Lewin Diaz

Marlins Select Sean Guenther, Option Lewin Diaz

By | at

The Marlins have selected the contract of left-hander Sean Guenther from Triple-A Jacksonville.  First baseman Lewin Diaz was optioned to Triple-A in the corresponding move.

The 25-year-old Guenther is now in position to make his Major League debut.  A seventh-round pick out of Notre Dame in the 2017 draft, Guenther isn’t ranked by either Baseball America or MLB Pipeline as one of Miami’s top 30 prospects, but the lefty has earned his promotion with some strong numbers.  Since becoming a full-time relief pitcher in 2019, Guenther has greatly increased his strikeout totals, with a 34% K rate over 40 1/3 combined innings at Double-A and Triple-A ball this season.

2021 marked the first time Guenther had pitched beyond the A-ball level, and while he performed well at Double-A, his 4.76 ERA over 22 2/3 Triple-A frames indicates some growing pains.  Still, much of that damage was done over two calamitous  outings on July 6 and 9, as Guenther allowed nine runs over 1 2/3 total innings.

While Guenther will get his first taste of the majors, Diaz heads back to Triple-A after another brief stint with the Marlins.  Diaz has only a .496 OPS over 73 career plate appearances with Miami, but the 24-year-old has already displayed a lot of power potential down on the farm, albeit without much plate discipline.

Marlins Designate Luis Madero For Assignment

By | at

The Marlins have designated righty Luis Madero for assignment, as The Miami Herald’s David Wilson was among to report.  First baseman Lewin Diaz has been called up from Triple-A in the corresponding move.

This is already the third time Miami has DFA’ed Madero since the start of May, though amidst the roster maneuvering, the right-hander did make his Major League debut.  Madero has tossed four innings over three games for the Marlins, with one disastrous outing (five runs in one inning against the Diamondbacks on May 11) accounting for his 11.25 ERA.

Beginning his career as a 17-year-old in Arizona’s farm system in 2014, Madero pitched for the D’Backs, Angels, and was briefly in the Giants organization before joining the Marlins on a minor league deal last winter.  Starting 92 of his 110 career games in the minors, Madero has a 4.34 ERA and 20.73% strikeout rate over an even 500 minor league innings.

Marlins Reinstate Starling Marte From Injured List

By | at

The Marlins announced a series of roster moves this afternoon (via Jordan McPherson of the Miami Herald). Center fielder Starling Marté has been activated from the injured list, while infielder Luis Marté has been selected to the roster. To clear active roster space, first baseman Lewin Díaz was optioned to Triple-A Jacksonville, while shortstop Miguel Rojas was placed on the 10-day injured list with a dislocated left index finger. Miami already had an open spot on the 40-man roster, so no additional move was required to accommodate Luis Marté’s selection.

Starling Marté got off to a good start to the season, hitting .310/.414/.483 with a pair of homers over his first 70 plate appearances. That was halted when Marté suffered a non-displaced rib fracture on a swing in mid-April, sending him to the IL. He’ll now return to action a little less than six weeks later, where he’ll try to build on his solid work early in the year.

It’s an important season for Marté, who’s in the final year of the contract extension he signed with the Pirates in March 2014. The 32-year-old is a few months away from his first trip to the open market. Marté’s strong track record and expiring contract would also make him a plausible midseason trade candidate if Miami falls out of the National League postseason picture. The young Marlins have held around in a jam-packed NL East, going 24-26 over their first 50 games. Despite that, FanGraphs pegs the team’s playoff odds at a meager 1.5%, so it wouldn’t be a surprise to see Marté’s name floated in trade talks in the coming months.

Rojas suffered a “concerning” finger dislocation during yesterday’s game against the Phillies. It’s unclear how much time he’s expected to miss. The injury opened a spot for Luis Marté, who’ll be making his MLB debut the first time he gets into a game. The 27-year-old spent the first seven-plus seasons of his professional career in the Rangers system, topping out at Triple-A.

