DALLAS -- It looks likely that the Diamondbacks will come away from the Winter Meetings without having signed a free agent or completed a trade, but that doesn't mean they haven't made progress towards getting something done.

The meetings wrap up Wednesday afternoon following the Rule 5 Draft.

"Probably not, but who knows?" Arizona general manager Mike Hazen said of getting something done in the next 24 hours. "I mean, there's definitely trades that could happen. It's just that I don't feel like we're at the finish line of anything. There's concepts of things that we could do that we're still considering."

The Diamondbacks are looking to add to their offense after first baseman Christian Walker and the DH platoon of Joc Pederson and Randal Grichuk became free agents. Arizona would also like to add at least one more arm at the backend of their bullpen, preferably one with closing experience.

When it comes to making trades, though, Hazen has found that in order to get a player that can contribute right away he will likely have to give up a player on his current roster rather than a prospect.

The Diamondbacks have two areas of surplus that they could deal from -- center fielders and starting pitchers.

With Corbin Carroll, Lourdes Gurriel Jr., Jake McCarthy and Alek Thomas, Arizona has the flexibility to deal either Thomas or McCarthy. Both players can play center field, with Thomas' defense there amongst the best in the game and a number of teams want to add a center fielder.

"Thomas and McCarthy get sort of asked [about] as an either or, but teams definitely have one over the other in some cases," Hazen said. "A lot of teams say they like them both but then tell us they like one maybe a little ahead of the other, and that's split 50-50."

When it comes to the rotation, the Diamondbacks finished last year with six starters in Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Brandon Pfaadt, Ryne Nelson and Jordan Montgomery.

There is clearly a need for starting pitching throughout the game given some of the free agent contracts that have been handed out so far this winter. Hazen has told teams he's not trading Gallen or Kelly, but it is assumed that Arizona would part with Montgomery, who struggled last season and exercised his $23.5 million contract option for 2025.

Given that the Diamondbacks went to the World Series in 2023 and actually won more games in '24 (89) but missed the playoffs due to losing tiebreakers with both the Mets and Braves, Hazen would prefer not to lose any pieces off his Major League team.

But, with three Wild Cards in each league, more and more teams believe they are contenders for the postseason and want to trade for Major League players as opposed to prospects.

"I don't really want to trade the center field depth or the starting pitching depth, honestly," Hazen said. "Competitive teams just don't want Minor League players for the most part. They want Major League for Major League is where a lot of the deals are settling down. Unless we can match up with a team that is just focused on prospects, but there's not that many of those teams and we haven't really matched up [with them] in a lot of cases so far."

Hazen has made it clear that with the Diamondbacks' window of contention open, he would be willing to trade a player with more controllable years remaining than the player he would get back.

But again, it takes two teams to match up and so far it hasn't happened.

The nice part for Hazen is that he doesn't have a lot of holes to fill so there is not a rush. In years past when he's had to rebuild an entire bullpen there was more urgency.

"When you're targeting maybe two guys to add into the mix it takes a little while longer just to add the guy that's the best fit," he said. "We're pursuing things on the trade market and the free agent market [and] trying to weigh what the cost is going to be for everything and how we're going to pull it off."
