Chasen Shreve Elects Free Agency
Left-hander Chasen Shreve, who was recently designated for assignment by the Rockies, rejected an outright assignment and elected free agency, per the MLB.com transactions log. He’s back on the open market.
Shreve, 34, only pitched one inning with the Rockies. He retired all three hitters he faced on a trio of grounders. It was just one inning, but that frame now gives Shreve a stretch of 11 consecutive seasons pitching in the big leagues in some capacity. Though he hasn’t gotten much of a look in the majors this year, Shreve has been pitching well in Triple-A. He’s spent time in the Yankees’ and Rangers’ systems as well, totaling 34 1/3 innings with a 2.62 earned run average, 26.7% strikeout rate, 9.2% walk rate and 41.5% ground-ball rate.
Of course, Shreve has a lengthy big league track record and has been effective more often than not in the majors. He’s tallied 357 MLB frames dating back to 2014 and pitched to a career 3.96 ERA that’s supported by a 3.87 SIERA. Shreve’s career strikeout, walk and ground-ball rates (25.2%, 10.8% and 41.9%, respectively) more or less closely mirror the marks he’s demonstrated in Triple-A this season. He pitched just two innings with the 2019 Cardinals and had a tough 26-inning run with the 2022 Mets (6.49 ERA) but has otherwise been a serviceable middle-innings arm who can capably be relied upon to hold opponents to around four runs for every nine innings pitched.
Shreve is hardly an elite arm, but he’s an experienced lefty who’s pitched in a variety of roles and could help a contending club down the stretch. Any team that signs him would be able to carry him on the postseason roster so long as he’s in the organization prior to Sept. 1. The Mets, Cubs and Mariners are among the teams who currently have only one southpaw in their big league bullpen, although Shreve could certainly latch on with an organization that has more left-handed bullpen depth than that.
White Sox Planning More Consistent Roles For Dominic Fletcher, Miguel Vargas
The White Sox have gutted their roster over the past season as their rebuild has gone into full swing, but they’ll aim for some more consistency down the stretch in 2024. Outfielder Dominic Fletcher and infielder/outfielder Miguel Vargas will have more solidified roles down the stretch. James Fegan of Sox Machine tweeted recently that interim manager Grady Sizemore wants to give Vargas a consistent role (something he’s previously not had with the Dodgers), so he’ll play primarily at third base. Sizemore also said he plans to deploy Fletcher in a near-everyday role after he’s been heavily platooned prior to this point (X link via Daryl Van Schouwen of the Chicago Sun-Times).
Fletcher, 26, came to the Sox in an offseason deal that sent pitching prospect Cristian Mena to the Diamondbacks. His plus contact skills and solid glovework seemingly give him a high floor in the outfield corners, but Fletcher floundered through 66 plate appearances in the White Sox’ first 23 games and found himself quickly optioned to Triple-A Charlotte. He returned in mid-May, collected one hit in 18 plate appearances, and then hit the injured list with a shoulder strain.
The Sox sent Fletcher on a rehab assignment and optioned him afterward. He hit well in his last run with Triple-A Charlotte, was recalled to the big leagues the evening prior to the trade deadline, and now stands to log an everyday role down the stretch. He’s making the most of it in his tiny sample thus far; after hitting .283/.345/.377 in 53 Triple-A trips to the plate following his rehab stint, he’s tallied 27 plate appearances in the big leagues and gone 9-for-26 with a double, a walk and only three strikeouts. It’s a minuscule set of games, of course, but it’s still the most encouraging run Fletcher has had since landing in Chicago.
“I love Dom’s game,” Sizemore told the Sox beat (via Van Schouwen). “He’s a good all-around player, especially the defense.”
Fletcher hasn’t shown that yet with the South Siders, but he did slash .301/.350/.441 in 102 plate appearances with the Diamondbacks in 2023’s MLB debut. He’s also a lifetime .293/.376/.462 hitter in 889 turns at the plate in Triple-A, where he’s fanned in a lower-than-average 18.6% of his plate appearances and drawn walks at a stout 10.6% rate.