Marté was in the high minors with the Braves between 2018-19 and inked a minors deal with Miami over the winter. He’s never offered much at the plate, hitting .245/.263/.355 in four seasons at Double-A and .261/.284/.352 in nearly as much Triple-A time. Marté has ample experience all around the infield in the minors, though, and he’s hit three homers in 61 plate appearances this year with Jacksonville, albeit with similar on-base issues as he’s had throughout his career.

Marlins Announce Series Of Roster Moves

By | at

The Marlins announced a series of roster moves Tuesday, including the contract selections of right-hander Brett Eibner and lefty Brandon Leibrandt. They also optioned righties Jordan Yamamoto and Justin Shafer and infielder Lewin Diaz to their alternate training site; moved righty Mike Morin to the 45-day injured list; placed lefty Brian Moran on the 10-day IL with right knee patella tendonitis; recalled righty Humberto Mejia from their training site; and reinstated outfielder Corey Dickerson from the paternity list.

Eibner, a former Royals and Dodgers outfielder, last appeared in the majors in 2017. He switched to a two-way role thereafter and performed well enough as a pitcher in independent ball for the Marlins to recently purchase his contract from the Eastern Reyes del Tigre of the Constellation Energy League.

Leibrandt also isn’t far removed from joining the Marlins, who inked the ex-Phillies farmhand to a minors pact earlier this month. Most recently a member of the independent Somerset Patriots, the 27-year-old has never pitched in the bigs. He did enjoy a productive season in Triple-A ball in 2018, though, before succumbing to Tommy John surgery.

Marlins Designate Wei-Yin Chen, Add Six To 40-Man Roster

By | at

The Marlins announced Wednesday that they’ve designated left-hander Wei-Yin Chen for assignment and added six players to their MLB roster: shortstop Jazz Chisholm, first baseman Lewin Diaz and right-handers Sixto Sanchez, Nick Neidert, Humberto Mejia and Edward Cabrera. Miami owes Chen $22MM in 2020 — the final season of a five-year, $80MM free-agent contract.

Chen, now 34, was a steady source of quality innings from 2012-15 in Baltimore, pitching to a 3.72 ERA in the hitter-friendly AL East while averaging 29.25 starts and 176 innings per year. That durability and reliability led the Marlins to invest a whopping five-year, $80MM contract in the lefty when he hit the free-agent market, but the deal went south almost immediately. Chen barely kept his ERA under 5.00 and tossed just 123 1/3 innings in his first year with the Marlins. A UCL injury wiped out nearly all of his 2017 season and much of the 2018 campaign, and he pitched just 68 1/3 innings of ineffective relief work in 2019. Overall, he recorded a dismal 5.10 ERA in 358 innings with Miami.

Of the prospects protected tonight were acquired via the trade market, Chisholm (Zac Gallen), Diaz (Sergio Romo), Sanchez (J.T. Realmuto) and Neidert (Dee Gordon) were all acquired on the trade market under the team’s current ongoing rebuild. Sanchez is considered to be among the game’s premier pitching prospects, while Chisholm has drawn top 100 billing as well despite a rough showing at Double-A in 2019. Diaz was acquired from the Twins amid a huge rebound campaign. Neidert had an injury shortened ’19 season but profiles as a back-end starter. Cabrera reached Double-A as a 21-year-old this past season, while the 22-year-old Mejia turned in similarly impressive numbers and topped out in Class-A Advanced.

Players Added To 40-Man Roster: National League

By | at

We’re going to see a whole lot of players added to 40-man rosters in advance of tonight’s deadline to protect players from the Rule 5 draft. We will use this post to track those contract selections from National League teams that are not otherwise covered on the site.

