Matt Koch

Minor League Moves: Hartlieb, Koch, Motter

By | at

The Marlins added pitcher Geoff Hartlieb to a minor league deal, per Baseball America’s minor league transactions page. Harltlieb, 29 next week, pitched for Boston’s Triple-A affiliate in 2022, tossing 61 innings of 5.16 ERA ball. He appeared in the big leagues for the Pirates and briefly the Mets, throwing 66 1/3 innings across three seasons with a 7.46 ERA. He had a slightly below average 20.5% strikeout rate against a 14.4% walk rate.

Here’s some other minor league signings from around the sport:

  • Matt Koch has landed a deal with the Rockies for 2023. The 32-year-old pitched a handful of innings for the Mariners in 2022, but spent most of the year at Triple-A, tossing 38 1/3 innings of 3.05 ERA ball. He spent four seasons in Arizona, throwing 129 2/3 innings of 5.00 ERA ball across 16 starts and 20 relief appearances. He doesn’t walk many batters, but doesn’t strikeout many either, averaging just five per nine innings across his big league career.
  • The Braves re-signed Brooks Wilson and Alan Rangel to minor league deals. Wilson, 26, largely worked as a reliever at Double-A, tossing 44 innings with a 2.45 ERA while striking out 14.9 batters per nine innings. He made a handful of appearances at Triple-A, and should start the year there in 2023. Rangel, 25, made 26 starts at Double-A, working to a 5.81 ERA across 114 2/3 innings.
  • The White Sox brought back 30-year-old outfielder Mark Payton. He appeared in just eight games in the big leagues this year, tallying three hits in 25 plate appearances. He had a strong season at Triple-A, hitting .293/.369/.539 with 25 home runs. He’s yet to translate that to the majors though, and has a lifetime .164/.261/.180 line in 40 games for the Reds and White Sox since his 2020 debut.
  • Daniel Duarte re-signed with the Reds for 2023. Celebrating his 26th birthday tomorrow, Duarte spent most of the season on the injured list, but appeared in three games for the Reds in 2022, giving up three runs in 2 2/3 innings. At Triple-A, he worked to a 9.39 ERA across 7 2/3 innings.
  • The Athletics added right-handed pitcher Jasseel De La Cruz to a minor league pact. The 25-year-old was signed out of the Dominican Republic by the Braves, and came up through their system as a solid pitching prospect. He struggled with injury in 2022, tossing just 26 1/3 innings in total, with 12 1/3 of those coming at Triple-A. There, he had an 8.03 ERA across seven appearances.
  • The Padres brought back Mexican pitcher Efrain Contreras on a minor league deal. The 22-year-old made 17 starts at High-A in 2022, working to a 5.74 ERA across 53 1/3 innings. While those numbers don’t look promising, he has averaged 10.2 strikeouts and 2.8 walks per nine innings across three seasons in the minor leagues.
  • Utilityman Taylor Motter has joined the Cardinals for the upcoming season. Motter, 32, has appeared in the big leagues for six different teams since 2016, hitting a combined .191/.262/.309 with ten home runs. He’s appeared at every defensive position outside of catcher and center field, but primarily handles the middle-infield spots. He made a handful of appearances for the Reds in 2022, but spent most of the year at Triple-A where he slashed .254/.357/.523 with 20 home runs for the Reds’ and Braves’ affiliates.
  • Puerto Rican shortstop Shawn Ross and the Pirates agreed to a minor league contract for the 2023 season. Ross, 22, played for Grand Junction in Independent ball in 2022, hitting 280/.408/.614 with 24 home runs.

19 Players Elect Free Agency

By | at

Players hit minor league free agency on a daily basis during the postseason, as opposed to major league free agents who hit free agency following the World Series when their contracts expire. On Thursday, MLBTR covered 15 players who elected minor league free agency, and we will continue to provide occasional updates as players continue to hit the open market, as noted on the MiLB.com transactions log.

