Of today’s additions, Hence is the most highly regarded. The 22-year-old finished the season as a consensus top-100 prospect, placing as high as 30th on Baseball America’s rankings and also landing 46th at FanGraphs and 61st at MLB.com. He spent 2024, his age-21 season, pitching at the Double-A level, where he logged a 2.71 ERA in an abbreviated workload.

Hence started just 20 games on the season, tallying 79 2/3 innings while missing nearly all of June and July. The Cardinals didn’t specify the nature of his injury, but Hence departed his June 5 start after two innings, returned to pitch one inning on June 23, and then didn’t return to the mound until July 27. Hence’s season came to an end after he was lifted from a Sept. 11 start following just 1 1/3 innings.

Even with the truncated year, Hence remains one of the minor leagues’ most promising young arms. He set down a whopping 34.1% of hitters on strikes in 2024 and showed average or better command, with an 8.1% walk rate. Hence sits mid-90s with a heater that can climb to 98-99 mph, rounding out his repertoire with one of the best changeups in the minors and a solid slider. There are some durability concerns even beyond this past summer, as he’s yet to reach 100 frames in any season of his professional career. Still, he’s teeming with upside, and his Double-A success could open the door for a big league debut later in 2025 if he can stay healthy.

Roby, 23, has drawn his share of top-100 fanfare as well, though his stock dipped amid shaky results and injury troubles of his own in 2024. FanGraphs ranked him 91th in the game at season’s end, but he’d fallen off most other prominent rankings. The 2020 third-rounder, selected by the Rangers and traded to the Cards in the Jordan Montgomery swap, pitched just 38 1/3 innings with a 6.57 ERA between High-A and Double-A in ’24.

Roby has posted middling ERA numbers in his career but regularly logged impressive rate stats and garnered attention from scouts due to plus raw stuff across the board — headlined by his curveball. Roby needs to improve his command and prove he can handle a starter’s workload, as he’s a bit undersized at 6’1″ and has never reached 105 innings in a pro season.

The 26-year-old Koperniak signed with the Cards as an undrafted free agent in the summer of 2020, following that year’s five-round amateur draft. He spent the whole 2024 season in Triple-A, where he hit .309/.370/.512 with 20 homers, 28 doubles, three triples, five steals, an 8.4% walk rate and an 18.7% strikeout rate. He played all three outfield spots but spent the bulk of his time in left field.

Svanson, 26 in January, was acquired from the Blue Jays in the trade sending Paul DeJong to Toronto. He spent the 2024 season working out of the Double-A bullpen, where he logged 63 2/3 innings of 2.69 ERA ball with a 20.8% strikeout rate, 8.8% walk rate and 52.7% ground-ball rate. He’ll presumably head to Triple-A early in 2025 and is a candidate for a look in the big leagues as soon as this coming season.

Rom, who’ll turn 25 in a few weeks, was acquired from the Orioles in the ’23 trade sending Jack Flaherty to Baltimore. He struggled through eight starts with the Cardinals in 2023, yielding an 8.02 ERA, but missed the entire 2024 season following arthroscopic shoulder surgery. Since he’s already cleared waivers, Rom will stick with the club as a depth option for the upcoming season. He hasn’t had any big league success yet, but he had the look of a potential back-of-the-rotation starter in the Orioles’ system before the shoulder injury ruined his 2024 season.

It’s an incredibly impressive turnaround for Contreras, who was initially expected to miss ten weeks of action after a swing of the bat from J.D. Martinez collided with his forearm back in May. Instead, he was cleared to resume baseball activities just one month to the day after sustaining the injury, and appears to be ramping up fairly quickly. A return before the end of June would place Contreras’s return at just six or seven weeks after the injury, though manager Oli Marmol pumped the brakes on talk of a quick return in conversation with reporters (including those at MLB.com). Marmol noted that the club will monitor how Contreras progresses over the coming weeks and lean on the team’s medical staff as they determine a more specific timeline for his return.

