Kyle Nelson

D-Backs’ Kyle Nelson To Undergo Thoracic Outlet Surgery

By | at

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.

Diamondbacks Select Brandon Hughes

By | at

The Diamondbacks announced that they have selected the contract of left-hander Brandon Hughes. Fellow lefty Tommy Henry was optioned to Triple-A Reno to open an active roster spot. To get Hughes onto the 40-man, lefty Kyle Nelson was transferred to the 60-day injured list.

Hughes, now 28, had a solid debut with the Cubs in 2022. He tossed 57 2/3 innings that year with a 3.12 earned run average, striking out 28.5% of batters faced while giving out walks at an 8.8% clip. He even moved into a leverage role, securing eight saves and eight holds that year.

But he found some struggles last year, going on and off the injured list throughout the season due to left knee inflammation. He made just 17 appearances with a bloated 7.24 ERA before eventually requiring surgery in June. He underwent a debridement procedure on that left knee and wasn’t able to return to the big league club in the final months of the season.

The Cubs non-tendered Hughes at the end of last year and he landed with the Snakes on a minor league deal. He has been getting good results in Triple-A so far, with a 1.84 ERA through 14 2/3 innings for Reno. However, those results are in spite of subpar strikeout and walk rates of 20% and 15%, respectively.

This is the second time Henry has been optioned, as he has been helping the club cover for some rotation injuries, posting a 5.40 ERA in six starts. Him being optioned today leaves the Diamondbacks with a rotation of Zac Gallen, Brandon Pfaadt, Jordan Montgomery and Slade Cecconi, while Eduardo Rodríguez, Merrill Kelly and Ryne Nelson are on the injured list.

They will need a fifth starter but not right away. They have an off-day on Thursday and another on Monday, therefore allowing them to use just four starters until next weekend, if they so choose. Manager Torey Lovullo said that Ryne Nelson recently threw a sim game of five innings and 75 pitches, per Alex Weiner of AZSports. That perhaps suggests he’s not far off from a return to the club. But for now, Hughes will give Lovullo another bullpen lefty alongside Joe Mantiply, Andrew Saalfrank and Logan Allen.

As for the other Nelson, Kyle was placed on the 15-day injured list a week ago due to left shoulder inflammation. It’s unclear how long the club expects him to be out of action but this transfer means he’s ineligible to be reinstated until mid-June.

Diamondbacks Select Wilmer Difo, Designate Noe Ramirez

By | at

The Diamondbacks announced they’ve selected infielder Wilmer Difo onto the big league roster. They’ve also reinstated relievers Keynan Middleton and Kyle Nelson from the 15-day injured list. To create space on the active and 40-man rosters, Arizona designated right-hander Noé Ramirez for assignment.

Difo gets his first MLB crack of the year, reaching the big leagues for what’ll be an eighth straight season. A switch-hitting middle infielder, Difo has decent contact skills but doesn’t offer much in the way of power production. He’s a .251/.313/.355 hitter in exactly 1300 MLB plate appearances split between the Nationals and Pirates, with the vast majority of that time coming in Washington. Difo has ample experience all throughout the infield, and he’s generally rated well in the eyes of public defensive metrics as a shortstop.

It’s been a similar story in Triple-A Reno this year. The 30-year-old has logged plenty of action at shortstop and third base, and he’s compiled a .269/.311/.398 line over 306 trips to the plate. Difo has struck out in just 13.4% of his plate appearances, but his lack of extra-base impact has been glaring in one of the more hitter-friendly environments in affiliated ball. He’ll nevertheless get a look on the strength of his glove, offering manager Torey Lovullo a defensive specialist off the bench for the stretch run. Difo will be arbitration-eligible this winter and could be kept around for next season, although he’s a likelier non-tender candidate given his journeyman status and below-average offensive showing in Triple-A.

Nelson and Middleton have each missed over a month dealing with injuries: back spasms for Nelson, an ankle strain for Middleton. The former has made 38 appearances during his first season in the desert, working to a sparkling 1.57 ERA in 34 1/3 innings but only striking out 20.5% of opponents. The latter has only pitched 12 times, pitching to a 1.64 ERA with a 25% strikeout rate in 11 frames.

With Nelson and Middleton returning to the bullpen, the D-Backs had to cut one of their incumbent pitchers. (Teams must devote one of the two extra roster spots in September to a position player). The veteran Ramirez finds himself as the odd man out after posting a lackluster 5.22 ERA through 50 innings. Ramirez has punched out 23.7% of batters faced on a solid 11.8% swinging strike percentage, but he’s also walked batters at an alarming 12.1% clip.

