Carlos Hernandez

Tigers Claim Carlos Hernández

By Darragh McDonald | June 16, 2025 at 2:20pm CDT

The Tigers have claimed right-hander Carlos Hernández off waivers from the Phillies, according to announcements from both clubs. Philadelphia had designated him for assignment last week. Detroit had an open 40-man roster spot due to designating righty John Brebbia for assignment yesterday. Hernández is out of options, so the Tigers will need to open an active roster spot once he reports to the club.

Hernández, 28, has big velocity but hasn’t always been able to translate it into results. After working in a swing role with the Royals from 2020 to 2022, he seemed to be breaking out as a reliever in the first half of 2023. Through August 1st of that year, he had thrown 54 innings with a 3.67 earned run average, 30.2% strikeout rate and 7.4% walk rate.

Unfortunately, he posted a 10.69 ERA in his final 16 innings that year. In 2024, he battled some shoulder soreness and spent the first two months of the season on the injured list. When he was reinstated, the Royals shuttled him to Triple-A and back. He posted a 3.30 ERA in the big leagues that year but with subpar strikeout and walk rates of 20.9% and 12.4% respectively. He also had a 5.40 ERA in his minor league work.

He came into 2025 out of options and didn’t make the Kansas City roster out of camp, which led him to the waiver wire and a claim by the Phillies. He logged 25 2/3 innings for the Phils this year with a 5.26 ERA, 18.7% strikeout rate and 10.6% walk rate. Though he hasn’t been able to execute, the stuff is enticing, with Hernández averaging just under 98 miles per hour on his fastball this year while also throwing a splitter, slider and knuckle curve.

Perhaps the Tigers feel they have a path to help him better harness that stuff. Or perhaps he’s just available when they want a fresh arm. Righty Will Vest departed yesterday’s game due to some discomfort in the pinky finger of his throwing hand, per Cody Stavenhagen of The Athletic. Perhaps he will require a stint on the injured list, opening a hole in the big league bullpen. Since the Tigers had an open 40-man spot anyway, claiming Hernández is perhaps a bit of insurance for Vest.

It’s also possible that the Tigers plan to put Hernández back on waivers shortly with the hope of passing him through unclaimed. The Tigers have the best record in baseball and therefore the final waiver priority, meaning the other clubs just passed on him. Hernández has between three and five years of big league service time, meaning he has the right to reject an outright assignment but would have to forfeit the remainder of his $1.16MM salary in order to do so. For now, he’ll report to the Tigers and try to put some good outings together for them.

Phillies Designate Carlos Hernández For Assignment

By Steve Adams | June 11, 2025 at 9:13am CDT

The Phillies announced Wednesday morning that right-handed reliever Carlos Hernández has been designated for assignment. His spot on the 26-man roster will go to fellow righty Michael Mercado, who’s been recalled from Triple-A Lehigh Valley. Mercado was already on the 40-man roster, so the Phils now have one open spot.

Hernández, 28, came to the Phils via waivers back in spring training. The Royals had attempted to pass the flamethrowing, out-of-options righty through waivers and retain him as a depth arm, but Philadelphia claimed the power-armed, 6’4″ righty in hopes of unlocking what’s long looked like some latent potential.

It hasn’t worked out thus far. In 25 2/3 innings out of Rob Thomson’s bullpen, Hernández has been tagged for 15 earned runs on 32 hits and 13 walks. He’s plunked a pair of hitters as well. The resulting 5.26 ERA is an eyesore, Hernández’s once strong strikeout rate has dipped below average; he’s fanned only 18.7% of opponents against a 10.6% walk rate.

Back in 2023, Hernández looked like a breakout arm in Kansas City’s bullpen in the season’s first half. He was averaging better than 99 mph on his fastball and carried a 3.57 ERA, 30% strikeout rate and 7.1% walk rate into that year’s trade deadline. With the Royals operating as sellers and Hernández performing so well, he even looked like an under-the-radar trade chip for a club that, at the time, didn’t have much to peddle to deadline buyers.

