Diamondbacks Move Luke Weaver To 60-Day IL, Select Ryan Buchter

By Connor Byrne | May 27, 2021 at 4:51pm CDT

The Diamondbacks have transferred right-hander Luke Weaver to the 60-day injured list, selected lefty Ryan Buchter and optioned righty Corbin Martin, per a team announcement.

Weaver landed on the 10-day IL with a strained shoulder on May 18, at which point he seemed optimistic he wouldn’t miss a significant amount of time. However, he will indeed be out for the foreseeable future, as the move to the 60-day IL means Weaver won’t come back until at least the second half of July.

This injury is yet another worrying setback for Weaver, who missed a large portion of 2019 with forearm and UCL injuries. Weaver appeared to be coming into his own that year, his first with the Diamondbacks after they acquired him from the Cardinals in the Paul Goldschmidt trade, but he hasn’t returned to form since. Weaver threw 52 innings of 6.58 ERA/4.52 SIERA ball last year, though he has logged a better 4.50 ERA/4.18 SIERA in 40 frames this season. The 27-year-old was also rather effective in his two most recent starts, in which he combined for 10 1/3 scoreless innings and gave up five hits with nine strikeouts against two walks, but it will be quite some time before he’s able to build on that.

Buchter, 34, inked a minor league pact with the Diamondbacks last winter after throwing a meager six innings as an Angel a season ago. Historically, Buchter has been a more-than-capable reliever with a few teams in the majors, where he has logged a 2.90 ERA with a 26.8 percent strikeout rate and an 11.2 percent walk rate over 220 frames. Buchter’s fielding-independent marks haven’t been as promising, yet he has still found a way to limit left-handed hitters to a .189/.269/.351 line and hold righties to a .209/.317/.378 mark.

D-backs To Promote Corbin Martin, Place Luke Weaver On Injured List

By Steve Adams | May 18, 2021 at 12:06pm CDT

The Diamondbacks will place right-hander Luke Weaver on the 10-day injured list following his recent shoulder discomfort and call up right-hander Corbin Martin to make his team debut in one of the remaining games of this four-game set against the Dodgers, John Gambadoro of Arizona Sports 98.7 FM reports (via Twitter).

Weaver, 27, exited his most recent outing with shoulder discomfort but expressed optimism after the fact that he could remedy the issue with a change to his mechanics. At the time the righty was optimistic that he’d avoid the injured list, but Gambadoro indicates that Weaver won’t make his scheduled start against the Rockies on Friday and is indeed IL-bound.

Acquired from the Cardinals as part of the Paul Goldschmidt trade, Weaver had an up-and-down season so far, sandwiching four ineffective starts between four pretty strong outings — two on either end of that rough stretch. Overall, the former first-rounder has a 4.50 ERA through 40 innings with a slightly below-average 22.8 percent strikeout rate but a better-than-average 7.8 percent walk rate. He’ll join Zac Gallen and Taylor Widener on an increasingly crowded D-backs injured list that also currently holds position players Ketel Marte, Asdrubal Cabrera, Christian Walker, Carson Kelly and Kole Calhoun.

Turning to the 25-year-old Martin, his promotion is of plenty note for the D-backs, who thought highly enough of the 2017 second-rounder to make him one of the key pieces they received from the Astros in return for Zack Greinke. Martin was on the injured list at the time, having undergone Tommy John surgery earlier in the 2019 season, but he entered that year regarded as one of the game’s 100 best prospects, ranking 78th at Baseball America and 81st at MLB.com. Eric Longenhagen of FanGraphs currently ranks Martin as the D-backs’ No. 6 prospect and the No. 114 prospect in baseball.

Martin did get his feet wet with the ’Stros before falling to that UCL injury, albeit in a small sample of 19 2/3 innings. He was roughed up for 14 runs in that time (two unearned), but his prospect pedigree and excellent minor league track record give plenty of hope that he can eventually be a big piece of the Arizona staff. He’s tossed 9 2/3 innings in Triple-A Reno this year and yielded only two runs with a 14-to-6 K/BB ratio.

