Royals Designate Joey Wiemer For Assignment

By | at

The Royals designated outfielder Joey Wiemer earlier today, and shifted left-hander Kris Bubic from the 15-day injured list to the 60-day IL.  The moves cleared some 40-man roster space after a busy day of transactions for Kansas City, as Mike Yastrzemski, Bailey Falter, Stephen Kolek, and Ryan Bergert were all brought into the organization.

Wiemer came to K.C. in another prominent trade last November, when Wiemer and Jonathan India came to the Royals from the Reds in exchange for Brady Singer.  Wiemer hasn’t received any big league playing time since the deal, and he has hit just .182/.291/.312 over 296 plate appearances at Triple-A Omaha.  This is Wiemer’s fourth straight season with at least a bit of action at the Triple-A level, and after some big numbers with the Brewers’ top affiliate in 2022, his production has steadily declined.

Almost all of Wiemer’s big league experience came in his 2023 rookie season, when he hit .204/.283/.362 over 410 plate appearances with Milwaukee.  He stole 11 bases in 15 attempts and displayed very good glovework at all three outfield spots, and those same skills combined with his hitting prowess early in his minor league career helped Wiemer get some top-100 prospect attention.  However, he made just 28 trips to the plate over 21 games with the Brewers and Reds in 2024, and the Royals are now the third team to seemingly lose faith in Wiemer’s ability to turn it around at the plate.  Some teams could take a flier on Wiemer as a late bloomer.

Even just as a glove-only bench piece, Wiemer has some value to other teams on the waiver wire, especially now that the deadline has passed and depth options are harder to acquire.  If Wiemer clears waivers, he can’t reject an outright assignment off the Royals’ 40-man roster, since he has neither a past outright on his resume or enough service time to be eligible for free agency.

Bubic will miss the rest of the season due to a rotator cuff strain, so it was just a matter of time before the Royals made it official by placing the southpaw on the 60-day IL.

A’s To Promote Luis Morales

By | at

The Athletics are calling up pitching prospect Luis Morales prior to tomorrow’s game with the Diamondbacks, according to reporter Francys Romero.  Morales will be making his Major League debut whenever he makes his first appearance in a game.  No corresponding moves will need to be made, as the Athletics’ deadline trades have left space on both the 26-man and 40-man rosters.

Mason Miller was one of the players dealt, as the A’s sent Miller and JP Sears to the Padres as part of a blockbuster six-player swap.  The 22-year-old Morales may slide right into Miller’s old bullpen role, if perhaps not specifically as a closer, given how Morales has been operating as a multi-inning reliever over his last month of Triple-A action.  While Morales had operated almost exclusively as a starter before the role change, the decision was made to help manage Morales’ innings.  He has already set a high career high with 89 1/3 frames in 2025, and the A’s are interested in seeing how Morales can now fare against big league hitters.

MLB Pipeline ranks Morales as the 80th-best prospect in baseball, and he also sat 79th in Baseball America’s preseason top-100 ranking.  The A’s gave the Cuban-born Morales a hefty $3MM bonus as an international prospect in 2023, and he has been living up to expectations by making a pretty quick rise through the farm system.  The 2025 season has seen Morales pitch at the Double-A and Triple-A levels for the first time, and he has a 3.73 ERA, 9.6% walk rate, and 29.2% strikeout rate over his 89 1/3 combined innings at the two affiliates in Midland and Las Vegas.

Morales’ control has been average at best, but he brings heavy velocity with a fastball that sits in the 96-97mph range, and cracking the 100mph threshold seems a possibility with this temporary move to the bullpen.  His slider is another quality pitch and his changeup has promise, but is a little more inconsistent.

Pipeline’s scouting report notes that Morales cut back to just these three pitches, and while he could reincorporate his curveball or another pitch down the road, narrowing an arsenal is usually a sign that an organization could be ultimately viewing a pitcher as a reliever over the long term.  The A’s will surely give Morales a chance to stick as a starter before considering a permanent move to the pen, of course, and he might well get a couple of starts in the majors in an early audition for 2026.

