Braves Release Kyle Nelson
The Braves have released left-hander Kyle Nelson, according to the transactions log at MLB.com. He had been with the organization on a non-roster deal.
Nelson made sense as a potential depth piece for Atlanta. He has a serviceable 4.34 ERA in 116 big-league innings dating back to 2020. He has struck out 23.1% of opposing hitters while walking 9.0% of them. Most of the strikeouts came in 2023 with the Diamondbacks, when he pitched a career-high 56 innings with a 4.18 ERA. In every other season, he has run a sub-20% strikeout rate. Nelson’s numbers fell off a bit in 2024, and he missed most of that season recovering from thoracic outlet surgery. Though he returned in 2025, he was designated for assignment in early July and sent outright to Triple-A. He only pitched two innings over three appearances with Arizona in 2025, electing free agency after the season.
Nelson made just one appearance in the Braves’ big-league camp, allowing one earned run in one inning against the Red Sox on March 17. He clearly faced an uphill battle to make the Braves’ season-opening bullpen. Raisel Iglesias and Robert Suarez will handle the late innings. Meanwhile, the club has three lefties in Dylan Lee, Aaron Bummer, and Jose Suarez to cover the middle innings and long relief. Lee has been excellent in the last two years with a 2.74 ERA and a 23.9% K-BB rate. Bummer is one of the game’s best at inducing groundballs, while Jose Suarez impressed with a 1.86 ERA in a limited sample last year.
For now, Nelson will return to the market and look for a club to take him on as minor-league depth. Though he has been in the league since 2020, he is still younger than 30 and can be controlled through 2028 via arbitration. If he can work his way back to the majors, he can also provide roster flexibility through his one remaining option year.

Braves Sign Kyle Nelson To Minor League Deal
The Braves have signed left-hander Kyle Nelson to a minor league deal, according to Matt Eddy of Baseball America. It’s unclear if the Beverly Hills Sports Council client will be in major league or minor league camp.
Nelson, now 29, had his best stretch in the majors in 2022 and 2023. He tossed 93 innings for the Diamondbacks over those two seasons, primarily as a reliever though with a few starts as an opener. He allowed 3.39 earned runs per nine frames in that time, with a 24.9% strikeout rate and 7.2% walk rate that were both a bit better than league average.
Unfortunately, he hasn’t been at that level since. He required thoracic outlet syndrome surgery in April of 2024 and missed most of that season. He was back on the mound in 2025 but with diminished stuff and results. His fastball averaged around 92 miles per hour in 2022 and 2023 but was down to around 90 mph last year. He was mostly kept in the minors. He only made three big league appearances and posted an ugly 9.09 ERA in Triple-A. The Snakes outrighted him off the roster in July. He was selected back to the roster in August but was outrighted again in November. He elected free agency after that second outright.
For Atlanta, there’s no harm in bringing Nelson aboard via a non-roster pact. They project to have Dylan Lee and Aaron Bummer as their top two lefty relievers. José Suarez may be in the bullpen but likely as a long reliever/swingman. Dylan Dodd and Hayden Harris are on the 40-man but they are optionable and still have fairly limited big league track records, so they may oscillate between Triple-A and the majors this year. If Nelson can get back on track and onto the roster, he still has one option season remaining.

12 Diamondbacks Players Elect Minor League Free Agency
TODAY: Pope, Curtiss, Kelly, Nelson, and Kaiser all elected minor league free agency, according to the Reno Aces’ official transactions page. In addition, Matt Mervis, Cristian Pache, Matt Foster, and Tristin English also elected free agency. Of that quartet, only English (a third round pick for Arizona in the 2019 draft) received any big league playing time with the D’Backs in 2025, and the others were in the organization on minor league contracts.
NOV. 6: The Diamondbacks have announced a handful of roster moves. Infielder Ildemaro Vargas, catcher James McCann, and left-hander Jalen Beeks have elected free agency. Right-handers Austin Pope, John Curtiss, and Casey Kelly, left-hander Kyle Nelson, and infielder Connor Kaiser were outrighted off the 40-man roster. Arizona’s 40-man roster now sits at 38 players.