The 2019 injury, the canceled 2020 minor league season and the delayed 2021 minor league campaign have all combined to limit Martin to a total of 201 2/3 innings in the minors, but he’s excelled at every level. The righty carries a career 2.54 ERA, a strong 27.8 percent strikeout rate, an 8.4 percent walk rate and a hearty 53.2 percent grounder rate in that time. He’s been as effective in Triple-A as he was in Double-A, logging a 2.87 ERA with 59 punchouts in 47 innings, although his 24 walks at that level are a bit more troubling. That’s the only level at which Martin has struggled with free passes, though, and scouting reports generally give him credit for average or above-average command.

Given last year’s lack of innings and the fact that he’s working back from major elbow surgery, Martin will probably see his workload managed rather judiciously in 2021. Still, his promotion gives the D-backs and their fans a first glimpse at a pitcher the club hopes can be a prominent contributor to the starting staff for the foreseeable future. If he sticks on the MLB roster this year, the D-backs would control him all the way through the 2025 season, but future optional assignments could push his free agency back even further.

NL West Notes: Martin, Giants, Ubaldo

By Steve Adams | April 2, 2020 at 8:42pm CDT

Right-hander Corbin Martin, one of four players the Astros sent to Arizona in the Zack Greinke blockbuster, had been on the Diamondbacks’ radar for awhile, writes Zach Buchanan of The Athletic (subscription required). They’d first targeted him in the 2017 draft and again in trade talks with the ’Stros centered around Paul Goldschmidt — but Houston wasn’t keen on including him in such a deal. At the time, Martin was 22 and fresh off 122 innings of 2.51 ERA ball between Class-A Advanced and Double-A, while Goldschmidt only had a year of control left.

Martin made his MLB debut in 2019 but underwent Tommy John surgery in July and was suddenly on the shelf for a win-now Astros club. Thus, D-backs GM Mike Hazen inquired again, and the Astros were more willing to listen the second time around. A package of Martin, J.B. Bukauskas, Seth Beer and Josh Rojas (plus plenty of cash to help offset Greinke’s salary) got the job done. Martin may not be an option for the Snakes until 2021, but he’s a second-rounder with a career 2.58 ERA in the minors who has ranked on Top 100 lists in both of the past two offseasons, making him an intriguing piece down the road. D-backs and Astros fans alike will want to check out the piece for thoughts from Hazen and assistant GM Amiel Sawdaye on the club’s longstanding interest in Martin.

Some more out of the NL West…

  • The Giants’ release of veteran lefty Jerry Blevins only increased the odds of southpaws Jarlin Garcia and Wandy Peralta making the club, notes Alex Pavlovic of NBC Sports Bay Area. Both pitchers hurled five shutout innings when exhibition games were still being played — Garcia with an 8-to-1 K/BB ratio and Peralta with a 10-to-4 mark. Given that Garcia is out of minor league options, he’d appear a particularly likely candidate to secure a spot in the ’pen, although there’s certainly room for both. The Giants claimed both lefties off waivers, with Peralta coming over from the Reds in September and Garcia coming over from the Marlins over the winter. Each has had some success in the Majors and is controllable all the way through the 2023 season should things pan out in the Bay Area.
  • Baseball’s shutdown put Ubaldo Jimenez’s comeback attempt with the Rockies on hold, but the right-hander is open to pitching in the minors if play is able to resume, writes Nick Groke of The Athletic in an excellent column on Jimenez’s unexpected bid to revive his career (subscription required). As Groke details, Jimenez received a “fringy” Major League offer in the 2017-18 offseason but opted to stay home in the Dominican with his pregnant wife and soon-to-be-born child. This offseason, wanting to take one last shot, he called Rockies VP of international scouting Rolando Fernandez about using the team’s complex in the Dominican to refine his mechanics. That eventually turned into a solid Dominican Winter League stint, a minor league deal with the Rox and several weeks serving playing the role of wise old sage to younger Rockies pitchers like German Marquez. Manager Bud Black tells Groke that Jimenez was sitting around 91 mph with his heater early in camp. A comeback at age 36 is a long shot but would make for one heck of an in-season storyline to root for.

Astros Acquire Zack Greinke

By Steve Adams | July 31, 2019 at 4:55pm CDT

In a last-minute trade deadline stunner, the Astros announced that they’ve acquired right-hander Zack Greinke from the Diamondbacks in exchange for right-handers Corbin Martin and J.B. Bukauskas, first baseman Seth Beer and infielder Joshua Rojas. Martin (who is recovering from Tommy John surgery), Bukauskas and Beer are arguably Houston’s three best non-Kyle Tucker and non-Forrest Whitley prospects.

