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.

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 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.

The Orioles placed Eflin on the 15-day injured list Thursday due to low-back discomfort.

Eflin will hit the shelf for the third time this season and for the second time in just over a month due to continued back problems. After being reinstated last week, Eflin made just two starts for the Orioles before suffering an apparent setback. Baltimore recalled right-hander Brandon Young from Double-A Chesapeake in a corresponding move, and he or the rehabbing Cade Povich (hip) could be called upon to replace Eflin in the rotation the next time his turn comes up.

Matthews (2-3) took the loss in Wednesday's 13-1 rout at the hands of the Red Sox, coughing up five runs on eight hits over 4.1 innings. He struck out four without walking a batter.

The 25-year-old right-hander once again showed great control without much command in the zone, firing 52 of 74 pitches for strikes but watching half the hits he allowed go for extra bases, including a solo shot by Trevor Story in the second inning. Matthews has an impressive 17:1 K:BB over three starts and 14.1 innings since the All-Star break, but it comes with a 6.28 ERA that isn't just a product of bad luck. He'll try to tighten things up in his next outing, which is scheduled to come on the road early next week in Detroit.

The Orioles are expected to place Eflin on the 15-day injured list Thursday, Ken Rosenthal of The Athletic reports.

The report doesn't specify what kind of injury Eflin is dealing with, but he just returned from a back issue last week after missing nearly a month of action. Rosenthal relays that it's "very possible" Eflin is still traded ahead of Thursday's deadline even though he's hurt, as he is expected to be back before the end of the season. The veteran righty holds a 5.93 ERA, 1.42 WHIP and 50:13 K:BB across 71.1 innings this season.

Bello (7-5) picked up the win in Wednesday's 13-1 rout of the Twins, allowing one run on five hits and four walks over seven innings. He struck out four.

While his control wasn't particularly sharp, the only real blemish on Bello's line was a solo shot by Matt Wallner in the second inning. The right-hander fired his fourth quality start in his last five trips to the mound, and he hasn't been tagged for more than three earned runs since May 18, posting a 2.83 ERA, 1.09 WHIP and 54:19 K:BB over 70 innings since the beginning of June. Bello will look to keep rolling in his next outing, which lines up to come at home early next week against the Royals.

Paddack (4-9) picked up the win in Wednesday's 7-2 victory over the Diamondbacks, allowing one run on three hits over six innings. He struck out five without walking a batter.

The right-hander celebrated being dealt to a Tigers team in the thick of the race for the best record in the AL by delivering his sixth quality start of the season on 84 pitches (58 strikes) in his debut for his new squad. Paddack has had an uneven campaign, posting a 4.77 ERA, 1.24 WHIP and 88:27 K:BB through 117 innings, but simply being able to take a regular turn in the rotation has to count as a successful season -- that innings total is his highest since 2019. He'll look to build on this performance in his next outing, which is scheduled to come at home early next week against the Twins team that just traded him away.

The Tigers designated Manning for assignment Thursday, Evan Petzold of the Detroit Free Press reports.

Once a heralded starting pitching prospect in the organization, Manning struggled to stay healthy over each of the previous three seasons and was unable to establish himself as a permanent part of the big-league rotation. Though Manning had still managed to produce a 3.74 ERA in 168.2 innings in the majors from 2022 through 2024, the Tigers elected to move him to the bullpen earlier this season after he failed to win a spot on Detroit's Opening Day roster. While Manning has been able to stay healthy at Triple-A Toledo in 2025, his stuff hasn't played up in the bullpen as the Tigers had hoped. He had yet to receive a call-up this season while compiling a 6.04 ERA, 1.63 WHIP and 52:37 K:BB in 50.2 innings with Toledo, and the Tigers have now elected to move him off the 40-man roster in order to open up a spot for trade-deadline pickup Paul Sewald (shoulder). Given his pedigree, the 27-year-old Manning could attract interest via waivers, but he doesn't look to be especially close to being an impact arm in the majors.

Kremer didn't factor into the decision in Wednesday's 9-8 loss to the Blue Jays, giving up three runs on six hits and two walks over five innings. He struck out five.

The right-hander was surprisingly taken deep by Myles Straw for a two-run homer in the second inning, but otherwise Kremer was fairly effective over his 87 pitches (56 strikes). He's allowed three runs or fewer in six of his last eight starts, posting a 3.06 ERA, 1.09 WHIP and 43:13 K:BB through 47 innings over that stretch. He faces another tough test in his next outing, which is scheduled to come on the road early next week in Philadelphia.