NL West

  • The Dodgers announced that they’ve selected the contracts of right-hander Mitchell White, infielder/outfielder Zach McKinstry and outfielder DJ Peters. Both White and Peters are considered to be among the club’s top 15 prospects. McKinstry isn’t generally ranked inside L.A.’s top 30, but the 24-year-old had a big season between Double-A and Triple-A in 2019 while appearing at six defensive positions (shortstop, second base, third base and all three outfield slots).
  • The Diamondbacks announced that they’ve selected the contracts of right-handers Taylor Widener and Riley Smith as well as the contracts of infielders Andy Young and Wyatt Mathisen. Widener, 24, was one of the organization’s best pitching prospects coming into the season but was blown up for an eye-popping 8.10 ERA in 100 innings. He’s only a year removed from 137 1/3 innings of 2.75 ERA ball and an 11.5 K/9 mark in Double-A, however. Smith, 24, was sharp in Double-A before struggling in Triple-A — like many pitching prospects throughout the league (and with the D-backs in particular). Young, acquired in the Paul Goldschmidt trade last winter, hit 29 homers while playing three infield positions between Double-A and Triple-A. Mathisen, 26 in December, hit .283/.403/.601 in 345 Triple-A plate appearances.
  • The Giants, surprisingly, did not add anyone to their 40-man roster prior to tonight’s deadline.
  • The Rockies selected the contracts of infielder Tyler Nevin, left-hander Ben Bowden and right-handers Ashton Goudeau and Antonio Santos (Patrick Saunders of the Denver Post first reported the news on Twitter). Those four moves will fill the team’s 40-man roster. Of the four, Bowden and Nevin draw the most fanfare. Nevin, the No. 38 pick in the 2015 draft and son of former MLB slugger Phil Nevin, posted deceptively solid numbers in an extremely pitcher-friendly Double-A environment in 2019 (.251/.345/.399 — good for a 122 wRC+). Bowden, a second-round pick in ’16, posted gaudy strikeout numbers but struggled in Triple-A after dominating in Double-A in 2019.
  • The Padres selected outfielder Jorge Ona’s contract and designated outfielder Nick Martini for assignment, as outlined here.

NL Central

  • The Cardinals announced the additions of Jake Woodford, Elehuris Montero and Alvaro Seijas while designating righty Dominic Leone for assignment (as detailed here at greater length).
  • Outfielder Corey Ray and right-hander J.P. Feyereisen will head onto the Brewers 40-man, per Tom Haudricourt of the Milwaukee Journal-Sentinel (via Twitter). It’s not yet known if the team will make further roster additions, but it would have five additional spots to work with to do so. Ray was the fifth overall pick in the 2016 draft but is coming off of a rough season. Feyereisen, who was added in a quiet September swap, will have a chance to challenge for MLB relief opportunities. Milwaukee also added infielder Mark Mathias to the 40-man roster after acquiring him in a trade with the Indians tonight.
  • The Cubs announced that they’ve added catcher Miguel Amaya, infielder Zack Short and right-handers Tyson Miller and Manuel Rodriguez to the 40-man roster. Amaya is the most highly regarded of the bunch, ranking second among Chicago farmhands and drawing some top 100 consideration at MLB.com.
  • Four additions to the 40-man were announced by the Reds, who have selected the contracts of catcher Tyler Stephenson and right-handers Tony Santillan, Ryan Hendrix and Tejay Antone. All four rank within the club’s top 30 at MLB.com, headlined by Santillan at No. 4 and ranging all the way to Antone at No. 30. Santillan thrived in a brief Double-A debut in 2018 but struggled there in a larger 2019 sample (4.84 ERA, 8.1 K/9, 4.8 BB/9 in 102 1/3 innings). He’s still just 22, though, and is regarded as a potential big league starter. Stephenson is a former first-round pick who hit well in a highly pitcher-friendly Double-A setting (.285/.372/.410; 130 wRC+). Hendrix posted big strikeout numbers as a reliever in 2019, while Antone displayed sharp ground-ball skills as a starter and reached Triple-A for the first time.
  • The Pirates added prospects Ke’Bryan Hayes, Oneil Cruz, Will Craig, Blake Cederlind and Cody Ponce to the 40-man roster while also designating four pitchers for assignment (as explored in greater length here). Lefty Williams Jerez and right-handers Dario Agrazal, Montana DuRapau and Luis Escobar were cut loose.