The Royals hung onto Hernández — understandably so; he had four additional seasons of club control remaining — and things went south almost immediately. Hernández served up four runs in his third outing post-deadline, and his season snowballed from there. In 17 innings post-deadline, he was shelled for 20 runs. The strong command he’d displayed evaporated, as he walked more hitters than he struck out in the season’s final two months. Hernández missed about two months the following season due to shoulder troubles. He never required surgery, but his velocity has never returned to his 2023 levels, and his command has never rebounded to the levels we saw in the first two-thirds of the 2023 season.

Now that Hernández has been designated for assignment, the Phillies will either trade him or place him on waivers within the next five days. Waivers themselves are a 48-hour process. Within a week’s time, we’ll know what’s next for the hard-throwing righty.

Royals Outright Nick Pratto, Nelson Velazquez; Phillies Claim Carlos Hernandez

By Nick Deeds | March 23, 2025 at 1:15pm CDT

The Royals have cleared three spots on their 40-man roster, according to a report from Anne Rogers of MLB.com. The club placed first baseman Nick Pratto, outfielder Nelson Velazquez, and right-hander Carlos Hernandez on waivers. Hernandez was claimed by the Phillies, while both Pratto and Velazquez cleared waivers and have been outrighted to Triple-A. The Phillies subsequently announced they’ve designated right-hander Tyler Phillips for assignment to make room for Hernandez on the roster.

Hernandez, 28, is a hard-throwing righty who signed with the Royals out of Venezuela and made his pro debut back in 2017. He climbed the minor league ladder before eventually making it to the majors during the 2020 campaign, although his five-appearance cup of coffee was one to forget with a 4.91 ERA and 6.40 FIP in 14 2/3 innings of work. Nonetheless, he served in a swing role for Kansas City the following year and found success in that role, pitching to a 3.68 ERA and 4.08 FIP across 85 2/3 innings of work. That seemed to hint at a fairly bright future in store for the right-hander, but things didn’t work out that way as Hernandez struggled badly over the next two years with a 6.21 ERA in 126 innings of work as he struck out just 19.8% of opponents while walking them at a hefty 11% clip.

Those struggles were enough to spur a full-time move to the bullpen for Hernandez in 2024, and the results were a clear improvement. On the surface, his numbers looked excellent as he pitched to a 3.30 ERA with a 3.50 FIP in 30 innings of work. With that being said, it can’t be ignored that Hernandez also allowed three unearned runs, struck out just 20.9% of his opponents, and struggled badly at Triple-A when not in the majors with a 5.40 ERA in 26 2/3 innings of work. Most concerning was his walk rate, which ballooned to a career-high 12.4% last year. Those issues left Hernandez without a guaranteed roster spot headed into Spring Training, and with no minor league options left the Royals had no choice but to place him on waivers when his 6.97 ERA in 10 1/3 spring innings did not justify a spot in the club’s bullpen.

That gave the Phillies the opportunity to swoop in an add a high-velocity arm off waivers, though they had to part ways with Phillips in order to do so. The 27-year-old made his big league debut with Philadelphia last season and struggled to a 6.87 ERA in 36 2/3 innings of work split between seven starts and one relief outing. The Phillies will have one week to either trade Phillips or attempt to pass him through waivers. If he goes unclaimed, the club can outright him to the minors as a non-roster depth option. Meanwhile, Hernandez figures to enter the club’s bullpen as a possible long relief option alongside Joe Ross and Taijuan Walker, though the latter could be ticketed for a return to the rotation if Ranger Suarez opens the season on the injured list.

As for Velazquez and Pratto, both are young hitters who have shown promise at points in their careers but have struggled to find consistency at the big league level. Velazquez was acquired from the Cubs at the 2023 trade deadline in exchange for right-hander Jose Cuas and impressed in 40 games down the stretch with the club before stumbling to a lackluster .200/.274/.366 slash line in 64 games last year. Pratto, meanwhile, was the club’s first-round pick in 2017 and once a consensus top-100 prospect, but he’s failed to hit in the majors so far with just a .216/.295/.364 slash line across 144 games at the big league level. Both players will now serve as non-roster depth for the club this year and try to play their way into another big league opportunity at Triple-A.