Fletcher has also drawn strong defensive marks in limited time. He’s played only 487 innings in the outfield in his big league career but been credited with plus marks in Defensive Runs Saved (7) and Outs Above Average (3). When looking at only his corner work (200 innings), both DRS (5) and OAA (5) feel he’s been even stronger. Again, it’s not a big sample, but scouting reports on Fletcher have been bullish on his glove for some time now. Prior to the season, Baseball America called him a potential plus defender at all three positions, noting that his “great reads and above-average routes … and above-average arm strength” all help to offset his roughly average speed.
As for Vargas, his time with the Sox has gotten out to a rough start after being acquired in the Erick Fedde/Michael Kopech deal. Recently fired skipper Pedro Grifol has played him at third base, designated hitter and in left field, but Sizemore seems keen to keep him at the hot corner moving forward. Still just 24 and only a season removed from ranking among the sport’s top 40 overall prospects, Vargas has batted .116/.240/.209 in 50 plate appearances. He’s at least shown good strike zone recognition, drawing seven walks (14%) and chasing only 19.8% of pitches off the plate — way shy of the 28.5% league average. Earlier this season, it didn’t take a much longer slump than this for the Sox to option Fletcher earlier, but it seems they’re understandably intent on giving Vargas some more time to work through his big league struggles.
After all, there’s little left for Vargas to prove in the minors. He’s a .297/.412/.512 hitter in 997 Triple-A plate appearances, including a huge .290/.440/.556 batting line there in 2024. The White Sox already know Vargas can clobber upper-minors pitching, and the focus will now shift on coaxing improvements from the talented youngster at the MLB level. With the Dodgers, they bounced Vargas from third base, to second base, to first base, to left field in an effort to get his touted minor league bat into a veteran-laden lineup where Vargas was largely blocked from a regular role. He’ll have a much clearer runway to playing time at Guaranteed Rate Field — and at his natural position, no less.
There’s minimal competition for either player at the moment. In the outfield, Fletcher has been lining up in right field alongside center fielder Luis Robert Jr. and left fielder Andrew Benintendi. Oscar Colas hasn’t hit well in Triple-A or the majors this season. Corey Julks hasn’t hit much in the majors, either. Zach DeLoach, acquired from the Mariners in the Gregory Santos deal, has roughly league-average numbers in Triple-A.
It’s a similar story for Vargas at third base. Former top prospect Nick Senzel hasn’t hit with the Nationals or White Sox this season and will likely be non-tendered in the offseason. Lenyn Sosa has seen some time at third base but is a utility player in a best-case scenario. Bryan Ramos, who entered the season as one of Chicago’s top prospects, has taken a huge step back in 2024 after a breakout 2023 season in Double-A. With a strong finish, both Fletcher and Vargas could essentially stake their claim to regular jobs on what should be a largely wide-open White Sox roster in 2025.
Carl Edwards Jr. Elects Free Agency
Veteran right-hander Carl Edwards Jr. rejected an outright assignment from the Padres following his recent DFA and instead elected free agency, per the transaction log at MiLB.com. He can now sign with any club.
Edwards returned to the Padres on a minor league deal earlier this summer — his second career stint with the organization. The 32-year-old (33 next month) made only one appearance with San Diego this time around, however, and allowed all three runners he faced to reach base (two walks, one hit). He wound up being lifted from the game and bailed out when teammate Yuki Matsui induced a grounder to escape the bases-loaded jam created by Edwards.
Though his lone MLB look wasn’t sharp, Edwards has had a decent year in Triple-A. He’s split the season between the top affiliates for the Cubs and Padres, pitching to a 3.30 ERA with a 22.2% strikeout rate but a grisly 14.3% walk rate. He’s worked both out of the bullpen and, more recently, out of the Padres’ Triple-A rotation, so he’s stretched out for multiple innings.
Prior to this season, the well-traveled Edwards spent the 2022-23 seasons with the Nationals and pitched well out of manager Davey Martinez’s bullpen. In 93 2/3 innings, he tallied a 3.07 ERA — albeit with shaky rate stats (20% strikeout rate, 10.6% walk rate). A stress fracture in Edwards’ right shoulder ended his 2023 campaign prematurely and limited him to a minor league deal this past offseason. That deal came with the Cubs, but Edwards triggered a June opt-out in that contract after he hadn’t been added to the big league roster and signed a minor league deal with the Padres.
