MLB Trade Deadline Day: Rays Land Freddy Peralta, White Sox Get Luis Castillo as Deals Pile Up Before the 6 P.M. Cutoff
Major League Baseball’s 2026 trade deadline hits its 6 p.m. ET cutoff on Monday, August 3, capping a weekend that opened with the Dodgers’ blockbuster acquisition of Tarik Skubal and has since produced a steady stream of additional deals as contending teams scramble to reshape their rosters for the stretch run.
Setting the Stage
This year’s deadline landed later than usual — Monday instead of the more typical July 31 or August 1 — after MLB set the date to avoid the possibility of a player being traded mid-game, since every game on August 3 starts at 6:40 p.m. ET or later. According to CBS Sports, muddled standings across nearly every division and both wild-card races have turned this year’s deadline into what one analyst called a “seller’s paradise,” with an unusually large number of teams uncertain whether they’re genuine playoff contenders heading into the season’s final two months.
Saturday night’s trade sending two-time reigning AL Cy Young winner Tarik Skubal from the Detroit Tigers to the Los Angeles Dodgers set the tone for the weekend, and rival executives told ESPN that deal effectively opened the floodgates for the pitching-starved teams still shopping.
The Rays Make Their Move: Freddy Peralta
The next major domino fell Sunday, when the Tampa Bay Rays acquired right-hander Freddy Peralta from the New York Mets in exchange for a three-prospect package: outfielder Aidan Smith, right-hander Gary Gill Hill, and second baseman Émilien Pitre, according to Baseball America.
The move reflects the Rays’ strong position in the American League East. Tampa Bay entered Sunday holding the best record in the American League at 65-45, with a 3.5-game lead over the Yankees in the division race. Baseball America noted the Rays were dealing from a position of organizational depth, with their farm system ranked second in the sport’s midseason rankings; Smith, the headline piece going back to New York, was the highest-rated of the three prospects sent to the Mets, ranking 15th in Tampa Bay’s system.
The White Sox Add a Veteran Arm: Luis Castillo
The Chicago White Sox also made a notable pitching addition, acquiring right-hander Luis Castillo from the Seattle Mariners. According to Yahoo Sports’ trade tracker, Seattle received relief pitcher Seranthony Domínguez, outfielder Nolan Jones, and catcher Boston Smith in return.
The move comes after ESPN reported that multiple teams had been engaging Seattle on its starting pitching this deadline season, with the Mariners fielding interest in Castillo as well as fellow starters George Kirby and Emerson Hancock as the club weighed how aggressively to sell.
More Deals Across the League
Several additional trades were finalized as the deadline approached, according to tracking from MLB.com, Yahoo Sports, and MLB Trade Rumors:
- Cubs acquire Kevin Gausman from the Toronto Blue Jays, sending outfielder Brett Bateman and infielder Ty Southisene to Toronto. The Blue Jays also received right-hander Jameson Taillon and cash considerations from the Cubs as part of a separate piece of the deal, with Toronto sending back a player to be named later or cash.
- Yankees acquire infielder Luis García Jr. from the Washington Nationals, sending right-handers Yovanny Cruz, Jake Bird, Jack Cebert, and Ben Grable to Washington.
- Braves acquire right-hander Taylor Mahle from the San Francisco Giants for right-hander Anthony Molina, according to sources cited by MLB.com.
- Braves also acquired outfielder Lane Thomas and left-hander Bailey Falter from the Kansas City Royals, sending right-handers Lucas Braun and Carter Holton to Kansas City.
ESPN noted that Gausman’s trade market had been somewhat limited heading into the weekend because he can block trades to eight teams under his contract — the Athletics, White Sox, Reds, Tigers, Brewers, Mets, Pirates, and Mariners — and because, with plenty of cheaper and more controllable pitching still on the board, any acquiring team would need to absorb roughly $7.5 million of his remaining 2026 salary rather than expecting Toronto to pay it down.
Teams Still Weighing Their Options
As the deadline approached, ESPN reported that the New York Mets were still fielding interest in reliever Clay Holmes, and that the Milwaukee Brewers, Chicago Cubs, Atlanta Braves, New York Yankees, Tampa Bay Rays, and Philadelphia Phillies were all considered possible aggressive buyers looking to bolster their World Series chances against a Dodgers team newly fortified by the Skubal addition.
CBS Sports also raised the Boston Red Sox as a team to watch, noting that a 15-game winning streak had turned Boston from an uncertain roster into buyers looking to add before the deadline closed.
FAQ
When is the 2026 MLB trade deadline? Monday, August 3, 2026, at 6 p.m. ET — later than the typical July 31 deadline, set specifically to avoid a trade occurring during a live game.
What did the Rays give up for Freddy Peralta? The Rays sent outfielder Aidan Smith, right-hander Gary Gill Hill, and second baseman Émilien Pitre to the Mets.
What did the White Sox give up for Luis Castillo? The White Sox sent reliever Seranthony Domínguez, outfielder Nolan Jones, and catcher Boston Smith to the Mariners.
Why was Kevin Gausman’s trade market limited? Gausman’s contract allows him to block trades to eight specific teams, and with $7.5 million of his 2026 salary still owed, any acquiring team needed to absorb that cost rather than expecting a salary paydown from Toronto.
Which teams were still expected to be active as the deadline closed? ESPN and CBS Sports flagged the Mets (shopping Clay Holmes), along with the Brewers, Cubs, Braves, Yankees, Rays, Phillies, and a surging Red Sox team as clubs still positioned to make additional moves before 6 p.m. ET.
Conclusion
What started with the Dodgers’ seismic Skubal acquisition Saturday night turned into one of the more active deadline weekends in recent memory, with the Rays and White Sox both landing frontline starting pitching and several more clubs reshaping their rosters in smaller but still meaningful deals. With the market still moving right up to Monday’s 6 p.m. cutoff, the final hours are likely to produce a few more surprises before the postseason picture fully comes into focus.