If a player is not on their organization’s 40-man roster at the end of the season, he will hit minor league free agency as long as he has at least 3 years of MLB service time, been assigned outright more than once in his career, and/or has played in the minor leagues for parts of seven or more seasons. Everyone on today’s list is part of that group of players, and most will search for another minor league deal this offseason, though a few may manage to latch onto a major league club and secure a bench or bullpen spot entering the 2023 season.

Mariners Make Six Roster Moves

By | at

5:29PM: Brash will pitch out of the bullpen at Triple-A, as reported by The Seattle Times’ Ryan Divish and other media members.  Relief work could give Brash a quicker path back to the majors and allow him to better help the Mariners in 2022, even if the team still sees him as a longer-term starting pitcher.

2:47PM: The Mariners announced six roster moves, including the news that right-hander Matt Brash has been optioned to Triple-A.  Left-hander Nick Margevicius was designated for assignment, and righty Matt Festa was placed on the 15-day injured list with right elbow tendinitis.  Joining the roster from Triple-A Tacoma are right-hander Riley O’Brien and left-hander Danny Young, with Young’s contract being officially selected.  In addition, recently-designated right-hander Matt Koch has cleared waivers and been outrighted to Triple-A.

Brash has never pitched at the Triple-A level before, as the Mariners made the aggressive move of adding him to the Opening Day roster after an impressive Spring Training.  A rather lightly-regarded prospect who was acquired from the Padres in 2020, Brash exploded into top-100 notoriety with a very impressive 2021 season with the Mariners’ high-A and Double-A affiliates.

Results were far more mixed for Brash in his first taste of the bigs, however.  Brash has a 7.65 ERA over five starts and 20 innings, with almost as many walks (17) as strikeouts (19).  Yesterday’s start against the Astros saw Brash allow four runs over three innings, walking four batters and striking out three.

With Brash heading to Triple-A for more seasoning, Seattle has a hole to fill in the rotation.  The M’s have a few days remaining to figure out their plans, whether they’ll go with a bullpen game for Brash’s next scheduled start or whether another Triple-A call-up could be in the works.  Asher Wojciechowski, Daniel Ponce de Leon, and Darren McCaughan are all getting starts for the Rainiers but none have pitched particularly well, and Margevicius is now headed to the DFA wire.

Margevicius has also struggled, posting a 12.75 ERA over four starts and 12 innings at the Triple-A level.  A veteran of three MLB seasons, Margevicius is trying to work his way back from thoracic outlet syndrome surgery, and it isn’t surprising that the southpaw is still getting on track following that major procedure.  With this recent surgery in mind, teams might not claim Margevicius, allowing Seattle to slip him through waivers and outright him off the 40-man roster.

Festa is also no stranger to health issues, as he missed all of the 2020 season and most of 2021 after undergoing Tommy John surgery.  With this past procedure in mind, any sort of elbow problem is especially concerning, though tendinitis is usually a relatively minor problem.  After tossing 30 2/3 innings for the M’s in 2018-19, Festa made it all the way back to the Show this season, but had only a 5.25 ERA over 12 relief innings.

Though O’Brien has only worked as a reliever over six Triple-A appearances this season, he might also factor into the Mariners’ rotation picture given his track record as a minor league starter.  Acquired from the Reds back on April 17, O’Brien has a 3.36 ERA over 353 1/3 innings in the minors, mostly in the Rays organization from 2017-19.  O’Brien made his big league debut in cup-of-coffee fashion last season, tossing 1 1/3 innings in a single game for Cincinnati.

Now in his seventh pro season, Young is lined up to make his first MLB appearance.  Young was an eighth-round pick for the Blue Jays in the 2015 draft, and has worked almost exclusively as a reliever over his 280 1/3 innings in the Toronto, Cleveland, and Seattle farm systems.  While mostly a grounder specialist during his career, Young has boosted his strikeout numbers since the canceled 2020 minor league seasons, and has a 26.1% strikeout rate over 70 Triple-A frames (though also with a 5.14 ERA in Triple-A ball).  Anthony Misiewicz is the only other left-hander in the Mariners’ bullpen, so Young should get some looks against lefty batters.