Once a top prospect in the Rangers’ system who went from Texas to the Cubs as part of a prospect package for starter Matt Garza, Edwards has now pitched in parts of 10 big league seasons. He’s logged a total of 280 innings spread across six clubs, with the bulk of his work coming for the Cubs and Nats. Edwards carries a 3.54 ERA with a hearty 28.1% strikeout rate and bloated 12.7% walk rate in the majors.
Nationals Release Harold Ramirez
August 14: Washington announced on Wednesday that they’ve placed Ramirez on unconditional release waivers.
August 13: The Nationals announced that they have selected the contracts of infielder Andrés Chaparro and right-hander Orlando Ribalta, two moves that were previously reported. In corresponding moves, they designated infielder/outfielder Harold Ramírez and right-hander Jordan Weems for assignment.
Ramirez, 29, enjoyed a pair of productive seasons with the 2022-23 Rays, hitting a combined .306/.348/.432 in 869 trips to the plate, but he stumbled badly out of the gates in 2024 and yet to recover. The righty swinger posted a nice .268 batting average in 169 plate appearances with Tampa Bay but couldn’t couple that with any on-base or extra-base value; he managed only a .284 OBP and slugged just .305. Ramirez was designated for assignment on June 7 and released after no team wanted to acquire/claim the remainder of his $3.8MM salary.
Following his release, Ramirez signed a minor league deal with the Nats and was back in the majors just a couple weeks after his release. He’s appeared in 25 games with Washington but hasn’t fared much better at the plate, hitting .243/.273/.365 in 77 plate appearances. The rebuilding Nationals will now use his roster spot to take a look at the younger Chaparro — another right-handed bat that they acquired in the deadline trade sending reliever Dylan Floro to Arizona.
Weems, 31, has been a regular presence in the Washington bullpen since 2022. He’s piled up 136 innings as a Nat but logged a combined 5.03 ERA in that time. Weems sandwiched an impressive 2023 showing between a pair of lackluster seasons in 2022 and 2024. He’s pitched 41 2/3 innings this season but been rocked for a 6.70 ERA with a career-low 17.9% strikeout rate and a career-worst 12.2% walk rate (excluding the 20% walk rate he notched in 5 2/3 innings back in 2021).
Weems reached three years of big league service in 2024 and is out of minor league options. That means the Nats would’ve had to tender him a raise in arbitration this winter and carry him on the big league roster to begin the 2025 season. They’ll instead move on from the right-hander and, as with Ramirez, turn that roster spot over to a more youthful option who’s posted some interesting numbers in the minors this year.
With the trade deadline now behind us, the Nationals’ only course of action with Ramirez and Weems will be to place them on either outright waivers or release waivers. The other 29 clubs will all have a chance to claim them. (Ramirez’s salary is still being paid by the Rays, so he’d only cost a new team the prorated league minimum.) Both will have the right to reject the assignment in favor of free agency, by virtue of their MLB service time.
Dodgers’ River Ryan To Undergo Tommy John Surgery
The Dodgers announced Tuesday that top pitching prospect River Ryan will undergo Tommy John surgery. He’ll miss the remainder of the 2024 season and quite possibly all of the 2025 campaign while recovering. Ryan, who posted a 1.33 ERA through his first four big league starts, hit the injured list over the weekend after suffering a UCL sprain in his most recent start.
Ryan’s 2024 season was already known to be over, but the Tommy John procedure marks a worst-case scenario in the wake of his UCL injury. An internal brace procedure might’ve come with a shorter timeline for recovery, but he’ll require a full ligament replacement, which tends to shelve pitchers for upwards of 14 months. Every rehab process is different, and there’s always a chance Ryan might heal a bit faster than the standard pitcher, but a 12-month recovery is typically an absolute minimum for pitchers who require Tommy John surgery.
The 25-year-old Ryan was an 11th-round pick by the Padres in 2021. He went to the Dodgers in a trade that now looks like a heist, sending first baseman/outfielder Matt Beaty back to San Diego. (Beaty played in 20 games with the Padres and hit .093/.170/.163 before being cut loose.) Ryan hadn’t even made his professional debut at the time and had signed for a $100K bonus, so he was hardly a high-end prospect. Ryan simply getting to the majors would’ve been a player development success story for Los Angeles, but he instead ascended to the point where he’s regarded as one of the top pitching prospects in the sport. Ryan climbed as high as No. 21 overall on FanGraphs’ top-100 prospect rankings and sits 99th on MLB.com’s top-100 list at the moment.