Zack Greinke | Steve Mitchell-USA TODAY Sports

The buzzer-beating trade transforms an already-imposing Astros one-two rotation punch to a genuine postseason powerhouse. The 2019 Greinke trade harkens back to 2017’s acquisition of Justin Verlander for the Astros, and Greinke will now join Verlander and Gerrit Cole as the most formidable 1-2-3 combination in the American League (if not all of baseball).

Greinke is earning $31.5MM in 2019 and is still owed another $10.5MM of that salary between now and season’s end. He’s also under contract in both 2020 and 2021, with a $32MM salary owed to him in each season. Beyond that, he still has multiple payouts on his prorated signing bonus coming his way — $3MM in 2020 and 2021 — and receives a $2MM signing bonus by virtue of being traded. A third of his salary in 2019-21 is deferred and will be paid out in annual payment of $12.5MM from 2022-26, thus reducing at least some of the immediate financial implications for Houston. The Astros are reportedly “only” on the hook for about $53MM of the money that is still owed to Greinke.

Greinke’s six-year, $206.5MM contract with the Diamondbacks, signed in the 2015-16 offseason, set a then-record for the largest average annual salary ever promised to a player. And while the first season of that deal looked to be an ominous step backward from the former Cy Young winner’s Hall of Fame trajectory, he’s righted the ship and then some in the ensuing two and a half seasons.

Dating back to 2017, Greinke has racked up 551 innings of 3.12 ERA ball with 8.9 K/9, 1.7 BB/9, 1.1 HR/9 and a ground-ball rate near 45 percent. He’s been particularly effective in 2019 despite the league-wide home run boom, spinning 141 frames of 2.87 ERA ball with a 0.89 HR/9 average that is actually his lowest since 2015. Greinke was shelled for seven runs in his first start of the season, but over his past 21 outings he has a 2.49 ERA and a 2.77 FIP, underscoring that even with his 36th birthday looming in October, he’s still a bona fide top-of-the-rotation pitcher.

The acquisition of Greinke is all the more vital for the Astros when glancing at their future outlook. Cole is slated to become a free agent at season’s end, as are left-hander Wade Miley and right-hander Collin McHugh. That’s three rotation options all departing, and with Martin undergoing Tommy John surgery and Whitley struggling, the most big-league-ready of Houston’s farmhands suddenly looked less certain to be 2020 contributors. (Whitley certainly still could be, of course.) The organization hopes to have Lance McCullers Jr. back from Tommy John surgery next season, but an immediate return to form is far from a sure thing.

Now, with Greinke and fellow controllable acquisition Aaron Sanchez joining the team, the Astros have a pair of new arms to team with Verlander and whichever internal options are up to the task. (Sanchez, alternatively, could also work out of the bullpen.) Landing Greinke lessens the organization’s urgency to pay top dollar for Cole on the open market as well; Cole himself seems likely to pursue a $200MM+ contract in free agency and seems a good bet to secure $150MM+ even if he doesn’t quite reach that level of rarefied air.

Turning to the Diamondbacks, who entered deadline day with a .500 record and an insurmountable division deficit, the move is the next step toward ushering in a new era of baseball. The D-backs traded face of the franchise Paul Goldschmidt this offseason, landing promising young players Carson Kelly and Luke Weaver as the key pieces in that deal. Now, third-year GM Mike Hazen and his staff have shipped out the team’s ace and cleared a substantial amount of payroll, acquiring a pair of pitchers who entered the season regarded as top 100 prospects in all of baseball: Martin and Bukauskas.

Martin won’t be a factor until late 2020 after undergoing Tommy John surgery, but he’s viewed as a potential midrotation arm with an above-average fastball and an above-average, potentially plus slider. He averaged 95.3 mph on his heater in his brief MLB time this season and posted a 3.13 ERA with nearly 11 punchouts per nine innings pitched in 37 1/3 Triple-A frames before undergoing surgery.

Corbin Martin | Thomas B. Shea-USA TODAY Sports

Because his injury and the subsequent operation came about when he was pitching in Triple-A, Martin is on the minor league injured list and not accruing MLB service time. That’s key for Arizona because it means they quite likely won’t need to have him on the MLB roster or injured list until late 2020, which would theoretically make him controllable through the 2026 season. If the D-backs decide they need a roster spot and promote him to the MLB 60-day IL, that timeline would be subject to change.