10 Out Of Options Players To Watch This Spring

By Steve Adams | February 28, 2025 at 11:59pm CDT

One of the most interesting elements of spring training every year, at least for those of us who feast on roster construction minutiae, is the collection of players who are out of minor league options. MLBTR just released a full list of such players earlier today.

In many instances, a player being out of minor league options is inconsequential. Justin Steele, Isaac Paredes and Evan Phillips are among the players who fit that description but are in no risk of losing their MLB roster spot. They're all key players on big league rosters who'd never be in danger of being sent down to the minors anyhow.

However, there are typically a handful of players every spring who are on the roster bubble with their current club but who could be a better fit on a team with less competition in their current position. Most of these players have already had big league opportunities with their current club but whether due to injury or poor performance (or both) have yet to firmly seize hold of a roster spot. As players exhaust their minor league options, they'll tend to face increased competition from younger players progressing through the minor league ranks and/or external additions made via trade or free agency. An out-of-options player who doesn't fit his current roster can still go on to find a more solid role and some success elsewhere. Joey Bart was in just this spot last year and after being squeezed out in San Francisco has emerged as Pittsburgh's starting catcher. The Yankees didn't have a spot for Ben Rortvedt, but he's the Rays' clear No. 2 catcher now.

Let's run through 10 names to keep an eye on this spring. Not all of these players will lose their roster spots, and even some who do might not wind up making an impact elsewhere. But each of the names listed here has some reason to hold a bit more intrigue than many of their out-of-options brethren (players listed alphabetically)...

Royals Place Hunter Harvey On 15-Day Injured List

By Mark Polishuk | August 10, 2024 at 2:53pm CDT

The Royals announced that right-hander Hunter Harvey has been placed on the 15-day injured list (retroactive to August 7) due to mid-back tightness.  Right-hander Carlos Hernandez was called up from Triple-A in the corresponding move.

The back problem has kept Harvey from pitching since August 4, so he’ll get the maximum three days of backdated IL placement time factored into a longer stint on the sidelines.  Clearly Harvey and the Royals were hopeful that some rest would allow for Harvey to heal without the need for a trip to the injured list, but today’s news continues that has been a shaky beginning to the reliever’s tenure in Kansas City.

Acquired from the Nationals just under a month ago, K.C. paid a hefty price to land the righty, giving up both notable infield prospect Cayden Wallace as well as the 39th overall pick in the 2024 draft (the Royals’ Competitive Balance Round selection, which are the only types of draft picks that can be traded).  The Royals were hoping that Harvey could help solidify their bullpen, but he has thus far posted a 6.35 ERA in 5 2/3 innings over four appearances, with four walks and five strikeouts.

These numbers are starkly different from the 4.20 ERA, 26.3% strikeout rate, and 6.3% walk rate Harvey posted in 45 innings for Washington prior to the trade.  The small sample size of Harvey’s time with the Royals must be considered, of course, plus some extra misfortune in the form of a .389 BABIP since he went from D.C. to K.C.  However, while most secondary metrics indicated that Harvey pitched better with the Nats than his 4.20 ERA indicated, he is near the bottom of the league with a 48.3% hard-hit ball rate.

It could be that all of that hard contact was bound to catch up with Harvey eventually, and it surely hasn’t helped that he might’ve been nursing a bad back during some of this time.  Harvey has a long injury history mostly related to arm problems rather than back issues, so hopefully a 15-day absence will fully correct the problem.

Harvey joins a few other Royals relievers on the IL, as John Schreiber and Dan Altavilla are expected back roughly around the end of August and the team is hopeful Josh Taylor can return at some point in September.  The injuries haven’t helped the Royals’ efforts to both improve their bullpen results or their broader goal of reaching the playoffs, and with Harvey out, it puts more pressure on James McArthur and new arrival Lucas Erceg to hold the fort in high-leverage situations.

