The months of Nolan Arenado trade rumors came to a close on Tuesday when the Cardinals dealt the 10-time Gold Glove winner to the Diamondbacks. St. Louis paid his contract down to two years and $11MM, while Arizona parted with last year’s eighth round draft pick (Jack Martinez). The Cardinals had made no secret of their desire to shed a portion of Arenado’s salary and open space at third base for younger players, with Nolan Gorman likely to get the first run.
Arenado’s full no-trade clause gave him say over his destination. He had a limited number of teams to which he would have accepted a deal last offseason. He expanded that list this winter and discussed the decision on an introductory Zoom call with reporters. “Seeing where (the Cardinals) were headed the past few years, it was very evident that there’s a step they need to take,” Arenado said (link via Sam Blum of The Athletic). “Letting these young guys go and finding out who they are, and who their identity is. I think I’m just kind of in the way of that, in a sense. I kind of always felt like that last year.”
Asked about the appeal of the Diamondbacks specifically, Arenado pointed to their position player core built around Corbin Carroll, Geraldo Perdomo and Ketel Marte (video provided by Steve Gilbert of MLB.com). He noted the geographic proximity to his native Southern California and expressed excitement about the team’s playing style. He’ll take over as the everyday third baseman and should at least provide a strong glove, though it remains to be seen how much he has left in the tank offensively. He’s going into his age-35 season on the heels of a .237/.289/.377 showing over 107 games.
Cardinals president of baseball operations Chaim Bloom told Derrick Goold of the St. Louis Post-Dispatch that conversations with the Diamondbacks developed quickly. Arizona had been involved in the market for free agent third baseman Alex Bregman, who agreed to a five-year deal with the Cubs on Saturday. It wasn’t until last Friday that reports emerged that they had firmly pulled Marte off the trade market. While the Cardinals and D-Backs had discussed Arenado throughout the winter, it seems talks accelerated in the wake of the Bregman/Marte developments.
Goold writes that the Snakes had also been among the teams to reach out to the Cards about Brendan Donovan. Their interest in the left-handed hitting utilityman had not previously been reported. That’s unlikely to mean much at this point. St. Louis is widely expected to trade Donovan, but teams like the Mariners and Giants appear more engaged. Arizona has Marte, Perdomo and Arenado in the three infield spots to the left of first base. Donovan would be an upgrade in left field, but a team with a second base need will probably be more motivated to part with high-end prospect talent.
Arizona’s focuses now seem to be a right-handed hitting first baseman and the bullpen. Franchise icon Paul Goldschmidt has made sense as a target in the former role all offseason, and the acquisition of his longtime St. Louis teammate only strengthens that fit. They may need to take more of a patchwork approach to the bullpen. This week’s one-year, $1.55MM deal to bring back Taylor Clarke is their only big league bullpen pickup to date.
Clarke projects as more of a middle or long reliever than a leverage arm. That’s true of essentially everyone in the Arizona ‘pen until A.J. Puk and Justin Martinez return from last year’s elbow surgeries. General manager Mike Hazen acknowledged that while the front office would love to add an established late-game arm, that’ll be challenging at this stage.
“Would I like to have somebody that has a clear pedigree of pitching in the eighth and ninth inning? That’s an easier answer. I’m not sure what we’ll have access to in that way,” Hazen told Nick Piecoro of The Arizona Republic. He acknowledged they need to continue adding to the bullpen this offseason but suggested the biggest impact would probably come from internal improvements and hopefully getting Martinez and Puk healthy. Arizona prioritized upper minors pitching in last summer’s deadline activity. Brandyn Garcia, Juan Burgos and Andrew Hoffmann all came over as inexperienced but essentially MLB-ready bullpen pieces.
Of the injury returnees, it seems Puk is further along. Piecoro writes that the D-Backs hope to get the southpaw back within the first few months of the season, while Martinez is targeting a second half return. Puk underwent internal brace surgery in late June. Martinez required a full Tommy John reconstruction, which comes with a longer recovery timeline. It was the second elbow ligament procedure of each pitcher’s career, as they’d both had Tommy John surgeries during their prospect days.

Months of Arenado trade talk? More like years. His defense is still very solid. His warning track flyouts at Busch may find the seats in the desert. For the price, the Snakes may be getting a steal. Best of luck to Nolan.
If that excitement he has now playing in AZ somehow translates to on-field performance this team could be a sleeper. They got a solid squad out there and Burnes gonna be back for the 2nd half.
A couple of bullpens additions and this team should be right back in the postseason mix.
A few names I like for them: Chafin, Brasier, leclerc, Rodgers, Hendricks, sims, and poche. All can be brought in on <5 mil 1 yr deals or even minor league deals for a few to add veteran depth to the pen.
If they want to spend a little more Kopech who I really like as a closer option for them and Dominguez are other options probably on 2 year deals.
I don’t see many great trade options for them either maybe Estévez from KC or Clevenger from Tampa
Andrew Hoffman pitched fairly well with the Royals last season and I think he could be good this year in the bullpen. Brandyn Garcia also could develop in the bullpen as a lefty who gets a lot grounders.
AZ has some nice arms at the back, its Ginkle, Clarke and Loaisaga in high leverage innings that is soft.
Thats difficult because you’d like to keep ths young guys on thd team and developing in the majors. If you add an arm or two, its likely two of the rookies back to AAA.
Difficult to resolve the bullpen in AZ this season. For AZ to be successful, Ginkle and Clarke have to step up their game and Hoffman and Garcia have to nail down their routines as short relief, middle relief, long relief and potential spot starters. A lot being asked of Hoffman and Garcia this season.
Offense is interesting, with Vargas and Barossa on the bench, they can get eight lefties in the lineup against a RHP who has a soft LHB split. That is a nice stack.
Defense will be real good.
Diamondbacks improve with the addition of Nolan Arenado. Arenado will provide them with solid defense at 3rd. He is no longer is the type of hitter to bat 3rd or cleanup, but will be adequate as the 7th or 8th place hitter in the lineup.
With Burnes, Puk and Martinez out the first half it’s really hard to see the dbacks close enough to make a run.
Late inning pen isn’t looking good.
1-3 hitters are really good but after that is questionable
Kelly is a solid number 3 starters. After that’s is a bunch of 4/5 guys.
They would need to be a top 6 team in the NL. Teams I currently have ahead of them…dodgers, Phillies, brewers, cubs, padres, Mets, Braves, giants, reds…close to them pirates and marlins. Teams that I can say they are better than…cards and Rockies.
I think they have a chance to be a good team in 2027, if there is even a season.
Ryne Nelson was a solid #2 pitcher in 2025. Brandon Pfaadt would need to make a step forward this year for AZ to be in contention.
I remember another 3rd baseman the D backs got in his 30’s.. Worked out pretty well.
Matt Williams-
Are there comparisons here?
Lol @Dbags…haha