Bukauskas, 22,was the 15th overall pick in the 2017 draft and has spent the 2019 season in Double-A. While his 5.25 ERA isn’t particularly impressive, he’s averaged 10.3 K/9 with a solid 47.1 percent ground-ball rate against older, more advanced competition at that level. Over at Fangraphs, Kiley McDaniel and Eric Longenhagen gave Bukauskas the potential for three 60-or-better offerings (on the 20-80 scale) but indicated in their preseason report that durability concerns — he has some back issues stemming from a previous car accident — and command could limit his workload and realization of his considerable ceiling.

Beer, beyond the superlative fun that can be had with his name, is the other big get for the Diamondbacks. Houston’s pick at No. 28 overall in 2018, Beer receives 65 to 70 grades on his raw power in scouting reports and makes more contact than one might expect from a prototypical slugger. He’s ripped through Double-A pitching in 2019, hitting at a .299/.407/.543 clip with 16 home runs and nine doubles. He’s also walked at an 8.6 percent clip against a 20.7 percent strikeout rate. Beer has bottom-of-the-scale speed but could be a bat-first option for Arizona at first base (or at designated hitter if it’s ever implemented in the National League — a possibility that continues to be a point of discussion).

Rojas is 25 years old and isn’t regarded as a top prospect, but he’s played all four infield slots and both outfield corners while tearing the cover off the ball in Double-A and Triple-A this season. He’s a potential near-term option for the D-backs who hit .322/.405/.561 in 195 Double-A plate appearances before graduating to Triple-A and raking at a comparable .310/.402/.586 clip. Rojas has a combined 20 home runs and 32 stolen bases this season. He may never have graced top prospect rankings in the past, but at a certain point that level of performance in the upper minors is difficult to overlook. At the very least, he’s an interesting fourth piece who could emerge as a utility option for the Snakes in the not-too-distant future.

Ken Rosenthal of The Athletic first reported (via Twitter) that Greinke was going to Houston. MLB Network’s Jon Heyman, ESPN’s Jeff Passan and the New York Post’s Joel Sherman reported various elements of the return (all Twitter links). Rosenthal and MLB.com’s Steve Gilbert added financial details (Twitter links).

Jeff Luhnow Discusses Astros’ Rotation

By Connor Byrne | July 5, 2019 at 9:51pm CDT

The depth of the Astros’ rotation suffered a blow Friday with the loss of right-hander Corbin Martin, who underwent Tommy John surgery. Not only is the 23-year-old done for 2019, but Astros general manager Jeff Luhnow said Martin is likely to sit out a “significant portion” of next season (via Chandler Rome of the Houston Chronicle). Martin’s absence will cost the Astros a hurler they thought would factor into their rotation in 2020, according to Luhnow.

While Luhnow added that the loss of Martin doesn’t affect the Astros’ plans leading up to the July 31 trade deadline, he admitted that “it could make getting a pitcher with an extra year of control more appealing.”

Owing in part to Martin’s injury, the Astros will head into 2020 with some uncertainty in their rotation. Ace Justin Verlander will stick around, Brad Peacock could either continue to start or return to the Astros’ bullpen, and Lance McCullers Jr. should be back from a Tommy John procedure of his own. On the other hand, though, co-ace Gerrit Cole might depart for a mega-deal in free agency, which would be an enormous shot to Houston’s rotation. Southpaw Wade Miley, who’s been an effective starter for the Astros this year, and righty Collin McHugh are also scheduled to reach the open market.

Even after seeing Martin go down, the Astros still have promising young pitchers who could earn spots on their 2020 staff, with Forrest Whitley, Josh James and J.B. Bukauskas among them. But if the AL West leaders want a more established starter to aid in their World Series push this year and take a spot next season, their solution could come via trade this month.

The Astros had already been connected to the Tigers’ Matthew Boyd in the rumor mill prior to the news on Martin. The 28-year-old Boyd’s a breakout left-hander who’s controllable through 2022, which makes him one of the coveted trade candidates available as the 31st nears. Chris McCosky of the Detroit News added more fuel to the fire Friday, tweeting Houston has “been one of the teams scouting Boyd hard.”

Like Boyd, Blue Jays right-hander Marcus Stroman stands out as an obvious trade chip who’d further a team’s cause past this season. The Astros have reportedly had interest in Stroman, who’s under control through 2020, for multiple seasons. In light of Luhnow’s comments, Stroman may be an even more realistic possibility for the Astros.