Astros Outright Jon Singleton

By | at

TODAY: Singleton cleared waivers and has been outrighted off Houston’s 40-man roster, the team announced.  It isn’t yet known if Singleton will accept the assignment or elect free agency.

JULY 28: The Astros are designating first baseman Jon Singleton for assignment, according to an announcement from Singleton’s wife Linzy on social media this afternoon. Additional roster maneuvering will be necessary to replace Singleton on the club’s active roster, but it’s not clear what the corresponding transaction will be at this point.

Singleton, 34 in September, was added to the club’s roster last week alongside Shay Whitcomb in the wake of an injury to third baseman Isaac Paredes last week. Singleton ultimately appeared in just three games for the Astros this year, during which he went 1-for-9 with at the plate with one strikeout and no walks. He began the season in the Mets’ minor league system but signed a minor league deal with Houston back in July. Between those two club’s Triple-A affiliates, Singleton has slashed a solid .224/.373/.451 this year with 16 homers in 306 trips to the plate.

The veteran first baseman previously was rostered by the Astros last year as their regular first baseman after the departure of Jose Abreu. Singleton provided a league average bat for the Astros at the position as he slashed .234/.321/.386 with a wRC+ of 104 across 119 games. It was a solid enough performance to earn Singleton consideration for the club’s 2025 roster, but Houston eventually pivoted away from Singleton due to incoming first baseman Christian Walker. With Walker at first base and Yordan Alvarez expected to serve as the club’s everyday DH, there was no path to playing time for Singleton in Houston. Injuries have opened up playing time since then, but the Astros have generally preferred to opt for younger or more versatile options like Taylor Trammell and Cooper Hummel when filling out their roster this year.

Singleton has plenty of history with the Astros organization. A top prospect in the Phillies’s system who was dealt to Houston in a trade for Hunter Pence, Singleton signed a five-year, $10MM extension with the Astros before he even made his MLB debut. The deal was widely viewed as a coup for the Astros at the time, but Singleton struggled upon arriving in the big leagues back in 2014 and slashed just .171/.290/.331 across two seasons in the majors. He did not resurface in the big leagues until the 2023 season and spent time playing both in the minors and for independent leagues during his years away from the majors.

The loss of Singleton leaves them without another lefty bat on the roster. Pending the corresponding move for Singleton’s exit, the Astros only have Trammell (as well as switch-hitters Hummel and backup catcher Victor Caratini) capable of batting from the left side on their roster. As for Singleton, the Astros will have until the trade deadline on July 21 to attempt to work out a trade involving him or else he’ll be passed through waivers. If he clears waivers unclaimed, he’ll have the opportunity to accept an outright assignment from the Astros and remain in their minor league system or test free agency.

Padres Designate Martin Maldonado, Trenton Brooks

By | at

The Padres have designated catcher Martín Maldonado and infielder Trenton Brooks for assignment, per an announcement from the team. San Diego also optioned newly acquired infielder Will Wagner to Triple-A El Paso. Among the numerous trades the Padres pulled off before the deadline were a deal for catcher Freddy Fermin (link) and one for first baseman/DH Ryan O’Hearn and outfielder Ramón Laureano (link). That influx of position player talent to the roster meant cuts were unavoidable, and Maldonado and Brooks were (two of) the odd men out.

Maldonado’s reputation as a strong game-caller has kept him employed long after most statistics suggested he should hang up his gear. From 2012-20, he caught more than 700 games and produced 13.2 FanGraphs WAR, the 14th most among primary catchers. While his bat was a liability, his glove was valuable enough to compensate. According to FanGraphs, only five players racked up more defensive value than Maldonado in that span: Yasmani Grandal, Buster Posey, Yadier Molina, Andrelton Simmons, and Russell Martin. Yet, Maldonado’s offense has only gotten worse, and his defense has dropped off too – at least according to stats like Defensive Runs Saved (DRS), Fielding Run Value (FRV), and Deserved Runs Prevented (DRP). Over the past five seasons, no player who has taken as many or more plate appearances has a lower OPS or wRC+, and without Gold Glove-caliber defense to make up for his feeble bat, he ranks among the league’s 10 worst players in fWAR since 2021. With the Padres seeking every possible edge as they look to hold onto their postseason position, it’s no surprise they wanted to improve behind the dish. Fermin isn’t a star, but he’s an upgrade in almost every quantifiable way.