Mariners Designate Matt Koch For Assignment, Reinstate Mitch Haniger

By | at

The Mariners announced Friday that they’ve reinstated right fielder Mitch Haniger from the Covid-related injured list and designated righty Matt Koch for assignment in order to open a spot on the active and 40-man rosters.

Haniger, who paced the Mariners with 39 home runs in 2021, was out to a slow start in eight games before he tested positive for Covid-19 on April 16. Haniger missed nearly two weeks’ time and 11 games, and earlier this week told reporters that he was still not quite back up to 100% (Twitter link via Daniel Kramer of MLB.com). He’s apparently back in playing shape now and will return to the lineup and look to improve upon the .176/.200/.471 slash he posted through his first 35 trips to the plate.

The return of Haniger will only deepen a Mariners lineup that has been among the most productive collective units in Major League Baseball so far. The M’s rank eighth in the Majors with 88 runs scored and have the game’s third-best wRC+ at 123, indicating their lineup has been 23% better than average on the whole. Seattle hitters currently lead the Majors with an 11.1% walk rate, and they’re seven in home runs even without Haniger’s powerful bat. He’ll slot back into the outfield/designated hitter mix and ought to jump right back into the heart of the batting order.

Koch, 31, appeared in four games with Seattle and pitched 4 1/3 innings. He allowed four runs on five hits (two homers) and a walk, striking out three hitters along the way. Koch has appeared in parts of five big league seasons, all coming with the D-backs prior to his Mariners debut this season. He was a serviceable arm out of the Arizona bullpen from 2016-18, pitching to a 4.04 ERA — albeit a mark that was not supported by the underlying metrics. Koch’s 13.9% strikeout rate and 1.72 HR/9 mark during that time were both considerably worse than the league average.

The Mariners will have a week to trade Koch, place him on outright waivers or release him.

Mariners Select Matt Koch

By | at

The Mariners announced they’ve selected righty Matt Koch onto the big league roster. Veteran reliever Sergio Romo has been placed on the 10-day injured list, retroactive to April 12, due to shoulder inflammation. To create space on the 40-man roster, Seattle transferred Casey Sadler to the 60-day IL.

Koch is back in the majors for the first time since 2019. A former 3rd-round pick of the Mets, he was traded to the Diamondbacks in August 2015. Koch made his MLB debut the following season, the first of four straight in which he’d pick up some big league time. The majority of his work came in 2018, when Koch started 14 of his 19 outings and tossed 86 2/3 innings of 4.15 ERA ball for the Snakes.

Underlying numbers didn’t support Koch’s capable run prevention figure that season, though, and he couldn’t replicate it in nine outings as a multi-inning reliever the following year. The Louisville product allowed eight home runs in 20 2/3 innings in 2019, and Arizona outrighted him off the 40-man roster that May.

Koch spent the 2020 season with the Yakult Swallows in Japan before returning to affiliated ball last season. He worked 63 1/3 frames as a long relief option for the Indians’ top affiliate in Columbus, posting a 5.83 ERA with a subpar 18.8% strikeout rate. Cleveland never gave him an MLB look, but he signed a minors pact with the M’s this past offseason. Assigned to Triple-A Tacoma to open the year, the 31-year-old has punched out five of the six batters he faced to earn a return call to the big leagues. Koch is out of minor league option years; now that he’s back on the 40-man roster, Seattle has to keep him in the majors or designate him for assignment.

The Mariners signed Romo to a $2MM deal in March. The reliable veteran has tossed a pair of scoreless outings to start his tenure in the organization, but that’ll be put on hold while he recovers. The team didn’t provide a timetable for his return. Sadler, meanwhile, is out for the season after undergoing shoulder surgery last month. His eventual placement on the 60-day IL was a mere formality.

Ryan Divish of the Seattle Times first reported the move.

