The Padres announced that they have selected right-handers Garrett Hawkins and Miguel Mendez to their 40-man roster. That protects both of them from being selected in next month’s Rule 5 draft. San Diego’s 40-man roster count climbs to 36.

The Orioles have designated outfielder Pedro Leon and infielder Luis Vazquez for assignment, per a team announcement. Their roster spots go to right-hander Cameron Foster and outfielder Reed Trimble, who have been selected to the 40-man roster and are now protected from being poached in December’s Rule 5 Draft.
Once a high-profile international signing by the Astros, Leon originally received a $4MM signing bonus from Houston. He ranked as one of the Astros’ top prospects for several seasons but has stalled out in the upper minors and landed with the O’s by way of waiver claim earlier this offseason. He’s just 2-for-20 in seven big league games and has a .252/.354/.447 batting line in parts of five Triple-A seasons. Leon still runs well, but he’ll be 28 next May and has yet to make a big impact in Triple-A, let alone in the majors.

The Tigers designated six relief pitchers for assignment: Dugan Darnell, Jack Little, Sean Guenther, Jason Foley, Tanner Rainey and Tyler Mattison. They added five prospects to the roster to keep them out of the Rule 5 draft: Hao-Yu Lee, Thayron Liranzo, Trei Cruz, Eduardo Valencia and Jake Miller. The sixth roster spot is filled by Gleyber Torres, who officially accepted the qualifying offer.
Cruz gets a 40-man spot for the first time going into his age-27 season. The Tigers had left the former third-round pick unprotected in the past two offseasons. The switch-hitting infielder, the son of former big league outfielder José Cruz, earned his way onto the roster with a breakout year in the upper minors. Cruz hit .279/.411/.456 while leading all minor league hitters with 102 walks between the top two levels. The Rice product can play both left side infield positions and has the athleticism to play some center field.
Valencia is a 25-year-old catcher/first baseman who posted a monster .311/.382/.559 slash line between Double-A Erie and Triple-A Toledo. He blasted 24 home runs while keeping his strikeout rate around 20%. The Venezuela native has never been viewed as much of a prospect, but the offensive performance in the high minors was too much to ignore.
Miller, a 24-year-old lefty, ranked 16th in the Detroit system at MLB Pipeline. An eighth-round pick in 2022 out of Valparaiso, he has shown an intriguing three-pitch mix with enough command and deception to project as a starter. Miller was limited to six starts between High-A and Double-A this year by a back injury, but Detroit likes him enough to keep him as a developmental play. He should begin next season in Erie.

The Blue Jays have selected the contract of top pitching prospect Ricky Tiedemann, per a club announcement. They’re now up to 38 players on the 40-man roster.
Tiedemann, 23, didn’t pitch this past season while recovering from Tommy John surgery performed in July 2024. Be that as it may, given how highly regarded the 2021 third-rounder had become prior to that injury, he’d surely have been scooped up by a non-contending club in next month’s Rule 5 Draft.
Though Tiedemann still hasn’t topped the 78 2/3 innings he pitched in his first full professional season back in 2022, he ranked among the game’s top 100 prospects at Baseball America in each of the past three offseasons. He’s pitched to a career 3.02 ERA in the minors and fanned a gargantuan 39.6% of his opponents. His 11.9% walk rate clearly needs refinement, but the 6’4″, 220-pound Tiedemann carries substantial upside as a potential playoff-caliber starter or a late-game reliever with possibly elite bat-missing abilities.

The Pirates announced that they have designated four players for assignment. That list includes outfielders Alexander Canario and Ronny Simón, as well as right-handers Colin Holderman and Dauri Moreta. Additionally, Cam Devanney was released to pursue opportunities overseas. It was reported a few days ago that Devanney would be signing with the Hanshin Tigers of Japan’s Nippon Professional Baseball.
The Bucs already had one open 40-man spot and those moves opened five more. That allowed them to select six players to the roster ahead of today’s Rule 5 deadline. Those six are first baseman/outfielder Esmerlyn Valdez, infielder Jack Brannigan, left-hander Tyler Samaniego and right-handers Wilber Dotel, Antwone Kelly and Brandan Bidois.
José Negron of DK Pittsburgh Sports reported the Valdez move prior to the official announcement. Alex Stumpf of MLB.com reported the other five additions. Jason Mackey of the Pittsburgh Post-Gazette reported the guys being designated for assignment.

