Orioles Designate Emmanuel Rivera For Assignment
The Orioles have designated infielder Emmanuel Rivera for assignment and reinstated Jordan Westburg from the 10-day injured list, per a team announcement. Baltimore also optioned lefty Grant Wolfram to Triple-A Norfolk, clearing a spot for the activation of lefty Jose Castillo, whom the O’s claimed off waivers yesterday.
Rivera, 29, came to the Orioles following a DFA in Miami last summer. He erupted for a .313/.370/.578 slash and four homers in 73 plate appearances down the stretch, prompting the O’s to tender him a $1MM contract in the offseason. He hasn’t replicated that output in 2025, however. Through 127 turns at the plate, Rivera has logged a tepid .250/.291/.283 slash that more closely resembles his career .245/.305/.360 output in 1169 plate appearances.
He’s still a quality defender at third base and has added some experience at first base, but Rivera is out of minor league options and thus couldn’t simply be sent to the minors without first being removed from the 40-man roster by way of a DFA. He’ll now be made available to the game’s 29 other teams via outright waivers. If and when he clears, Rivera would have the right to reject a minor league assignment in favor of free agency (both by virtue of having more than three years of MLB service and a prior outright in his career).
It’s been a stop-and-start year for the 26-year-old Westburg. He’s been highly productive when healthy enough to take the field but has endured lengthy IL stints owing to both a hamstring strain and a right ankle sprain. He’s just now returning from the latter of those two maladies after spending nearly a month on the shelf.
When he’s been able to take the field, Westburg has popped 25 extra-base hits (15 homers, nine doubles, one triple) and recorded a stout .276/.326/.473 batting line while splitting his time between third base and second base. Dating back to last season, Westburg has belted 33 home runs in just 751 plate appearances — despite being a right-handed hitter in a ballpark that overwhelmingly sapped right-handed power in 2024 (before altering their left field dimensions this past offseason).
Westburg is controllable for another four seasons in Baltimore and won’t be eligible for arbitration until after the 2026 season. He’s been limited to just 73 games this season, but he’s demonstrated potential 30-homer pop if he can remain healthy for a full year. He’ll enter the offseason lined up as the Orioles’ starter at third base, joining shortstop Gunnar Henderson and second baseman Jackson Holliday as locks in the infield at Camden Yards.
Former top prospect Coby Mayo is currently getting plenty of run at first base but has yet to solidify himself as a credible hitter at the MLB level. Samuel Basallo, another touted prospect (whom the Orioles recently extended), will also be in the mix for reps at first base. Longtime O’s slugger Ryan Mountcastle is also still in the picture, but he’s slumping badly to close out a down year overall and will be owed a raise on this year’s $6.78MM salary ahead of his final season of club control, making him a non-tender or trade candidate.
Pirates Select Rafael Flores
The Pirates announced that they have selected the contract of catcher/first baseman Rafael Flores. In a corresponding active roster move, infielder Liover Peguero has been optioned to Triple-A Indianapolis. The 40-man roster had a vacancy but is now full.
Flores, 24, was just acquired from the Yankees as part of the deadline deal sending David Bednar to the Bronx. He was going to be available in the upcoming Rule 5 draft if not added to Pittsburgh’s 40-man roster. They were surely planning to give him a roster spot in order to him from that draft. Doing so a few months early allows them to get a look at him in the big leagues before the offseason arrives.
The youngster took an unusual path to being a notable prospect. He attended Rio Honda, a community college outside Los Angeles, and was playing summer ball for the Alaska Goldpanners when the Yanks found him and signed him as an undrafted free agent in 2022. He was roughly league average at the plate in 2023 while playing at the High-A level.
Flores seemed to take a big step forward last year, both offensively and defensively. He stepped to the plate 506 times between High-A and Double-A, producing a combined .279/.379/.495 line and 152 wRC+. FanGraphs ranked him 34th in the system prior to that campaign, noting that his work behind the plate was improving. Baseball America ranked him tenth among New York farmhands heading into the current season.
