MLB trade deadline: Analysis for all major moves

Follow along for analysis of all major transactions leading into Thursday's 6 p.m. ET trade deadline.

Blue Jays address bullpen with Domínguez

The Blue Jays only had to look across the field for bullpen help this deadline. Toronto acquired Seranthony Domínguez from the Orioles at the halfway point of a doubleheader in Baltimore. The right-hander is exactly what the club needs; a hard-throwing reliever who misses bats and can pitch in high-leverage moments. Domínguez, who is on an expiring deal, ranks 92nd percentile in strikeout percentage, 94th in fastball velocity, and 95th in whiff rate, per Baseball Savant. Walks are a bit of a concern - Domínguez owns a career-worst 5.2 BB/9 this season - but the trade off is he doesn't allow hard contact, and has only surrendered four home runs in 41 2/3 innings. He'll likely slot in as setup behind closer Jeff Hoffman. This is a good start for Toronto, but they need to add at least another bullpen arm.

Domínguez joins Gregory Soto as the second bullpen departure for the Orioles going into the deadline. It's clear that Mike Elias is targeting young pitching, and Juaron Watts-Brown gives the system another arm. The 23-year-old was the Blue Jays' No. 10 prospect and is enjoying a solid season in Double-A. He was Toronto's third-round pick in 2023.

Brewers beef up catching, Rays buy and sell

It's never a surprise to see the Rays both buying and selling around the deadline. Moments after Tampa Bay shipped impending free-agent catcher Danny Jansen to Milwaukee for the Brewers' No. 24 prospect, Jadher Areinamo, the Rays acquired catcher Nick Fortes from the Marlins. The Brewers have received underwhelming offensive production from backstops William Contreras (6 HR, .682 OPS) and Eric Haase (2 HR, .646 OPS) this season. Jansen's bat should help, as he's hit 11 home runs with a .703 OPS through 73 games. So much has gone well in Milwaukee this season, but the offense lacks thump, sitting 22nd in slugging and 24th in home runs. Jansen doesn't solve all those problems, but he does give the lineup more power against left-handed pitching. Haase was designated for assignment to make room for Jansen.

Fortes gives Tampa Bay a controllable catcher who's arbitration-eligible through 2028. The 28-year-old is far from an offensive force, hitting two home runs to go with a .637 OPS through 59 games this season. He grades highly defensively, however, ranking in the 75th percentile in both framing and pop time. Although the Rays do many things well, finding a franchise catcher isn't one of those things. The club has used 10 different catchers over the last four seasons and they've combined for just 3.5 fWAR, with none playing more than 149 games for the organization.

Tigers add starting depth in Paddack

Chris Paddack immediately slides into the vacancy in Detroit's rotation left by Reese Olson's season-ending injury. Luckily for the Tigers, Olson was injured before the deadline and they were able to patch the hole. Paddack comes at a relatively low cost, giving Detroit another veteran starter after the team relied heavily on "pitching chaos" down the stretch in 2024. The right-hander's struggled of late, posting a 7.49 ERA over his last eight starts. He is, however, coming off a strong last outing at Dodger Stadium in which he allowed one run over six innings while striking out eight. Minnesota saved close to $4 million on the deal when factoring in Randy Dobnak's contract and also added Detroit's No. 14 prospect.

Royals become surprise buyers with Grichuk trade

The Royals made a commitment to field a winning club after signing Bobby Witt Jr. to a long-term extension, and sitting 4.5 games out of a playoff spot, they're clearly not ready to wave the white flag. Acquiring Randal Grichuk isn't an all-in move, but he'll be a welcome addition to an outfield devoid of power - his career .825 OPS against left-handed pitching should boost the offense. The trade for Grichuk was quickly followed by an extension for Seth Lugo. The right-hander was believed to be one of the better starting pitchers on the trade market, but Kansas City clearly saw more value in keeping him. Meanwhile, Andrew Hoffmann and Brandyn Garcia (acquired in the Josh Naylor trade) give the Diamondbacks two relievers who have already pitched in the majors.

Yankees solidify 3B with McMahon

The Yankees landed a third baseman from the NL West; it just wasn't the one many fans were hoping for. Ryan McMahon isn't the same kind of impact bat as Eugenio Suárez, but he's arguably a better fit for New York. The club's been abysmal defensively, and McMahon brings a strong glove at the hot corner and is under team control through 2027 (owed $16 million in each of the next two seasons). McMahon also adds plenty of pop (16 home runs), but it comes with a lot of strikeouts (32 K%). While his career numbers away from Coors Field (.589 road OPS) will raise some eyebrows, he hits the ball hard and draws walks, so his production should even out. Considering the limited market for quality third basemen, the Yankees did fine to add McMahon, even if his salary is high compared to his overall value. The two prospects general manager Brian Cashman traded for him haven't pitched above A-ball.

Rosario joins Yankees as bench depth

Amed Rosario is another floor-raiser for the Yankees, who continue to get limited production from their young infielders. The No. 5 prospect in baseball in 2017, Rosario never developed into a star. However, the 29-year-old is a serviceable vet who's played second base, third base, shortstop, and right field over the last two seasons while posting an .816 OPS against left-handed pitching. Rosario isn't a great defender, but he seldom strikes out. He brings plenty of value in a utility bench role. Clayton Beeter is an intriguing relief arm for the Nationals. The 26-year-old owns a 14.6 K/9 over 24 2/3 innings in the minors this season.

Mets bring in Soto as lefty help in 'pen

Gregory Soto's on the move for a second straight trade deadline. The two-time All-Star remains an effective reliever, boasting strong strikeout numbers (10.8 K/9) though he can struggle with his command at times (4.3 BB/9). The Mets needed another southpaw reliever, and Soto was especially tough on left-handed hitters for the Orioles this season, holding them to a .133/.264/.267 slash line in 72 plate appearances. While Wellington Aracena hasn't pitched above A-ball, Cameron Foster could potentially feature in Baltimore's bullpen down the stretch. He put up strong numbers in Double-A this season, albeit at 26 years old.

Mariners add impact bat in Naylor trade

There were few more perfect fits this deadline than Josh Naylor landing in Seattle, where first base has been a significant hole for much of the season. Not only does Naylor give the Mariners a power bat, but he doesn't strike out - and that's been a major problem for their offense in recent years. A middle of the order with Julio Rodríguez, Cal Raleigh, Naylor, and Randy Arozarena is pretty imposing. For Arizona, trading Naylor is the first step in what's expected to be a sell-off leading into the trade deadline. Expect the D-Backs to ship out anyone on an expiring deal in an attempt to retool heading into 2026.
