Introduction to Giants' Farm System
The San Francisco Giants are positioning themselves for an exciting future, with a wealth of talent blossoming throughout their farm system. This analysis delves into the prospects who are making waves, highlighting the players' potential and timelines. Notably, this is the sixth consecutive year we've specifically categorized relief pitchers into two distinct roles: Multi-Inning Relief Pitchers (MIRP) and Single-Inning Relief Pitchers (SIRP). Each prospect's estimated time of arrival (ETA) offers insights into when they might be added to the 40-man roster to avoid Rule 5 draft eligibility. While we aim for accuracy with these ETAs, adjustments are made based on changing player circumstances.
For those unfamiliar with the concept of Future Value (FV), it serves as an essential metric for evaluating prospects' potential impact. You can find a brief overview of FV [here](https://blogs.fangraphs.com/the-new-fangraphs-scouting-primer/) and a more detailed examination [here](https://www.triumphbooks.com/future-value-products-9781629378800.php?page_id=21).
All prospects mentioned in this review are also featured on “The Board,” a comprehensive resource offering sortable scouting data for every team in baseball.

Rankings of the Top Prospects
Let’s take a closer look at some of the standout players poised to make their marks. They are ranked based on their age, position, highest level played, ETA, and future value, contributing to an overall sense of where they fit within the broader context of the Giants' aspirations. For instance, the first-ranked prospect, Bryce Eldridge, stands at an impressive 6’7” and is already showcasing power and batting skills that could place him among the elite once he fully matures. His rapid ascent through the ranks, including impactful stints at Double- and Triple-A, underscores his readiness to contribute soon.
Each of these young athletes represents a unique blend of skills that could redefine the Giants’ lineup in the coming years. Whether through pitching or hitting, they all bring something important to the table that could significantly shape the team's future trajectory. If you’re following the Giants closely or working in this space, keeping an eye on these prospects could be essential for understanding how the franchise plans to build its competitive edge.Josuar Gonzalez: A Rising Star at Shortstop
At just 18 years old, Josuar Gonzalez is already generating significant buzz in prospect circles. Signed during the 2025 international signing period from the Dominican Republic, he isn’t just another name on a list; he’s considered a potential five-tool player. His performance in the Dominican Summer League speaks volumes: .288/.404/.455 at the plate, while showcasing his defensive capabilities at shortstop with remarkable poise. Gonzalez emerged as the top non-Roki Sasaki prospect in his class, and scouts' enthusiasm remains strong despite some setbacks from hamstring injuries that have limited his visibility.
What stands out about Gonzalez is his explosive nature at the plate, particularly as a switch-hitter. His lefty swing exudes power potential, aided by impressive bat speed. Although his right-handed swing lacks the same coordination, it still packs a punch. His medium frame may restrict his raw power slightly, but the bat speed suggests he could develop into a player with above-average pop as he matures. There’s a minor concern regarding his front-side mechanics, which can drift towards first base, potentially leaving him vulnerable to breaking balls. Yet overall, he demonstrates the ability to hit effectively across the strike zone.
Defensively, Gonzalez checks all the boxes. His quick twitch and strong arm make him a lock at shortstop according to scouts who see elite defensive potential in him. The nagging injuries from this year are a valid cause for concern, especially given that he’s had multiple hamstring strains. This tight-wound athleticism could lead to further issues if not managed well. That said, I am cautious but optimistic about Gonzalez’s long-term prospects. He possesses an enticing combination of skills that could lead to All-Star caliber play if he can maintain his health and refine his hit tool.
Jhonny Level: The It Factor
With the ability to make a significant impact, Jhonny Level stands out in the farm system after absolutely dominating the Dominican Summer League in 2024. Scouts universally recognized him as the top position player in the Arizona complex last year. His impressive performance in the Cal League this spring, where he recorded a 133 wRC+ as the youngest player on the team, further cements his reputation as a player to watch.
Level's game possesses an intangible quality—the “it factor.” His approach at the plate is mature for his age, showcasing the strength to drive the ball while also demonstrating commendable plate discipline. Young hitters often chase pitches recklessly, but Level's discernment at the plate suggests he may continue to develop beyond the numbers.
On defense, he exhibits a proficient arm and quick release, but his fielding skills still require some work. His range is adequate but not exceptional, complicating his path to playing shortstop consistently, especially considering the Giants’ depth at that position. Evaluators speculate he may transition to second base, where he could become an above-average defender.
The key downside for Level is his limited physical projection. He's nearing his physical peak, which raises questions about his future power potential. Some scouts may view him as a good prospect rather than a great one due to these concerns. Nonetheless, Level has a solid offensive profile that makes him a strong candidate for a regular role in the majors.
Luis Hernández: A Top Class Signing
Luis Hernández made waves as the top player in the highly competitive 2026 international signing class, landing a substantial $5 million deal with the Giants. The Giants surprised many by opting to skip the Dominican complex and instead sending him straight to spring training. It turned out to be a wise decision; Hernández has excelled on both sides of the diamond.