The White Sox announced that they have selected right-handed pitchers Duncan Davitt and Tanner McDougal to their 40-man roster. That protects both of them from being selected in the Rule 5 draft. The Sox also noted that left-hander Fraser Ellard has been placed on the voluntarily retired list.

The Marlins selected catcher Joe Mack and right-handers Will Kempner and Josh White onto the 40-man roster to keep them out of the Rule 5 draft. Miami designated outfielder Joey Wiemer for assignment in a corresponding move, as they’d previously had two vacancies.
Mack is one of the more obvious names to keep away from the Rule 5 draft. A supplemental first-round pick out of high school in 2021, he has developed into one of the better all-around catching prospects in the majors. The left-handed hitter connected on 21 homers with a .257/.338/.475 slash line in 468 plate appearances between the top two minor league levels.
Most of that production came in Triple-A. Mack is on the doorstep of the majors and he’s a better defensive catcher than either Liam Hicks or Agustin Ramirez. Mack has the best chance of the group to be Miami’s long-term answer behind the plate. It’s not out of the question he breaks camp, and he’ll almost certainly debut at some point next season.
Kempner, 24, was acquired from the Giants for international bonus pool room last offseason. A third-round pick out of Gonzaga in 2022, he’s a pure reliever who turned in a 2.26 ERA across 67 2/3 innings between a trio of levels in his first season in the Miami system. Kempner fanned more than a third of opponents but walked upwards of 14% of batters faced. He sits around 95 MPH and could be an up-and-down reliever next season. The 24-year-old White should also be in that mix after running a monster 40.8% strikeout rate across 67 2/3 frames between the top two levels. The former fifth-round draftee sits in the 93-94 MPH range and leans heavily on a plus mid-80s slider.
Miami claimed Wiemer, a one-time top prospect, off waivers from Kansas City in August. He played in 27 games down the stretch, hitting .236 with a trio of home runs but striking out 23 times in 61 trips to the plate. Wiemer has big physical tools but has been too strikeout prone throughout his career. He’s a .205/.279/.359 hitter in a little under 500 plate appearances. Miami can non-tender him on Friday and try to bring him back on a minor league contract.

The Red Sox are trading left-hander Chris Murphy to the White Sox, reports Bob Nightengale of USA Today. The Red Sox are receiving a catcher in return, per Britt Ghiroli of The Athletic. That catcher is Ronny Hernandez, per Alex Speier of The Boston Globe.
Murphy, 28 in June, made his big league debut as a long reliever with Boston in 2023. He logged 47 2/3 innings over 20 appearances, allowing 4.91 earned runs per nine. His 23.1% strikeout rate, 8% walk rate and 44.7% ground ball rate were all pretty close to league averages. He couldn’t carry that over in 2024, as he required Tommy John surgery in April of that year.
He was on the injured list until midway through the 2025 season. He logged another 34 2/3 innings in the big leagues this year with a 3.12 ERA. His 20.3% strikeout rate was down a bit and his 13.5% walk rate was a notable jump, though perhaps some post-surgery rust was at play. His ground ball rate climbed to 54.3%.
Boston had a bit of a roster crunch today and needed to make some cuts. Both Nathaniel Lowe and Josh Winckowski were designated for assignment today and flipping Murphy also opens up a spot.
For the White Sox, they are rebuilding and have more ability to see if Murphy finds another gear in 2026 and moving forward. He still has an option, meaning they could keep him in the majors or minors or shuttle him back and forth throughout the next season. He came up as a starter, so it’s possible they could try stretching him back out, or they could keep him in a relief role. He has a bit more than two years of service time, meaning he hasn’t yet qualified for arbitration and can still be controlled for another four seasons, maybe even five if he spends a long time on optional assignment.