The 2025 season has seen Flores boost his stock even further. The righty-swinging 24-year-old clobbered Double-A pitching at a .287/.346/.496 pace (145 wRC+) in 370 plate appearances and has hit .281/.363/.459 (119 wRC+) in 157 Triple-A plate appearances with the Pirates following the trade. He’s not great when it comes to controlling the running game, but Baseball Prospectus gives him above-average framing and blocking grades in the minors this year. At the very least, he has the makings of a bat-first option behind the plate — an area of dire need for the Pirates for the past several years.
Catcher has been a revolving door in Pittsburgh ever since the Bucs traded Jacob Stallings to the Marlins after the 2021 season. They’ve since used a combination of Henry Davis, Endy Rodriguez, Joey Bart, Jason Delay, Yasmani Grandal, Tyler Heineman, Austin Hedges, Michael Perez, Andrew Knapp and Roberto Perez — among others — and received disastrous results with the bat. Only the Guardians have received less offensive output from their catchers than Pittsburgh’s combined .208/.285/.314 since Opening Day 2022.
The hope moving forward will be that Flores can turn that tide — or at least play a meaningful role in a catching committee that begins to right the ship. The Pirates’ offense, in general, is among the most anemic in baseball on an annual basis. If Flores can provide even average offense (or slightly above), he ought to receive plenty of looks moving forward, given the difficulty the Bucs have had when it comes to scoring runs year over year.
Braves Select Jose Suarez
The Braves announced Tuesday that they’ve selected the contract of lefty José Suarez from Triple-A Gwinnett. Catcher Sean Murphy, who underwent season-ending hip surgery recently, was moved to the 60-day IL to open a spot on the 40-man roster. Atlanta also recalled righty Nathan Wiles from Gwinnett and optioned righties Connor Seabold and Alexis Díaz to Triple-A in a series of corresponding moves.
Suarez will make a spot start in Game 1 of today’s doubleheader in Washington. He’ll be opposed by Nationals righty Jake Irvin, who has struggled to a 5.70 ERA over 30 starts. There’s a much more exciting pitching matchup with Chris Sale and MacKenzie Gore squaring off in the nightcap.
Atlanta acquired Suarez from the Angels in a swap for Ian Anderson at the end of Spring Training. The 27-year-old southpaw began the season in Brian Snitker’s bullpen. He tossed 7 1/3 innings over three appearances, allowing three runs (two earned) with seven walks and five strikeouts. Atlanta designated him for assignment and ran him through outright waivers at the end of April.
Suarez has spent most of the season on the minor league injured list. He has been limited to nine appearances (eight starts) with Gwinnett, where he has pitched to a 3.53 ERA over 43 1/3 frames. Suarez has punched out 28% of opponents with a sub-5% walk rate. That earns him at least his first MLB start of the season, and it’s possible he’ll stick on the big league roster in long relief for the last two weeks. Suarez will be controllable through arbitration if he finishes the season on the 40-man roster, though he’d likely be non-tendered.
Matt Strahm Triggers Vesting Option
Phillies reliever Matt Strahm completed a perfect eighth inning for a hold tonight against the Dodgers. In the process, he crossed the 60-inning threshold and vested a $7.5MM option for the 2026 season. The southpaw will still need to pass a postseason physical for the option to go into effect.
Strahm initially joined the Phils on a two-year, $15MM free agent contract during the 2022-23 offseason. That has turned into an excellent value for Dave Dombrowski’s front office. Strahm turned in a 3.29 ERA across 87 2/3 innings during his first season with the club. Philadelphia signed him to a one-year extension for the 2025 season before the ’24 campaign even got underway.
The 33-year-old Strahm has responded with arguably the best two years of his career. He worked to a 1.87 ERA over 66 appearances a year ago and holds a 2.83 mark in 60 1/3 frames this season. His velocity has ticked down, but he’s still punching out 28% of batters faced against an 8% walk rate. He carried a solid 11.7% swinging strike percentage into tonight’s performance.