Minor MLB Transactions: 5/10/21

Catching up on some minor league moves from around baseball…

  • The Astros have signed righty Michael Kelly to a minor league pact, Chandler Rome of the Houston Chronicle tweets. Kelly was the 48th overall pick of the Padres in the 2011 draft, but he hasn’t made it to the bigs thus far. Along with the Padres, the 28-year-old appeared in the minors with the Orioles through 2018, recording a 5.35 ERA over 607 2/3 innings. Kelly’s most recent professional action came in 2019 with the Southern Maryland Blue Crabs of the independent Atlantic League.

Earlier updates:

  • The Dodgers signed right-handers Kevin Quackenbush, Austin Bibens-Dirkx, and Aaron Wilkerson to minor league contracts earlier this month, and all are on the roster for the team’s Triple-A affiliate.  Quackenbush is the most experienced of the trio, with 207 2/3 MLB innings with the Padres and Reds from 2014-18, and the 32-year-old is back in the Dodgers organization after previously pitching for Triple-A Oklahoma City in 2019.  Bibens-Dirkx was a member of several organizations before catching on with the Rangers in 2016 and posting a 5.27 ERA over 114 1/3 innings from 2017-18.  Wilkerson appeared in parts of three Major League seasons with the Brewers from 2017-19, posting a 6.88 ERA over 35 1/3 frames of work.
  • The Indians signed right-hander Matt Koch to a minor league deal back in April.  Koch pitched for the Yakult Swallows in 2020, posting a 7.88 ERA over 16 innings with the Japanese club.  Formerly a member of the Diamondbacks, Koch pitched 86 2/3 of his 125 1/3 career Major League innings in 2018, when he had a 4.15 ERA/4.85 ERA while starting 14 of his 19 games for Arizona.  For his overall career, Koch has a 4.88 ERA at the big league level.

Former MLB Players In NPB: Japan Central League

By | at

Japan’s Nippon Professional Baseball is targeting a June 19 Opening Day. As is the case with the Korea Baseball Organization, the league has plenty of recognizable names for MLB fans to follow as we await the return of baseball in North America. NPB is larger than the KBO (12 teams vs. 10) and has slightly lesser restrictions on foreign players. As such, I split the “names to watch” rundown into two posts — this one covering the Japan Central League and a prior post on the Japan Pacific League.

Yomiuri Giants (77-64-2 record in 2019):

  • Hisashi Iwakuma, RHP: Perhaps the most well-known player on this list, Iwakuma was a rock in the Mariners’ rotation from 2012-16 before shoulder injuries interrupted a very strong MLB run. He signed with NPB’s Giants in the 2018-19 offseason but was only able to throw two minor league innings last year. Now 39, he’ll take another shot at a return in 2020.
  • Gerardo Parra, OF: The man who brought “Baby Shark” to Nationals Park and celebrated a World Series win last October took an early free-agent deal with the Giants back on Nov. 20. The 33-year-old batted .250/.300/.447 with the Nats last year.
  • Rubby De La Rosa, RHP: Once considered to be among the game’s top pitching prospects, the now 31-year-old De La Rosa had a decent run with the Red Sox and D-backs from 2014-17 before injuries derailed his career. He made his NPB debut with the Giants last year, pitching to a 2.25 ERA with a 32-to-5 K/BB ratio in 24 innings.
  • Angel Sanchez, RHP: Pirates fans are excused if they don’t remember Sanchez’s brief 12-inning cup of coffee from the 2017 season. Sanchez, now 30, had a very promising 2015 between Double-A and Triple-A before his 2016 season was lost to Tommy John surgery. He’s spent the past two years with the KBO’s SK Wyverns, including an impressive 2.62 ERA with 8.1 K/9 against 2.3 BB/9 in 165 innings in 2019.
  • Thyago Vieira, RHP: The 26-year-old Vieira was an intriguing prospect with the Mariners and White Sox due to his huge fastball velocity, but he was hit hard in 25 2/3 MLB frames and in the upper minors. This will be his first season in Japan.

