It’s become a punchline. The Cleveland Guardians just can’t hit homers. In 2023, the Guardians compiled just 124 round-trippers, last in MLB by a wide margin. A key culprit for this power outage has been the outfield and DH spots, where teams typically stow their premium sluggers. Guardians outfielders amazing hit only 18 HRs in 2023, good for a measly 84 wRC+, while the DH spot was accumulated 21 homers and an 81 wRC+. Given the Guardians’ proclaimed budget constraints and history of meager spending in free agency, it is reasonable to assume that large improvements to their power-hitting woes in 2023 will have to come from prospects. A common method for evaluating prospects is the use of “comps”: past or current MLB players that are similar to the given prospect. This article will use AAA metrics to provide comps and evaluate the strengths and weaknesses of four Guardians AAA prospects: Kyle Manzardo, George Valera, Johnathan Rodriguez, and Jhonkensy Noel.
To evaluate the profile of each hitter, I chose metrics that covered multiple facets of hitting. These facets include plate discipline, contact ability, contact type, hard contact consistency, top-end power, and actualized power. Here is a summary of the metrics used:
Most of these 13 metrics are fairly well-known and commonly used when evaluating players. Here is an explanation of Best Speed for the uninitiated. I specifically selected metrics that are “process-driven” and not affected by results to keep comparisons context-neutral of stadium and other factors.
Taking inspiration from the ZiPS projection system, I used Mahalanobis distance to generate comparable hitters in these 13 metrics. Simply put, the idea of using Mahalanobis distance in this case is to evaluate how similar the metrics of two players are, while taking into account that some metrics are related to each other. So, if players have both similar average EVs and hard-hit rates, it will not “double-count” their similarity to the extent of which both of those statistics are correlated. Mahalanobis distance is used in a similar fashion to find MLB player comps here. To keep the hitter comps fresh and recent, the 4 AAA prospects were compared to MLB individual player seasons from 2021–2023. Keep in mind that these player comps are: 1) Only as hitters, not factoring in fielding ability, baserunning, or body type. 2) Comparisons between AAA and MLB metrics. Obviously, maintaining the same metrics in the majors is a much tougher task. 3) Comparisons made to individual MLB player seasons, not careers. While many of these metrics are stable from season to season, this is a key distinction. 2023 Miguel Cabrera is not the same as career Miguel Cabrera. With all that said, here is an evaluation of all 4 Guardians prospects…
Kyle Manzardo
Manzardo, acquired from the Rays at the trade deadline for Aaron Civale, is widely regarded as a Top 100 prospect. Drafted in 2021, he followed up a scorching 2022 season with a 2023 campaign interrupted by a nagging shoulder injury. Despite a slight drop in production, Manzardo’s 2023 metrics were still quite impressive:
(Percentile is for 2021–2023 MLB 300+ PA batters)
Manzardo was above average in essentially all facets of hitting in 2023 (Percentiles are displayed as more = better for all statistics other than Whiff% and Chase%, though percentiles aren’t as relevant for Swing% and Avg Launch Angle). He especially excelled at controlling the zone and making contact, while displaying slightly above average raw power. As such, many of his comps are also similar to this profile:
That’s quite the list of hitters! Like Manzardo, his comps are excellent hitters who overperform their raw power by making consistent, hard and elevated contact. If Manzardo can repeat the power display he showed in the Arizona Fall League, he seems like a safe bet to be a contributor to the 2024 Guardians at both 1B and DH.
George Valera
Valera is a Guardians top OF prospect that was slowed by hand injuries in 2023, which both limited his playing time and seemed to affect his level of play, as he posted a mediocre statline in AAA. Valera’s injury history combined with concerns about his somewhat grooved swing have resulted in a cooling of his stock entering 2024. However, he is still just 23 years of age and tremendously talented. Here are his 2023 metrics:
(Percentile is for 2021–2023 MLB 300+ PA batters)
Valera is a player that fits the classic archetype of power + plate discipline with below average contact skills. While he does not have the typical high-end EVs of a slugger, Valera makes consistent hard contact while not chasing much at all, with an overall approach that leans towards passive. However, he has serious issues with making contact both inside and outside the strike zone. Here are Valera’s comps:
I think it’s fair to say that Valera is quite similar as a hitter to Andrew McCutchen (of recent vintage)! McCutchen also possesses elite plate discipline and power numbers greater than his raw power would suggest. However, McCutchen’s contact skills are better than Valera’s. In sum, Valera’s metrics and comps based on his 2023 seasons are (unsurprisingly) less impressive than Manzardo’s. However, he still may either improve on them in a healthy 2024 or embrace a role as a high OBP + low AVG hitter, which could work when combined with his solid range and plus arm in the OF.