Royals Select Walter Pennington

By Darragh McDonald | July 5, 2024 at 4:05pm CDT

The Royals announced today that they have reinstated infielder/outfielder Adam Frazier from the injured list and selected the contract of left-hander Walter Pennington. In corresponding moves, they optioned infielder CJ Alexander and right-hander Carlos Hernández. To open a 40-man spot for Pennington, right-hander Dan Altavilla was transferred to the 60-day injured list.

Pennington, 26, signed with the Royals as an undrafted free agent in 2020. That year’s draft was reduced to just five rounds due to the pandemic. Since then, he has been climbing the minor league ladder, getting lots of strikeouts and ground balls but also struggling with command at times.

Last year, he tossed 70 2/3 innings between Double-A and Triple-A, allowing 3.18 earned runs per nine frames. He struck out 25.5% of batters faced and got grounders on more than half of the balls allowed in play, but he also gave out walks at an 11.9% clip. Here in 2024, he’s tossed 53 2/3 innings over 32 Triple-A appearances. He has a huge 35.3% strikeout rate and 52.6% ground ball rate, also reducing his walk rate to 8.8%.

That strong performance will get him called up to the big leagues for the first time. He’ll provide the Royals with a left-handed reliever, one capable of pitching multiple innings per outing. 14 of his 32 appearances this year have been for two innings or longer, with Pennington getting as high as four frames.

As for Altavilla, he landed on the 15-day IL on June 2o due to a right oblique strain. He’ll now be ineligible to return until 60 days from that initial IL placement, which would be the middle of August.

Royals Designate Tyler Duffey For Assignment

By Darragh McDonald | May 24, 2024 at 12:40pm CDT

The Royals announced today that right-hander Carlos Hernández has been reinstated from the injured list. To open a spot for him on the roster, right-hander Tyler Duffey has been designated for assignment. Daniel Álvarez-Montes of El Extrabase reported on X prior to the official announcement that Hernández was coming off the IL.

Duffey, 33, signed a minor league deal with the Royals in the winter. He revealed in March that he underwent surgery to remove a cancerous mole from his left shoulder. He noted at that time that post-surgery checks came back negative but that he would continue to get check-ups during the coming months.

The Royals added him to their big league roster just over a month ago. He has since made nine appearances, throwing nine innings, with five earned runs allowed. His 23.8% strikeout rate in that time is around league average but his 19% walk rate is very high and he also hit one batter. Though his 5.00 ERA isn’t disastrous, it’s possible that it’s been kept low by the fact that he hasn’t yet allowed a home run this year. Given the free passes he’s been giving out, it’s possible the Royals didn’t want to wait around and see his luck run out.

They will now have a week to trade Duffey or pass him through waivers. He had a solid run for the Twins a few years back but has struggled more recently. From 2019 to 2021, he threw 144 innings for Minnesota with a 2.69 ERA, 29.8% strikeout rate, 8.2% walk rate and 44.4% ground ball rate. But his ERA jumped to 4.91 in 2022 and he spent most of last year in Triple-A for the Cubs. He struck out 29.1% of batters faced for Iowa but also gave out walks 12.6% of the time.

If he were to pass through waivers unclaimed, he would be able to reject an outright assignment and elect free agency while retaining what remains of his salary, as a player with more than five years of major league service time.

Royals Notes: Marsh, Lynch, Selby, Hernandez

By Nick Deeds | May 5, 2024 at 10:34am CDT

The Royals have been without right-hander Alec Marsh for just over a week now, but manager Matt Quatraro told reporters yesterday (including MLB.com’s Anne Rogers) that even though Marsh is expected to throw just 60-65 pitches in a rehab start today, the team is hopeful he’ll be able to return to the big league rotation after just one rehab appearance assuming today’s outing goes well.