Corbin Martin Undergoes Tommy John Surgery

By Jeff Todd | July 5, 2019 at 12:15pm CDT

Astros righty Corbin Martin is down for the rest of the season after undergoing Tommy John surgery, GM Jeff Luhnow told reporters including Chandler Rome of the Houston Chronicle (via Twitter). Martin had been pitching at Triple-A on optional assignment after debuting in the majors earlier this year.

Entering the 2019 campaign, the 23-year-old Martin was graded as one of the game’s top 100 prospects and seen by the Houston organization as a key near-term depth piece. He already took five MLB starts for the club in just his third season as a professional.

Martin wasn’t able to establish himself in the Astros rotation, working to a 5.59 ERA with 19 strikeouts and a dozen walks over 19 1/3 innings. He was done in by the long ball, coughing up eight. But Martin is hardly the first young hurler to have some early hiccups and had turned in good results at Triple-A prior to his promotion.

This injury dents both the depth and the upside of the Houston pitching staff, a strong unit that nevertheless seems a likely area to upgrade at the trade deadline. The loss of Martin comes amidst ongoing uncertainty surrounding Brad Peacock. There are plenty of other options to patch things up for the time being — Jose Urquidy just got the call; Framber Valdez and Cionel Perez are among those available at Triple-A — but it’s hard to imagine the ’Stros won’t look far and wide for new arms. Indeed, it seems that pursuit has already begun.

All indications are that the injury occurred after Martin’s demotion; Luhnow specifically said so this afternoon, in fact. (Via Rome, on Twitter.) If that is indeed the case, then Martin will not accrue MLB service time while he is sidelined. Given the typical year-plus layoff occasioned by a TJ procedure, it’s likely that Martin won’t be seen again at the game’s highest level until late in 2020 or early in the 2021 campaign.

West Notes: Astros, Martin, Rangers, Crouse, Dodgers, Lamet

By George Miller | June 30, 2019 at 4:06pm CDT

Astros right-hander Corbin Martin, who suffered a “potentially serious” elbow injury while pitching in Triple-A, will receive a second opinion “early next week,” according to Chandler Rome of the Houston Chronicle. Rome adds that Astros general manager Jeff Luhnow doesn’t expect Martin to pitch “any time soon,” which certainly is not a promising indicator for the club, though there’s no timetable as of yet. Martin, regarded as baseball’s 48th-best prospect according to MLB.com, debuted earlier this season and enjoyed an impressive debut outing, though he wasn’t able to find much success after that, leading to his demotion to the minors. With Brad Peacock on the injured list and Martin, Framber Valdez, and Collin McHugh all disappointing in their auditions for the final spot in the starting rotation, the scuffling Astros will have to look elsewhere for starting pitching options.

Here’s the latest news from out West…

  • Following the season, Rangers prospect Hans Crouse will undergo surgery to remove bone spurs in his elbow, per Evan Grant of the Dallas Morning News. However, Grant adds, Crouse will continue to pitch at the Class-A level. Crouse, just 20 years old, is ranked as the Rangers’ best prospect and tabbed by MLB.com as the 63rd-best across baseball. A glance at his minor-league numbers suggest that Crouse has performed just fine despite the injury, but it’s certainly a situation worth monitoring for a promising young starter.
  • A couple of injured Dodgers are progressing in their recoveries, reports the Orange County Register’s Bill Plunkett on Twitter. David Freese and A.J. Pollock will each take live batting practice today, with Corey Seager a possibility to join them. Per Plunkett, Freese should rejoin the team this week, with Seager and Pollock due to start rehab assignments in the near future. Jorge Castillo of the Los Angeles Times adds (via Twitter) that Pollock is aiming for a return immediately following the All-Star break.
  • Padres starter Dinelson Lamet is slated to make his long-awaited return to the team in the coming days, writes Kevin Acee of The San Diego Union-Tribune. The right-hander hasn’t pitched in the Majors since 2017, when he flashed tantalizing stuff in his debut season and subsequently missed the entire 2018 season after undergoing Tommy John surgery. He has made six rehab starts this season—three in Single-A ball and three at Triple-A—throwing as many as 85 pitches, a mark that should govern his workload for the Padres down the stretch. The dynamic 26-year-old would boost the Padres rotation, which could be doubly important as Chris Paddack, the team’s best starter, faces questions about his workload.

