MLB Player News

Leiter (leg) threw a live batting practice session Thursday, Jorge Castillo of ESPN.com reports.

It appears to be the first time he's faced hitters since landing on the 15-day injured list in early July with a left fibular head stress fracture. Per Yankees manager Aaron Boone, Leiter could be ready to rejoin the bullpen during the team's series early next week in Texas.

The Athletics acquired Nunez, shortstop Leo De Vries, right-hander Braden Nett and right-hander Henry Baez from the Padres on Thursday in exchange for right-hander Mason Miller and left-hander JP Sears, Jeff Passan of ESPN.com reports.

Of the four players acquired by the Athletics, Nunez has the closest proximity to the big leagues. He had occupied a spot on the Padres' 40-man roster and made his MLB debut earlier in July, making four relief appearances for San Diego before being demoted shortly before the All-Star break. He had otherwise spent the entire 2025 season in the minors and compiled a 2.06 ERA and 1.03 WHIP while striking out 56 batters over 35 innings between Double-A San Antonio and Triple-A El Paso. Even if the Athletics opt to have Nunez begin his time in the organization at Triple-A Las Vegas, the right-hander likely won't have to wait long to earn a look in the big-league bullpen.

Thaiss is out of the lineup for Thursday's game against the Yankees, Marc Topkin of the Tampa Bay Times reports.

Though the Rays recently shipped catcher Danny Jansen to Milwaukee while acquiring another backstop in Nick Fortes from Miami, Thaiss' playing-time outlook is unlikely to change dramatically. Thaiss had started in three of the previous four contests, but he's still likely to be stuck in a timeshare behind the dish with Fortes, who is regarded as the superior defender of the two.

Baez was traded rom the Padres to the Athletics on Thursday along with Leo De Vries, Braden Nett and Eduarniel Nunez in exchange for Mason Miller and JP Sears, Jeff Passan of ESPN.com reports.

Baez is already on the 40-man roster and has never pitched above Double-A, but he has a chance to be a back-end starter for the Athletics as early as next year. The 22-year-old righty has a 1.96 ERA, 1.00 WHIP and 89:31 K:BB in 96.2 innings across 20 starts at Double-A this year. Baez doesn't have any plus pitches, and he may not even have any above-average pitches, so his fantasy upside is limited.

Mangum is out of the lineup for Thursday's game against the Yankees, Marc Topkin of the Tampa Bay Times reports.

Mangum will cede his spot in the outfield to Jonny DeLuca, who will cover center field while Chandler Simpson shifts over to left field. Since the All-Star break, Mangum has started in nine of the Rays' 13 contests while slashing just .147/.194/.176 with two stolen bases, two runs and zero RBI.

Nett was traded rom the Padres to the Athletics on Thursday along with Leo De Vries, Henry Baez and Eduarniel Nunez in exchange for Mason Miller and JP Sears, Jeff Passan of ESPN.com reports.

Nett has power stuff and has always missed bats at a high clip, but his control has typically been shaky. He had his best stretch as a pro in May and June, when he logged a 1.94 ERA, 1.15 WHIP and 49:14 K:BB in 41.2 innings, although he walked nine in 10 innings over his next three starts. The 23-year-old righty has logged 18 total starts at Double-A in his career, so he could get a taste of Triple-A before the end of the year. If Nett is able to limit the walks, he could spend time next year in the Athletics' rotation.

The Rays recalled Rock from Triple-A Durham on Thursday.

Rock made one relief appearance for the Rays earlier this season, allowing two runs over two innings. The lefty has been used primarily as a starter in the minors, so he can give the bullpen some length.

The Rays recalled Seymour from Triple-A Durham on Thursday.

Tampa Bay had optioned the lefty to Durham on Wednesday, but Seymour will rejoin the big club just one day later to take over the 26-man active roster spot that had belonged to right-hander Zack Littell, who was traded to the Reds. Seymour has worked exclusively in relief over his seven appearances with the Rays, but he's made 15 starts at Triple-A this season and could be an option to join the big-league rotation if Tampa Bay isn't yet ready to call right-hander Taj Bradley back up from Durham to replace Littell.

De Vries was traded from the Padres to the Athletics on Thursday along with three pitchers from San Diego in exchange for Mason Miller and JP Sears, Jeff Passan of ESPN.com reports.

De Vries is one of baseball's top prospects, but he is over a year away from the major leagues. He isn't a lock to stick at shortstop, and now that he is in the same organization as Jacob Wilson (forearm), it's safe to assume De Vries will end up at second base long term. De Vries has slashed .245/.357/.410 with eight home runs, eight steals, a 14.1 percent walk rate and a 19.6 percent strikeout in 82 games as the youngest player at High-A.

The Orioles recalled Young from Double-A Chesapeake on Thursday.

Baltimore returned Young to the minors Wednesday, one day after he made a six-inning spot start as the 27th man for Tuesday's doubleheader with the Blue Jays. Despite turning in a quality start, Young still holds a 6.63 ERA and 1.69 WHIP in 36.2 innings in the majors this season, but he could nonetheless be in line for additional turns through the Baltimore rotation after he was recalled from Double-A to replace Zach Eflin (back), who was placed on the 15-day injured list in a corresponding move. Eflin's next start was scheduled to come up either Sunday versus the Cubs or Monday versus the Phillies, and the Orioles could look to either Young or rehabbing left-hander Cade Povich (hip) to fill in for the righty.
