Orioles deal former top prospect for Halos power bat

It’s hot stove season! The 2025-26 MLB offseason is officially here, and we have you covered with grades and analysis for every major signing and trade this winter.

Whether it’s a big-money free agent signing that changes the course of your team’s future or a blockbuster trade, we’ll weigh in with what it all means for next season and beyond.

ESPN MLB experts Bradford Doolittle and David Schoenfield will evaluate each move as it happens, so follow along here — this story will continue to be updated. Check back in for the freshest analysis through the start of spring training.

One thing that is head-scratching here: The Mets are pretty deep in high-quality infield prospects, from Luisangel Acuna to Ronny Mauricio to Jett Williams, all of whom carry considerably more upside than Semien at this point.

We’ll see how that shakes out as the offseason unfolds, but for now, we can focus on Nimmo’s bat and the possibility that his numbers could get a bump from the switch in venues. He’s typically hit better on the road than at pitcher-friendly Citi Field, and Globe Life Field, while strangely stingy overall last season, has typically been a solid place to hit for left-handed batters.

The first major trade of last offseason came on Nov. 22, when Cincinnati dealt Jonathan India to Kansas City for Brady Singer. This one leaked on Nov. 18, so we’re getting an earlier start. Given the relatively tepid nature of this year’s free agent class, the hope is that this deal is the vanguard of a coming baseball swap meet. Trades are fun.

Ward turns 32 next month, likely putting him at the outer rim of his career prime. He has been a decent player — an average of 3.0 bWAR over the past four years — but his skill set is narrow. Ward has been a fixture in left field the past couple of seasons and has shown diminishment both on defense and on the bases. He’s someone you acquire for his bat.

That’s not a bad thing, but that approach, combined with a fly ball-heavy distribution, has led to a consistently plummeting average: .281 to .253 to .246 to .228. He’s a take-and-rake guy who doesn’t generate enough fear from pitchers to keep them out of the zone, which might supercharge his walk rate enough to bring his OBP up to an acceptable level, which it won’t be given the batting average trend.

And all of this would be fine for one year of a productive hitter likely to earn $12-14 million through the arbitration process. But at the cost of four years of a pitcher with Rodriguez’s ceiling? I’m not seeing it.

And the ceiling is very high. ESPN’s Kiley McDaniel ranked Rodriguez as the game’s top pitching prospect in 2022 and rated him nearly as high in 2023. The mere possibility of Gray-Rod (did it again) fulfilling that potential in an Angels uniform is an exciting notion for fans in Anaheim.

The deal opens up a hole in the outfield for the Angels with no obvious plug-in solution from the organization. But finding a free agent replacement who approximates or exceeds Ward’s production shouldn’t break the bank. Here’s a vote for going after Cody Bellinger.

The possibility of that kind of upgrade and maybe someday a fully realized Gray-Rod, all for the low-low price of one season of Taylor Ward? Sign me up. — Doolittle

It’s easy to understand why they wanted Naylor back. The Mariners have been searching for a long-term solution at first base for, oh, going on 20 years — really, since they traded John Olerud in 2004. Ty France gave them a couple solid seasons in 2021 and 2022, but since 2005 only the Pirates’ first basemen have produced a lower OPS than Seattle’s.

He’s not a star — 3.1 WAR in 2025 was a career high — but he’s a safe, predictable player to bank on for the next few years. This deal runs through his age-33 season, so maybe there’s some risk at the end of the contract, but for a team with World Series aspirations in 2026, the Mariners needed to bring Naylor back. The front office will be happy with this signing and so will Mariners fans. — David Schoenfield

One-for-one swaps of quality veterans are rare enough these days that when one lands, and people are familiar with both players, the label “blockbuster” starts to get thrown around in a way that would make Frantic Frank Lane roll his eyes. This deal, which brings Semien to New York for career Met Nimmo, is interesting. It is also a trade involving two post-30 players carrying multiple seasons of pricey contracts. Lackluster would be a better description than blockbuster. The valuations on this deal at Baseball Trade Values illustrate nicely the underwater contracts involved.

For the Mets, it’s important to underscore the fact that Semien is 35 years old. Though he challenged for AL MVP during Texas’ championship season in 2023, his offensive numbers have since headed south, as tends to happen to middle infielders with his expanding chronology. Over the past two seasons, his bat has been just below league average — and while there is plenty of value in being roughly average, it’s still a precarious baseline for a player on the downside of his career. His offensive forecast isn’t as good as that of New York’s heretofore presumed regular at second base, Jeff McNeil, who might still get plenty of run at other positions.

If you ignore positional adjustments, Nimmo is a better hitter than Semien and should be a considerable upgrade for Texas in the outfield compared with what the Rangers had been getting from the recently non-tendered Adolis Garcia. He’s not as good a defender as Garcia, especially in arm strength and, in fact, is likelier to play in left in Texas rather than Garcia’s old spot in right. As mentioned, Semien was a Gold Glover at his position and so now, in their effort to remake an offense that needed an overhaul, you worry that the Rangers are putting a dent in their defense.

If there was an award for free agent prediction most to likely come true, Josh Naylor returning to the Seattle Mariners would have been the front-runner, so it’s hardly a surprise that this is the first significant signing of the offseason (pending a physical). As soon as the Mariners’ season ended with that heartbreaking loss in Game 7 of the ALCS, the front office made it clear that re-signing Naylor was its top priority. Such public vocalizations at that level are rare — and the Mariners backed them up with a five-year contract.
