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.

Let’s see who else merits a look.

Five Big Hype Prospects

James Triantos, 20, 2B/3B, CHC
(A+/AA) 363 PA, 4 HR, 16 SB, .287/.364/.391

Triantos spent much of the 2023 campaign in High-A. My contacts have long liked the 2020 draftee as a breakout candidate, but his in-game power output remains below expectations. There’s late bloomer talk as a result. Bear in mind, we’ve grown a bit spoiled with precocious players who aren’t yet of legal drinking age. On the defensive side, there’s are concerns he won’t stick at second base. His bat might not work in a corner role. Triantos has a 1.230 OPS in 16 AFL plate appearances.

Ricky Tiedemann, 21, P, TOR
(CPX/A/AA/AAA) 44 IP, 16.77 K/9, 4.70 BB/9, 3.68 ERA

One of the top prospects in the AFL, Tiedemann is drawing extra work after managing only 44 regular season innings. Those regular season frames were among the best in the Jays system – he led their entire farm in several ERA estimators. The bulk of the action came in Double-A where a high walk rate, BABIP, and low left on base rate led to a 5.06 ERA. Tiedemann is a candidate to make the 2024 Blue Jays, but it’s also likely he’ll have his workload carefully managed. Role: tbd. Through one AFL start, he worked five innings and allowed one run on three hits and three walks with seven strikeouts.

Tekoah Roby, 22, SP, STL
(AA) 58.1 IP, 10.6 K/9, 2.3 BB/9, 4.94 ERA

Like Tiedemann, Roby is getting extra work in the AFL due to missed time during the regular season. After being traded at the deadline, the right-hander pitched impressively in four starts for the Cardinals. His AFL outing consisted of three shutout innings. He allowed one hit with five strikeouts. He features a repertoire of four above-average pitches led by an excellent curveball. FanGraphs drops a Hunter Brown comp. Personally, I smell a whiff of Aaron Nola. He’s trending high floor, high ceiling as a prospect.

Notably, the Cardinals have struggled to finish their pitching prospects. Their matriculated pitchers like Zack Thompson and Matthew Liberatore often show little understanding of pitch design. Even Johan Oviedo took an instant step forward upon leaving the Cardinals. It’s unclear if this is a persistent organizational failure or pure happenstance.

Max Muncy, 21, SS, OAK
(A+/AA) 545 PA, 10 HR, 13 SB, .275/.353/.411

While most facets of his game remain a work in progress, Muncy appears to be trending toward some form of big league future. The 2021 first-rounder made considerable strides with his contact rate during the 2023 campaign. Scouts mostly view him as a utility guy in the making, although there’s still plenty of time for him to develop the game power and defensive consistency necessary to serve as a regular. His AFL season is off to a splashy start with a 1.009 OPS in 18 plate appearances.

Graham Pauley, 23, 3B, SD (AA)
(A/A+/AA) 551 PA, 23 HR, 22 SB, .308/.393/.538

Since their minor league affiliates skew hitter-friendly, the Padres have a knack for producing exciting-looking position players who fade on the approach run to the Majors. Success stories like Ty France tend to be the exception rather than the rule. Pauley didn’t have much of a draft pedigree when he was selected in 2022, but he’s since developed a reputation as a guy who gets the job done despite unconventional hitting mechanics. A left-handed hitting corner fielder with an extreme pull approach, he might reach the Majors as a carefully managed platoon man – the kind of player favored by teams like the Brewers, Rays, and Giants.

Three More

Adam Seminaris, MIL (24): Acquired in the Hunter Renfroe trade, Seminaris is Rule 5 eligible this offseason. He’s playing for a roster spot in Milwaukee or elsewhere. The soft-tossing southpaw is off to a good start in the AFL. He worked four scoreless innings with one hit and seven strikeouts.

Jackson Jobe, DET (21): One of the fastest-rising pitching prospects, Jobe is rounding out a season that saw him throw about 20 fewer innings than 2022. Since Jobe could be a midseason consideration for the Tigers, his workload is of obvious concern. His AFL debut consisted of four shutout innings with two hits, two walks, and four strikeouts.

Chase DeLauter, CLE (22): DeLauter is the current AFL RBI leader. Like many a Guardians outfield prospect, DeLauter rarely whiffs. His awkward-looking swing has no analogs in the Majors. It looks a bit like a stumbling-drunk Alek Thomas. While credited with plus raw power, it’s unclear if his bat will play against stiffer competition.

Five Big Hype Prospects

Kyle Manzardo, 23, 1B, CLE (AAA)
313 PA, 11 HR, 1 SB, .238/.342/.442

Manzardo burst onto Top 100 prospect rankings last season with a flashy 22-homer performance in nearly 400 plate appearances split between High- and Double-A. He has all the traits armchair prospect analysts (like myself) crave – plus discipline, a high rate of contact, and above-average exit velocities. If there was a fly in the ointment, his combination of high BABIPs and frequent fly balls seemed untenable. This season, he’s dropped to a more plausible .269 BABIP while maintaining the fly ball rate. His 2023 numbers more closely match his identity. His power outcomes have backed up, but there’s little cause for long-term concern. Additionally, Progressive Field is friendly to left-handed power hitters. Manzardo is undersized for a first baseman, and his power draws 45 and 50 grades on the 20/80 scouting scale. The profile reads a lot like a four-inches-shorter, left-handed Rhys Hoskins.

