Orioles Outright Houston Roth
The Orioles announced that right-hander Houston Roth has cleared outright waivers and been assigned to Triple-A Norfolk. He had been designated for assignment earlier this week when the O’s claimed Daniel Johnson and selected right-hander José Espada.
Roth, 27, was selected to Baltimore’s roster on July 29th. As part of their deadline selloff, the O’s had already sent out Gregory Soto and Seranthony Domínguez at that time. Andrew Kittredge was also traded a couple of days later.
That allowed Roth to stick on the big league roster for a few days but he was optioned back to the minors before getting into a game. A week after being optioned, he was bumped off the 40-man and no club grabbed him off waivers. This is his first outright and he has less than three years of service time, so he doesn’t have the right to reject the assignment.
In his minor league career, he has often been able to get strikeouts but has also given out walks at a notable pace. This year, he has thrown 39 innings between Double-A and Triple-A with 2.08 earned run average, 26.1% strikeout rate and 11.8% walk rate.

Astros Place Josh Hader On Injured List Due To Shoulder Strain
August 13: Espada provided a vague yet ominous update today. Hader is seeking a second opinion on his shoulder and will be on the IL beyond the minimal stint. “This is going to take a little bit longer than the two weeks,” he said, per Brian McTaggart of MLB.com.
August 12, 11:59 pm: Espada says he won’t name a new closer in Hader’s place, suggesting he will instead take a mix-and-match approach to filling the late innings (per Kawahara).
4:14 pm: Espada tells the Astros beat that Hader will receive additional testing (link via Matt Kawahara of the Houston Chronicle). The team has not yet ascertained the severity of the strain and thus do not have a firm timeline on his potential return.
3:15 pm: The Astros announced that closer Josh Hader has been placed on the 15-day injured list due to a left shoulder strain. An immediate timetable for his return was not revealed. Houston recalled lefty Colton Gordon from Triple-A in a corresponding roster move. The Astros also reinstated righty Shawn Dubin from the injured list and opened a roster spot by designating veteran reliever Hector Neris for assignment.
Remarkably, this is the first time Hader has ever been placed on the major league injured list (excepting a brief 2021 placement on the Covid-related IL). He’s not only been one of the sport’s most dominant relievers but also its most durable reliever. Dating back to Hader’s midseason debut in 2017, only Raisel Iglesias (who spent the entire ’17 season in the majors) has more innings pitched. (Somewhat ironically, Neris ranks third among all relievers in innings pitched during that time.) From 2018-25, only two innings separate Iglesias (466 2/3) and Hader (464 2/3) for the MLB lead.
After an up-and-down first year with Houston in 2024, Hader has been back to his typically dominant self in 2025. He’s totaled 52 2/3 innings and worked to a 2.05 earned run average while piling up 28 saves and punching out an outstanding 36.9% of his opponents against a quality 7.6% walk rate. Hader’s sinker is averaging 95.5 mph, down about a half-mile from last season, and he’s throwing his slider more than ever before — at a 41.4% clip. His colossal 21.1% swinging-strike rate is tied with Mason Miller for tops among all big league pitchers — starters and relievers alike — with at least 10 innings pitched this season.
Hader is in the second season of a five-year, $95MM contract he signed as a free agent in the 2023-24 offseason. It’s the second-largest contract ever for a reliever, both in terms of total guarantee and average annual value, trailing only Edwin Diaz (in both regards). That contract pays him an evenly distributed $19MM annually from 2024-28.
As for the 36-year-old Neris, he’s pitched for the Astros, Angels and Braves this year but struggled with all three. The right-hander has pitched a combined 26 2/3 innings with just a 6.75 ERA to show for it. Much of the damage against him came early in the season with Atlanta, but Neris posted a 5.14 with the Angels and is at 5.40 in 11 2/3 frames during what’s been his third stint as a member of the Houston bullpen.
While Neris has never exactly been a flamethrower, this year’s 92.4 mph average four-seamer is a career-low, falling shy of last year’s career-low 93 mph average. The 92.6 mph he’s averaging on his sinker is also a career-low. Neris is generating fewer whiffs, chases and grounders than ever before on his go-to splitter as well.
Since the trade deadline has passed, the Astros’ only course of action with Neris will be to place him on outright waivers or release waivers. They’re effectively the same thing for a player in Neris’ situation at this point, as he has the right to reject an outright assignment in favor of free agency anyhow and is quite likely to do so. If another club can get the veteran righty back on track, he’d be postseason-eligible with that new team so long as he was signed prior to Sept. 1.