Vargas just wrapped up his third stint with the team. The versatile utilityman debuted with the Diamondbacks in 2017. After playing a minor role across three seasons, Arizona designated him for assignment in 2020. The DFA led to a trade to the Twins, though Minnesota would also designate Vargas for assignment less than a month after acquiring him. The Cubs scooped him up off waivers for the final month of the season. Vargas went through a similar set of transactions in 2021, just in a different order. He was claimed off waivers by the Pirates in May, then designated for assignment a couple of weeks later. Pittsburgh worked out a trade that sent Vargas back to Arizona.
Washington gave Vargas his longest look to date. The Nationals signed him as a minor league free agent in May of 2022. He hit .280 in 53 games with the team. Washington gave Vargas semi-regular playing time over the next two seasons. He topped 300 plate appearances for the first time in 2024. Vargas signed a minor league deal to return to Arizona this past offseason. He appeared in 38 games with the team in 2025. Vargas has spent time at all four infield positions, plus left field and right field. He’s also made five appearances in mop-up duty on the mound, hilariously allowing just two earned runs in five innings. The 34-year-old’s extreme versatility could get him another gig this offseason.
Arizona added McCann after Atlanta cut him loose in June. He appeared in 42 games for the team, filling in behind the plate after Gabriel Moreno went down with a hand injury. The 34-year-old posted a solid 110 wRC+ in limited action.
Beeks ended up being a decent find for the Diamondbacks. They signed him just before the season began, and the veteran lefty contributed a 3.77 ERA over 57 1/3 innings. Beeks missed time with a back injury, but still managed to make 61 appearances, including two as an opener.
Curtiss is the only member of the DFA group to make a significant impact at the MLB level in 2025. He appeared in 30 games with the big-league club, recording a 3.93 ERA. Curtiss has bounced around frequently since debuting in 2017, pitching for eight different teams.
Nelson has been a part of Arizona’s bullpen in recent years, but he only appeared in three games this past season. Pope debuted in September, making a two-inning appearance against the Dodgers before heading back to Triple-A Reno. Kelly pitched in two games in August. Kaiser had a couple of brief stints with the big-league club, going 2-for-18 across 11 games.
Diamondbacks Select Casey Kelly, Transfer Kevin Ginkel To 60-Day IL
The Diamondbacks announced today that right-hander Casey Kelly has been selected to the roster. Left-hander Kyle Nelson has been optioned to Triple-A Reno to open an active roster spot. In a corresponding 40-man move, righty Kevin Ginkel has been transferred to the 60-day IL.
Kelly, 35, signed a minor league deal with the Snakes back in March. He has been pitching for Triple-A Reno in a swing role since then, logging 85 innings over 14 starts and four relief appearances. He has a 5.82 earned run average with a 10.6% strikeout rate, 8.6% walk rate and 45.8% ground ball rate.
The Arizona bullpen got a workout last night. They played 11 innings against the Padres, eventually falling 10-5. Six different relievers made an appearance. They also traded Merrill Kelly ahead of the deadline last week, which led to Anthony DeSclafani moving from a long relief role into the rotation. DeSclafani only lasted two and a third innings last time out and is starting again tonight. Kelly could be tasked with absorbing some innings out of the bullpen behind DeSclafani, in order to spare the rest of the bullpen.
As for Ginkel, this move ends his season. He began the year on the injured list due to shoulder inflammation. He was activated off the IL at the end of April but landed back there on Monday due to a sprain of that shoulder. The 60-day count will push into early October.
He has some good seasons on his résumé but 2025 will go down as one of his worst. He posted a 7.36 ERA this year, perhaps with the shoulder troubles contributing to his struggles. He averaged 94.9 miles per hour on his fastball this year, more than a mile below last year’s 96 mph.
