While there’s no suggestion of surgery for either player, it seems they’ll each be in for notable absences. Both injuries figure to force them to begin the season on the injured list. Houston also took hits to their bullpen and outfield depth late last week. Chandler Rome of The Athletic wrote on Friday that righty reliever Kaleb Ort was battling a left oblique issue. Meanwhile, outfielder Taylor Trammell suffered what appears to be a significant right calf strain (per the MLB.com injury tracker).

In isolation, none of those injuries represents a huge blow. León has appeared in seven major league games. He’s likely to start the season with Triple-A Sugar Land once he’s healthy. The former highly-regarded prospect hit 24 homers and stole 29 bases in the minors last season. That came with an elevated 27% strikeout rate. As he enters his age-27 season, he’s unlikely to take a big step forward with his plate discipline. Baseball America ranked him the #18 prospect in a weak Houston farm system. BA writes that León projects as a depth outfielder whose power and speed are undercut by the swing-and-miss issues and fringe outfield defense.

This is a big camp for each of Dubin, Ort and Trammell. All three have exhausted their minor league options. They need to stick on the major league roster (or injured list) or be exposed to waivers. Dubin tossed 45 1/3 frames in a multi-inning relief role last year. He pitched to a 4.17 ERA with solid strikeout (23.7%) and ground-ball (46.5%) rates, but he walked almost 13% of batters faced. The Astros used him mostly in low-leverage relief.

Ort, 33, was a waiver claim from Baltimore last May. He pitched well in 22 big league appearances, working to a 2.55 ERA behind a 28% strikeout rate across 24 2/3 frames. Ort had entered the season with a career earned run average north of 6.00, but he probably showed enough in his relatively small sample with Houston to stick in middle relief. He’s a power arm who can miss bats but had inconsistent control in the minors.

Houston acquired Trammell in a minor league trade with the Yankees at the start of the offseason. The Astros added him to their 40-man roster to keep him from qualifying for minor league free agency. A former top prospect, Trammell has only hit .167/.270/.363 over 126 major league games. He had an impressive .256/.381/.488 line in Triple-A with the Yankees last year. As with León, that came with an alarming number of strikeouts (a 26.8% rate). Houston spent most of the offseason looking for lefty-hitting outfield help after the Kyle Tucker trade. Their only move was to bring back Ben Gamel on a non-guaranteed contract. Trammell and Gamel might battle for one roster spot, espeically with Jose Altuve seeing time in left field.

Gusto, 25, was Houston’s 11th-round pick in the 2019 draft. He’s enjoyed something of a breakout over the past two seasons, as he impressed in 61 1/3 innings of work at the Double-A level last year with a 2.93 ERA and a 24.9% strikeout rate in his first taste of action at the level. That earned him a promotion to the Triple-A level to start the 2024 season, and while he struggled badly in his first taste of Pacific Coast League action this year (8.03 ERA in his first two months) he’s turned things around a big way since then. In 108 innings of work since the start of June, Gusto has dominated opponents with a 2.08 ERA and 23.2% strikeout rate while walking just 6.4% of opponents.

Now, Gusto will get the opportunity to show off what he can do against big league hitters. With both Justin Verlander and Yusei Kikuchi ticketed for free agency this winter, it’s easy to imagine Gusto working his way into consideration for the club’s rotation mix next year as one of the club’s few upper-level arms who have not yet been integrated into the big league rotation. The club figures to have Framber Valdez, Hunter Brown, Ronel Blanco, and Spencer Arrighetti as rotation options headed into next year with plenty of other players due back from the IL sometime next season but Gusto could be an important depth piece for the club come Spring Training, particularly if the club doesn’t make additions to the rotation over the winter.

As for Gamel, the move to place the 32-year-old on the 60-day IL is largely procedural. The outfielder was already on the shelf due to a fractured fibula and considered likely to miss the entire postseason, though today’s roster move confirms that he won’t play again this year. Gamel hit a decent .247/.384/.333 with the Mets and Astros this year and figures to enter free agency this winter as an interesting bench option for clubs in need of outfield depth.

Amaya came to the Astros in a trade from the Marlins back in April, and the 25-year-old’s time on Houston’s active roster has thus far consisted of just a single game — an appearance as a defensive substitute in the Astros’ 10-3 loss to the Yankees on May 7.  At the Triple-A level this season, Amaya has a .221/.308/.330 slash line over 302 total plate appearances with the Astros’ and Marlins’ top affiliates.

This represents a step backwards from the more respectable numbers Amaya has posted in past stints in Triple-A (with the Marlins last season and with the Dodgers in 2022).  Amaya has always been considered more of a glove-first player dating back to his time in the Los Angeles farm system, and while his defense alone might be good enough to get him some consideration for a big league roster, he’ll need to deliver more at the plate to earn anything more than sporadic call-ups or playing time.