Yokohama DeNA BayStars (71-69-3):

  • Jose Lopez, 1B: Yes — it’s that Jose Lopez. An All-Star second baseman with the Mariners way back in 2006, Lopez is now 36 years old and a seven-year veteran in NPB. In two seasons with the Giants and five with the BayStars, he’s a .276/.317/.500 hitter with 186 home runs.
  • Spencer Patton, RHP: The 32-year-old hasn’t pitched in the big leagues since 2016 and has just a 6.26 ERA in 54 frames between the Rangers and Cubs. But Patton has made a name for himself with the BayStars, for whom he pitched to a combined 2.64 ERA in 116 innings from 2017-18. He had a down year in ’19 and will be looking for better health and better results in 2020.
  • Edwin Escobar, LHP: Still just 28, Escobar hasn’t pitched in the Majors since a 2016 cameo with the D-backs. That’s due largely to the success he’s found in Japan, where he’s logged a 3.36 ERA with 9.5 K/9 and 3.4 BB/9 in three seasons out of the BayStars’ bullpen.
  • Tyler Austin, OF: Austin has shown plenty of power in parts of four MLB seasons, but his strikeouts have limited him to a .219/.292/.451 overall batting line. The former Yankees prospect will be suiting up for the first time in NPB this season.
  • Neftali Soto, INF/OF: The 31-year-old Soto saw all of 44 MLB plate appearances with the Reds in 2013-14, but he’s hit like a star in Japan. In two seasons with the Yokohama club, he’s batted .288/.355/.594 with 84 home runs inn 1043 plate appearances. He’ll be a free agent next year and could potentially draw some MLB interest.

Hanshin Tigers (69-68-6):

  • Kyuji Fujikawa, RHP: The now 39-year-old Fujikawa never took off after signing with the Cubs for the 2013 season. He returned to NPB in 2016 and has regained his status as a high-end reliever with his original club, the Tigers. Fujikawa whiffed 83 hitters and posted a 1.77 ERA in 56 innings last year.
  • Kosuke Fukudome, OF: Another former Cub, Fukudome is still chugging along at 43 years old. He hit .256/.347/.394 in 403 plate appearances with the Tigers last season — his 16th in NPB.
  • Justin Bour, 1B/DH: Bour blasted 92 home runs in a six-year run with the Marlins, Phillies and Angels, but he never hit much upon leaving Miami. His power should play well in his NPB debut this year, and hopefully his “Bourtobello Crushroom” nickname catches on there (even though Bour told Sports Illustrated he’s never actually been called by that nickname, it still appears on his Baseball-Reference page).
  • Jon Edwards, RHP: Edwards, 32, has seen MLB time with the Rangers, Indians and Padres but never cemented himself as a steady contributor. He boasts a 3.08 ERA and 12.4 K/9 in parts of four Triple-A seasons, however. This will be his NPB debut.
  • Onelki Garcia, RHP: Garcia, 30, has just 7 1/3 MLB innings to his name and will return to the Tigers for a second season after struggling to a 4.69 ERA in 103 2/3 frames last year. He did post a strong 2.99 mark with the Chunichi Dragons in 2018.
  • Jefry Marte, 1B/3B: Marte never found his stride in parts of four seasons with the Tigers or Angels from 2015-18, but he posted a .284/.381/.444 slash in his debut effort with Hanshin last season.
  • Jerry Sands, OF: The 32-year-old Sands had a journeyman career in the U.S. but hit at star levels in the Korea Baseball Organization over the past two seasons: .306/.391/.574. He signed with Hanshin this winter and will be making his NPB debut.