The 32-year-old Ramirez spent most of last season in Arizona as well. He signed a minor league deal after being released by the Angels and made the big league roster in June. Ramirez impressed enough down the stretch the D-Backs agreed to bring him back on a $1.25MM salary. They weren’t prepared to do so again this winter, and they’ll now place him on waivers in the next couple days.

If no other team wants to assume the remaining $240K on his contract, Ramirez is likely to head to the open market. He has more than five years of major league service time, giving him the right to refuse an outright assignment in favor of free agency while still collecting the remainder of his guaranteed salary.

Diamondbacks Transfer Luke Weaver To 60-Day Injured List, Reinstate Kyle Nelson, Option Tyler Holton

By | at

The Diamondbacks made a number of roster moves today. They reinstated southpaw Kyle Nelson from the injured list, optioned Tyler Holton to Triple-A, and transferred Luke Weaver to the 60-day injured list, per the team.

Weaver faced just five batters this year before hitting yet another injury roadblock. He worked through blister issues in the spring, returning to find a spot on the active roster. But after just two thirds of an inning in relief, he was placed on the 10-day injured list with right elbow inflammation. At this stage, the change in designation means Weaver won’t be able to return before June 7, though his long-term outlook remains unclear at this point.

Nelson, meanwhile, returns from the COVID injured list. The 25-year-old has a 1.23 ERA/1.57 FIP in 15 appearances covering 14 2/3 innings so far this season. Nelson was selected off waivers from the Guardians this past November. The former 15th-round pick had made just 11 career appearances for the Guardians without much success, yielding 14 earned runs in just 10 1/3 innings. Needless to say, Nelson is off to a better start in Arizona.

As for Holton, the 25-year-old southpaw made two appearances, tossing three scoreless innings for the Snakes. He’ll head back to Triple-A for now, where he owns a 5.65 ERA over 14 1/3 innings of work.

Diamondbacks Place Kyle Nelson, Cooper Hummel On Injured List

By | at

The Diamondbacks announced a series of roster moves, including the placement of left-hander Kyle Nelson and outfielder Cooper Hummel on the injured list.  No designation was specified, which indicates that the placements are related to COVID-19.  With right-hander Edwin Uceta also optioned to Triple-A after yesterday’s game, the D’Backs will fill the three roster vacancies with infielder Yonny Hernandez and right-handers Luis Frias and Jacob Webb.  Frias was called up from Triple-A, while Hernandez and Webb were recalled from the taxi squad.

Nelson has been one of the most effective members of Arizona’s bullpen, posting a 1.23 ERA, 30.2% strikeout rate, and a 3.8% walk rate over his first 14 2/3 innings of the season.  After struggling at both the Triple-A level and in 10 1/3 big league innings with Cleveland in 2019-20, Nelson’s early-season performance could indicate that he has harnessed the big strikeout potential he showed throughout his minor league career.  The Diamondbacks claimed Nelson off waivers from the Guardians back in November.

Hummel is in his rookie season, with a .190/.313/.345 slash line (92 wRC+ and OPS+) to show for his first 99 plate appearances as a big leaguer.  The switch-hitter has seen a lot of DH and pinch-hitting duty, and Hummel has also received some starts in left field when a left-hander is on the mound (thus relegating David Peralta to the bench).  Hernandez is also a switch-hitter, though Jordan Luplow figures to more directly take over Hummel’s role while Hummel is sidelined.

As always with the COVID list, it is possible Nelson or Hummel could be activated as early as tomorrow, if their placement was only due to a close-contact situation or symptoms without a positive test.  If either has tested positive, Nelson/Hummel will miss a minimum of 10 days, unless they meet the criteria (two negative tests, clearance from three physicians, 24 hours without a fever) for early activation.

Diamondbacks Place Luke Weaver On 10-Day IL

By | at

The Diamondbacks announced that right-hander Luke Weaver has been placed on the 10-day injured list due to right elbow inflammation.  The placement is retroactive to April 8.  Left-hander Kyle Nelson has been called up from Triple-A to take Weaver’s spot on the active roster.  In other moves, the D’Backs outrighted southpaw Caleb Baragar and righty Humberto Mejia to Triple-A, as both of the recently-designated pitchers cleared waivers.

Weaver tossed two-thirds of an inning of relief work in Thursday’s 4-2 Arizona win over the Padres, allowing a run on three hits.  An elbow issue could be the reason behind that shaky outing, though Weaver was also dealing with a blister problem during the end of Spring Training.  Weaver worked exclusively as a starter in 2019-21, but the D’Backs are using him as a reliever in the early going of the season, so this IL stint could delay any eventual return to the rotation.