Finding a niche in Houston is particularly tricky for Amaya considering how Jose Altuve and Jeremy Pena have the middle infield positions on lockdown, and superutilityman Mauricio Dubon bounces around at several positions.  This is the first time Amaya has been designated for assignment, and so if he clears waivers and is outrighted to Triple-A, he doesn’t have a prior outright or the MLB service time necessary to reject that assignment in favor of free agency.

That comes as little surprise, considering comments from manager Dusty Baker in recent weeks indicating the club didn’t consider a six-man rotation sustainable given the hits the club has taken to its starting depth. This move appears to leave Bielak as the odd man out as Houston reverts to a five-man rotation. While Bielak had pitched to a roughly league average 4.37 ERA in 47 1/3 innings since his call-up to the big leagues at the beginning of May, the move comes as little surprise considering Bielak’s significant struggles since the calendar flipped to June.

Since the beginning of the month Bielak has been shelled for 13 runs (12 earned) in just 16 1/3 innings, leaving him with a 6.61 ERA and a whopping 1.107 OPS against over his past three starts. Struggles with command seem to be the root of Bielak’s troubles, as he’s allowed six walks, four home runs, and hit a batter over that timeframe while recording just nine strikeouts.

Bielak’s woes coincide with what has proved to be a difficult stretch for the Astros. Houston has posted a 4-9 record over the last thirteen games, leaving the club with a 39-33 record that places them third in the AL West, 5.5 games behind the Rangers for the division lead. As the club attempts to right the ship, they’ll trot out a starting five of Framber Valdez, Cristian Javier, Hunter Brown, J.P. France, and Ronel Blanco.

Valdez, Javier, and Brown, of course, starting the season in the club’s rotation and have formed the backbone of a starting staff that ranks 2nd in the majors with a 3.30 ERA in spite of injuries to Luis Garcia, Lance McCullers Jr. and Jose Urquidy. France has played a major role in the rotation maintaining that solid performance, with a 3.42 ERA in 47 1/3 innings for the big league club since making his MLB debut earlier this season.

Blanco is perhaps even more surprising, as the 29-year-old entered the rotation at the beginning of June after struggling badly in his major league debut last season (7.11 ERA in seven appearances) and posting middling numbers as a member of the Houston bullpen earlier this year, with a 4.50 ERA in 12 innings. Since returning to the big leagues as a starter, though, Blanco has recorded two solid outings against solid offenses in Toronto and Anaheim, posting a 3.18 ERA in 11 1/3 innings of work. While Blanco’s 13% walk rate leaves reason for concern going forward, the Astros clearly feel secure enough with his performance to hand him the keys to a rotation spot over Bielak.

Replacing Bielak on the active roster is Dubin, whose first appearance with the big league club will constitute his big league debut. It’s been a long path to the majors for Dubin, who arrived in the Astros organization after they selected him in the 13th round of the 2018 draft. While he managed to post solid numbers in the minors from 2019 to 2021, Dubin has struggled in more recent seasons, with his 4.78 ERA in 58 1/3 innings at the Triple-A level in 2022 ballooning to a figure of 7.96 in 26 innings while repeating the level this season.

Despite those worrisome results, Dubin figures to be an asset to the club’s bullpen while he’s on the roster thanks to his ability to pitch multiple innings. Of his nine appearances at Triple-A this season, Dubin has recorded at least six outs in seven of them. He’ll likely provide long relief for a bullpen that has recently relief on Seth Martinez for multi-inning outings.

Initially selected by the Blue Jays in the 12th round of the 2018 draft, Allgeyer pitched his way to the upper levels of the Toronto system. He earned a cup of coffee at the big league level in 2021, tossing one inning of scoreless relief. The Jays ran him through outright waivers quickly thereafter, however, and he hasn’t made it back to the majors since that point.

For the past two-plus years, the University of Iowa product has mostly pitched in Triple-A. He’s worked in a swing role, starting 36 of 61 appearances. Over 202 1/3 Triple-A frames, Allgeyer carries a 5.34 ERA with a slightly below-average 20.9% strikeout rate and an elevated 11% walk percentage. Allgeyer started four games with the Phils’ top affiliate after signing a minor league contract over the winter. He’s struck out 15 and walked six in 12 innings of six-run ball while keeping the ball on the ground at a solid 48.3% clip.