NL East

Twins Sign Lewin Diaz, Roni Tapia

By | at

7:33pm: The Twins have also signed Dominican third baseman Roni Tapia for a $550K bonus, Wolfson tweets. Ben Badler of Baseball America writes that Tapia generates "easy power" but added that a position change is all but inevitable.

5:01pm: The Twins have signed Dominican outfielder Lewin Diaz, according to Darren Wolfson of 1500 ESPN (on Twitter). Diaz ranked as MLB.com's No. 10 international prospect in this year's class and was 15th on Baseball America's Top 30. According to MLB.com's Jesse Sanchez (on Twitter), Diaz signed for $1.4MM — a significant chunk of the Twins' $3.9MM bonus pool.

The 16-year-old Diaz's frame reminds some scouts of Ryan Howard, and MLB.com praises his power and approach: "Overall, Diaz has notable raw power and one of the best rhythm and timing approaches among all hitters in the international market this year."

Wolfson also adds that the Twins like Cuban defector Dariel Alvarez, but he will likely be too expensive. Signing Alvarez wouldn't count against Minnesota's bonus pool, because he's over 23 years of age and has more than three years of experience. There is no restriction on how much teams could spent to sign him. It was reported last week that Alvarez is eligible to sign with any team as a free agent.

July 2 Notes: Rankings, Twins, Trading Bonus Money

By | at

We're a day away from the kickoff of this year's international free agency period. Starting tomorrow, teams will be able to sign amateur free agents, many of whom will be just 16 years of age. Baseball America's Ben Badler reported each team's bonus pool back in April. The Astros ($4.93MM) have the most to spend while the Nationals ($1.85MM) have the least. Here's more on what to expect in this year's signing period…

  • Badler provides his list of Top 30 international prospects to the public for free, though subscribers can access full scouting reports on each of his Top 30. Dominican outfielder Eloy Jimenez tops Badler's list.
  • Jimenez also heads the Top 30 list compiled by MLB.com's Jonathan Mayo, though the two sets of rankings are quite different otherwise. For example, Mayo's No. 4 prospect — Dominican outfielder Wasner Peguero – does not appear on Badler's list at all.
  • Mayo's colleague at MLB.com, Jesse Sanchez, provides an in-depth profile of Jimenez. The 16-year-old tells Sanchez that he wants to be like his idol, Roberto Clemente. Sanchez writes that scouts praise Jimenez's speed, gap-to-gap power (which is expected to grow), quick hands and baseball intelligence. He's expected to end up in a corner outfield position. Jimenez tells Sanchez that July 2 is a day on which "dreams come true."
  • Sanchez also notes (Twitter link) that there's more to signing international free agents than just money. One current top prospect is deciding between two teams based on their GMs and how they have treated past international signees.
  • The Twins are expected to sign Dominican outfielder Lewin Diaz, writes LaVelle E. Neal of the Minneapolis Star Tribune. Minnesota is also very interested in Dominican right-hander Mayky Perez. They have interest in Italian infielder Marten Gasparini, but aren't likely to bid as highly as some other teams might. The Twins, for what it's worth, are the current record holders for largest bonus ever given to a European amateur. German outfielder Max Kepler received an $800K signing bonus in 2009.
  • In a subscription-only piece, Badler explains that general managers are having a hard time valuing bonus money in trades. The new CBA allows teams to exchange money from their international bonus pools, but the difficulty in trade talks is creating dilemmas for teams who have already given players or agents the impression that they will be able to commit a certain amount of money on July 2. Once a team uses all of its spending pool, it cannot trade for additional funds; trades must be completed prior to the exhaustion of a team's pool.