Nelson will now step into Arizona’s bullpen, and the southpaw’s first appearance will mark his Diamondbacks debut.  Nelson has pitched in each of the last two seasons, with only a 12.19 ERA to show for 10 1/3 innings in The Show.  The D’Backs claimed Nelson off waivers from the Guardians in November, after Nelson had spent all five of his professional seasons in Cleveland’s organization.

Diamondbacks Claim Kyle Nelson From Guardians

By | at

The Diamondbacks have claimed reliever Kyle Nelson off waivers from the Guardians, per announcements from both teams. Cleveland also announced that outfielder Daniel Johnson, right-hander Justin Garza and left-hander Alex Young have all cleared waivers and been sent outright to Triple-A Columbus. Arizona’s 40-man roster is now full.

Nelson has briefly appeared in the majors in each of the past two seasons. He’s tallied just 10 1/3 combined innings, allowing fourteen runs with nine walks and eight strikeouts. The southpaw has struggled to a 5.26 ERA in 37 2/3 career frames at the Triple-A level as well, but he’d kept runs off the board and punched out batters in droves up through Double-A.

During his limited MLB time, Nelson leaned primarily on a cutter and slider mix. He averaged just under 89 MPH on the cutter and worked in the low-80s with his slider, relying more on movement than velocity. The D-Backs have almost no certainty in the bullpen, as they’re not returning a single reliever who tossed 20+ innings with a SIERA below 4.00 this past season. There should be an opportunity for Nelson to compete for a role in Spring Training, if he sticks on the 40-man roster all winter. He still has a pair of minor league option years remaining, so the D-Backs could shuttle him between Phoenix and Triple-A Reno through 2023 as long as he remains on the 40-man.

Each of Johnson, Garza and Young was designated for assignment last Friday, as Cleveland somewhat remarkably overturned around one quarter of their 40-man roster before the deadline to keep prospects from being eligible for the Rule 5 draft. The Guardians also traded Harold Ramírez and J.C. Mejia (to the Cubs and Brewers, respectively), while losing Scott Moss on waivers to the Phillies.

Johnson has been a fairly well-regarded prospect during his days in the Nationals and Cleveland farm systems, but he hasn’t hit well over his first 94 big league plate appearances. He’ll remain in the organization as non-roster depth and hope to play his way back into an uncertain Guardians’ outfield mix next spring.

Garza and Young logged some big league time in the bullpen this past season, with Young coming over from the D-Backs as a waiver claim in July. Garza pitched to a 4.71 ERA/4.79 SIERA across 28 2/3 innings; Young worked 10 1/3 innings of 7.84 ERA/6.24 SIERA ball with Cleveland. Both hurlers have ample starting experience during their pro careers as well.

Guardians Designate Seven Players For Assignment

By and | at

The Guardians announced Friday that they’ve designated outfielders Daniel Johnson and Harold Ramirez; righties Justin Garza and J.C. Mejia; and lefties Kyle Nelson, Alex Young and Scott Moss for assignment.

Cleveland also added a whopping 10 players to the 40-man roster, headlined by top prospects Tyler Freeman and George Valera. Also added to the 40-man roster are Brayan Rocchio, Richie Palacios, Steven Kwan, Jose Tena, Cody Morris, Bryan Lavastida, Konnor Pilkington and Jhonkensy Noel.

Finally, the Guardians have also acquired right-hander Tobias Myers from the Rays in exchange for minor league infielder Junior Caminero, tweets FanGraphs’ Eric Longenhagen. Myers will also be added to the 40-man roster.

Johnson and Ramirez have been part of a revolving door in an uncertain Cleveland outfield in recent seasons. Neither has hit well enough to lock down a permanent roster spot, although Ramirez did start more than half the team’s games in 2021. Ramirez would have the right to elect minor league free agency if he clears waivers.

Mejia logged significant action as a depth starter this year but struggled. Garza, Nelson and Young saw some bullpen work, while Moss has yet to make it to the major leagues.

The massive turnover highlights the high minors depth Cleveland has stockpiled in recent seasons. The selection of ten prospects is highly atypical, but it’s a testament to the Guardians’ scouting and development staffs that they’ve managed to accumulate so much talent they’re afraid other teams might jump on. That’s particularly true on the position player side, with much of this group being hitters with advanced bat-to-ball skills who could factor onto the big league roster in relatively short order.

Freeman, Valera and Rocchio might be the most notable. All three appeared on FanGraphs’ Top 100 list entering the 2021 season. They’ve all topped out at Double-A Akron, where each posted above-average offensive performances despite being 22 years old or younger. Valera plays center field, while Freeman and Rocchio are middle infielders. Palacios is another infielder with great high minors numbers, while Lavastida is regarded as one of the better catching prospects in the minors.