Injury Notes: Astros, A. Reyes, Cain, Dodgers, Lamet

By Connor Byrne | June 25, 2019 at 9:18pm CDT

Astros right-hander Corbin Martin is dealing with “a potentially serious elbow injury,” Brian McTaggart of MLB.com writes. Martin suffered the injury during a start for Triple-A Round Rock on Sunday. MLB.com’s 48th-ranked prospect, Martin made his major league debut earlier this season when the Astros were looking for a fifth starter, though he wasn’t able to lay claim to the spot. The 23-year-old made five starts and posted a 5.59 ERA with 8.84 K/9 and 5.59 BB/9 in 19 1/3 innings before the Astros optioned him back to the minors.

  • Cardinals righty Alex Reyes has been diagnosed with a strained pectoral muscle that will cost him to two to three starts, according to president of baseball operations John Mozeliak (via Mark Saxon of The Athletic). It’s the latest in a growing line of injuries for the touted Reyes, who, largely because of health issues, hasn’t been able to stay in the majors since his 2016 debut. The 24-year-old has spent almost all of this season at Triple-A Memphis, where he has recorded a 7.39 ERA with 12.21 K/9 and 7.71 BB/9 in 28 innings (10 appearances, seven starts).
  • Brewers center fielder Lorenzo Cain underwent cryptotherapy on his right thumb Tuesday, but it should only keep him out a couple days, Adam McCalvy of MLB.com relays. Cain has undergone the procedure on a few occasions during his career, per McCalvy, who notes the 33-year-old has been battling pain for weeks. That likely helps explain Cain’s surprising decline in production. One of the majors’ most valuable players from 2017-18, Cain’s off to a .253/.314/.357 start in 331 plate appearances this year.
  • The Dodgers are hopeful shortstop Corey Seager will return immediately after next month’s All-Star break, manager Dave Roberts said Tuesday (via Jorge Castillo of the Los Angeles Times and Bill Plunkett of the Orange County Register). Seager would end up missing about a month in that scenario, having gone to the IL with a left hamstring strain June 13. Meanwhile, fellow Dodgers infielder David Freese’s injured hamstring is “not responding like we’d hoped,” Roberts revealed. Nevertheless, the Dodgers are optimistic Freese – who just hit the shelf over the weekend – will come back prior to the break.
  • The Padres could soon have “a serious conversation” about whether to add rehabbing righty Dinelson Lamet to their rotation, per manager Andy Green (via AJ Cassavell of MLB.com). The team’s “getting more and more excited about that concept” of plugging in Lamet, who’s mending from April 2018 Tommy John surgery and may only be one more rehab start from heading back to San Diego. The 26-year-old’s first major league start of the season could come as early as July 4, Cassavell reports. Lamet showed promise in his only big league season, 2017, during which he logged a 4.57 ERA with 10.94 K/9 and 4.25 BB/9 in 114 1/3 innings.

Astros Option Corbin Martin

By Jeff Todd | June 4, 2019 at 5:12pm CDT

5:12pm: The Astros announced that they’ve optioned Martin to Triple-A. It’s not clear who’ll step into his spot in the rotation, as the corresponding move was the recall of lefty reliever Reymin Guduan. As The Athletic’s Jake Kaplan points out (via Twitter), they’ll need a fifth starter on Saturday but can get through the next turn in the rotation with only four starters due to an off day next week.

11:05am: Though the Astros aren’t committing to a rotation change just yet, Chandler Rome of the Houston Chronicle writes that one may not be far off. Corbin Martin has not made it past the fourth inning since his debut outing.

Martin’s first showing was a good one. But in his four intervening starts, he has allowed 10 earned runs on 20 hits with a 10:11 K/BB ratio in 14 innings.

The ’Stros are showing a fair bit of patience, but obviously won’t be satisfied with these sorts of results. Martin has struggled to get ahead of hitters, keep his pitch count down, and stay in the zone. And though the organization can afford some added audition time with a nine-game division lead, it also will be wary of tempting fate while several of its best players are on the injured list.

Skipper A.J. Hinch affirmed that the organization believes in Martin as a long-term option, citing his stuff and “mentality” as reasons for a “really good” long-term outlook. But Hinch says that for Martin “to stay in the rotation and be effective, not just for the foreseeable future but his entire career, it’s important for him to mix in some good outings and make sure he can get us deep in games.” Whether Martin will get one more chance to turn the corner remains to be seen.