He is making $2.425MM this year and could be retained via arbitration for 2025. His poor results will prevent him from earning a notable raise but the Diamondbacks might consider a non-tender anyway, based on this year’s results. They will have to decide if they think there’s a path back to his pre-2025 results. From 2022 to 2024, he pitched 164 2/3 innings with a 2.95 ERA, 26.5% strikeout rate, 7.3% walk rate and 47.1% ground ball rate.

Diamondbacks Select Kyle Nelson, Connor Kaiser
The Diamondbacks announced Friday that they’ve selected the contracts of lefty Kyle Nelson and shortstop Connor Kaiser from Triple-A Reno. Arizona also reinstated veteran reliever Jalen Beeks from the injured list. First baseman Tyler Locklear, acquired in the Eugenio Suárez trade, was added to the major league roster. Lefty Brandyn Garcia (acquired in the Josh Naylor deal) and infielder Tristin English were optioned to Reno.
Nelson, 29, was a key member of Arizona’s bullpen in 2022, tossing 37 innings with a 2.19 ERA in his first year after coming over from Cleveland. His numbers dipped in 2023-24, however, and Nelson was removed from the 40-man roster in early July by way of a DFA. He passed through waivers unclaimed. In 22 2/3 innings for Reno this year, he’s been roughed up for a 6.35 ERA thanks to a whopping seven home runs allowed. Most of those struggles came earlier in the year, however. He’s rattled off 6 1/3 shutout innings over his past eight appearances.
Kaiser, 28, provides a glove-first infielder off the bench. He’ll work in a utility capacity as Blaze Alexander, who had been the depth infielder, will get everyday third base run with Suárez out the door. A Vanderbilt product, Kaiser is hitless in four career major league plate appearances. Those came over three games with the Rockies two seasons ago. He’s batting .236/.346/.423 in a hitter-friendly Triple-A setting this year.
Diamondbacks Outright Kyle Nelson
The Diamondbacks have sent left-hander Kyle Nelson outright to Triple-A Reno, according to his transactions tracker at MLB.com. That indicates he cleared waivers after being designated for assignment last week.
Nelson, 28, has the right to elect free agency but probably won’t exercise that right. Players with at least three years of service time have the right to reject outright assignments. However, if they have less than five years of service, they have to forfeit any remaining salary commitments in order to do so. Nelson is in that three-to-five window. He and the Snakes avoided arbitration in the offseason by agreeing to a salary of $825K for this year, a bit above the $760K major league minimum. He presumably wants to keep collecting that salary for the rest of the year and will therefore report to Reno.
A few years ago, the southpaw was a solid piece of the Arizona roster. In 2023, he tossed 56 innings for the Diamondbacks with a 4.18 earned run average. He paired a 28% strikeout rate with a 5.9% walk rate.
Unfortunately, he required surgery to correct thoracic outlet syndrome early in 2024, which put him on the shelf for most of that season. He’s back on the mound here in 2025 but his results haven’t been great so far. The Snakes have kept him on optional assignment and he has tossed 17 Triple-A innings with an ERA of 8.47. His 14.6% strikeout rate and 9.8% walk rate at that level are both clear downgrades from his major league work of a few years ago, with diminished velocity as well.
Given the uncertainty there, it’s unsurprising that no club put in a claim. Assuming Nelson accepts his assignment, he’ll try to get back on track with Reno. Perhaps he can regain some velocity and some better results as he moves further away from his surgery. If he’s not added back to the roster by the end of the year, he’ll be able to elect minor league free agency, as is the case for all players with at least three years of service who are removed from a 40-man roster during a season.

Diamondbacks Designate Kyle Nelson For Assignment
The Diamondbacks announced that left-hander Kyle Nelson has been designated for assignment. That’s the corresponding 40-man move for the signing of righty Jake Woodford, a move that was previously reported.
Nelson, now 28, has been with the Diamondbacks for years. He was claimed off waivers from the Guardians in the 2021-22 offseason. He showed some potential at times but required surgery to treat thoracic outlet syndrome in April of 2024 and his numbers since that procedure have been rough.