That timeline would put Marsh, 26 later this month, in line for a minimum stay on the injured list and line him up to take the ball in Anaheim against the Angels on Friday. If the righty is able to return after a minimum stint, it would provide a huge boost to the Royals as they look to capitalize on a hot start that has seen them go 20-14 to this point in the season, putting them just 1.5 games behind the Guardians for the AL Central lead.

Prior to his placement on the shelf due to an elbow contusion late last month, Marsh had been a big part of the club’s success. Through five starts this season, the right-hander sports a sterling 2.70 ERA and a 3.26 FIP in spite of a lackluster 15.9% strikeout rate. While he’s posted a strong 6.5% walk rate to this point in the season, the youngster’s .235 BABIP allowed and minuscule 3.2% home run/fly ball ratio both suggest that regression could be on the way for him, as do his 4.66 xERA and 4.39 xFIP. Even in the event that Marsh’s results regress back to that of a mid-to-back of the rotation arm, however, it would still be a substantial improvement over his rookie campaign. Marsh struggled badly in 74 1/3 innings of work in the majors last year, posting a 5.69 ERA with a near-matching 5.70 FIP despite a 24.9% strikeout rate.

While Marsh prepares for his return to the big leagues, the Royals announced today that they’ve recalled left-hander Daniel Lynch IV, optioning right-hander Colin Selby to make room for Lynch on the active roster. Jaylon T. Thompson of the Kansas City Star relayed last night that Lynch was slated to start this afternoon’s game against the Rangers. Lynch, 27, was once a consensus top-30 prospect in the sport but has struggled at the big league level to this point in his career, with a 5.19 ERA and 4.79 FIP in 252 innings of work across 51 starts dating back to his debut during the 2021 season. Those numbers include nine starts at the big league level last year where he posted a 4.64 ERA and 5.17 FIP amid rotator cuff and shoulder issues.

Lynch returned to action during Spring Training but ultimately lost out on the fifth starter role in Kansas City to Marsh, leaving him relegated to the Triple-A level to open the season. He’s struggled badly through six starts at the level this season, posting a 5.86 ERA in 27 2/3 innings of work while striking out just 17.3% of batters faced. Nonetheless, the Royals will turn to him for today’s start, where he’ll take on the tough assignment of facing the reigning World Series champion Rangers.

Marsh isn’t the only pitcher who’s making progress in their attempt to return from the injured list. Per MLB.com’s Injury Tracker, right-hander Carlos Hernandez is beginning to ramp up his activity during a rehab assignment at the Triple-A level after missing the start of the season due to a shoulder impingement. The Royals have mostly enjoyed steady production from their bullpen this season thanks to veteran additions such as John Schreiber, Tyler Duffy, and Nick Anderson, but righty Matt Sauer has struggled badly in a long relief role to this point in the season and the healthy return of Hernandez, who struck out 25.7% of batters faced last year en route to a solid 4.28 FIP, could offer Kansas City a more reliable option for length out of the bullpen.

Dairon Blanco To Undergo Calf MRI

By Darragh McDonald | March 11, 2024 at 5:40pm CDT

Royals manager Matt Quatraro provided some updates today about players on the roster, with Anne Rogers of MLB.com relaying them on X. Outfielder Dairon Blanco, who departed Saturday’s game with some cramping, will get an MRI on his calf today. Quatraro framed it as precautionary, saying the MRI was “just in case.” Meanwhile, right-hander Carlos Hernández is playing catch as he ramps up after being shut down with shoulder soreness a couple of weeks ago.

Though Quatraro downplayed the issue with Blanco, an MRI always implies some level of concern. If healthy, Blanco would likely be in line for a part-time bench role for the club, similar to the job he had last year. He got into 69 games in 2023 but only garnered 138 plate appearances, often entering games as a pinch runner or defensive replacement. He hit a solid .258/.324/.452 in that time for a wRC+ of 108 while also stealing 24 bases in 29 tries.

He was even more impressive at Triple-A, as he stole 47 bases in just 49 games at that level. His huge .347/.444/.451 slash line translated to a wRC+ of 136. He played all three outfield spots, both at Triple-A and in the majors, with his big league glovework getting positive reviews from advanced defensive metrics.