With Hader on the shelf and Neris off the roster, the Houston bullpen will now look to righty Bryan Abreu as its anchor. He’s the immediate favorite to pick up saves in Hader’s place. Lefties Bryan King, Bennett Sousa and Steven Okert all have a 3.10 ERA or better on the season and figure to collect the majority of setup opportunities while Hader is out.
Since the Astros don’t have another shutdown righty beyond Abreu, it’s at least possible that Abreu could see work in the eighth inning if the Astros’ opponent has a run of tough righties, which would thus leave the ninth inning for one of that trio of lefties. That said, both King and Okert have been terrific against both righties and lefties. That gives manager Joe Espada plenty of options late in the game, but the loss of Hader is nonetheless a crucial blow as Houston tries to fend off a surging Mariners club that has rattled off seven straight wins to pull within one game of the AL West lead.
Diamondbacks Release Jeff Brigham
The Diamondbacks have released right-hander Jeff Brigham, according to his transactions tracker at MLB.com. He had been designated for assignment by the Diamondbacks on Monday, so this doesn’t impact the club’s 40-man roster count.
Brigham, 33, signed a minor league deal with the Snakes in the offseason. He was selected to the big league roster at the end of May but only made four appearances for the big league club before being optioned back down to Triple-A Reno. After rejoining the Aces, he bounced on and off the minor league injured list. He was on the shelf from June 17th to July 25th, then landed back on the IL July 29th.
At the time of his DFA this week, he was still on the IL. Injured players can’t be placed on outright waivers. Since the trade deadline has passed, that left release waivers as the only option for the Diamondbacks.
It’s unclear what Brigham’s current health status is. He now has a 4.85 earned run average in 120 2/3 career big league innings. He has struck out 23.8% of batters faced while giving out walks to 10.7% of opponents.

Nationals To Activate Dylan Crews Tomorrow
The Nationals are planning to reinstate outfielder Dylan Crews from the 60-day injured list tomorrow, reports Grant Paulsen of 106.7 The Fan. He’ll serve as the designated hitter today in what will be his final Triple-A rehab game before rejoining the big league club. Washington has multiple 40-man roster vacancies, so the Nats will only need to clear a spot on the active roster. Crews has been out since late May due to a significant oblique strain.
Crews, 23, was the No. 2 overall pick in the 2023 draft, going one pick after college teammate Paul Skenes. The LSU product debuted late last year and broke camp with the Nats in 2025, but he’s yet to produce at the levels expected for a former top pick who ranked as one of the sport’s best prospects prior to graduating to the majors. Crews has tallied 305 big league plate appearances and posted only a .206/.275/.354 slash in that time.
A disastrous start to his 2025 season has perhaps disproportionately skewed both his 2025 results and his career line to date. Crews was hitless through his first 19 plate appearances this year and struggled considerably for a couple weeks even after getting off the schneid. Through April 14, Crews took 49 turns at the plate and hit .106/.143/.106 with a 36.7% strikeout rate.
Things began trending up from there. Crews went on an eight-game hitting streak, followed that with a series of multi-hit performances and began turning his season around. He homered in his final two games prior to landing on the injured list. The overall production still wasn’t elite, but from April 15 through his May 21 IL placement, Crews hit .234/.315/.459 (116 wRC+) with seven home runs and a greatly reduced 24.2% strikeout rate in 124 plate appearances. Along the way, he averaged 90.9 mph off the bat and posted a strong 44.4% hard-hit rate.
It’s been a similar story on his minor league rehab stint. Crews was hitless in his first three Triple-A games but has shaken off the rust with a .294/.333/.500 slash over his past nine games with Rochester (36 plate appearances). He’ll get one final tune-up today before returning to the Nats tomorrow. That’ll give Crews a bit more than six weeks to hopefully build on the momentum he appeared to be gaining from mid-April through late May.
Even with the slow start to his big league career, Crews is still seen as a key piece of the Nationals’ future. He’s controllable for five more years beyond the current season and won’t even turn 24 until February. If he can continue his upward trajectory in the final few weeks of the season, there’ll be some optimism about the long-term outlook in the outfield. James Wood is an emerging star who’ll likely top 30 homers in his first full major league season. Crews can handle center but profiles better in right, leaving center field up for grabs among a group including defensive standout Jacob Young, former top picks Robert Hassell III and Daylen Lile, and deadline pickup Christian Franklin (who came over from the Cubs in the Michael Soroka trade).
Astros Select Jordan Weems
The Astros announced Wednesday that they’ve selected the contract of right-handed reliever Jordan Weems from Triple-A Sugar Land. Left-hander Colton Gordon was optioned to Triple-A in a corresponding move. Houston had an open 40-man spot.