He missed the remainder of the 2024 campaign after going under the knife. Here in 2025, he has been on optional assignment, having tossed 17 Triple-A innings. He has allowed 16 earned runs in that time, leading to an 8.47 ERA. That’s a small sample of work but he also only has 12 strikeouts, a rate of 14.6% of batters faced. He has averaged just 89.9 miles per hour on his fastball.
There’s a big gap between that performance and what he was able to do a few years ago. In 2023, he logged 56 major league innings for the Snakes with a 4.18 ERA. He struck out 28% of batters faced while averaging 92 mph on his fastball.
Overcoming a thoracic outlet syndrome diagnosis is notoriously difficult. Pitchers like Matt Harvey and Chris Archer declined significantly later in their careers while Stephen Strasburg essentially had his career ended by the condition. On the other hand, Diamondbacks like Merrill Kelly and Ryan Thompson have each managed to engineer solid post-TOS seasons.
Nelson will now head into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Snakes could take five days to explore trade talks. Based on his injury absence and recent results, there may not be much interest.
If Nelson clears outright waivers, he will have the right to elect free agency but will probably decide to stay. Players with at least three years of big league service time have the right to reject an outright assignment, but those with less than five years have to forfeit their remaining salary in order to exercise that right. Nelson is in that three- to five-year window. He and the club avoided arbitration in the offseason by agreeing to a salary of $825K this year, a bit north of the $760K major league minimum.

Diamondbacks Reassign Trey Mancini To Minor League Camp
Opening Day is just a week away, which means the camp cuts will become more notable. The Diamondbacks made a few today. They optioned pitchers Kyle Nelson and Drey Jameson as well as infielder Jordan Lawlar to Triple-A Reno. Right-hander Scott McGough and first baseman/outfielder Trey Mancini, who were in camp as non-roster invitees, were reassigned to minor league camp.
Mancini’s reassignment is arguably the most notable move of the bunch. The veteran signed a minor league deal with the Snakes last month and put up huge numbers this spring. In 27 Cactus League plate appearances, he has a line of .440/.481/.640. An unsustainable .667 batting average on balls in play is helping him out, but it’s still a nice showing for a guy who didn’t play in 2024.
Longtime baseball fans will be familiar with Mancini’s inspirational journey. He hit 86 home runs and slashed .276/.335/.485 for the Orioles over the 2016 through 2019 seasons, production which translated to a 116 wRC+. He then missed the entire 2020 season while battling colon cancer. He made a triumphant return in 2021, hitting another 21 home runs and putting up a .255/.326/.432 line and 105 wRC+. He produced largely similar numbers in 2022, a season in which he was traded to the Astros and earned a World Series ring.
The two subsequent years were a challenge. He signed a two-year, $14MM deal with the Cubs going into 2023 but hit .234/.299/.336 for a 76 wRC+ and was released in early August. Going into 2024, he signed a minor league deal with the Marlins but opted out of that deal at the end of camp. He didn’t sign anywhere else during the 2024 season. It was reported in November that he was looking to mount a comeback bid, which was followed by a minor league deal with the Snakes in February.
What’s unclear now is if Mancini has an opt-out on this deal, as he did in his pact with the Marlins last spring. Some veterans get automatic opt-outs on minor league deals, but one of the requirements for those is that a player was on a major league roster or injured list at the end of the previous season. That was not the case for Mancini, so the only way he would have an opt-out is if he negotiated one into his contract.
After missing the entire 2024 season, perhaps he would welcome the opportunity to play in some minor league games and get back into a normal rhythm. However, given his track record and big spring numbers, he might also be interested in seeing what other opportunities are out there. The Snakes seem likely to use Josh Naylor and Pavin Smith as regulars in the first base and designated hitter spots. Mancini has experience in the outfield corners as well but has never graded out well there and the D’Backs have plenty of options for those spots.