The reasoning behind that rise isn’t especially difficult to see. Ryan spent the majority of the 2023 season in Double-A and pitched to a tidy 3.33 ERA in 97 1/3 frames before being bumped to Triple-A late in the year. He was hit hard in those two starts but returned to Triple-A this year and carved up opponents with a 2.76 ERA, 28.8% strikeout rate and 9.1% walk rate in five starts. He was limited in the minors this season due to a shoulder injury, but Ryan graduated to the majors with a 3.22 ERA, 28.5% strikeout rate and 10% walk rate in parts of three professional seasons since being traded to the Dodgers organization.
Ryan becomes the latest Dodgers hurler to land on the injured list in what’s been a trying season for their rotation depth. Los Angeles entered the year with Clayton Kershaw on the injured list and knowing that Tony Gonsolin would miss most/all of the season recovering from last summer’s Tommy John surgery. They’ve since seen Emmet Sheehan (Tommy John surgery) and Dustin May (esophageal surgery) fall to season-ending surgeries, while Yoshinobu Yamamoto (strained rotator cuff) and Walker Buehler (hip and elbow) land on the shelf with long-term injury troubles of their own. Prospects Nick Frasso (shoulder surgery) and Kyle Hurt (Tommy John surgery) are on the minor league injured list and done for the year as well. Last year’s breakout right-hander, Bobby Miller, has made just seven MLB starts and been ineffective both with the Dodgers and with Triple-A while navigating a shoulder injury of his own.
With that laundry list of injuries, the Dodgers currently have a rotation that includes Kershaw, Tyler Glasnow, Gavin Stone and deadline pickup Jack Flaherty. Buehler is expected to return from the injured list later this week, but he’s been bludgeoned for a 5.84 ERA in eight big league starts and has a 5.01 mark in another eight Triple-A starts this season — his first year back from 2022 Tommy John surgery. He offered a glimmer of hope in his most recent rehab start, tossing 5 1/3 innings and holding the Rangers’ Triple-A club to one run on one hit and three walks with five punchouts.
Because Ryan’s injury occurred while pitching at the big league level, he’s on the MLB injured list and will spend his 2025 rehab on the big league injured list as well. He’ll earn major league pay and service time while recovering from the injury. That’ll give him at least a full year of service while he recovers, putting him on track for arbitration in the 2027-28 offseason and free agency following the 2030 season. Of course, future optional assignments could change one or both of those trajectories, and for now the immediate focus will simply shift to the long process of getting the talented young righty back to full strength with an eye toward a late-2025 or early-2026 return.
Rockies Outright John Curtiss
Rockies right-hander John Curtiss went unclaimed on waivers and was assigned outright to Triple-A Albuquerque, per the team’s MLB.com transaction log. He has the right to reject that assignment in favor of free agency. If he accepts, he’ll stick with the Rox organization in Triple-A but no longer occupy a spot on the 40-man roster.
Curtiss signed a minor league deal with Colorado over the winter, was selected to the big league roster in May, and rejected an outright assignment after being designated for assignment. He’s since returned on an additional pair of minor league deals — opting out once along the way — and was selected back to the big league roster in late July. He’s pitched 2 1/3 MLB innings this year and been tagged for four runs. His Triple-A work has been vastly better. In an extremely hitter-friendly setting, he’s posted 38 innings of 4.03 ERA ball with a sub-par 18.5% strikeout rate against a strong 7.4% walk rate.
The Rockies are the seventh big league team for which the journeyman Curtiss has pitched. He’s amassed 108 2/3 innings in the majors and sports a lifetime 4.06 ERA with a roughly average 22.7% strikeout rate and sharp 7% walk rate. He was at his best in 2020-21 when he pitched 69 1/3 frames with a 2.86 earned run average, 24.1% strikeout rate and 5.2% walk rate between the Rays, Marlins and (much more briefly) Brewers. Milwaukee acquired Curtiss from Miami at the 2021 trade deadline, but he pitched just 4 1/3 innings before requiring Tommy John surgery.
James Paxton Diagnosed With Partially Torn Calf
3:10pm: Manager Alex Cora tells the Sox beat that Paxton is a “long shot” to return in 2024 (X link via MLB.com’s Ian Browne). The skipper added that Criswell, once healthy, will rejoin the rotation as the team’s fifth starter (X link via MassLive.com’s Chris Cotillo).