Offensively, Hernández is already approaching big league average in raw power, and he's making contact at an impressive rate of over 80%. In just 22 games, he hit five home runs, achieving a remarkable 139 wRC+. His swing is simple yet effective, with an emphasis on maintaining a steady head and avoiding unnecessary movement. He has potential for future growth, and it’s likely he will develop more strength as he matures.
Defensively, Hernández has the skill set to become an elite shortstop. Scouts praise his hands, range, and instincts. His standout performance during San Francisco’s Spring Breakout Game, where he demonstrated his prowess alongside Double-A veterans, left a lasting impression. While there are no guarantees in prospect evaluations, Hernández’s high floor combined with a high ceiling makes him a player to watch closely. He’s set to climb the ranks and could establish himself as one of baseball’s top prospects in due time.
Keyner Martinez: Future of the Rotation
Initially signed for just $10,000 in the 2023 international class, Keyner Martinez has quickly emerged as the most talented arm in the Giants' farm system. Despite facing some developmental challenges in the Cal League, I maintain an optimistic outlook on his future. His profile suggests he could become a reliable mid-rotation starter.
Martinez’s delivery is one of his most appealing aspects. It’s low-effort and balanced, allowing him to generate solid velocity with a mid-to-upper 90s fastball. When he attains his peak, his fastball carries effectively; however, he needs to refine his command further. His slider has the potential to be a plus pitch, with sweeping action and late break. Conversely, his changeup remains a work-in-progress but shows promise in flashes.
One of the lingering issues for Martinez has been his control. In San Jose, he’s walked around 14% of hitters, indicative of growing pains in his development. Despite that, there’s a bright side: he’s also managed to strike out an impressive 37.6% of opponents. These high strikeout numbers may lead to walks as hitters struggle to make contact with his slider, setting up deeper counts. While this inconsistency raises red flags about potential relief risk, the upside is still enticing. A refined approach could elevate him to a consistent presence in a major league rotation. Recognized as a potential breakout player, I’ve moved him into the Top 100.
Carson Whisenhunt: Gaining Momentum
After dominating low-level hitters, Carson Whisenhunt is making a name for himself in the Giants’ organization. While he only made 12 starts across A-ball in previous seasons, this year, he’s been revitalized through the introduction of a new pitch, which has bolstered his chances of sticking in a big league rotation.
Whisenhunt's success largely hinges on his impressive sinker/changeup duo, which faced challenges against more experienced hitters but exhibited effectiveness in striking out batters. He experimented with a cutter this spring, which showed promise but seemed to morph into a more traditional slider during game situations. His mid-90s fastball is powerful, yet it requires more consistency to reach its full potential. The changeup remains a distinguishing factor, with sharp, fading movement that confounds hitters even when overused.
While he’s demonstrated dominance in the PCL, there are questions about his long-term placement. Relying on a high-reward pitch like the changeup may become problematic over longer outings. An intriguing alternative is the potential for Whisenhunt to excel in a bullpen role, much like Devin Williams, where he could maximize his best pitch and become a high-impact reliever. The adaptability in his arsenal leaves considerable room for optimism regarding his development.Closing Insights on the Giants’ Prospects
As we wrap up our analysis of the San Francisco Giants' prospects, it's evident that the team's future may be brighter than it appears at first glance. While the stats and profiles of players like Rodriguez, Harber, Davidson, and Kilen reveal certain limitations, they also highlight their unique strengths and significant potential.
Take Rodriguez, for instance. His versatility—not just as a catcher but across multiple infield and outfield positions—positions him as a valuable asset. His approach at the plate, though perhaps sacrificing some power, showcases an advanced feel for contact that could blossom as he fine-tunes his game. Admittedly, questions linger about his defensive prowess, especially behind the plate. But if the Giants invest in his development as a catcher, they might just unlock a hidden gem.
On the other hand, Harber's unorthodox progression from undrafted player to standout in the minors is remarkable. His offensive metrics tell a compelling story, yet his defensive capabilities at third base are decidedly average, which could limit his ceiling. However, his hitting ability suggests he could emerge as a formidable part-time player on a contending team, highlighting the untraditional routes that can lead to success in today's MLB.
Then there's Davidson, a prospect who’s easily overlooked due to traditional metrics but whose advanced hitting stats merit close consideration. While his physical tools may not scream "star," his ability to perform at the plate is undeniable—albeit with some mechanical concerns that could hamstring his development against elite pitching. If he can adjust to higher levels of competition, he might carve out a solid role, possibly resembling someone like Seth Smith but with added defensive utility.
Lastly, Kilen’s early promise as a first-round pick adds another layer of intrigue. At just 22, the left-handed bat's potential value will be closely linked to his ability to adapt to higher-level pitching. The fundamental skills are there, but how they translate at the major league level remains an open question.
What this boils down to is a blend of opportunity and risk—the hallmark of any prospect-heavy franchise. The Giants might not boast a roster teeming with can't-miss talent just yet, but with careful cultivation and some good fortune, these players could evolve into crucial elements of a competitive team. For fans and analysts alike, that’s a narrative worth following closely in the seasons to come.