Lawlar is perhaps the best-known name among the other players, since he has been one of the top prospects in baseball for a while. He made his big league debut late in 2023 but hit just .129/.206/.129 in 34 plate appearances. He then missed most of the 2024 season due to injury, getting into just 23 minor league games. He’s having a strong spring, hitting .294/.368/.529, but getting optioned is a sensible move.
Arizona has Geraldo Perdomo and Eugenio Suárez covering Lawlar’s primary positions of shortstop and third base. After a mostly lost season, getting regular reps in Reno is probably what’s best for him, especially since he’s still just 22 years old. Suárez is an impending free agent, so a solid campaign from Lawlar could line him up for a regular big league role next year. Or perhaps sooner, if injuries create an opening.
Jameson, 27, has some decent big league numbers. He tossed 65 innings for the Snakes over 2022 and 2023, making seven starts and 12 relief appearances. He missed the entire 2024 season recovering from Tommy John surgery. It’s unclear if the Diamondbacks view him more as a starter or reliever going forward. After missing all of last year, perhaps pitching in Triple-A is better either way.
If he is to continue starting, they don’t have a big league role for him now anyway. They have seven viable rotation options in Corbin Burnes, Zac Gallen, Merrill Kelly, Eduardo Rodríguez, Jordan Montgomery, Brandon Pfaadt and Ryne Nelson. However, Gallen, Kelly and Montgomery are impending free agents and Burnes can opt-out after 2026, so there are long-term jobs available if Jameson returns to starting in Reno this year.
Players Who Could Move To The 60-Day IL Once Spring Training Begins
Most of the clubs in the league currently have a full 40-man roster, which means that just about every transaction requires a corresponding move these days. Some extra roster flexibility is on the way, however. The 60-day injured list goes away five days after the World Series but comes back when pitchers and catchers report to spring training.
Per R.J. Anderson of CBS Sports, most clubs have a report date of February 12th or 13th. The Cubs and Dodgers are a bit earlier than most, on the 9th and 11th, respectively. That’s due to the fact that those clubs are heading to Tokyo, with exhibition games in mid-March, followed by regular season games against each other on March 18th and 19th. All the other teams have Opening Day scheduled for March 27th.
It’s worth pointing out that the 60 days don’t start being counted until Opening Day. Although a team can transfer a player to the 60-day IL quite soon, they will likely only do so if they aren’t expecting the player back until end of May or later. A team also must have a full 40-man roster in order to move a player to the 60-day IL.
There are still plenty of free agents still out there, including big names like Alex Bregman and Pete Alonso, as well as Nick Pivetta, Andrew Heaney, David Robertson, Randal Grichuk, Kenley Jansen, Harrison Bader, Lance Lynn, Jose Quintana and many more. Perhaps the extra roster flexibility will spur some deals to come together in the next week or so. It could also increase the ability of some clubs to make waiver claims or small trades for players who have been designated for assignment.
Here are some players who are expected to miss some significant time and could find themselves transferred soon.
Angels: Robert Stephenson
Stephenson underwent a hybrid Tommy John surgery with internal brace in late April. Given the 14-plus months required to recovery from such a procedure, he’s not likely to be ready in the early parts of the 2025 season.
Astros: Cristian Javier, J.P. France, Bennett Sousa
Javier underwent Tommy John surgery in June and is targeting a return in the second half of 2025. France is recovering from shoulder surgery and hoping to return in July. Sousa’s timeline is less clear but he underwent surgery for thoracic outlet syndrome in April. Other possibilities include Luis Garcia and Lance McCullers Jr., who are expected to start the season on the IL but returning in April or May still seems possible.
Athletics: Luis Medina, Ken Waldichuk
Medina underwent Tommy John surgery in August and Waldichuk in May. Medina might miss the entire season while Waldichuk is likely to miss a few months at least.