2:30pm: Red Sox left-hander James Paxton tells reporters that he’s been diagnosed with a partial tear of his right calf muscle (X link via WEEI’s Rob Bradford). The veteran southpaw acknowledged that it could sideline him for the remainder of the year but will still try to rehab in an effort to make it back before the season concludes.
The Sox placed Paxton on the 15-day injured list with a calf strain yesterday. The term “strain” itself, by definition, indicates there is a degree of stretching or tearing, so today’s announcement isn’t a total surprise. That said, the fact that he’s possibly facing an absence of six-plus weeks indicates that it’s a tear of some note — the latest in a long line of injuries that have plagued the talented left-hander throughout his big league career.
Paxton, 35, spent the 2022-23 seasons in Boston. He missed the entire ’22 campaign due to Tommy John surgery but returned in 2023 to pitch 96 innings of 4.50 ERA ball with more promising strikeout and walk rates. The Dodgers signed him to a one-year, $7MM deal with incentives that could take the contract up to $13MM. He unlocked all of those incentives before being designated for assignment and traded to the Red Sox in return for minor league infielder Moises Bolivar.
The Sox hoped that Paxton would help shore up an injury-depleted starting rotation, but it’s now possible they’ll receive only three starts from him. Paxton notched a solid 4.09 ERA in his 11 innings following the trade but exited his third and potentially final start after recording just two outs. He was Boston’s lone veterean acquisition prior to the trade deadline, meaning the Sox will again be left to rely on the quartet of Tanner Houck, Kutter Crawford, Brayan Bello and Nick Pivetta, with scant depth behind the group. Righty Cooper Criswell has pitched well but has little track record and is currently out with Covid-19. Fellow righty Josh Winckowski has also made a handful of starts and could see further action down the stretch.
Paxton’s injury could open the door for young Quinn Priester, whom the Sox acquired from the Pirates in exchange for infield prospect Nick Yorke. Priester, a former first-round pick and top prospect, has yet to establish himself as a consistently viable big league starter. He’s logged a 6.46 ERA in 94 2/3 big league innings to this point in his young career, but the 23-year-old has generally fared well in the upper minors — an ugly two-game stint with the Sox’ Triple-A club in Worcester notwithstanding.
It’s a tenuous situation in Boston — one that would blow up in particularly bad fashion were one of Houck, Crawford or Pivetta to go down with an injury of note. Boston traded Chris Sale to the Braves in a regrettable offseason swap that netted infielder Vaughn Grissom. He was “replaced” by right-hander Lucas Giolito, who required season-ending internal brace surgery before the 2024 campaign began. Righty Garrett Whitlock had his own internal brace operation back in May. Depth arms like Chris Murphy and Bryan Mata have also been non-factors this season due to injury.
The Red Sox currently sit in third place in the AL East despite a strong 62-55 record. They’re only two games back in the American League Wild Card hunt, landing .001 percentage points ahead of the 63-56 Mariners but trailing the 65-54 Royals for the final Wild Card spot.

Astros Release Dylan Coleman
The Astros have released right-hander Dylan Coleman after designating him for assignment last week, as indicated on the team’s transaction log at MLB.com. He’s now a free agent.
Coleman, 28 next month, was acquired from the Royals in a small December swap and has spent the bulk of the season in Triple-A Sugar Land. He pitched one scoreless big league frame for Houston back on April 3 but has limped to a more problematic 6.50 earned run average in 36 Triple-A frames. He’s been on a particularly rocky run of late, yielding 12 runs (11 earned) on eight hits and nine walks over his past 5 2/3 innings. That recent slide surely played into the decision to designate the former fourth-rounder (Padres, 2018) for assignment.
As recently as 2022, Coleman looked well on his way to establishing himself in the Royals’ big league bullpen. He made his MLB debut late in the 2021 season and in 2022 piled up 68 innings of work. In a total of 74 1/3 innings from ’21-’22, he notched a very sharp 2.66 ERA while fanning 24.8% of his opponents. His 12.1% walk rate was in need of improvement, but Coleman sat 97.7 mph with his heater, picked up swinging strikes at an impressive 13% clip, avoided hard contact (86.4 mph average exit velocity, 6.3% barrel rate, 35.9% hard-hit rate) and did a good job keeping the ball in the yard (0.61 HR/9).