Hiroshima Toyo Carp (70-70-3):

  • Kris Johnson, LHP: Johnson, 35, barely got a look with the Pirates or Twins, but he’s been one of Japan’s best pitchers over the past half decade. In five seasons, all with the Carp, he has a combined 2.54 ERA with averages of seven strikeouts and three walks per nine innings.
  • DJ Johnson, RHP: This will be the first NPB season for Johnson, who posted a 4.88 ERA in 31 2/3 innings with the Rockies over the past couple of seasons. As an undrafted player who has also spent time on the indie circuit, the 30-year-old Johnson is cultivating quite the unique baseball career.
  • Tayler Scott, RHP: The second South African-born player to make it to the big leagues — Gift Ngoepe was the first — Scott was hit hard in 16 1/3 frames between the Mariners and Orioles last year. However, the 28-year-old also tossed 16 frames with just one run allowed and a 21-to-3 K/BB ratio with the Orioles’ Triple-A club in ’19.
  • Jose Pirela, OF: Pirela hit well in a half season with the Padres back in 2017, but he’s struggled in the Majors outside that run. He was never able to win the second base gig in San Diego and was lost in the shuffle of their crowded outfield mix. Pirela brings a career .257/.308/.392 MLB slash to his debut season in Japan, but he’s a .311/.362/.493 hitter in Triple-A.

Chunichi Dragons (68-73-2):

  • Dayan Viciedo, 1B: White Sox fans surely remember “The Tank” from his 2010-14 stretch with the South Siders, but he never blossomed into the star they hoped he could. Vicideo hit .254/.298/.424 in just shy of 1800 MLB plate appearances, but he’s a .303/.372/.502 hitter in four seasons as a Dragon.
  • Moises Sierra, OF: Speaking of former White Sox outfielders, Sierra’s run with the ChiSox was much more brief than that of Viciedo. He played 83 games there and 207 total in the big leagues from 2012-18, hitting .235/.287/.362 in the process. Sierra posted outrageous numbers in the Mexican League last year (.355/.464/.572) and will make his NPB debut in 2020.
  • Enny Romero, LHP: Romero pitched quite well for the 2017 Nats but has otherwise struggled in the Majors. He spent most of last season in the Dragons’ rotation, pitching to a 4.26 ERA through 116 1/3 frames.
  • Zoilo Almonte, OF: The 30-year-old Almonte never caught on with the Yankees despite a long look in their farm system, but he’s broken out with the Chunichi club in NPB. In two prior seasons, Almonte is a .323/.372/.491 hitter.

Tokyo Yakult Swallows (59-82-2):

  • Nori Aoki, OF: Aoki may be 38 years old, but he’s still a productive hitter. In 565 plate appearances with the Swallows in 2019, he batted .297/.385/.442 with 16 long balls. That’s more power than he showed in MLB, but his six-year run in the Majors was still quite solid: .285/.350/.387, 10.5 WAR.
  • Alcides Escobar, SS: Aoki’s former Royals teammate will join him for his debut NPB campaign once play resumes in two weeks. The 33-year-old Escobar’s bat tailed off dramatically in his final big league seasons, but he’s a former All-Star, Gold Glove winner and World Series champion.
  • Gabriel Ynoa, RHP: A longtime Mets farmhand, the 27-year-old Ynoa never found much success in the Majors (5.39 ERA in 163 2/3 innings). Ynoa soaked up 110 innings for a disastrous Orioles pitching staff in 2019, but he’ll hope to make more of an impact in his NPB debut.
  • Matt Koch, RHP: Koch, 29, never found his footing in four years with the D-backs or even in Triple-A, but he threw well up through the Double-A level in his career.
  • Scott McGough, RHP: The 30-year-old McGough has just 6 2/3 innings in the Majors, all with the 2015 Marlins, but he was sharp for Yakult in 2019, pitching to a 3.15 ERA with nearly a strikeout per frame in 68 2/3 innings of relief.
  • Albert Suarez, RHP: Once a Rule 5 pick by the Giants, Suarez also saw some time with the Yakult club last season, logging a 1.54 ERA in 17 2/3 frames. He also spent time with their minor league club, but he’ll hope to establish himself further in 2020.
  • Ryota Igarashi, RHP: The 41-year-old Igarashi’s time with the Mets, Yankees and Blue Jays in 2010-12 was ugly, but he’s been a consistently strong bullpen presence in a whopping 17 NPB seasons. Last year’s 2.98 ERA in 42 1/3 frames was a near-match with his 2.93 career mark, although his 5.1 BB/9 mark was a bit of a red flag.