Johnathan Rodriguez
Rodriguez was perhaps the most positive surprise amongst Guardians prospects in 2023, as he mashed 29 home runs between AA and AAA. Rodriguez is a late-bloomer as a 2017 high school selection, though he’s always had massive raw power. J-Rod’s boom or bust approach is exemplified in his limited (202 PA) AAA metrics:
(Percentile is for 2021–2023 MLB 300+ PA batters)
Rodriguez is the classic all-or-nothing masher. While his average LA is quite low, when he does hit the ball in the air, they go a long way. J-Rod is excellent at squaring balls up for maximum damage, letting his above average raw power play up. However, his plate discipline and contact skills leave a lot to be desired. He does have a penchant for chasing, but the biggest questions are with his contact ability, particularly against fastballs. J-Rod posted a 33% whiff rate vs the pitch in AAA, which is a major red flag for how he projects vs MLB pitching. However, his player comps are impressive:
Unlike with Manzardo and Valera, I don’t feel that J-Rod’s comps properly mirror his strengths and weaknesses. They tend to emphasize the power aspect of his game, in which he is similar to all the players listed above. However, his comps all have lower Whiff rates than Rodriguez, some (like Seager), significantly so. I think this is because J-Rod’s raw contact skills (in terms of Z and O Contact individually) aren’t horrendous and are comparable to players like the Contreras brothers on this list. However, when combined with a high Chase%, they result in an unsustainably high Whiff%. If Rodriguez can refine his approach some, he could be a real impact bat.
Jhonkensy Noel
Noel is perhaps the most puzzling player of the 4. A physical speciman, Noel is capable of unloading on a homer, which he had 27 of in 2023. However, many of his AAA metrics don’t read like those of a huge power hitter:
(Percentile is for 2021–2023 MLB 300+ PA batters)
While Noel has an elite Max EV, unlike Rodriguez he has trouble consistently making hard contact. Noel has an aggressive approach that includes chasing pitches out of the zone at a very high rate. Because of this and a likely supbar ability to square up the baseball, Noel is often wrong-footed on his swing, leading to either harmless popups or dribblers. As a result, Noel has a supbar Hard-Hit rate and just a meh Barrel%. While Noel struggles to hit all pitches hard, he whiffs and chases a disproportionate amount of the time against breaking pitches:
Due to this very strange profile, the “comp machine” has a very hard time finding a match for Noel. His most comparable player-season was of a similar “distance” to the 7th-8th most comparable player of the other three prospects. Here are Noel’s top comps:
Not exactly the list of sluggers that one might expect at first thought. Perhaps most interesting is Maikel Franco, another player with excellent (though not quite as elite) high-end EVs who failed to make the most of his power potential. Many of the others comps are middle-infielders or utility players. These comps are of course inaccurate, but the fact is that in the view of almost every metric, Noel isn’t an elite power hitter or particularly strikeout-prone. While he did hit 27 HRs in the AAA season, the 2023 hitting environment at the AAA level combined with Columbus’s small ballpark makes this number less remarkable (Of 23 players with 550+ PA in AAA this season, 12 had >20 HR). Furthermore, Noel had very few other extra-base hits on the season (just 23 2Bs and 0 3Bs). Noel is a very unique prospect that resists comparison with recent MLB players.
In sum, the Guardians have a number of intriguing power-hitting prospects at the AAA level. Kyle Manzardo is an excellent hitter who compares favorably with many of the recent top all-around hitters at the major league level. George Valera is the classic OBP + HR hitter that will need some improvement (including on the health front) to become a star. Johnathan Rodriguez has many of the attributes of top MLB sluggers, but improving his approach will be key to success. Jhonkensy Noel is a puzzling and unique player. He will need to fine-tune his swing and breaking ball recognition to be an impact bat in MLB.