That success deteriorated quickly in 2023, however. Coleman was rocked for an 8.84 ERA in 18 1/3 big league innings and walked 19 batters in that time. The command troubles continued in Triple-A Omaha, where he issued a free pass to a calamitous 21.8% of his opponents. The right-hander’s average fastball also plummeted from the prior season’s 97.5 mph to 95.2 mph in the majors (and 96.1 mph down the stretch in Triple-A).
All of those problems have persisted, if not worsened, following the change of scenery. Coleman walked 23.9% of his opponents with Sugar Land in the Astros organization, and Statcast measured his average heater in Triple-A this season at 95.7 mph — well shy of his 2021-22 levels. Whatever the reason for the downturn in command and velocity, the 2023-24 version of Coleman looks like a decidedly different pitcher than the reliever who showed quite a bit of promise from 2021-22.
Coleman’s prior track record, minimal acquisition cost — he’ll very likely require only a minor league deal to sign — and remaining club control (under two years of MLB service) should be enough to spark interest from a new club, whether that’s in the coming days/weeks or in the offseason.
Brad Keller Elects Free Agency
Red Sox right-hander Brad Keller has elected to become a free agent, reports Alex Speier of the Boston Globe. As a player with five-plus years of big league service, Keller must consent to being optioned to the minors. He agreed to be optioned once earlier this season, but when the Red Sox sought to option him earlier this week, he instead exercised his right to become a free agent and seek a new opportunity.
Keller, 29, was a fixture in the Royals’ rotation from 2018-23. One of the more successful Rule 5 picks in recent memory — Kansas City plucked him out of the D-backs’ organization in the 2017 Rule 5 Draft — he enjoyed three sharp seasons as a starter for the Royals before struggling repeatedly from 2021-23, often due to injuries. After logging a 3.50 ERA in 360 1/3 innings for K.C. from 2018-20, Keller was roughed up for a 5.14 mark in the three subsequent seasons. Things went way off the rails in 2023, when he walked 45 hitters in 45 1/3 innings before going on the injured list and eventually undergoing thoracic outlet surgery.
The White Sox signed Keller to a minor league deal over the winter, and he had a brief run with Chicago before being designated for assignment and electing free agency. The Red Sox scooped him up in late May. After a tough debut in Baltimore, he settled in to pitch well over a string of eight long-relief appearances, but Boston sent him to the minors in late June (a move he approved at the time). He was recalled on Friday, surrendered three runs in four innings against the Astros on Saturday, and was optioned back to Triple-A Worcester on Monday — this time exercising his right to become a free agent.
Overall, Keller has pitched 37 1/3 innings between the ChiSox and BoSox this season. He’s logged a discouraging 5.30 ERA in that time, but his season isn’t without its silver linings. First and foremost, the disastrous command issues he displayed last season have come back down to Earth. In fact, Keller has not only put last year’s ghastly 21.3% walk rate behind him — he’s sporting a career-low 7.7% walk rate in his 37 1/3 frames. His 17.8% strikeout rate is below the league average but is right in line with the 17.4% mark he posted prior to his TOS-ruined 2023 season. Keller has seen the velocity on his four-seamer and sinker tick up slightly (though he’s also primarily been working in relief, so that’s not necessarily due to better health), and this year’s 9.1% swinging-strike rate is the second-best mark of his career (but still worse than league-average).
Down in Triple-A, things have gone better. He’s pitched a nearly identical slate of 38 innings there and has similar walk and strikeout rates to the ones he’s posted in the majors. However, he’s sporting a 4.26 ERA that’s more than a full run lower than his MLB ERA, due largely to the fact that he’s been able to avoid the long ball in a way he hasn’t at the MLB level (0.24 HR/9 in Triple-A, 1.93 HR/9 in MLB). In all likelihood, his home run rate in the majors is due for some positive regression, while his home run rate in the minors is likely due to swing the other direction.
For a team needing some late-season rotation depth or length in the bullpen, the veteran Keller could be a worthy flier. The Twins, Astros, Guardians, Mets, Braves and Padres are among the postseason hopefuls who have incurred injuries or are experiencing notable workload concerns among their current crop of starting pitchers.