Blue Jays: Angel Bastardo, Alek Manoah
The Jays grabbed Bastardo from the Red Sox in the Rule 5 draft in December, even though he had Tommy John surgery in June. Manoah also had Tommy John around that time and is hoping to be back by August.
Braves: Joe Jiménez
Jimenez had knee surgery in November with a timeline of eight to twelve months, so he might miss the entire season. Spencer Strider and Ronald Acuña Jr. are also possibilities, though those will be more borderline. Strider had internal brace surgery in April, so returning in May is somewhat possible. Acuña is recovering from a torn ACL last year and it’s possible he’ll miss the first month or so of the season. Given how important both of those players are, Atlanta probably won’t put them on the 60-day IL unless it’s 100% certain that they can’t come back in the first 60 days of the season.
Brewers: Robert Gasser
Gasser had Tommy John surgery in June and will be looking at a late 2025 return even in a best-case scenario.
Diamondbacks: Kyle Nelson
Nelson’s timeline is unclear, but he underwent surgery for thoracic outlet syndrome in May and missed the remainder of the 2024 season.
Dodgers: Gavin Stone, Brusdar Graterol, River Ryan, Kyle Hurt, Emmet Sheehan
Stone underwent shoulder surgery in October that will cause him to miss the entire year. Graterol also underwent shoulder surgery and isn’t expected back until the second half of 2025. Each of Ryan, Hurt and Sheehan required Tommy John surgery in 2024: Ryan in August, Hurt in July and Sheehan in May.
Guardians: Sam Hentges, David Fry, Shane Bieber, Trevor Stephan
Hentges required shoulder surgery in September, with an expected recovery timeline of 12 to 14 months. Fry underwent UCL surgery in November with a more fluid timeline. He won’t be able to throw at all in 2025 but could be cleared for designated hitter action six to eight months from that surgery. Bieber is perhaps a borderline case, as he underwent Tommy John surgery in April. Given his importance, the Guards may not transfer him to the 60-day IL until it’s assured that he won’t be back in the first 60 days of the season. Stephan underwent Tommy John surgery in March and perhaps has a chance to avoid the 60-day IL, depending on his progression.
Mariners: Matt Brash, Jackson Kowar
Brash underwent Tommy John surgery in May. Given the typical 14-month recovery timeline from that procedure, he would be looking at a midsummer return. However, it was reported in November that he’s ahead of schedule and could be back by the end of April. That’s an optimistic timeline but the Mariners will probably hold off moving him to the 60-day IL until the door is closed to an early return. Kowar underwent Tommy John in March, so an early return in 2025 is possible for him, depending on how his recovery is going.
Marlins: Braxton Garrett, Eury Pérez
Garrett just underwent UCL surgery last month and is going to miss the entire 2025 season. Pérez underwent Tommy John surgery in April of last year and will miss at least part of the beginning of the 2025 campaign.
Mets: Christian Scott
Scott required a Tommy John surgery and internal brace hybrid procedure in September and will likely miss the entire 2025 season.
Nationals: Josiah Gray, Mason Thompson
Gray required a Tommy John surgery and internal brace hybrid procedure in July, meaning he’ll miss most or perhaps all of the 2025 season. Thompson required Tommy John surgery in March, so he has a better chance to make an early-season return if his recovery is going well.
Orioles: Kyle Bradish, Tyler Wells
Bradish and Wells each required UCL surgery in June, so they’re both slated to miss the first half of the upcoming campaign.
Padres: Joe Musgrove
Musgrove had Tommy John surgery in October and will therefore miss the entire 2025 season. However, the Padres only have 36 guys on their 40-man roster at the moment, so they’ll need to fill those spots before moving Musgrove to the 60-day IL.
Pirates: Dauri Moreta
Moreta required UCL surgery in March, so an early-season return is possible if his rehab is going well, though he could end up on the 60-day if the club goes easy with his ramp-up or he suffers any kind of setback.
Rangers: Josh Sborz
Sborz underwent shoulder surgery in November and is expected to miss the first two to three months of the upcoming season.