Philly has increasingly leaned on Strahm as one of their top bullpen weapons. He has a career-best 21 holds. In the second half, only closer Jhoan Duran has entered in higher-leverage situations on average. Strahm is alongside David Robertson and Orion Kerkering as the Phils’ top setup arms going into the playoffs. José Alvarado is ineligible for the postseason because of his failed performance-enhancing drug test. Strahm and Tanner Banks will go into October as manager Rob Thomson’s top two southpaws, while waiver pickup Tim Mayza looks like a borderline candidate to make the playoff roster.
The Phillies would very likely have exercised Strahm’s option even if he had fallen shy of the 60-inning mark. Philadelphia will be happy to retain him on an affordable salary for a leverage reliever. Duran will be back in the ninth inning, while Kerkering and Banks remain under control for multiple seasons. The Phils hold a $9MM option on Alvarado, whose season ended last week when he was diagnosed with a forearm strain.
Giants Designate Brett Wisely For Assignment
The Giants officially announced the previously reported promotion of top first base prospect Bryce Eldridge. San Francisco optioned outfielder Luis Matos to clear a spot on the big league roster. They designated utility infielder Brett Wisely for assignment to open the necessary 40-man roster spot.
Eldridge, who is still a month away from his 21st birthday, steps right into the fire in a pennant race. He’s batting fifth and serving as the designated hitter against Zac Gallen (relayed by Justice delos Santos of The Mercury News). The Giants are keeping Rafael Devers at first base tonight. San Francisco is half a game ahead of the Diamondbacks and trails the Mets by a game and a half for the National League’s last Wild Card spot.
Wisely has been on San Francisco’s 40-man roster for the past three seasons. Farhan Zaidi was running baseball operations when the Giants acquired him from the Rays early in the 2022-23 offseason. Wisely would have qualified for the Rule 5 draft, but San Francisco selected his contract to ensure they retained his rights. The former 15th-round pick has been up and down between Oracle Park and Triple-A for the last three seasons.
The lefty-hitting Wisely hasn’t produced much against big league pitching. He owns a .217/.263/.324 line with seven home runs across 457 plate appearances. He hit very well in Triple-A between 2023-24, but his minor league numbers this year have also been underwhelming. Wisely carries a .253/.332/.387 line with seven longballs and 12 steals in 80 games at Triple-A Sacramento this season. He has only appeared in 22 MLB contests as a result, hitting .208 with one homer in 54 trips to the plate.
While this hasn’t been a good season, Wisely has some positive attributes that could get interest on the waiver wire. He grades as a solid defender at second base and has experience at every position aside from catcher. He’s never going to hit for much power, but he has shown solid on-base skills in the minors. He owns a .274/.371/.433 line in nearly 200 career Triple-A games across four seasons.
San Francisco will place Wisely on outright waivers within the next few days. He’s in his last minor league option year. Another team may put in a claim and stash him in Triple-A for the rest of the season. He’ll be out of options next year. If he sticks on a 40-man roster into Spring Training, he’d need to break camp and remain in the majors or again be designated for assignment.
Phillies Outright Matt Manning
The Phillies announced that Matt Manning has been outrighted to Double-A Reading. He cleared waivers after being designated for assignment on Saturday as the corresponding move for Walker Buehler’s promotion.
It’s the first career outright assignment for Manning, the ninth overall pick in 2016. The Tigers draftee was part of a touted contingent of pitching prospects that also included Tarik Skubal and Casey Mize. Manning hasn’t had anywhere near the same level of success as Mize, much less approached Skubal’s ace form. The lanky right-hander started 50 games for Detroit between 2021-24. He pitched to a 4.43 earned run average with a well below-average 16.4% strikeout rate across 254 innings.
Manning has not spent any time in the majors this season. Detroit optioned him fairly early in Spring Training. They’d used him mostly out of the bullpen in Triple-A, but that didn’t spur much success. He was carrying a 6.04 ERA over 31 appearances when the Tigers designated him for assignment at the trade deadline. They flipped him to Philly for a low minors outfielder (Josueth Quinonez). The Phils sent Manning back to Double-A, where he walked seven batters and allowed six runs in five innings over a pair of starts.