Maldonado will most likely clear waivers, reject an outright assignment, and return to the open market as a free agent. On the one hand, it might seem unlikely that he’ll find another major league job, especially with his 39th birthday fast approaching. On the other hand, one could have said the same thing before he signed with the White Sox in 2024 and the Padres this season. Perhaps it would be foolish to count out Maldonado just yet.

Brooks spent time in the minors with the Guardians and Athletics organizations from 2016-23 before he finally made his MLB debut with the Giants in May of 2024. The lefty batter went 3-for-25 over 12 games, playing first base and DH, before he was DFA’d in June. He spent the rest of the season with San Francisco’s Triple-A affiliate, where he hit well; he finished the minor league season with a .302 batting average and a 132 wRC+ in 94 games. Brooks then inked a minor league pact with the Padres and continued mashing Triple-A pitching in the early part of 2025. He batted .311 with a 133 wRC+ in 60 games before he had his contract selected in mid-June. Unfortunately, he did not have anywhere close to the same kind of success at the MLB level, as he hit .146 with a 26 wRC+ in 25 contests. If Maldonado’s DFA was unsurprising, Brooks’s may well have been inevitable.

Now 30 years old, and with a .136/.208/.212 career slash line to show for his two brief stints in the majors, Brooks is hardly a prospect. Still, his impressive numbers at Triple-A over the past two years (.306/.410/.508, 24 HR, 38 2B, 104 BB, 104 K) might convince a team in need of some left-handed depth to claim him off waivers in the coming days.

Cubs Acquire Willi Castro

By | at

The Cubs have landed utilityman Willi Castro from the Twins, according to Jon Heyman of the New York Post.  Minnesota will receive multiple prospects in return, and ESPN.com’s Jesse Rogers specifies those players as minor league pitchers Ryan Gallagher and Sam Armstrong.

The switch-hitting Castro can play all over the diamond, but he’ll surely get most of his playing time in Chicago at third base.  The Cubs haven’t gotten much from the position all season, even though top prospect Matt Shaw has been on fire since the All-Star break.  Shaw could continue to get at-bats as long as he continues to hit, with Castro spelling him on occasion and moving into more of a regular role if Shaw comes back to earth.

Since coming to Minnesota as a free agent in the 2022-23 offseason, Castro has hit .250/.335/.398 over 1388 plate appearances and played at every position on the field except catcher and first base.  Beyond just being a plug-and-play fill-in for the Twins’ many injuries over the years, Castro forced his way into more of a regular role with his solid hitting from both sides of the plate, and a 34-steal season in 2023.  That havoc on the basepaths may have been a one-year outlier (he is 23-of-35 in steal attempts over the last two seasons), but Castro is nevertheless a solid all-around contributor.

Castro is also inexpensive, as the Cubs will owe him roughly $2MM for the remainder of the 2025 season before the utilityman enters free agency this winter.  Between his salary, rental status, and ability to fit into pretty much any roster, Castro drew a lot of buzz as the deadline approached, with such teams as the Astros, Yankees, and Mariners listed as known suitors.

This interest allowed the Twins to land two pitching prospects for a rental player.  MLB Pipeline ranks Gallagher as the eighth-best prospect in the Chicago farm system, while Armstrong just barely cracked Baseball America’s preseason Cubs ranking in the 30th spot on the list.  This duo will join the haul of young talent Minnesota received as part of their enormous deadline-day selloff.