Diamondbacks Recall Tim Locastro, Option Caleb Joseph, Outright Matt Koch

By | at

Per a team release, the Diamondbacks optioned catcher Caleb Joseph to Triple A Reno. Tim Locastro has been recalled to take his place on the roster, while right-hander Matt Koch – DFA’ed over the weekend – has been outrighted to Reno.

While playing all three outfield positions, Locastro went 4-11 over nine games (.364 AVG) in his first stint with the big league club this season. He has continued his hot hitting in Reno, going 17-43 (.395 AVG) with a .458 OBP and five home runs. He was sent down just two weeks ago to make room for Taylor Clarke as the team awaited the arrival of Blake Swihart from Boston. While Clarke only stayed long enough to record one scoreless, 3-inning save, the Diamondbacks have cycled through a number of players in their 25th roster spot since Locastro’s demotion, including Jimmie Sherfy, Jon Duplantier, and Koch before activating lefty T.J. McFarland from the 10-day IL for his first action of the season. Despite the rotating clubhouse door, the D-backs have soared in that time, going 7-2 in their last nine games and 12-4 over their last sixteen.

Joseph, 32, returns to Triple-A as Arizona will make due with only two catchers on the 25-man roster for a time. The former Oriole started five games behind the dish this season, hitting only .176/.176/.235. Carson Kelly (.182/.211/.309) and John Ryan Murphy (.222/.317/.500) should benefit from additional playing time in what is already a fairly widespread timeshare. Kelly has started a team-leading 12 times through the season’s first month, with Murphy starting ten times, Joseph five, and injured veteran Alex Avila starting four times. There’s certainly something to be said for avoiding undue pressure on Kelly early on after he was acquired for team icon Paul Goldschmidt, but after starting slowly with the bat, manager Torey Lovullo may be ready to give Kelly a bigger slice of the pie moving into May. Joseph’s demotion aught to at least temporarily afford Kelly opportunity for regularity, though the Diamondbacks generally prefer to carry three catchers and it’s safe to assume Kelly/Murphy have a limited window to take advantage of the two-man game. Swihart, of course, could serve as a third catcher, but the club has been pretty forthright about their plans to use Swihart primarily in the field.

Koch, meanwhile, heads to Triple-A after struggling through nine games out of the Diamondbacks bullpen. He did soak up some volume for the Snakes, spanning 20 2/3 innings with five multi-inning outings and three appearances of at least four innings. All in all, four home runs allowed certainly contributed to a 9.15 ERA, but he also surrendered more than a hit per inning while striking out only 3.5 K/9. Fun fact: the 28-year-old heads to Reno tied with Detroit’s Spencer Turnbull as the current league leader in hit batsmen with five.

Diamondbacks Designate Matt Koch

By | at

The Diamondbacks have designated right-hander Matt Koch for assignment and recalled righty Jon Duplantier from Triple-A Reno, the team announced.

Koch has been with the Diamondbacks since they acquired him from the Mets in a 2015 trade centering on Addison Reed, but the former has since struggled in the majors. Dating back to his 2016 debut, Koch owns a 4.88 ERA/5.99 FIP with 4.95 K/9, 2.23 BB/9 and a 42.2 percent groundball rate in 125 1/3 innings (36 appearances, 16 starts). Koch got off to a brutal start over 20 frames this year prior to his designation, as he logged a 9.15 ERA with 3.92 K/9, which offset an impressive walk rate (1.74).

The 28-year-old Koch has also fallen flat at the Triple-A level, where he carries a 5.79 ERA with 5.0 K/9 and 2.0 BB/9 in 146 innings. And he’s out of minor league options, which further takes away appeal.