Whenever Contreras ultimately returns, he figures to be a huge asset to the Cardinals. The 32-year-old slugger was slashing an incredible .280/.398/.551 with a 171 wRC+ in 128 trips to the plate at the time of his injury and stood out as the hitter leading a scuffling Cardinals team that fell to a 15-21 record on the day of Contreras’s injury. While their catcher has been on the mend, St. Louis has surged back towards .500 and now sports a 30-33 record that places them just one game back of the final NL Wild Card spot. If St. Louis can manage to hang around the Wild Card race over the next few weeks and Contreras picks up where he left off upon his return, the catcher could help to further transform their offense as they look to establish themselves as contenders ahead of the July 30 trade deadline.

Contreras isn’t the only player progressing towards a return for the Cardinals this month, as veteran southpaw Steven Matz is scheduled to make his second rehab start on Tuesday at the Double-A level as he works his way back from a lower back strain that sidelined him at the end of April. As noted by MLB.com’s Injury Tracker, Matz is slated to throw 40 pitches during his next rehab start, meaning that there still figures to be quite a ways to go until he returns to the big league club. The Cardinals are reportedly planning on stretching Matz out into the 75-80 pitch range before he comes off the IL and steps back into the club’s big league rotation, a goal that will likely keep him on the shelf until sometime near the end of the month if he continues building up at his current pace.

In Matz’s absence, the Cardinals have not been able to settle on a fifth starter to fill the void behind Sonny Gray, Lance Lynn, Kyle Gibson, and Miles Mikolas. The club has used both right-hander Andre Pallante and lefty Matthew Liberatore to follow up that quartet in the weeks since Matz was placed on the shelf, but the duo has combined for a 7.11 ERA across five starts in Matz’s absence. Those struggles have led Marmol to be non-committal regarding who will take the ball when the fifth spot in the rotation is due up tomorrow against the Rockies, though Derrick Goold of the St. Louis Post-Dispatch notes that Marmol has noted the starter will be chosen from “options already on the roster,” indicating that they won’t look toward other alternatives beyond Pallante or Liberatore just yet.

Right-handers Sem Robberse and Adam Kloffenstein are already on the club’s 40-man roster and could theoretically be options to fill out the club’s rotation should St. Louis eventually decide to make a change, but the pair have ERAs of 4.46 and 4.50 respectively at the Triple-A level this year with no big league experience. Cardinals fans are surely hopeful that they’ll see right-hander Tink Hence, the club’s top prospect who has dominated the Double-A level during his age-21 season this year, impact the big league team at some point this year.

Fans hoping to see Hence in St. Louis this season were dealt a scare earlier this week when he was was pulled from his most recent Double-A start after just two innings. Fortunately, MLB.com notes that Cardinals president of baseball operations John Mozeliak told reporters that Hence’s removal was due to cramping rather than any sort of serious issue and that he should be ready to make his next start for the Double-A Springfield Cardinals. Through 11 starts this year, Hence has pitched to a 3.19 ERA with a 2.82 FIP in 53 2/3 innings of work while striking out a fantastic 32.4% of batters faced. It would hardly be a surprise to see those numbers earn Hence a promotion to Triple-A in the near future; after all, St. Louis promoted him from High-A to Double-A after eleven similarly excellent starts last year.

Five Big Hype Prospects

Ethan Salas, 17, C, SDP (A)
139 PA, 6 HR, 5 SB, .259/.381/.500

When we adjourned two weeks ago, Salas was batting .208/.340/.286 in 94 plate appearances. An 82 wRC+ isn’t anything to sniff at when we’re talking about a guy who’s 17-and-one-month old playing in full-season ball. Over the last two weeks, Salas hit .371/.467/.971. Including a HBP, he has as many free passes as strikeouts during the span. Of his 13 hits, he bopped five homers, four doubles, and a triple. That adds up to a 240 wRC+ for the hot streak and a 133 wRC+ on the season. If he keeps this up for long, he’ll find himself playing against High-A competition before the season ends. He’s “on pace” to debut as a teenager – a feat he can accomplish as long as he reaches the Majors before June 1, 2026.

