Five Giants Prospects To Watch in Spring Breakout

For years, the San Francisco Giants had as close to a barren system as it got. They’ve repetitively missed on first-round draft picks, and the two names that once dominated prospects boards — Kyle Harrison and Marco Luciano — are no longer with the organization.

Fortunately, times have changed in San Francisco. All of a sudden, there’s a wave of young, exciting talent slowly climbing through the minors and providing real hope for Bay Area fans.

This year’s Spring Breakout is coming up, and the majority of the names poised to make up the next generation of Giants baseball landed on the game’s initial roster. Yes, the Giants’ top prospect, Bryce Eldridge, is likely to compete, but he’s already been playing in virtually every spring training game for the big league club.

Let’s take a peek at some guys who may not be as accessible but should be getting your attention.

1. Luis Hernandez – SS

Hernandez is the newest face to this farm system, but arguably the most exciting. The 17-year-old international prospect signed with the Giants out of Venezuela this January for right around $5 million, which was most of their pool money and the second-highest international signing bonus in the club’s history.

He is believed to be one of the better international prospects we’ve seen in years and is extremely advanced as a hitter for his age.

It’s pretty rare we get a televised, firsthand look at a prospect this raw, especially considering the fact that he’s coming from the international ranks. Typically, these signees spend their first year of affiliated baseball playing in the Dominican Summer League.

Hernandez, however, is going to skip that and immediately make his debut stateside. While it seems a bit crazy because of how young he is, the Giants are confident that he’ll quickly adapt to the talent in America. After all, Hernandez hit .346 in the Venezuelan Major League, where he faced several arms who were formerly in Triple-A or the big leagues at just 15 years old

2. Josuar Gonzalez – SS

Josuar Gonzalez is the consensus second-best prospect in this organization and currently the 58th-ranked prospect in the sport. With a good follow-up to his professional debut in 2025, he could easily jump into the upper echelon of prospects across baseball.

After signing as the best international prospect of the 2025 class, he had an excellent first showing in affiliated baseball. As a 17-year-old in the DSL, he slashed .288/.404/.455 with a 129 wRC+ and more walks (37) than strikeouts (36).

While we’ve already gotten a sneak peek at Gonzalez in the Cactus League this year — where he has two hits in just four at-bats — it’s always fun to get an up-close look at a prospect with this kind of potential so early in his development.

Expected to stick at shortstop, the now 18-year-old is looking to be a big part of what the Giants are doing in a few years. Once Bryce Eldridge graduates this season, Gonzalez should be the consensus top prospect in the organization.

3. Jacob Bresnahan – LHP

Bresnahan skyrocketed up the organization’s prospect list this year after a breakout 2025 campaign. At just 20 years old, the southpaw dominated Single-A, earning the California League’s Pitcher of the Year Award.

In 22 starts and 93.0 innings, he held a 2.61 ERA and 3.00 FIP. He struck out 32.5% of the hitters he faced while only giving up two home runs through the entirety of the season. While Bresnahan’s fastball isn’t anything special in terms of velocity (low-to-mid 90s), he gets a lot of extension with some serious IVB, which helps it miss bats.

When acquired from the Guardians in a deal for Alex Cobb, he had thrown just 50 innings in professional baseball. The Giants clearly had an eye on the former high school draft pick for a while, and he now profiles as the club’s top pitching prospect.

4. Gavin Kilen – INF

Kilen was the Giants’ first-round draft selection last summer, taken as the 13th overall pick. Funny enough, he had just finished his junior year playing for Tony Vitello at the University of Tennessee — the same Tony Vitello who’s now the manager of the Giants.

It was that final collegiate season that really pushed his name into the first-round conversation. He had a 1.112 OPS while slashing .357/.441/.671 in 245 plate appearances. Striking out just 11% of the time, Kilen also avoided punching out, which is a feat the new regime in San Francisco has been very clear about liking.

While he did struggle in his first taste of pro ball, Kilen’s profile could allow him to climb through the ranks extremely quickly. With there currently being a long-term opening at second base for San Francisco, he’s definitely a guy to watch in the Spring Breakout and through the next year.

5. Trevor Cohen – OF

Similar to Kilen, Cohen is the exact profile of hitter that Buster Posey and Zack Minasian appear to be drawn to. In 2025 at Rutgers, he was simply one of the best pure hitters in the country.

With a .387 batting average and .460 on-base percentage, he was a tough out every time he stepped into the box. While he only launched two home runs, he swiped 19 bases and struck out just 5.5% of the time.

He may not offer the elite upside that some of these prospects do, but his floor is extremely high. Because of the ability to put together good at-bats and avoid striking out, he could be a fairly quick riser through the system.
