MLB Player News

The Tigers acquired Mayfield and left-hander Jackson Wolf from the Padres on Monday in exchange for right-hander Casey Mize and infielder Gage Workman, Kevin Acee of The San Diego Union-Tribune reports.

Mayfield, 21, sits in the low-90s with his fastball, but the rest of his arsenal is mid-rotation caliber, headlined by a plus changeup. The 6-foot-4 southpaw posted a 3.54 ERA, 1.16 WHIP and 62 strikeouts in 53.1 innings across 15 starts at High-A Fort Wayne this season.

The Twins traded Hill, John Klein, Dameury Pena and $250K in international cap space to the Blue Jays on Monday in exchange for Jeff Hoffman, Ben Nicholson-Smith of Sportsnet.ca reports.

The Jays have a history of chasing high-upside prep lefties, selecting Johnny King, Ricky Tiedemann and Brandon Barriera in recent drafts, and Hill is cut from the same cloth. The 6-foot-5 southpaw was given an aggressive assignment to High-A for his age-20 season and while he has missed plenty of bats (35.8 K%), Hill's control has been a problem (17.2 BB%). He has a 5.80 ERA, 1.73 WHIP and 77:37 K:BB in 45 innings across 16 starts.

The Guardians acquired Griffin from Washington on Monday, Jeff Passan of ESPN.com reports.

The Guardians acquire Griffin, a starting pitching rental on an expiring contract after the 2026 season. Griffin, who made his first All-Star game this season, will join the Guardians as they bolster their starting rotation. The 30-year-old is tied for fourth in the majors with 12 wins, owning a 3.06 ERA, 1.07 WHIP and 116:30 K:BB through 129.1 innings. The left-hander will join a staff consisting of Gavin Williams, Parker Messick, Joey Cantillo and Tanner Bibee.

The Orioles acquired Forret from the Rays on Monday in exchange for right-hander Tyler Wells, Jake Rill of MLB.com reports.

Forret makes his way back to Baltimore after being drafted by the Orioles back in 2023. The 22-year-old was dealt to Tampa Bay over the offseason along with three other prospects in the trade that sent Shane Baz to Baltimore. At Triple-A Durham this season, Forret posted a 4.89 ERA, 1.47 WHIP and 46:18 K:BB through 38.2 innings. The young right-hander will most likely join Triple-A Norfolk in his return to the Orioles organization.

Yankees manager Aaron Boone said Monday that Schmidt (elbow) is eyeing a return from the 60-day injured list in September, David Lennon of Newsday reports.

Schmidt, who is working his way back from the internal brace surgery he underwent July 11, 2025, resumed facing hitters shortly after the All-Star break and has built up to throwing 45 pitches in live sessions. Per Meredith Marakovits of YES Network, Schmidt will throw his next live BP on Tuesday, and he could head out on an extended rehab assignment soon thereafter. The Yankees will likely have Schmidt get stretched out as a starter while he's out on the farm, but he may represent more of an insurance policy for the rotation. The Yankees will have six high-quality starters once Carlos Rodon (elbow) returns from the injured list later this month, so barring an injury to another member of the rotation, Schmidt could be ticketed for a multi-inning relief role once he's activated.

The Blue Jays acquired Arrighetti (foot) from the Astros on Monday in exchange for outfielder Daulton Varsho and cash considerations.

Arrighetti is currently on the shelf while he recovers from right foot nerve irritation, though he threw in the bullpen Sunday and and could be ready for activation by mid-to-late August, per MLB.com. The righty logged a 1.34 ERA in his first eight starts this season but had stumbled with an 8.34 ERA in his last nine outings prior to landing on the injured list. Arrighetti has a career 24.6 percent strikeout rate at the big-league level, though that impressive mark has also come with an 11.5 percent walk rate.

The Orioles acquired Witherspoon, right-hander Anthony Eyanson, 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.

A first-round draft pick in 2025, Witherspoon had been regarded as one of the top lower-level arms in Boston's farm system, even despite his uneven results during his first season of pro ball. The 21-year-old righty turned in a 4.78 ERA, 1.39 WHIP and 78:34 K:BB while surrendering 10 home runs over 75.1 innings at High-A Greenville. The 6-foot-2, 205-pound Witherspoon is regarded as a good athlete with a deep arsenal that includes multiple pitches with plus potential, making him an intriguing developmental prospect for the Orioles. He's expected to report to High-A Frederick to kick off his time in the Baltimore organization.

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 Blue Jays acquired Stephan and Josh Smith from the Rangers on Monday in exchange for Adam Macko, Ken Rosenthal of The Athletic reports.

Stephan has made 19 starts and two relief appearances for Triple-A Round Rock in 2026, collecting a 5.44 ERA and 97:31 K:BB over 101 frames. The 24-year-old will likely join the rotation at Triple-A Buffalo.