Jackson Merrill, 20, SS, SDP (A+)
300 PA, 10 HR, 10 SB, .280/.318/.444

Salas’ future teammate had to grind through a rough April before turning a corner. The Midwest League is a difficult hitting environment. His first month of play consisted of a .188/.247/.338 performance. In the three months since then, he’s hit .317/.348/.487 while making steady improvements. Lately, he’s found a power stroke. Since June 14, he’s hit six of his 10 home runs. Merrill isn’t expected to be much of a power hitter. His carrying trait is an advanced feel for contact. He rarely meets a pitch with which he can’t connect. His discipline lags a bit, though it’s not as if he’s Javy Baez. An unsubstantiated theory of mine is that his early-season slump was the result of contacting too many pitches outside of the zone. The theory fits what data I have available, though I haven’t discussed it with anybody who would actually know.

Nick Yorke, 2B, 21, BOS (AA)
316 PA, 9 HR, 6 SB, .275/.361/.453

Folks weren’t sure what to make of Yorke’s forgettable 2022 campaign. The industry had a little chuckle when the Red Sox “reached” for Yorke in the first round of the 2020 draft. After a superb 2021 season, everyone adjusted expectations. Then 2022 happened. Some evaluators stuck with their updated outlook and blamed injuries. Others pointed to his subpar defense and wrote him off.

Yorke has rebounded this season – perhaps not enough to make up for his defensive shortcomings. His current 122 wRC+ depends upon a .353 BABIP. He also has 13.0 percent swinging strike and 25.0 percent strikeout rates. Historically, prospects with similar statistical performances have been prone to stalling out in the Quad-A bucket. For now, we should view Yorke’s rebound as a positive development. Perhaps more distance from his injury-riddled 2022 will lead to improvements in his quality or rate of contact.

Tink Hence, 20, SP, STL (AA)
(A+) 41.2 IP, 9.94 K/9, 2.59 BB/9, 2.81 ERA

Hence received a promotion to Double-A at the beginning of July. He also picked up a hold in the Futures Game. The pitching-needy Cardinals surely hope Hence can remain in the rotation. Alas, though he doesn’t walk many hitters, he’s not known for sharp command. His breaking ball is a weapon. It’s expected he should join the many pitchers who have mastered manipulating breaking ball spin for different effects. He doesn’t have a consistent changeup. Taken with the errant fastball command and history of brief outings, the relief risk is palpable. That said, Hence has yet to meet a challenge he hasn’t mastered. His Double-A debut was the first appearance of his career in which he faced more than 20 batters (22).

Coby Mayo, 21, 3B, BAL (AA)
347 PA, 17 HR, 4 SB, .307/.424/.603

With a 176 wRC+ on the season, Mayo is one of the top qualified hitters in the minors. He’ll play his next game in Triple-A, ending a nearly 500-plate appearance stint in Double-A. Mayo has traits grounded in the 2019 juiced ball era. He’s a pull-oriented slugger who generates plenty of loft. As a right-handed hitter, he’s not an ideal fit for Camden Yards. However, his power is such that he could overcome the home field limitations. It will be interesting to see if Mayo can continue to run elevated BABIPs into the Majors as this is a hitting profile typically associated with low BABIPs. Hypothetically, if a franchise-altering talent is made available at the trade deadline, Mayo would go a long way toward securing a deal. They’ll eventually have to trade somebody they like.

Three More

Johan Rojas, PHI (22): The Phillies are angling to get Kyle Schwarber into the DH slot. The plan would involve Cristian Pache in center and Brandon Marsh in left. If Pache doesn’t work out, Rojas has a similar reputation as a superlative defender who might hit enough to create a lot of value. In 354 Double-A plate appearances, Rojas is batting .306/.361/.484 with nine homers and 30 steals. He’s on the 40-man roster.