Rays: Nate Lavender, Ha-Seong Kim
The Rays took Lavender from the Mets in the Rule 5 draft, even though he had Tommy John in May and will miss the start of the season. Kim’s status is more up in the air after he had shoulder surgery in October. Various reports have suggested he could return anywhere from April to July. The Rays made a sizable investment in Kim, their largest ever for a position player, so they probably won’t shelve him until they get more clarity on his status.
Red Sox: Patrick Sandoval, Garrett Whitlock, Chris Murphy
Sandoval had internal brace surgery in June of last year and should miss the first half of the season. Whitlock had the same surgery in May, so he could have a bit of a better chance to return in the first 60 days of the season. Murphy underwent a fully Tommy John surgery in April and will certainly miss the beginning of the upcoming season. Another possibility is Lucas Giolito, who had internal brace surgery in March, though he expects to be ready by Opening Day.
Reds: Julian Aguiar, Brandon Williamson
Aguiar underwent Tommy John surgery in October and Williamson in September, so both are likely slated to miss the entire 2025 season.
Tigers: Sawyer Gipson-Long
Gipson-Long underwent internal brace surgery in April. On top of that, he underwent left hip labral repair surgery in July, with the club hoping to address both issues at the same time. It seems likely that he’ll miss some of the early 2025 schedule, but his IL placement will depend on how he’s been progressing.
White Sox: Jesse Scholtens
Scholtens underwent Tommy John surgery in early March. Whether he goes on the 60-day IL or not will depend on how he’s progressed since then and when the White Sox expect him back.
Yankees: Jonathan Loáisiga
Loáisiga underwent internal brace surgery in April, so he could potentially be back on the mound early in the 2025 season. It was reported in December that the Yankees are expecting him to be in the bullpen by late April or early May, so he’ll only end up on the 60-day IL if he suffers a bit of a setback.
D-Backs’ Kyle Nelson To Undergo Thoracic Outlet Surgery
Diamondbacks reliever Kyle Nelson will undergo surgery to treat thoracic outlet syndrome, manager Torey Lovullo told reporters (link via Alex Weiner of Arizona Sports). There’s no official timetable for Nelson’s return to game action, but the Snakes placed him on the 60-day injured list when they called up Brandon Hughes this afternoon.
The track record for players, especially pitchers, returning from thoracic outlet surgery is mixed. Players like Matt Harvey and Chris Archer never regained their pre-surgery form, while the condition essentially ended Stephen Strasburg’s career. On the other hand, Nelson’s teammate Merrill Kelly has perhaps had the best post-TOS career of anyone to undergo the procedure to date. Kelly recently suffered a shoulder injury but had been healthy and very effective between his 2020 surgery and this April. Nelson’s bullpen mate Ryan Thompson has also rebounded after undergoing a TOS procedure while he was a member of the Rays in 2021.
However Nelson’s long-term recovery plays out, his loss deals an immediate hit to the Arizona relief group. A waiver claim from the Guardians three years ago, he owns a 3.47 ERA in 114 innings with the Snakes. Nelson outperformed middling strikeout and walk numbers in 2022 before flipping the script a year ago.
While his ERA jumped nearly two runs between 2022 and ’23, Nelson dramatically increased his strikeout rate and sliced his walk percentage. He has made 11 appearances this year. He opened the season by rattling off eight consecutive scoreless outings before giving up a combined five runs in 1 2/3 frames over his last three games. Nelson will be eligible for arbitration for the first time next offseason.
Arizona has four left-handers in the current bullpen mix: Hughes, Andrew Saalfrank, Joe Mantiply and long man Logan Allen. Hughes and Allen were recent additions to the 40-man roster who might not hold long-term spots, while Saalfrank has spent most of the season in the minors. The Snakes recently snagged grounder specialist Joe Jacques off waivers from the Red Sox and optioned him to Triple-A Reno. Adding a more proven lefty relief arm could be a midseason goal if the D-Backs stick in the playoff mix.