Gallagher was a sixth-round pick in the 2024 draft, and he has already reached Double-A Knoxville in his first pro season.  Gallagher has a 3.43 ERA, 28.2% strikeout rate, and 5.9% walk rate over 84 combined innings at the high-A and Double-A levels, with 11 1/3 of those frames coming in Knoxville.  His top two pitches are a changeup and a fastball, with the latter pitch standing out for its “quality induced vertical break and command” (according to Pipeline’s scouting report) moreso than velocity in the 90-93 mph range.

Armstrong was a 13th-round pick for Chicago in 2023, and he has a 4.62 ERA, 19.3% strikeout rate, and 8.3% walk rate in 89 2/3 innings in Knoxville this season.  BA’s scouting report says Armstrong has “a kitchen sink’s worth of pitches” but perhaps not a true signature pitch among his six offerings, as his slider gets the highest grade with a relatively modest 50.  Armstrong has posted some good grounder rates across his minor league career, but it would seem he might have trouble continually fooling batters without premium stuff.

Brewers Designate Bryan Hudson, Elvis Peguero For Assignment

By | at

The Brewers designated relievers Bryan Hudson and Elvis Peguero for assignment. They also outrighted catcher Eric Haase, who was designated for assignment earlier in the week following the Danny Jansen trade, off the 40-man roster. He’ll have the option to elect free agency but will presumably accept his assignment, as Haase does not have enough service time to reject an assignment and retain the rest of his $1.35MM guaranteed salary.

Hudson, 28, was one of Milwaukee’s top relievers a year ago but has struggled through a down season in the majors and in Triple-A. He’s pitched 10 1/3 big league innings but logged a 4.35 ERA while walking 22.2% of his opponents. He’s limped to a 6.84 ERA in 25 Triple-A frames. Hudson’s velocity is down more than a mile per hour in 2025, and he’s sitting 90.1 mph with his fastball. His 18.3% opponents’ chase rate on balls off the plate is well south of average, and he’s allowing too much contact on balls both within the zone and off the plate.

It’s a far cry from one year ago. Hudson was a revelation after coming over in a DFA trade with the Dodgers. He tossed 62 1/3 innings with a 1.73 ERA, 26.8% strikeout rate and 7.4% walk rate. He obviously hasn’t been able to sustain that, but the recent track record might pique the interest of another club. This is Hudson’s final option year. He’d have to stick on the big league roster in 2026 or else be designated for assignment.

Peguero, 28, has spent two-plus seasons in Milwaukee. He was a regular in the bullpen from 2023-24, pitching a combined 112 2/3 innings with a 3.20 ERA. That solid run prevention came in spite of a sub-par 21.1% strikeout rate and bloated 11.1% walk rate, however. That poor command has caught up with Peguero in 2025, particularly since his velocity has also dropped.

In 2024, Peguero sat just under 97 mph with his fastball. He’s averaged a flat 95 mph in 2025 (95.4 mph in Triple-A). Peguero has only tossed 7 1/3 MLB frames this year, during which he’s been tagged for six runs (four earned) on eight hits and four walks, as well as one hit batter. He’s fanned five. Peguero’s 3.55 ERA in 25 1/3 Triple-A innings is solid, but he’s walked nearly 13% of his opponents in Nashville, plunked two more and thrown four wild pitches. He’s also in his final option season.

Both Hudson and Peguero will be placed on waivers within the next five days. With the deadline passed, there’s no opportunity to trade them. Both players will be made available to the game’s other 29 teams, with priority determined in reverse order of the MLB-wide standings.

Tigers Acquire Charlie Morton

By and | at

The Tigers have acquired right-hander Charlie Morton from the Orioles in exchange for minor league left-hander Micah Ashman. Baltimore will also send cash considerations. To free up space on their 40-man roster, the Tigers designated left-hander PJ Poulin for assignment. Jeff Passan of ESPN was the first to report that Morton was heading to Detroit.

Morton, 41, joins Chris Paddack as the Tigers’ second veteran rotation addition near the trade deadline.  Morton signed a $15MM free agent deal with the Orioles in January, but lost his rotation job after five disastrous starts.  After the Orioles designated Kyle Gibson for assignment on May 18th, Morton returned to the rotation.  He’s been a new pitcher in those 11 starts, posting a 3.88 ERA, 22.7 K%, and 8.9 BB%.