River Ryan, LAD (24): The latest pitcher to pop in the Dodgers system, Ryan features a promising four-pitch repertoire. In the month of June, he tossed two five-inning no-hitters. His command hasn’t been particularly sharp. Even across those two no-nos, Ryan issued four walks and hit three batters. It’s thought he’ll eventually develop better command. If not, he has a relief floor.

Ignacio Alvarez, ATL (20): A ripped shortstop who recently turned 20, Alvarez evokes Yandy Diaz right down to the comical biceps, low-angle contact, discipline, and rare whiffs. The comparison is hard to avoid. He might just be the next Brave to skip the line to the Majors. He generally keeps the ball on the ground with an all-fields approach. He’s expected to eventually move to third base, though he remains passable at shortstop for now.

Five Big Hype Prospects

Marco Luciano, 20, SS/3B, SFG (A+)
222 PA, 10 HR, .268/.342/.470

Once considered the “next big thing,” Luciano has turned out to be less athletic than originally believed. When he added strength prior to 2021, he lost speed and flexibility. He still has a bright future, but there are a number of questions related to his future position, ability to make contact, and work ethic. Teams can overlook questionable range at shortstop, but Luciano also suffers from an errant arm, making a move down the defensive spectrum more likely. The work ethic concerns seem overblown to me – sometimes players draw negative reviews because they take their failures in stride. Fans, in particular, often equate tantrums with caring and wistful shakes of the head with a lack of care. Scouts too sometimes rush to judgment.

He only has 249 plate appearances this season because he missed over two months with a lower back strain. Since returning on August 4, he’s batting .243/.341/.419 in 85 plate appearances. All told, he’s performed on par with expectations for a 20-year-old top prospect in High-A. His swing is geared for high exit velocity, fly ball contact. He profiles as a future 30-homer threat. Keep an eye on his strikeout rate as he advances into the upper minors next season.

Josh Jung, 24, 3B, TEX (MLB)
(AAA) 106 PA, 6 HR, 1 SB, .273/.321/.525

Listed as a “snub” in last week’s edition of Big Hype Prospects because he wasn’t yet in the Majors, the Rangers have finally called upon their top prospect. Jung was on the cusp of an Opening Day assignment with Texas before an injury held him out until late July. Curiously, he’s actually performed poorly lately. After an initial thrashing of Triple-A pitching, he’s batting just .197/.232/.288 (.300 BABIP) over his last 69 plate appearances. Much of his recent woes can be boiled down to a 1.4 percent walk rate and 36.2 percent strikeout rate, both of which are uncharacteristic.

Jung is a hard contact machine that uses all fields. He generates substantial pull-side power. His overall profile is reminiscent of peak Josh Donaldson – a plus defender who can hit for average and power with a mid-lineup role. Given his ongoing slump, his debut might include a hiccup or two.

Alec Burleson, 23, OF, STL (MLB)
(AAA) 470 PA, 20 HR, 4 SB, .331/.372/.532

With Dylan Carlson on the injured list, the Cardinals get an opportunity to decide if Burleson will be a part of their postseason roster. A 2020 draftee, he raced through the minors without any setbacks. He’s a free-swinger with above-average plate coverage and an ability to use all fields. He’s a below-average runner who might best fit as a designated hitter long term. We might find his aggression is exploited by Major League pitchers. While his swing is often described as uncomplicated or simplistic – a trait usually associated with middling or worse power – Burleson is able to generate plenty of pop. The next step in his development is to improve his swing decisions.

Tink Hence, 20, SP, STL (A)
52.1 IP, 13.93 K/9, 2.58 BB/9, 1.38 ERA

The Cardinals have printed outfielders in recent years, and they’ve historically done well developing pitchers too. Hence has drool-worthy stats in Low-A, though it’s worth noting he’s pitching once every seven days. When he does appear, his outings are brief. He faced 16 batters on September 7 which also happens to be a career-high. He usually sees between 11 and 13 batters. It’s assumed Hence is being handled carefully due to his string-bean frame. He’s listed at 6’1’’ and 175 pounds. The FanGraphs crew compares his appearance to Triston McKenzie (he’s listed 6’5’’ and 165 pounds). For now, we can set workload concerns aside, but he’ll eventually need to work on a five-day schedule and face 20 or more hitters.