Luisangel Acuna, 21, 2B/SS, NYM (AA)
402 PA, 7 HR, 42 SB, .315/.377/.452

Repeating Double-A after a rough first exposure last season, Acuna has looked comfortable at the level. His BABIP-fueled batting line is 21 percent above league average (121 wRC+) despite middling power numbers. Like his brother, Luisangel has terrorized opponents on the basepaths. Scouts rate him as merely an above-average runner. There is a degree of swing-and-miss (12.4% SwStr%) to Acuna’s game that calls his future role into question. He’s expected to grow into average or better power if he can learn to lift the ball more consistently. Whether or not he can do so without developing a strikeout problem could depend on the sort of adjustment required. Lift-related mechanical changes tend to exacerbate whiff issues. In some cases, the issue is the location of contact – an adjustment that can yield positive results without negative repercussions. Acuna’s swing is violent and loud. Change could prove challenging. Despite strong walk rates, Acuna is an aggressive swinger, particularly at breaking balls below the zone.

Necessary offensive adjustments aside, there’s also question about Acuna’s future defensive role. He’s a physically capable shortstop who yet lacks polish. Lately, we’ve grown accustomed to seeing shortstop prospects with precocious defensive ability. Acuna could be asked to move over to second or third to better accommodate his ascent alongside Francisco Lindor.

Marco Luciano, 21, SS, SFG (MLB)
(AA) 242 PA, 11 HR, 6 SB, .228/.339/.450

The only member of today’s column who wasn’t traded, the Giants rushed Luciano to the Majors to cover a short-term opening at shortstop. Despite tepid overall numbers at Double-A, Luciano caught a heater beginning in late June. He batted .315/.397/.500 over his final 63 plate appearances at the level. His success carried over to a 27-plate appearance stint in Triple-A where he batted .292/.370/.625 with Major League caliber exit velocities. He’s 3-for-11 with five strikeouts thus far in the Majors. The once uber-prospect has developed into a slug-over-contact future third baseman. His strikeout rate might check in north of 30 percent. Only 11 qualified hitters have strikeout rates above 30 percent. The good news is nine of 11 have above-average batting lines. The two who don’t – Teoscar Hernandez and Byron Buxton – are celebrated hitters. Luciano will look to join this cohort of hitters.

It’s unlikely Luciano sticks with the contending Giants in the short term.

Edgar Quero, 20, C, CWS (AA)
321 PA, 3 HR, 1 SB, .246/.386/.332

A switch-hitter, Quero emerged as a bat-first catching prospect last season when he hit .312/.435/.530 with 17 home runs and 12 stolen bases in 515 Low-A plate appearances. The Angels made the curious decision to skip him past High-A – perhaps seeking to pair him with a better defensive instructor. His discipline remained in evidence this season. The power… not so much. Another plausible explanation of Quero’s aggressive assignment is to see if he merited moving to a different position to accommodate his bat. Instead, the Angels moved him from the organization entirely in the Lucas Giolito trade. Look for Chicago to slow the roll on Quero’s development. His defensive skills are reported to remain relatively raw.

Thomas Saggese, 21, 3B, STL (AA)
418 PA, 15 HR, 8 SB, .313/.379/.512

Saggese doesn’t have the physical traits evaluators crave, but he makes up for it with a hard-nosed playstyle. Part of the Jordan Montgomery trade, it feels like he was always destined to join the Cardinals. His tools draw a collection of 40 and 50 grades, but his feel for quality contact allows the total package to play up. Multiple reports reference his success against sliders. Something to watch is how he performs against upper-level pitchers with big fastballs and command. The Cardinals might seek to add corner outfield to Saggese’s bag of tricks. He fits best at third base, is considered too short for first base, and just passes at second base. The Cards love their role players to possess a deep well of utility.

Three More

Tekoah Roby, STL (21): The prospect headliner of the Montgomery trade, Roby has a four-pitch repertoire of above-average offerings. His best weapon is a double-plus curve ball. He’s currently sidelined with a shoulder injury. There’s relief risk for health reasons only – the stuff and command are sufficient to project a mid-rotation role.

Marco Vargas, NYM (18): Stolen from the Marlins in the David Robertson trade, Vargas is one of the flashier talents in the complex. He’s batting .283/.457/.442 with nearly twice as many walks as strikeouts and a strong rate of contact. Power development will decide whether he’s viewed as a future utility fielder or core performer.

Adam Kloffenstein, STL (22): Part of the return for Jordan Hicks, Kloffenstein is a big right-hander with a limited repertoire. He tunnels a sinker and slider in a way reminiscent of Brady Singer and Brad Keller. He has a solid feel for command and projects to eat innings in an uninspiring way. He’s pitched to a 3.24 ERA in 89 Double-A frames.