Allgeyer adds some upper level rotation help to an organization whose starting pitching depth is being tested. Luis Garcia, José Urquidy and Lance McCullers Jr. are all on the injured list. Garcia is done for the year after today’s announcement that he’ll undergo Tommy John surgery. That has pushed Brandon Bielak and J.P. France to the MLB rotation, while some of Houston’s other depth starters are battling injuries of their own.

Righty Shawn Dubin was placed on the minor league injured list today. Former top prospect Forrest Whitley is dealing with minor soreness near his throwing shoulder and will take a day or two off throwing, reports Brian McTaggart of MLB.com (Twitter link). Both Dubin and Whitley are on the 40-man roster, though neither has yet pitched in the majors.

Even after Verlander’s departure, Houston has one of the stronger top-of-the-rotation groups in the sport. Valdez is a borderline Cy Young contender. Javier misses bats at an elite rate and just secured a $64MM contract extension. Garcia and Lance McCullers Jr. have each shown #2/3 starter capabilities in recent years. Urquidy isn’t as high-octane but he’s a perfectly solid back-end starter with excellent control. Just behind that group is Hunter Brown, arguably one of the sport’s five best pitching prospects who allowed only two runs in his first 20 2/3 MLB innings late last season.

It’s a group with immense upside, although the injury bug has already hit before Opening Day. McCullers won’t be ready for the start of the season thanks to a muscle strain in his throwing arm and, as of yesterday, had still not been cleared to begin playing catch (relayed by Chandler Rome of the Houston Chronicle). Even if there doesn’t prove to be a long-term concern, the Astros will surely be without McCullers for a little while in the early going. That, in itself, might not be a huge issue considering Brown can step into the vacated rotation spot. Yet one more injury could start to test Houston’s depth, forcing them to tap into a group of mostly unproven hurlers from the upper minors. Let’s look through some of the depth options whom manager Dusty Baker could need to rely upon if anyone else from his top five goes down.

J.P. France

Despite turning 28 within a week of Opening Day, France has zero MLB experience. The club thought highly enough of him to add him to the 40-man roster in November to ensure they didn’t lose him in the Rule 5 draft, however. The 6’0″ righty started 15 of 34 outings with Triple-A Sugar Land last season, working to a 3.90 ERA with a strong 28.3% strikeout percentage but a concerning 10.6% walk rate in 110 2/3 innings. Baseball America slotted him as the organization’s #21 prospect this winter, praising his deceptive delivery and a five-pitch mix of mostly average stuff but raising questions about the consistency of his strike-throwing.

Forrest Whitley

Once regarded by many as the sport’s most talented pitching prospect, Whitley has seen his stock plummet since he reached Double-A as a 20-year-old five seasons back. He’s now 25 and still hasn’t gotten to the big leagues, though the Astros have kept him on the 40-man roster over the past two seasons. He underwent Tommy John surgery in March 2021 and lost a good chunk of the last couple years rehabbing. Whitley returned for ten outings in Sugar Land, serving up a 7.09 ERA while walking almost 16% of opposing hitters in 33 innings.

It’s not uncommon for pitchers to struggle with their control in their immediate returns after a Tommy John rehab, but the clock is ticking for Whitley to establish any kind of role on the Houston staff. He currently has one minor league option year remaining. While the Astros could perhaps petition for a fourth option next offseason in light of Whitley’s injury and a 2018 suspension for a violation of the minor league drug of abuse policy, it’s worth wondering whether they’d hold him on the 40-man roster for another winter if he doesn’t at least take a step forward in Triple-A. Baseball America now considers him the #28 prospect in the Houston system.

Shawn Dubin

Added to the 40-man roster over the 2021-22 offseason, Durbin spent all of last year on optional assignment to Sugar Land. He lost some time to a forearm strain and worked in a hybrid role when he took the mound, starting only 12 of 23 outings. Over 58 1/3 frames, he posted a 4.78 ERA with an excellent 32.1% strikeout rate but an untenable 12.9% walk rate. Barring a major step forward with his control, he’d figure to be more of a bullpen option for the big league club. BA slotted him 25th in the organizational prospect list, projecting him as a multi-inning reliever.

Brandon Bielak

Unlike the three pitchers above him on this list, Bielak has some MLB experience. He’s appeared in 45 games over the past three seasons but started just eight, none of which came last year. Soon to be 27, the 6’2″ righty has a 5.15 ERA over 94 1/3 career big league frames. He continued to work mostly as a starter in Triple-A, opening 14 of his 23 appearances last year. In 88 2/3 innings there, he put up a strong 3.15 ERA but with more middling strikeout and walk numbers (22.2% and 11.1%, respectively). Bielak has held a 40-man roster spot since the summer of 2020 and has one option year remaining.