The ’Stros certainly have alternatives. Collin McHugh would be an obvious choice, though he’s on the IL. Josh James, Framber Valdez, and Brady Rodgers could all slide over from the bullpen. It’d certainly be easy enough for the team to piggyback a few of those pitchers to get the length needed for a game or two, perhaps allowing one or more pitchers to stretch out fully on the fly.

Looking down on the farm, there are two 40-man starters — Cionel Perez and Rogelio Armenteros — camped out at Triple-A. Neither has been particularly impressive to this point of the season, at least in terms of earned runs, though both have swing and miss capabilities. It might have been hoped that top prospect Forrest Whitley would be ready for a taste of the big leagues, but he has been hammered early on at Round Rock and doesn’t seem likely to be tapped in the near future.

Astros To Shift Collin McHugh To Bullpen, Promote Corbin Martin

By Connor Byrne | May 11, 2019 at 5:24pm CDT

The Astros are moving right-hander Collin McHugh to their bullpen for at least “a few outings,” manager A.J. Hinch told Mark Berman of Fox 26 and other reporters Saturday. They’ll likely promote righty Corbin Martin from Triple-A Round Rock to start in McHugh’s place against Texas on Sunday, Hinch added. Martin’s not on the Astros’ 40-man roster, but because the team has two openings, it won’t need to create room for him.

McHugh’s demotion comes in response to a four-start slump in which his ERA shot from a season-best 1.96 on April 16 to 6.37. In his most recent performance, a 12-2 loss to the Royals on May 7, McHugh yielded eight earned runs on seven hits, including two homers, with three walks and three strikeouts in three innings. The long ball has haunted McHugh for a few weeks, as he gave up eight in his four-start slide after surrendering just one in his first three outings of 2019.

Until this season, home runs hadn’t been a problem for McHugh since the Astros added him off waivers entering the 2014 campaign. He was a quality rotation piece with the club from 2014-17, a 606 1/3-inning, 102-start stretch in which McHugh pitched to a 3.70 ERA/3.60 FIP with a 10 percent home run-to-fly ball rate. McHugh then shifted to the Astros’ bullpen last year, when he was somewhat quietly among the majors’ most effective relievers and where he experienced an uptick in velocity. Despite that, the Astros moved McHugh back to their rotation entering this season because of the departures of Charlie Morton and the still-unsigned Dallas Keuchel to free agency and the Tommy John surgery Lance McCullers Jr. underwent.

As an impending free agent, another good season as a starter could have put the soon-to-be 32-year-old McHugh in line for a respectable payday during the upcoming winter. While there’s still time for McHugh to rebound as a starter or reliever in advance of the offseason, he hasn’t done himself any favors with his bloated HR-fly ball rate (21.6), a sub-40 groundball percentage or a 6.37 ERA/5.17 FIP in 41 innings. To his credit, though, he has registered 9.22 K/9 against 3.07 BB/9.

McHugh’s struggles will create a big league opportunity for the 23-year-old Martin, a native of the Lone Star State and former Texas A&M Aggie whom the Astros chose in the second round of the 2017 draft. That pick, No. 56, was one of the two selections the Astros received from the Cardinals stemming from a hacking scandal.

Martin has held his own at all levels of the minors since he turned pro, especially during 2018 in Double-A, where he posted a 2.97 ERA/3.29 FIP with 8.39 K/9, 2.45 BB/9 and a 47.3 percent groundball rate in 103 innings. That performance earned Martin a promotion to Triple-A to begin this season, and he hasn’t fallen short there either, evidenced by a 1.48 ERA/3.35 FIP with 10.36 K/9, 4.07 BB/9 and another 47 percent-plus grounder mark over 24 1/3 frames.

Thanks in part to Martin’s minor league excellence, both FanGraphs (No. 50) and MLB.com (No. 73) regard the 6-foot-2, 200-pounder as one of baseball’s 75 best prospects. Entering the season, FanGraphs’ Kiley McDaniel and Eric Longenhagen wrote that “Martin sits in the mid-90s, mixes in a plus slider, with an above average changeup and average command,” though they expressed some disappointment in his strikeout numbers. Martin’s now in line to join a Houston staff that, aside from Wade Miley, hasn’t had much difficulty punching out opposing hitters this season.