Hence wields a fastball and curve that fit the current meta. He works up in the zone with the heater and drops in the curve. It’s worth noting that hitters typically adjust to popular pitching strategies within a couple seasons. Hence might find his approach is less effective in 2025 than similar pitchers are experiencing today. He’s still working to develop a third offering. His changeup remains a work in progress per reports, drawing adjectives ranging from nasty to inconsistent.

Bo Naylor, 22, C, CLE (AAA)
(AA/AAA) 461 PA, 17 HR, 20 SB, .259/.397/.480

Naylor was generally well-regarded as of 2019. After the lost COVID year, he played so poorly in 2021 that some evaluators considered him a bust. Case in point, Baseball America ranked him 59th overall in their August update. When FanGraphs profiled Cleveland’s system in mid-April, Naylor ranked 28th – that’s just among Guardian farm hands.

He responded this season by thriving in Double-A and more than holding his own in Triple-A. The brother of fellow Guardian Josh Naylor, Bo has a discipline-forward approach that includes decent pop and a surprising feel for contact. As a left-handed hitter, he can take advantage of the friendlier aspects of Progressive Field’s park factors. The profile offers shades of former Guardians catching prospect Carlos Santana. Naylor happens to be a plus defender behind the dish, making a move down the defensive spectrum unnecessary. Like Santana, Naylor is liable to combine a poor batting average with a plus on base and slugging percentages. He has above-average foot speed for a catcher.

Five More

Shane Baz, TBR (23): Baz has just 40.1 big league innings split across two seasons so he’s still technically a prospect – and debatably the top pitching prospect. He’s eyeing a late-September or early-October return from an elbow sprain. At his best, he has a potent four-pitch repertoire though he still has room to improve his consistency. If he appears again this season, it will likely be as a high-leverage reliever.

Robert Hassell, WSH (20): A contact of mine casually mentioned a lot of the shine has come off Hassell this season. Despite struggling with the Nationals High-A affiliate, Washington opted to promote Hassell to Double-A based on his larger success with the Padres High-A club. Since arriving in Double-A, he’s batting .221/.310/.312 with a homer and a steal in 87 plate appearances. Personally, I’m starting to get Andrew Benintendi vibes. The swing is “sweet” but the quality of contact is not.

Logan O’Hoppe, LAA (22): O’Hoppe was the standout hitting prospect in the Phillies system heading into the trade deadline. However, Double-A Reading is notoriously hitter-friendly. It was unclear if his breakout was a product of the venue. Fast-forward 101 plate appearances, and it sure seems like O’Hoppe is the real deal. Since joining the Angels, he’s batting .297/.475/.689 with nine home runs and more walks than strikeouts.

Zac Veen, COL (20): Veen thrashed High-A pitching to the tune of .269/.368/.439 with 11 home runs in 400 plate appearances. The carrying trait, however, was his 50 steals in 54 attempts. He earned a promotion to Double-A where he’s made another 108 plate appearances. He’s struggling to adjust to the level – possibly due to fatigue. In 108 plate appearances, he’s batting .196/.269/.258 with one home run and four steals in nine attempts. It’s not super common for 20-year-olds to receive 508 plate appearances. The fatigue explanation passes a smell test.

Noelvi Marte, CIN, (20): It’s been a while since we last checked in on the contentious shortstop. He’s continued to perform well with the Reds, making incremental gains to his plate discipline and contact rates. He’s batting .292/.397/.443 in 126 plate appearances with Cincy’s High-A affiliate. Where he’ll eventually fit in a system that includes the inestimable Elly De La Cruz remains to be seen, but he’s certainly trending towards a long Major League career. Across both franchises, he has 520 plate appearances with a .279/.371/.458 triple-slash, 19 home runs, and 23 steals.
