MLB Trade Rumors

The Mariners are reportedly seeking corner infield and bullpen help as the deadline approaches, and MLB.com’s Daniel Kramer reported recently that ownership has signaled it will approve a payroll increase to facilitate such transactions. Adam Jude of the Seattle Times hears similarly, writing that Mariners ownership will authorize increased spending for the front office to add to the roster while ticking through some potential options.

Both Ryan O’Hearn of the Orioles and Josh Naylor of the D-backs are viewed as likely trade candidates over the next month. Both would fit the Mariners nicely at first base, allowing Luke Raley to spend more time in the outfield, where he’s more comfortable than at first base. However, early asking prices from both Baltimore and Arizona are quite high, per Jude.

O’Hearn has repeatedly elevated his game in recent seasons and now stands as one of the most productive hitters in the American League. He’s currently sitting on a .295/.383/.471 batting line with 11 homers, 10 doubles, an 11% walk rate and just a 16.3% strikeout rate through 282 plate appearances. He had a tough month in June, but since being traded from Kansas City to Baltimore in the 2022-23 offseason, O’Hearn has proven himself to be a credible middle-of-the-order bat. He hasn’t quite sustained last year’s enormous gains in contact rate, but he’s chasing off the plate at a career-low rate, walking more and showing a bit more power than he did in 2024.

Naylor offers a similar, albeit not identical skill set. Last year’s career-high 31 homers are far more than O’Hearn has ever produced, though some of that is a simple function of playing time. Naylor logged 633 plate appearances in 2024 (a career-high); O’Hearn has never topped last year’s 494 trips to the plate. Both have above-average power with far better contact skills than the prototypical first baseman/designated hitter. Naylor has fanned only 13% of the time he’s come to the plate in 2025. His 8% walk rate is a bit below average, but his overall .304/.359/.474 slash is terrific.

Looking strictly at 2025, O’Hearn has been a bit more impactful in the batter’s box, but the pair’s last three seasons are virtually identical. Naylor has slashed .279/.340/.472 in 1452 plate appearances, while O’Hearn has turned in a .280/.342/.455 line in 1144 plate appearances. They’ve both walked in 8% of their plate appearances. On a rate basis, Naylor has shown a slight bit more power (.193 ISO to .175), but the difference is minimal. The two are compensated similarly, but Naylor is paid a bit more: $10.9MM to O’Hearn’s $8MM. Both are free agents at season’s end.

In a more interesting but also far less plausible scenario, Jude further reports that the Mariners would have interest if the Red Sox were to make Alex Bregman available. That perhaps speaks to ownership’s willingness to add to the payroll, although presumably, the M’s would be looking for the Sox to at least help with some of Bregman’s heavily deferred $40MM annual salary.

The idea of a Bregman trade is interesting in theory but hard to envision in practice. Players with opt-out clauses and player options are rarely traded, and the massive scale of Bregman’s annual salary only further muddies his candidacy.

In broad terms, it’s difficult for two clubs to line up on prospect compensation for a player with multiple years remaining on his contract but the ability to opt back into free agency at season’s end. The acquiring team generally views that player as a rental — typically an expensive one, salary-wise. In a best-case scenario, that player will produce for two-plus months and then head back to free agency. In a worst-case scenario, he’ll suffer a major injury or see his performance tank, only to forgo the opt-out chance and stick the new club with an unwanted additional year (or years) of the contract in question. The acquiring team will understandably try to price that downside into the prospect return, making it difficult for the two parties to align.

On top of the difficulties surrounding Bregman’s salary and opt-out provision, he’s also been away from the field for more than a month. The Red Sox placed Bregman on the 10-day injured list with a strained quadriceps back on May 24. It was clear at the time that he was facing a lengthy absence. Bregman is inching closer to a return and could be back prior to the All-Star break, but an injury absence of nearly two months and a return only about two weeks prior to the trade deadline creates some risk (to say nothing of the potential for Bregman to struggle upon his return, which would only raise further questions).

Prior to his injury, Bregman was enjoying one of the finest starts of his entire career. He’s played 51 games and taken 226 plate appearances, turning in a stout .299/.385/.553 batting line with 11 homers and 17 doubles. His 9.7% walk rate is up three percentage points over last year’s career-low mark. Bregman was also striking out at a career-high 18.6% rate, but that’s still several points shy of league-average and the uptick in swing-and-miss was accompanied by major gains in batted-ball quality. The 31-year-old’s 92 mph average exit velocity is vastly higher than the 88.8 mph career mark he carried into the season. Ditto his 10.3% barrel rate (career 5.7% prior to ’25) and 48.1% hard-hit rate (career 37.7% prior to ’25).

Bregman is signed through 2027 on a three-year, $120MM contract. Deferrals bring the present-day annual value down closer to a reported $29MM. He can opt out of the contract both at the end of the current season and after the 2026 season but has spoken openly about his interest in signing a long-term extension that’d keep him in Boston more permanently. That’s not exactly a surprise for a player who entered last offseason seeking a long-term deal worth $200MM or more and wound up pivoting to an opt-out-laden, short-term deal with a lofty AAV once that long-term pact didn’t materialize, however.

Ultimately, while it’s fun to dream on the notion of a major trade involving someone of Bregman’s caliber, the specifics surrounding his contract and health — to say nothing of Boston’s uncertain buy/sell status four weeks out from the deadline — render it more a theoretical discussion than a genuine possibility at this stage.

The Mariners entered the 2025 season with a $146MM payroll — third-highest in franchise history. They’ve already added to that ledger with a surprising May claim of outfielder Leody Taveras, which didn’t pan out as hoped. That claim already showed a willingness from ownership to spend a bit more, however, and it bears mentioning that M’s ownership also green-lit payroll hikes for both the 2024 acquisition of Randy Arozarena and the 2022 acquisition of Luis Castillo (as well as his subsequent extension).