It’s Weems’ second Astros stint of the season. He was up briefly from late June into early July, tossing three innings and allowing a pair of runs on five hits and no walks without a strikeout. Weems had opened the season in the Braves organization after signing a minor league deal but opted out of that contract and landed with Houston instead. He’s pitched well for their Triple-A club, logging 17 2/3 innings with a 3.06 ERA, 24.3% strikeout rate and 9.5% walk rate.
Weems, 32, has now pitched in parts of six major league seasons. He’s previously suited up for the A’s, D-backs and Nationals. Add in his brief stint with the ‘Stros earlier in the summer, and the 6’4″ righty has totaled 158 2/3 big league frames with a 5.28 ERA, 23.2% strikeout rate, 11.1% walk rate and 37% ground-ball rate. He’s not far removed from posting a 3.62 ERA in a career-high 54 2/3 innings with the 2023 Nats, though that production came in spite of an ugly 12.1% walk rate and 1.48 HR/9. Some regression seemed inevitable, and Weems indeed struggled mightily with the ’24 Nats.
The call to the majors for Weems comes just one day after Houston placed star closer Josh Hader on the injured list with a shoulder strain. It’s still not clear how long Hader will be sidelined. Obviously, Weems isn’t going to be viewed as any kind of replacement. The Astros will mix and match in the ninth inning, giving save opportunities to righty Bryan Abreu and lefties Bryan King, Bennett Sousa and Steven Okert. Weems adds some depth to backfill the bullpen, though it’s also possible that he’s just being called up as a fresh arm and is in for another short stint on the roster. Houston was shellacked 14-1 at the hands of the Red Sox yesterday and used three relievers before turning things over to outfielder Chas McCormick to pitch the final two frames of mop-up work.
White Sox Designate Jared Shuster For Assignment
The White Sox announced Wednesday that they’ve reinstated lefty Martin Perez from the 60-day injured list. Triple-A lefty Jared Shuster was designated for assignment to clear a spot on the 40-man roster. Reliever Cam Booser was optioned to Triple-A to open a spot on the active roster.
Perez has been out since April 18 due to a flexor strain. He pitched quite well through his first four starts (3.15 ERA in 20 innings) but wasn’t healthy enough to develop into a potential trade deadline chip, as the rebuilding White Sox probably hoped when signing him to a one-year, $5MM contract over the winter.
Perez pitched a combined 6 2/3 innings over a pair of minor league rehab starts and will now at least get the opportunity to eat some innings for the Sox down the stretch — all while looking to showcase his health for interested clubs in the offseason. Perez’s deal contains a mutual option, but it’s been more than a decade since both ends of a mutual option was exercised by team and player alike. He’s all but certain to become a free agent again in November.
Shuster, 27, was a first-round pick of the Braves back in 2020 (No. 25 overall). He came to the South Side by way of the 2023 Aaron Bummer swap — a deal that netted the Sox five players but was more of a volume play wherein Chicago picked up several former top prospects in hopes of turning a couple of them around. It hasn’t panned out. Braden Shewmake, Michael Soroka and Nicky Lopez have all since been cut loose. With Shuster now designated for assignment and perhaps on his way out the door, 25-year-old righty Riley Gowens is the most promising remnant of that return. He’s posted a 4.05 ERA through 100 innings in his second go-around at the Double-A level and is not ranked among the system’s 30 best prospects.
In his two seasons with the ChiSox, Shuster has made 51 appearances — all but six of them out of the bullpen — and pitched a combined 89 innings with a 4.96 earned run average. He’s fanned only 16.9% of his opponents and turned in a 9.4% walk rate. Both, particularly the strikeout rate, are worse than league average.
Shuster has been up and down this season. Between his frequent shuttling from Chicago to Charlotte (where the Sox’ Triple-A club plays) and a 15-day IL stint due to blisters on his pitching hand, he’s pitched just 22 1/3 innings in Triple-A and 15 1/3 frames in the majors. His minor league work this year has also been lackluster, evidenced by a 6.04 ERA. Shuster’s 19.8% strikeout rate and 6.6% walk rate in Charlotte are at least moderately more encouraging than his MLB rate stats, but he’s also averaged two homers per nine innings pitched in Triple-A this year.
Shuster will be out of minor league options next year, so he was always a long shot to stick on the roster into next year’s camp. With the trade deadline behind us, he’ll be placed on waivers within the next five days. Shuster hasn’t been outrighted in the past and doesn’t have three years of MLB service, so if he goes unclaimed he’ll stick with the White Sox via an outright assignment to Charlotte.