Now Morton joins the first-place Tigers, who are tied for the best record in the American League.  The club’s rotation consists of ace Tarik Skubal, Jack Flaherty, Casey Mize, Paddack, and Morton.  Reese Olson is out for the season with a shoulder strain, while free agent signing Alex Cobb was able to resume his rehab assignment on Tuesday as he recovers from a hip injury.  Rookie Troy Melton, who drew two starts this month, has been moved to the bullpen to accommodate Morton.

It’s unclear how the Tigers would make it work if all six veteran pitchers are healthy, but that’s a good problem to have.  Morton could perhaps serve as the Tigers’ fourth starter in the playoffs.  He has extensive postseason experience, including for manager A.J. Hinch’s 2017-18 Astros.

Perhaps because of the success of his team or a desire to hang on to his best prospects, Tigers president of baseball operations Scott Harris didn’t shoot for the top of the market at the trade deadline.  Aside from adding Morton and Paddack to the rotation, Harris picked up Kyle Finnegan, Rafael Montero, the injured Paul Sewald, and Codi Heuer as bullpen reinforcements.  It was not unlike the club’s offseason, which consisted of modest free agent deals for Flaherty, Cobb, Gleyber Torres, Tommy Kahnle, John Brebbia, Manuel Margot, and Jose Urquidy.

At one point it seemed like the Orioles might move three starting pitchers, but Zach Eflin and Tomoyuki Sugano ended up staying put.  Eflin was placed on the IL today with back discomfort, while Sugano likely didn’t move the needle for teams given his 15.2 K%.  The Orioles still traded Ryan O’Hearn, Ramon Laureano, Ramon Urias, Cedric Mullins, Andrew Kittredge, Seranthony Dominguez, Gregory Soto, and Bryan Baker this month, so it was an incredibly active trade deadline for Mike Elias and company.

Ashman, 22, was drafted in the 11th round by the Tigers last year out of the University of Utah.  The reliever has a 1.49 ERA and 25.5 K-BB% in the minors this year and moved to Double-A earlier this month.  It appears the Tigers are taking on all $4.76MM owed to Morton for the rest of the year, which likely dampened Baltimore’s return.

Tigers Trade Dietrich Enns To Orioles

By | at

The Orioles and Tigers apparently made a last minute trade before the deadline. Detroit dealt left-hander Dietrich Enns to Baltimore for cash. He’d been designated for assignment just this afternoon when the Tigers acquired Codi Heuer from Texas.

Enns, 34, could get a look in the Baltimore rotation. The O’s traded Charlie Morton and placed Zach Eflin on the injured list. They’re more or less playing out the string and need pitchers who can take innings behind Trevor Rogers and Tomoyuki Sugano. Enns has struggled in a limited big league look, giving up 12 runs in 17 2/3 frames spanning seven appearances. He has posted excellent numbers over 14 Triple-A starts, working to a 2.89 ERA with a near-27% strikeout rate against a tidy 5.6% walk percentage.

Prior to this season, Enns’ major league experience consisted of brief stints with the 2017 Twins and ’21 Rays. He has also pitched in Japan and Korea, turning in a 4.19 ERA over 30 starts in the KBO last season. The O’s will give him an opportunity to see if they can get similar mid-30s production from Enns as they did with Albert Suarez a year ago.

Yankees Acquire Camilo Doval

By and | at

The Yankees are acquiring right-handed reliever Camilo Doval from the Giants, reports Jack Curry of YES Network. In exchange, the Giants will receive four minor leaguers: Jesus Rodriguez, Trystan Vrieling, Parks Harber, and Carlos De La Rosa. Curry was the first to report that Rodriguez, Vrieling, and Harbor were included in the deal, while FanSided’s Robert Murray later reported the complete package.  The deal is now official.

In adding Doval, David Bednar, and Jake Bird today, Yankees GM Brian Cashman was able to acquire three relievers with control beyond this season.  That should be useful given the impending free agencies of Devin Williams and Luke Weaver.