The 27-year-old Manning will finish the season in the Phils organization. He’ll become a minor league free agent at the end of the season unless Philadelphia adds him back to the 40-man roster within the next few weeks. He should be able to find a minor league contract somewhere over the winter.
Diamondbacks Designate Anthony DeSclafani For Assignment
The Diamondbacks announced that veteran righty Anthony DeSclafani has been designated for assignment. His spot in the bullpen goes to hard-throwing righty Juan Morillo, who has been recalled from Triple-A Reno. Arizona’s 40-man roster count drops to 39.
DeSclafani was pitching in Triple-A with the Yankees when Arizona signed him to a big league contract in the middle of June. He initially worked out of long relief and was promoted to the rotation when the Snakes traded Merrill Kelly at the deadline. That lasted only three starts, as DeSclafani suffered a thumb injury in the middle of August and was sent to the injured list. He missed a month and has been pushed back to the bullpen since returning. Nabil Crismatt has stepped into the fifth starter job.
The 35-year-old DeSclafani has pitched twice since coming back from injury. He has given up five home runs (six runs overall) in 5 2/3 frames over those two outings. He carries a 5.12 ERA across 38 2/3 innings on the season overall. While his strikeout and walk numbers are serviceable, the recent home run barrage led the Snakes to make a change. DeSclafani will very likely be released this week.
Morillo also represents a fresher arm for Torey Lovullo’s bullpen. He hasn’t pitched since Thursday. DeSclafani tossed 2 2/3 frames and threw 59 pitches yesterday. He would not have been available for at least the first two games of what is probably a must-win series if Arizona is to snag a surprise playoff berth. The D-Backs host the Giants for a three-game set. They’re half a game behind San Francisco and two games back of the reeling Mets for the National League’s last Wild Card spot.
Blue Jays Designate Ryan Borucki For Assignment
4:43pm: Manager John Schneider says Borucki informed the Jays he hopes to stay in the organization for the rest of the season (relayed by Arden Zwelling of Sportsnet). There’s a good chance he clears waivers as an impending free agent, and it seems he intends to accept an outright assignment and report to Triple-A Buffalo if that proves to be the case.
3:33pm: The Blue Jays announced Monday that left-handed reliever Ryan Borucki has been designated for assignment. His spot on the roster will go to top prospect Trey Yesavage, whose previously reported promotion is now official.
Yesavage will make his major league debut tonight in Tampa Bay. He’ll start opposite hard-throwing Rays righty Joe Boyle. Yesavage, last year’s first-round pick out of East Carolina, made a quick ascent through the minors. He didn’t pitch at all in his draft year and began this season in Low-A. He pitched his way through each full season minor league level and now gets a couple weeks to make a case for inclusion on Toronto’s playoff rosters.
That decision probably ends Borucki’s second stint with the Blue Jays. Toronto signed him to a minor league contract late last month after he was released by the Pirates. The Jays selected his contract a little over a week later. Borucki managed 4 1/3 scoreless frames across four appearances, though he walked four of the 19 hitters he faced. The southpaw tossed 30 2/3 innings for the Bucs earlier in the season, working to a 5.28 earned run average. He had middling strikeout and walk numbers but got ground-balls at a 55% clip.
The Jays are familiar with Borucki, whom they drafted out of high school more than a decade ago. That came under a previous front office, but he spent his first four and a half MLB seasons with Toronto under the current regime. They evidently weren’t planning to carry him as a situational grounder specialist in the postseason. They’ll place him back on waivers within the next few days, and he could get a head start on the offseason by electing free agency if he goes unclaimed. Borucki would be a free agent this offseason either way, and he would not be playoff eligible if another team were to claim him.
Orioles Claim Jose Castillo, Designate Carson Ragsdale
The Orioles announced Monday that they’ve claimed left-handed reliever Jose Castillo off waivers from the Mariners. Righty Carson Ragsdale was designated for assignment in a corresponding move. Baltimore also placed righty Albert Suarez on the 15-day IL due to right elbow discomfort and recalled fellow righties Chayce McDermott and Yaramil Hiraldo from Triple-A Norfolk.