Mets To Promote Nolan McLean
The Mets will call up top pitching prospect Nolan McLean to make his MLB debut this Saturday, reports SNY’s Andy Martino. He’ll step into the rotation spot vacated by Frankie Montas‘ move to the bullpen. Jon Heyman of the New York Post reported earlier this morning that righty Paul Blackburn was also headed to the bullpen when he’s ready to be reinstated from the injured list, setting the stage for either McLean or fellow prospect Brandon Sproat to make his debut.
As we noted yesterday when the Mets moved Montas to the ‘pen, the Saturday start aligns far better with McLean’s turn in the Triple-A rotation than with that of Sproat. McLean has also simply outpitched Sproat this season, though both well-regarded prospects have excelled recently.
The timing of the move likely isn’t a coincidence. Saturday marks the first day on the calendar where there’s not enough time remaining for players to accrue enough service to exhaust their rookie eligibility. By waiting until Saturday to promote McLean, the Mets have ensured that he’ll still qualify as a rookie next season and therefore still be able to earn the Mets potential future draft picks via the league’s Prospect Promotion Incentive (PPI) program. In all likelihood, McLean is just one of several top prospects around the league who’ll be promoted after Aug. 15.
McLean, 24, was the Mets’ third-round pick in 2023. He’s rated as one of the system’s more promising young arms since that selection, but his stock has exploded in 2025 as he’s ripped through Double-A and Triple-A lineups. McLean has pitched a combined 113 2/3 innings between those two levels and compiled a tidy 2.45 ERA while punching out 27.2% of his opponents. His 10.7% walk rate is still too high, but his huge 54.7% ground-ball rate can help to erase a few of those free passes by way of the double-play ball.
This year’s terrific run has not only vaulted McLean toward the top of the Mets’ in-house prospect lists — it’s made him a consensus top-100 prospect in the sport. He sits 37th among all big league prospects at MLB.com, 40th at Baseball America and 53rd at FanGraphs on each outlet’s post-deadline reranking of the sport’s top young talents.
The 6’2″, 215-pound McLean is an Oklahoma State product whose athleticism draws plenty of praise. He was a two-sport star in high school, playing both baseball and football, and he was a two-way player at OSU, where he was a third baseman and outfielder in addition to his work on the mound. He’s since dialed in only on pitching and experienced an uptick in velocity, now sitting 95 mph with a four-seamer that can climb to 98 mph when he needs to reach back for a bit extra. MLB.com’s report on McLean calls his sweeper a “monster” of a pitch with “elite” spin rate. He’s sitting 85.5 mph with that pitch and also mixing in a sinker, cutter and seldom-used changeup.
Because McLean will retain rookie eligibility going into next year, he could earn the Mets a draft pick down the line. If McLean were to win National League Rookie of the Year or finish top-three in NL MVP voting next season, the Mets would gain that pick. Even if McLean doesn’t hit either of those goals, the fact that he’ll be a top-100 prospect who accrued a full year of service as a rookie opens a three-year window for him to net the Mets a compensatory pick based on award voting. If McLean were to land any top-three finish in Cy Young or MVP voting before reaching arbitration, the Mets would still gain a pick. Players can only net their team one pick under the league’s PPI program, but the timing of his promotion means McLean could do so at any point from 2026-28.
Setting aside the PPI aspect of the promotion, McLean’s promotion comes at a time when he cannot accrue a year of service this season. He’ll be controllable for at least six full years beyond the current campaign — potentially more than that, depending on whether he’s optioned at any point in the future. The earliest he could become a free agent would be after the 2031 season, and the earliest McLean could qualify for arbitration would be following the 2028 season.
Diamondbacks Sign Matt Mervis To Minor League Deal
Matt Mervis has found a new home after he was released by the Marlins earlier this month. The first baseman signed a minor league contract with the Diamondbacks today, according to his transaction log on MLB.com. He will report to the Triple-A Reno Aces. A lefty power bat, Mervis will slot in as a nice replacement for Seth Brown, who opted out of his minor league deal with the D-backs over the weekend.
The Cubs signed Mervis as an undrafted free agent in 2020. He got off to a slow start in 2021 but started mashing his way through the minors in 2022. He continued swinging a hot bat at Triple-A in 2023, earning his first MLB call-up that May. Unfortunately, he just couldn’t figure out big league pitching, a theme that continued in 2024 and again this year after the Cubs flipped him to the Marlins for Vidal Bruján. All told, in 261 plate appearances from 2023-25, he has hit .165 with a .560 OPS and a 53 wRC+. His 10 home runs are nothing to sniff at, but he has struggled to do damage when he hasn’t hit the ball out of the park, and he’s struck out more than one-third of the time.