Doval, 28, has a 3.09 ERA, 26.2 K%, 12.6 BB%, and 52.6% groundball rate in 46 2/3 innings for the Giants this year.  Doval burst onto the scene in 2021 as one of baseball’s hardest-throwing relievers.

Unlike most baseball executives, Giants president of baseball operations Buster Posey had firsthand experience with Doval’s talent, having served as his catcher in Posey’s final season.  As a rookie, Doval made three appearances in the NLDS for the Giants.

A few months in the 2022 season, Doval was entrenched as the Giants’ closer.  He had a couple of strong years, including 39 saves and an All-Star appearance in 2023.  However, with his walk rate spiking to 14.4% in 2024, Doval was sent to Triple-A in August as Ryan Walker took over closing duties.  By the end of May this year, Doval had won his closer job back.

Doval has had better results this year with a 3.09 ERA, though his still lives in dangerous territory with a 12.6% walk rate.  Some of that is mitigated by his ability to keep the ball on the ground.  Doval likely won’t be tasked with the ninth inning for the Yankees, given the presence of Williams, Bednar, and Weaver.

Doval is under team control through 2027.  He’s earning $4.525MM in his first arbitration year, about $1.44MM of which remains this season.  Given the Yankees’ 110% competitive balance tax bracket, they’ll spend about $3MM to have Doval for the remainder of this season.  The club has run its CBT payroll up to about $316MM, according to RosterResource.

Posey’s Giants, meanwhile, save money and further stock the cupboard with minor leaguers, having also traded Mike Yastrzemski and Tyler Rogers in the last few days.  According to Baseball America, De La Rosa has the best upside of the four acquired for Doval.  The 20-year-old righty was graded 45/extreme risk by BA, who called him a “fine lottery ticket” who is on the upswing.  BA graded Rodriguez as 40/high risk, suggesting he “could have a future as a second-division regular who takes reps behind the plate and occasionally at third base.”

Though unranked by BA, Vrieling is more highly regarded by MLB.com, who assigned the righty a 40 grade.  They concluded, “he’ll have no more than a back-of-the-rotation ceiling unless he can develop a better-than-average offering.”  Harber, now 23, was signed as a non-drafted free agent by the Yankees.  He’s reached High-A this year as a corner infielder.  He may be a bit old for his level, but Harber has a 156 wRC+ in 152 PA and may soon prove ready for Double-A.

Royals Acquire Mike Yastrzemski

By and | at

The Royals have acquired outfielder Mike Yastrzemski from the Giants in a last-minute deadline swap. In exchange, the Giants will receive right-handed pitching prospect Yunior Marte. Mark Feinsand of MLB.com was the first to report that Yastrzemski was headed to Kansas City.  The deal is now official.

Yastrzemski, 34, has slipped to a 97 wRC+ in 372 plate appearances for the Giants this year in his seventh season with the club.  From 2023-24, he’d managed a 109 mark.  A left-handed hitter, Yaz has always excelled against right-handed pitching, including a 118 wRC+ this year.

Yastrzemski, who has primarily played right field in the Majors, joins a 54-55 Royals team that nonetheless sits three games back in the Wild Card race.  He’s a perfect pairing with the newly-acquired Randal Grichuk, a right-handed hitter.  Rookie Jac Caglianone, who had spent time in right field, is on the IL with a hamstring strain.  Yastrzemski, famously the grandson of Hall of Famer Carl, will be eligible for free agency after the season.

As Justice delos Santos of the San Jose Mercury News notes, “With Yastrzemski gone, the door is open for Luis Matos to step into a starting role [for the Giants]. It’s very possible Grant McCray and Marco Luciano see some time in right field as well.”

In parting with their longtime right fielder for the next few months, the Giants add Marte.  The 21-year-old has spent the season in A ball, posting a 2.74 ERA and 18.4 K-BB% in 19 starts.  Baseball America assigned him a 50 high risk grade, noting that he “features two above-average pitches in his arsenal.”
