The Pirates acquired Weaver and cash considerations from the Mets on Monday in exchange for shortstop Sammy Stafura, Jorge Castillo of ESPN.com reports.

Weaver receives a potentially big boost in fantasy value with a move to Pittsburgh, where he could be the favorite to serve as the Pirates' closer. The righty reliever has posted a 1.84 ERA and 45:11 K:BB over 44 innings this season for the Mets. Weaver is under contract for 2027 as well, with a salary of $12.5 million.

The Orioles acquired Azocar, right-handers Anthony Eyanson and Kyson Witherspoon, catcher Carlos Narvaez and a player to be named from the Red Sox on Monday in exchange for catchers Adley Rutschman, Jake Rogers and cash, Jake Rill of MLB.com reports.

Narvaez is the only big-league player headed back to Baltimore in the deal, but the trio of Azocar, Eyanson and Witherspoon -- three of the top prospects in Boston's system -- represents a massive return for Rutschman. A 19-year-old outfielder, Azocar packs a good deal of power into his 6-foot-2, 168-pound frame and has slugged 18 home runs over 399 plate appearances between Single-A Salem and High-A Greenville. He's also chipped in 10 steals in 12 attempts, though he doesn't project to be a major difference-maker in that category by the time he reaches the big leagues.

The Orioles acquired Eyanson, right-hander Kyson Witherspoon, outfielder Enddy Azocar, catcher Carlos Narvaez and a player to be named later from the Red Sox on Monday in exchange for catchers Adley Rutschman, Jake Rogers and cash, Jake Rill of MLB.com reports.

Narvaez is the only big-league player headed back to Baltimore, while the trio of Eyanson, Witherspoon and Azocar were three of the top-rated prospects in the Boston farm system. Eyanson headed into 2026 will limited fanfare, but the 22-year-old righty has shot up prospect lists after displaying an uptick in velocity during his first season of professional ball and elite results to match it. Between 16 appearances (15 starts) at High-A Greenville and Double-A Portland spanning 68.1 innings, Eyanson has submitted a 1.32 ERA, 0.89 WHIP and 26.5 K-BB%. He'll likely report to Double-A Chesapeake with his new organization, and with a strong finish to the campaign, he should set himself up for an early-2027 MLB debut.

Detmers has not been traded to the Cubs, Jesse Rogers of ESPN.com reports.

A previous report indicating that a deal sending Detmers to the Cubs was done, but it turned out to be inaccurate. Detmers remains a prime trade candidate, but it's unclear whether a deal to the Cubs or any other team has momentum. The left-hander has posted a 4.03 ERA and 145:38 K:BB across 125 innings covering 22 outings for the Angels this season.

The Cubs acquired Detmers from the Angels on Monday, Michael Cerami of Bleacher Report reports.

The Cubs previously traded for Kevin Gausman and have further bolstered their rotation with the addition of Detmers, who has logged a 4.03 ERA and 145:38 K:BB across 125 innings covering 22 outings for the Angels this season. The 27-year-old left-hander will be under team control through the end of the 2028 campaign.

The Red Sox acquired Rutschman (wrist), Jake Rogers and cash from the Orioles on Monday in exchange for catcher Carlos Narvaez, right-handers Anthony Eyanson and Kyson Witherspoon, outfielder Enddy Azocar and a player to be named later, Jake Rill of MLB.com reports.

After surging to a 23-3 record over the past 26 games to put itself back in the thick of the playoff race, Boston will shore up one of the few remaining weaknesses on its roster by bringing in a bona fide No. 1 catcher in Rutschman. The 28-year-old backstop has been on the shelf since July 20 due to left wrist inflammation, but he resumed hitting over the weekend and is expected to head out on a rehab assignment during the upcoming week. If all goes well, Rutschman could be ready to make his Boston debut at some point during the team's nine-game, three-city road trip that begins Friday. Before going down with the injury, Rutschman was in the midst of a resurgent 2026 campaign with the Orioles, slashing .251/.331/.433 with eight home runs and a career-low 14.1 percent strikeout rate over 284 plate appearances.

The Rays optioned Cook to Triple-A Durham on Monday.

Cook allowed three runs with a 2:2 K:BB over 3.2 innings in his first two major-league appearances. He's being sent down in order to free up a spot on the active roster for right-hander Freddy Peralta, who was acquired from the Mets on Sunday.

The Giants acquired Mendez (undisclosed) and shortstop Joniel Hernandez from the Padres on Monday in exchange for left-hander Robbie Ray, Alex Pavlovic of NBC Sports Bay Area reports.

San Diego added Mendez to its 40-man roster over the winter, but the 24-year-old righty has yet to pitch above the Double-A level and probably won't be a realistic candidate to make his MLB debut until 2027. Mendez turned in a 4.93 ERA, 1.46 WHIP and 38:17 K:BB in 34.2 innings over 11 starts with Double-A San Antonio this season before landing on the 7-day injured list June 27 due to an unspecified injury. He was cleared to begin a rehab assignment in the Midwest League last week and could soon be ready to come off the IL and report to Double-A Richmond with his new organization.

The Royals acquired Duran from the Dodgers on Monday in exchange for Kris Bubic (elbow/shoulder), Mark Feinsand of MLB.com reports.

Duran has spent the entirety of the 2026 season at Triple-A Oklahoma City, where he's collected a 3.38 ERA and 61:28 K:BB over 42.2 innings. The 25-year-old made one appearance in the majors with the Athletics in 2025, yielding three runs while recording only one out.

The White Sox designated Davitt for assignment Monday.

The move clears a spot on the 40-man roster for outfielder Brenton Doyle, who was acquired from the Rockies on Monday. Davitt has allowed one run over two innings during his brief time in the majors this season and holds a 6.22 ERA and 64:25 K:BB across 59.1 frames at Triple-A Charlotte.