There’s no denying how disappointing those MLB numbers are. Yet, perhaps the right organization can teach Mervis how to limit his strikeouts and tap into the prodigious power he has flashed in the minor leagues. In just over 1,800 minor league plate appearances, he’s hit 95 doubles and 95 home runs, good for a .517 slugging percentage and .250 isolated power. The Cubs and Marlins couldn’t help him reach his ceiling, but now the Diamondbacks will give it a shot.
Royals To Sign Nick Robertson To Minor League Deal
The Royals have agreed to a minor league contract with Nick Robertson, reports Ari Alexander of KPRC 2. The right-hander had spent most of the season in the Astros organization, but he was released today, according to the transaction log on his MLB.com player page.
Robertson, who recently turned 27, appeared in the majors for the Dodgers, Red Sox, Cardinals, and Blue Jays from 2023-24, pitching a total of 35 2/3 innings over 27 games. He struck out 40 while issuing just nine unintentional walks, but a high opponents’ batting average and six home runs led to a 5.30 ERA.
The Blue Jays held on to Robertson over the 2024-25 offseason but designated him for assignment on Opening Day. They then traded him to the Astros, and while he never earned a promotion to Houston, he stuck on the 40-man roster for the first four months of the year. Eventually, however, Robertson was DFA’d in the days leading up to the trade deadline, but he passed through waivers unclaimed, and the Astros sent him outright back to Triple-A Sugar Land.
Robertson has a 4.25 ERA but a 5.12 FIP in 36 Triple-A innings this year. Control has been an issue, as his 16.6% walk rate is the highest mark he’s posted at any level in any single season of his career. Yet, the Royals must have seen something they liked; perhaps it’s his 47.8% groundball rate, which has helped him limit his opponents to just three home runs in 157 trips to the plate. Indeed, Robertson has always done quite a good job of limiting home runs at Triple-A. In 127 innings dating back to 2022, he has only given up 12 long balls, a rate of one every 46.25 batters faced. While he hasn’t earned much MLB playing time, several organizations have been intrigued by his profile over the past two years. The Dodgers included him in their trade for Enrique Hernández at the 2023 deadline, and the Red Sox flipped him to the Cardinals the following winter as part of the return for Tyler O’Neill. The Angels, Blue Jays, and Astros have since acquired him, and now the Royals are the latest club interested in seeing what he has to offer.
Rays Place Taylor Walls On 10-Day IL With Groin Strain
The Rays have placed shortstop Taylor Walls on the 10-day injured list with a left groin strain, the team announced. In a corresponding move, outfielder Tristan Peters was recalled from Triple-A.
Walls has been Tampa Bay’s primary shortstop this year, with 77 starts and 94 appearances at the position. It was particularly noteworthy that he still got his fair share of starts at shortstop when both he and Ha-Seong Kim were healthy. Kim signed a two-year, $29MM deal with the Rays over the offseason (a sizeable deal by their standards) with the expectation that he would become the starting shortstop. While injuries have limited Kim to just 18 games this year, the fact that Walls has shared the position with Kim lately shows how highly the Rays must think of Walls’ defense. Indeed, Walls was scheduled to start at shortstop on Saturday before he was scratched from the lineup. Kim has since started at shortstop in each of the team’s last three games.
Manager Kevin Cash explained that Walls still felt “closer to 75% rather than 100%” before today’s matchup with the Athletics, so the team decided he needed “a couple days to let [his groin injury] continue to calm down” (per Marc Topkin of the Tampa Bay Times).
Tampa Bay will be just fine in the middle infield in Walls’s absence. Kim can play shortstop full-time (with Tristan Gray around as a backup), and All-Star Brandon Lowe can return to playing second base on a daily basis. Lowe had recently started a handful of games at first base and DH to make room for Kim at second base when Walls was starting at short. The problem is that with Lowe at second base and Yandy Díaz at first, the Rays are left without a good option to DH. All-Star Jonathan Aranda is on the IL with a broken wrist (hence Díaz’s return to first base). He remains hopeful he’ll return this season (per MLB.com’s Joey Johnston), but it’s far from a guarantee. For as long as Aranda is out of the equation, the Rays are at their best with Walls and Kim sharing middle infield duties while Lowe and Díaz cover first base and DH. They have not yet offered a timeline for Walls’s return, but they will hope his groin strain proves to be minor.
Entering play today, the Rays are 5.5 games back of the last AL Wild Card spot. They’re a talented team, with a +43 run differential that is far more impressive than their sub-.500 record. However, they’re running out of time to make a comeback. Both FanGraphs and PECOTA have their postseason odds below 5%. With Aranda out indefinitely and Shane McLanahan officially done for the season, they can’t afford for much else to go wrong.