Bryan Garcia

Signed to a minor league contract with a non-roster Spring Training invitation, Garcia had been a reliever for his entire career until the second half of last season. The Tigers stretched him out as a starter in Triple-A in the middle of July. Garcia made 11 starts for their top affiliate in Toledo and took the ball four times at the big league level. While he only allowed eight runs in 20 1/3 MLB innings, he had a pedestrian 17:10 strikeout-to-walk ratio. Detroit cut him loose at season’s end, sending him to minor league free agency after he went unclaimed on waivers.

Each of this group logged some upper minors work last season, mostly in Double-A. They’ve all garnered fairly recent consideration in the back half of the Astros’ top 30 organizational prospects but none is seen as an obvious rotation piece for 2023. Any of the trio could pitch their way into consideration at some point but they all figure to begin the year in the minors, particularly since none has yet claimed a spot on the 40-man roster.

——————————-

It isn’t a group of depth starters with much big league experience. While that might not be a pressing concern out of the gate, it’s virtually unheard of for a club to navigate a 162-game schedule reliant upon only five or six starters. Between McCullers’ injury and perhaps a desire to keep an eye on Brown’s workload — he threw 126 1/3 innings last season between Triple-A and the big leagues — it stands to reason the front office could still look into an addition or two.

Players like Chris Archer, Dylan Bundy and Michael Pineda remain unsigned and look like minor league deal candidates at this stage of the offseason. Bringing in someone from that group or scouring the waiver wire for help would make sense for first-year general manager Dana Brown, who has spoken a few times about his desire to stockpile as much rotation depth as possible. The Astros have enough impact talent at the top of the staff they don’t need any splashy acquisitions but there’s plenty of room to augment the group in the upper minors with a veteran.

Peña is the most notable of the group, as he’s regarded by both FanGraphs and Baseball America as one of the top two prospects in the Houston system. Originally a third-round pick out of the University of Maine in 2018, Peña has handily outperformed that draft status as a professional. Always regarded as a high-end defensive infielder, the right-handed hitter has offered quite a bit more than expected at the plate over the past few seasons. He’s been an above-average hitter at every minor league stop by measure of wRC+.

While Peña’s still regarded as a glove-first prospect, his plate discipline and passable raw power should give him a chance to be an everyday shortstop in the future. The 23-year-old missed most of this past season recovering from wrist surgery but returned late in the year to hit .287/.346/.598 with ten homers over 133 plate appearances with Sugar Land. That came with an elevated 26.3% strikeout rate, and the Houston front office may want to give him a little more time at the minors’ top level before he makes his big league debut.

Still, Peña was a lock to be protected from the Rule 5, and it seems he’ll be in the majors before too long. With Carlos Correa potentially departing in free agency, the Astros have to weigh how confident they are in Peña’s ability to assume a key role on a contending club in 2022. The front office’s confidence in the talented youngster could well impact how hard they try to retain or replace Correa this offseason.

Perez was a second-round pick out of a Florida high school in 2017. Primarily a third baseman, he draws praise for his power and arm strength but has some questions about his bat-to-ball skills. The 22-year-old mashed over 109 plate appearances with High-A Asheville this year. He hit at an average .267/.322/.420 clip with eight homers and a 26.1% strikeout rate over 307 plate appearances upon a promotion to Double-A Corpus Christi. BA placed the right-handed hitter sixth in the Astros’ system midseason.

Dubin, 26, was a 13th-rounder in 2018 out of Georgetown College in Kentucky. The right-hander has posted strong numbers in a swing capacity over his pro career, topping out at Sugar Land this past season. BA credits him with a low-mid 90s fastball and plus slider, in addition to a fringe-average curveball and changeup. BA suggests he has a chance to stick as a starter, while FanGraphs’ Eric Longenhagen wrote that he’s likelier to end up in relief. Either way, Dubin’s bat-missing abilities should get him a major league look relatively soon. He punched out 35.4% of opponents against a 9.7% walk rate in 49 2/3 Triple-A innings this year, working to a 3.44 ERA in the process.

Bermudez, meanwhile, was a 23rd-rounder out of Southeastern University in that same 2018 draft. The 26-year-old southpaw has never appeared on an organizational ranking at FanGraphs or BA, but he’s the owner of a strong minor league resume. He split the 2021 campaign between the minors’ top two levels, working to a 3.24 ERA over 111 innings. Bermudez punched out a lofty 31.9% of batters faced while walking just 7.4%, setting himself up for a potential big league debut in 2022.

Nova was formerly one of the top prospects in the organization as well. He’s struggled with underperformance and injuries in recent seasons, and he underwent surgery to repair an ACL tear in September. The 21-year-old will remain in the organization and hope to work his way back onto the 40-man roster once he’s healthy.