Indians Option Triston McKenzie To Triple-A

By | at

The Indians sent right-hander Triston McKenzie to Triple-A Columbus, as originally noted on MLB.com’s transactions page and confirmed by multiple reporters.  Right-hander Kyle Nelson was called up to take the open spot on the active roster.

Selected 42nd overall in the 2015 draft, McKenzie has been a fixture on top-100 prospect list for the last few years, even though forearm and shoulder injuries sidelined him for all of the 2019 season.  As a result, this will be McKenzie’s first appearance in Triple-A baseball, after pitching 90 2/3 innings at the Double-A level in 2018.

The Tribe saw enough in McKenzie at their alternate training site last season to promote him to the big leagues without the benefit of any Triple-A time, and McKenzie made an immediate impression.  He posted a 3.24 ERA and a strong 33.1% strikeout rate in his first 33 1/3 career innings, and it seemed like he was on his way to becoming Cleveland’s latest homegrown pitching star.

While McKenzie’s future is still bright, the 2021 season has been a speed bump.  McKenzie has a 6.89 ERA over 31 1/3 innings, still with a big strikeout rate (30.6%) but not much else positive within his metrics.  The 23-year-old has among the worst hard-contact numbers of any pitcher in baseball, and his garish 20.8% walk rate is the highest of any hurler in baseball with at least 30 innings pitched.

The extreme control problems are unusual, since McKenzie had very solid and even above-average walk rate during his minor league career.  It’s possible the numbers could just be an aberration, though the Tribe will let him work things out at Triple-A rather than risk more struggles at the big league level.

For taking over McKenzie’s rotation spot, Logan Allen might be the easiest choice to fill in, though he has also struggled over five starts with the Tribe this season.  Jean Carlos Mejia or Cal Quantrill could be stretched out as starters, or Eli Morgan or Scott Moss might be options at Triple-A.

Indians Announce Roster Decisions

By | at

The Indians have informed first baseman Jake Bauers, lefty Oliver Perez, infielder Yu Chang and outfielder Ben Gamel that they’ve made the Opening Day roster, the club announced to reporters (Twitter links via Ryan Lewis of the Akron Beacon-Journal). First base prospect Bobby Bradley, outfielder Bradley Zimmer, veteran righty Blake Parker and young lefty Kyle Nelson have all been told they will not head north with the club.

The slate of decisions means that Bauers, who is out of minor league options, will get one more opportunity to fend off Bradley. Bauers didn’t show particularly well this spring, slashing just .200/.429/.280 in 35 trips to the plate. Bradley’s .303/.314/.636 output trounced that, but we’re looking at small samples of data and it’s common this time of year for clubs to be averse to losing out-of-options players on waivers.

Bauers is still just 25 years old and is a former top prospect himself, although he didn’t play in the big leagues last year and carries a rather marginal .214/.314/.377 slash in 811 career plate appearances. Bradley, 24, got an opportunity in the big leagues last season but stumbled with a .178/.245/.356 line in 49 trips to the plate.

With the Indians optioning both Zimmer and Oscar Mercado to Triple-A this week, it appears that Gamel, who’d been in camp as a non-roster invitee, will be one of their primary options in center field. He could split time with Amed Rosario there, although Cleveland’s experiments with him in the outfield thus far in Spring Training have been somewhat adventurous. Gamel has more experience there and seems likely to see plenty of opportunity despite a tepid .212/.316/.364 showing in 38 spring plate appearances.

Chang’s case for a roster spot improved earlier in camp when veteran Mike Freeman was traded over to the Reds. The 25-year-old Chang hasn’t hit much in parts of two seasons with the Indians in 2019-20, but he’s also received just 97 plate appearances in the Majors. Perez, meanwhile, has spent the past three seasons in Cleveland’s bullpen and thrown quite well, so it comes as little surprise that they’ll bring him back for a fourth year. Parker came to camp with a decent chance to grab a spot but has been clobbered for a dozen runs in 6 1/3 innings. His track record in the big leagues is obviously quite a bit better than that disastrous showing, but it’s not hard to see why Cleveland went in another direction after that audition.

Though the team has announced its decisions, the moves themselves aren’t yet formal. Both Perez and Gamel were in camp on non-roster deals, as was veteran righty Bryan Shaw, who made the club earlier in the week. All three will need to be added to the 40-man roster between now and Opening Day, so the Indians clearly have some roster tweaking on the horizon.