The Royals are likely to give regular playing time to Hunter Renfroe, MJ Melendez, Nelson Velázquez and Kyle Isbel between their three outfield positions and the designated hitter slot. Blanco will be backing up that group and coming off the bench as long as he doesn’t require a trip to the injured list. If he does need to miss some time, it could perhaps open a roster spot for Nick Pratto, Drew Waters or Tyler Gentry.

As for Hernández, as mentioned, he was shut down with shoulder soreness a couple of weeks ago. He played catch over the weekend and will do so again today as he starts to ramp back up. Whether he can be an option for the club early in the season will depend on how he progresses in the next little bit, with Opening Day now just over two weeks away.

Last year, he looked to be breaking out as a key reliever for the Royals. After an outing on August 4, he was sitting on an earned run average of 3.60 through 55 innings on the year. He had a 29.7% strikeout rate, 7.8% walk rate and had earned 11 holds and a save. But he stumbled down the stretch, allowing 19 earned run in his final 15 innings and boosting his season ERA to 5.27.

Hernández will be looking to get back to that excellent form in 2024, though obviously with a strong finish. The year is off to a bit of a shaky start with the shoulder issue but it’s an encouraging sign that he has resumed throwing.

Carlos Hernández Shut Down Due To Shoulder Soreness

By Darragh McDonald | February 27, 2024 at 12:03pm CDT

Royals manager Matt Quatraro provided some updates about the club’s players to Anne Rogers of MLB.com (X links). Right-hander Carlos Hernández will be shut down for a while due to shoulder soreness while left-handed pitching prospect Christian Chamberlain has a torn ulnar collateral ligament.

Last week, it was reported that Hernández had been slowed by the shoulder issue but that the club was still hopeful of him getting six or seven Spring Training appearances before being ready for Opening Day. But per today’s updates, he did not respond well to his recent bullpen and required a cortisone injection. He’ll now be shut down for an undetermined amount of time that the Royals are hoping will be short.

Hernández, 27 next month, seemed to be in the middle of a breakout last year but faded down the stretch. Steve Adams of MLBTR profiled him in mid-July when Hernandez had a 3.86 earned run average, 28.5% strikeout rate and 7% walk rate for the year. But Hernández also had significantly dropped his curveball usage after a couple of rough outings to start the year and saw noticeable improvements. From mid-April to mid-July, he had a 3.12 ERA, 31% strikeout rate and 5.8% walk rate.

Unfortunately, he wasn’t able to finish strong. From the start of August through the end of the season, he allowed 20 earned runs in 17 innings pitched, walking more batters than he struck out. That caused his season-long ERA to finish at an unimpressive 5.27. But his triple-digit fastball velocity and that strong stretch in the middle of last year made him an intriguing breakout candidate heading into 2024.

The shoulder issue could potentially put a damper on that, depending on how Hernández responds to treatment and ramping back up in a few weeks. The Royals have made a number of moves to alter their bullpen this winter, signing free agents Will Smith and Chris Stratton while also trading for Nick Anderson and John Schreiber. Those new guys, as well as incumbents like James McArthur and John McMillon, should give the Royals some cover if Hernández needs to miss some time.

As for Chamberlain, he’s likely looking at a long absence. Based on the reporting from Rogers, it seems like Tommy John surgery isn’t yet guaranteed but is certainly on the table. Now 24, Chamberlain was drafted by the Royals in 2020. Over the past three years, he has climbed through High-A, Double-A and Triple-A, logging a combined 109 1/3 innings over 81 appearances. He has struck out 31% of batters faced but also given out walks at a 19% clip, leading to a 5.60 ERA.

Last summer, Eric Longenhagen of FanGraphs listed Chamberlain as the club’s #19 prospect. The lefty would have been in the mix for a 2024 debut since he had already reached Triple-A but that seems unlikely now. If he does require Tommy John surgery, he would miss the entire 2024 season and likely the early portions of 2025 as well.