The Reds announced that they have added three players to the 40-man roster. Infielders Edwin Arroyo and Leo Balcazar had their contracts selected from Double-A Chattanooga, while outfielder Hector Rodriguez was selected from Triple-A Louisville. All three are now protected from the Rule 5 Draft. In addition, right-hander Carson Spiers was designated for assignment. The club’s 40-man roster now stands at an even 40.
Arroyo, 22, was originally a second-round draft pick by the Mariners in 2021. He was one of four prospects who went to Cincinnati in the Luis Castillo trade in July 2022. He spent most of 2023 at High-A but earned a promotion to Double-A in September of that year despite being just 19 years old. However, injury struck in March 2024, as Arroyo suffered a torn labrum in his left shoulder while diving back to the bag on a pickoff attempt. The resulting surgery wiped out his 2024 season. He was a non-roster invite to spring training in 2025 and returned to Double-A Chattanooga for his first full season there, save for a brief stint on the injured list in April for a left hamstring strain.
In 120 games for Chattanooga in 2025, Arroyo batted .284/.345/.371 while scoring 63 runs and chipping in 12 stolen bases. That output was good for a 107 wRC+. Arroyo decreased his strikeout rate to 16.9% in 2025 after sitting at 21.3% across High-A and Double-A in 2023. His walk rate declined from 8.8% to 7.7%, though that is not surprising given the difficulty of the jump to Double-A. MLB.com lists Arroyo as the Reds’ No. 8 prospect and considers him a decent hitter with untapped power potential, though his calling card is his plus defense at shortstop. He figures to spend most 2026 at Triple-A.
Rodriguez, 21, was signed by the Mets as an international free agent in January 2021 and was traded to the Reds in July 2022 in the Tyler Naquin deal. He split the 2025 season between Double-A and Triple-A, batting .298/.357/.481 with a 140 wRC+ in 82 games for Chattanooga. However, Rodriguez hit a wall upon reaching Triple-A, with an 85 wRC+ in 50 games. His walk rate declined to 5.2% after sitting at 8.1% in Double-A. His strikeout rate also increased from 13.9% to 16.5%, although the latter figure is still good and bodes well for his contact ability. The switch-hitter is considered the Reds’ No. 9 prospect and a solid baserunner, though he’ll likely move off of center field for one of the corners long-term.
Balcazar, 21, was signed by the Reds as an international free agent in January 2023 and split the 2025 season between High-A and Double-A. In 75 games at High-A, he posted a 110 wRC+ along with a 14.9% strikeout rate and an 8.5% walk rate. Though his wRC+ declined to 100 in 51 games at Double-A, his strikeout (11.1%) and walk rates (10.6%) both improved over his High-A numbers. MLB.com lists him as the club’s No. 23 prospect. Since his recovery from a torn ACL in 2023, he has proven himself a decent defender at shortstop, though he will continue to get reps at second base as well.
As for Spiers, his DFA was unsurprising given that he underwent elbow surgery in July and was expected to miss most or all of next year. The right-hander was signed as a non-drafted free agent in 2020 and pitched 117 big-league innings with a 5.69 ERA from 2023-25. The bulk of those innings came in 2024, when he made 22 appearances (10 starts) with a 5.46 ERA, a 19.5% strikeout rate, and a 6.6% walk rate. He made just three appearances (two starts) in 2025, all in April, before going on the injured list with a right shoulder impingement on April 20. He was pulled from a rehab assignment in early July with biceps tightness and underwent an MRI, which revealed the more serious UCL damage. It was unclear whether Spiers underwent Tommy John surgery or an internal brace procedure, but the most likely outcome is that he’ll be out until the start of the 2027 season.

The Angels announced Tuesday that they’ve selected the contract of righty Walbert Ureña. He’s now on the 40-man roster and ineligible to be selected by another club in next month’s Rule 5 Draft. His addition bumps the Angels’ 40-man roster count up to 35 players.
Ureña, 21, signed as an amateur out of the Dominican Republic back in 2021 and just split the 2025 season between Anaheim’s Double-A (135 1/3 innings) and Triple-A (5 2/3 innings) affiliates. He pitched to a combined 4.34 ERA in his 141 innings, fanning 20.7% of his opponents against a 12.1% walk rate. He sits mid-90s with a hard sinker that can climb as high as 100 mph. That power offering helped him post a superlative 57.6% ground-ball rate in the minors this year.
As things stand, this is the Angels’ lone 40-man addition of the day. Nothing is stopping them from making further moves to protect additional players, but the bulk of the top-ranked prospects in their thin farm system are either already on the 40-man roster or aren’t eligible to be selected in the Rule 5 Draft until 2026 or 2027. Righties Joel Hurtado and Samy Natera Jr. are notable exceptions, though both are coming off so-so seasons in the minors; Hurtado posted a bleak 15.5% strikeout rate as a 24-year-old in Double-A, while Natera walked 17% of his opponents out of the bullpen between Double-A and Triple-A.
