It would be fun to swing higher for George Kirby or Logan Gilbert, but I really do not see the Mariners parting with either of them any time soon.

The Mariners' offense is so bad right now, and they just had Julio Rodriguez land on the injured list as well (not that he's been all that great either). They need to add multiple pieces to this offense at the deadline, and Gorman would be a valuable start. His inconsistencies won't be pleasant, but his ability to take over games with his power would be huge for Seattle.

I've already said it a few times, but losing one left-handed bat is not the end of the world for the Cardinals. This scenario would actually allow St. Louis to bring back Ivan Herrera and DH him frequently with the at-bats that need to be covered, and assuming they add another right-handed bat for the outfield, Donovan can slide back to second base. Gorman has been underwhelming overall this year, so while he still could produce down the stretch, the Cardinals aren't losing someone who is currently producing.

Why it makes sense for St. Louis in the short-term:

I know this will never happen. There is just no way that the Cubs would trade Justin Steele to the Cardinals. I also do not see the Cardinals giving up this kind of talent to their division rival. But let's be honest, the framework makes a lot of sense.

The Cubs plan on selling at this year's deadline after another disappointing season. Chicago is not going to go into some full-scale rebuild, but there are rumors that they will consider maximizing Steele's value to help the club going forward. My oh my, Steele would be the perfect fit with Gray at the top of the Cardinals' rotation.

In 15 starts for the Cubs this year, Steele has a 3.07 ERA while covering 91 innings, and Steele continues to be elite at not allowing hard contact and getting hitters to expand their zones. Not only that, but lefties tend to excel when pitching at Busch Stadium, so we could even see the best of Steele yet to come in a Cardinal uniform.

Gray and Steele would give the Cardinals a formidable duo this October, and in this package, not require a single piece from their Major League roster to be moved. Hence is a top pitching prospect in all of baseball that would bolster an already loaded Cubs system, and Gordon Graceffo would provide them with further pitching depth that can cover innings now as well.

Ivan Herrera has his clear weaknesses defensively, but the Cubs have had terrible production from their catcher position ever since they let Willson Contreras walk in free agency. Developing Herrera behind the plate now could give the Cubs an everyday catcher to match up with Contreras in the coming years.

Why it makes sense for St. Louis long-term:

Steele is not a free agent until 2028 giving the Cardinals a cost-controlled arm for years to come. Steele is who we hope Tink Hence can become, and a bird in the hand is better than a bird in the bush. Herrera and Graceffo is not a crazy premium to pay along with the potential of Hence to get what we know Steele is.

What doesn't make sense for them long-term is giving the Cubs assets, but hey, if someone else is going to do it, does it really matter all that much? I'm sure the Cubs would prefer to squeeze St. Louis for more value though, or just deal Steele elsewhere.

Why it makes sense for St. Louis in the short-term:

The last one on this list is a twist on a popular fan idea that has floated around recently. Bobby Miller has struggled mightily this year, leaving some Cardinals fans to point to a Walker-Miller swap making sense for both sides. Personally, a Nolan Gorman version of this swap makes even more sense for both sides.

Let me reiterate one more time that I still have a lot of faith in Walker. I just do. This guy is so talented, and he's still just 22 years old. And why are we forgetting that he was a productive big leaguer last season, especially after his brief Triple-A stint where he came back up hitting 20% above league average the final four months of the season? Walker is the kind of talent I would much rather go down sinking with, rather than "sell low" on.

I do think the Miller idea is interesting though, but with the Dodgers in win-now mode, Gorman could slot in at either of their two weakest positions offensively right now - second base and third base - and provide Los Angeles with a third power-hitting left-handed bat for their lineup behind Shohei Ohtani and Freddie Freeman.

What the Cardinals would be doing here with Miller is banking on the idea that he can figure things out and get back on track to being a true front-line starter. If Miller was performing like we expected him to this year, Gorman would be nowhere near enough value to get a deal done. This deal would only work if Los Angeles is willing to sell a bit low on Miller while banking on the upside of Gorman as well.

In 22 starts for the Dodgers last year, Miller posted a 3.76 ERA while accumulating 2.8 fWAR in the process. He was among the best in baseball when it came to inducing groundballs, not giving up good contact, and of course, fastball velocity. Miller's five-pitch mix was led by a deadly fastball/sinker combination that his change-up and curveball played well off of.

This year, Miller has posted an 8.07 ERA in his seven big league starts, and it is truly dumbfounding how badly things have gone for him. Miller's slider has really let him down this year, and he will either need to find a way to turn that pitch around or ditch it altogether in order to get back to his prior success.

This deal doesn't give the Cardinals much in the short-term, but the potential long-term gain is why they do this deal.

Why it makes sense for St. Louis long-term:

Sonny Gray has been a great addition to the top of the Cardinals' rotation, but he's not getting any younger, and while St. Louis does have exciting arms on the way, we all know how those arms could easily flame out (just look at the Cardinals' top-end pitching prospects in the mid-2010s). Adding Miller to their stable of future arms like Hence, Mathews, and Hjerpe would go a long way toward improving the future outlook of this staff.

As we've seen around the game this year, you can never have enough pitching. Honestly, it even feels like the teams that are the most loaded with pitching talent tend to be the teams that need more arms by the deadline. Injuries are just inevitable with pitching in today's game, so having a bunch of "dudes" rather than placing all of your eggs in one basket is wise.

Losing Gorman wouldn't be easy, but it's not hard for me to wrap my head around how they can replace him internally or go after a veteran bat this offseason. But getting a talent like Miller is something I just don't see many ways for them to actually pull that off, so this is worth considering.