Castillo, 29, joins his fourth team of the 2025 season. He’s suited up for not only the Mariners but also the Mets and D-backs. The well-traveled southpaw has pitched 24 2/3 innings and turned in a 4.38 ERA with a 19.5% strikeout rate and 9.3% walk rate. He’s tallied three holds in five situations, but lefties (.390/.469/.561) and righties (.300/.377/.455) have both hit well against Castillo in limited appearances.
This marks Castillo’s first generally healthy season since his rookie year in 2018, when he pitched 38 1/3 innings of 3.29 ERA ball for the Padres. Injuries decimated the lefty’s career; he pitched only 1 2/3 big league innings combined from 2019-24 and didn’t top 37 2/3 innings at the minor league level in any season along the way. Castillo can still be controlled another two seasons beyond the current year, if he sticks on the Orioles’ 40-man roster.
Ragsdale, 27, is a longtime Giants farmhand who made his way to the O’s via waivers earlier this summer. He made his big league debut with Baltimore, tossing three innings but serving up eight runs on nine hits and a walk with two strikeouts. The 2020 fourth-rounder had solid numbers throughout much of his minor league tenure but has stumbled to a 4.87 earned run average with just a 19.7% strikeout rate and a 12% walk rate.
Ragsdale notched a 2.93 ERA in High-A and a 3.49 mark in Double-A, but he’s barely kept his ERA under 5.00 in parts of two Triple-A seasons. He’s sitting 92.6 mph on his four-seamer this year, complementing the pitch with a high-70s curveball and a splitter — the former of which has previously drawn plus grades in scouting reports. Ragsdale has two minor league option years remaining beyond the current season, which could heighten his appeal to clubs in need of pitching depth.
As for the 35-year-old Suarez, this elbow issue will end his season. He’s missed most of the 2025 campaign due to a separate shoulder injury. Suarez pitched well in 11 2/3 big league innings between injuries, logging a 2.31 ERA with a 10-to-2 K/BB ratio. The journeyman righty was a godsend for the O’s in 2024, going from a minor league signee to a key member of the staff who tossed 133 2/3 innings with a 3.70 ERA.
Suarez pitched in the majors with the Giants from 2016-17 and then spent the 2019-23 seasons starring in Japan’s Nippon Professional Baseball (2019-21) and the Korea Baseball Organization (2022-23). The O’s can control him for three more seasons via arbitration, but it’s not clear how severe his current elbow ailment is or how much time it might cause him to miss.
Seth Martinez Clears Waivers, Elects Free Agency
Right-hander Seth Martinez went unclaimed on waivers after being designated for assignment, per the transaction log at MLB.com. Miami assigned him outright to Triple-A Jacksonville, but Martinez has rejected that assignment in favor of free agency — as is his right as a player who’s previously been outrighted in his career.
The 31-year-old Martinez pitched just 6 2/3 innings with the Marlins in 2025, during which he allowed four runs on four hits and three walks with four punchouts. He’s now pitched in parts of five big league seasons, with all but this year’s Marlins cup of coffee coming in an Astros uniform. The Arizona State product has logged 144 innings in the majors and delivered a flat 4.00 ERA with a 20.5% strikeout rate, a 9.3% walk rate, a 38.6% ground-ball rate and 1.06 homers per nine innings pitched.
Martinez has never been a hard thrower, but this year’s 90.1 mph average four-seamer and 88.8 mph average sinker both represent career-low marks. Those obviously came in small samples, but Statcast shows that his velocity in the upper minors was virtually identical.
In 43 2/3 innings at the Triple-A level this season, Martinez worked to a solid 3.71 earned run average. He fanned 28.9% of his opponents despite that lackluster velocity, and his 9.6% walk rate mirrored what he’s posted in big major league career. In parts of five Triple-A seasons, Martinez touts a 2.97 ERA through 148 2/3 frames. We’re close enough to the end of the season that he may just remain a free agent until the offseason is underway. Regardless, he’ll likely land a minor league deal on the open market.
