Aside from competing with the juggernaut Dodgers right now, part of the challenge that Buster Posey has and will face with the Giants is rebuilding a farm system that hasn’t given much in the way of homegrown talent. Heading into 2026, the Giants’ system includes some big lottery ticket prospects, plus a hulking slugger, among others.
San Jose Giants
In terms of potential, the San Jose Giants were the team that held many of who could be considered the best prospects in the team’s system. Cam Maldonado, Lorenzo Meola, and contact machine Trevor Cohen make their debuts with San Jose. Also, there were some other notable hitters in Low-A for the Giants.
We’ll start with Maui Ahuna and Walker Martin, two of the Giants’ top draft picks in recent years. Martin was San Francisco’s second-round pick from 2023, while Ahuna was a fourth-rounder from 2024.
Ahuna missed a healthy chunk of 2025 due to injury. High Whiff% (35.7%) but also had 15 extra-base hits in 37 games, as well as a BB% above 10%. He was promoted to High-A in July.
Martin, though, wasn’t as productive. He did hit 12 home runs and 13 stolen bases. But on the other hand, his 34.8% Whiff% over a much larger sample size is indicative of the issues Martin has dealt with as a pro.
Infielder Jhonny Level, an 18-year-old who moved to San Jose after a strong year in the ACL, made consistent contact (24% Whiff%) with the baby Giants.
Lastly, Dakota Jordan (29.5% Whiff%) was an explosive player at MSU. He showed that in San Jose, as he hit .311 (.874 OPS) with 14 home runs and 27 stolen bases.
As for the pitching staff, the gem was Jacob Bresnahan, whom the Giants acquired in July 2024 for pitcher Alex Cobb. His 35.8% Whiff% was among the 10 best in the California League last season.
Despite being one of the lowest groundball pitchers in the circuit, Bresnahan gave up just two home runs over 93 innings.
Eugene Emeralds
The stars of the Emeralds’ 2025 team were the bats. More specifically, James Tibbs and Bo Davidson.
Tibbs was the Giants’ 2024 first-round pick, taken after a standout collegiate career with Florida State. A very disciplined player with a high take (58.3%) and walked quite a bit in High-A, Tibbs slashed .246/.379/.478 with 12 home runs and 23 extra-base hits across 57 games. Also, plenty of contact (24.7% Whiff%).
It was a strong, yet brief run for Tibbs in Eugene. However, his time in the Giants’ organization didn’t last long. The Giants traded Tibbs, along with three others, to Boston as part of the Rafael Devers trade in June.
Bo Davidson, an undrafted free agent find by the organization, had a fantastic run in Eugene. Davidson was an extra-base machine for the Emeralds, as he had 30 extra-base hits in his time with Eugene. Additionally, the outfielder added 12 stolen bases.
Davidson didn’t have a high take rate, yet was able to walk 49 times over 72 games. Also, not that much swing-and-miss.
Parks Harber, who hit very well in the Yankees’ farm system before he was part of the Camilo Doval trade, slashed .333/.454/.644 with seven home runs and 13 extra-base hits across 25 games after the deal.
As for the pitching staff, Josh Bostick (28% Whiff%) had himself a very good year. Bostick, an over-the-top pitcher, struck out 139 over 119 innings. Running fastball but Bostick gave up a lot of well-hit contact. The righty gave up 21 home runs in the Northwest League.
Unsurprisingly, his batted-ball lean was towards fly-balls. His 31.9% FB% was among the 20 highest in the circuit.
Richmond Flying Squirrels
Richmond’s roster included several longtime Minor Leaguers, including Turner Hill and ex-Pirate Cal Mitchell. The team leader in home runs was Victor Bericoto, a former 27-home run hitter who spent his third season with the Flying Squirrels last season.
Bo Davidson and Bryce Eldridge, the latter of whom was the Giants’ first-round pick, were the two big hitters on the Flying Squirrels this past year.
Davidson handled Double-A fine, despite the .234 batting average. A sub-30% Whiff%, eight home runs, and a 36.6% FB% that ranked among the top-11 among Eastern League hitters (min. 100 batted balls).
As for Eldridge, the towering power hitter was very aggressive in the Eastern League, as he swung at pitches over 50% in the league. While there was swing-and-miss, he hit for power in Double-A, with seven home runs and 15 total extra-base hits before he moved up to Triple-A.
Sabin Ceballos, who ranked among the top-20 in the league in take percentage (59.3%), walked 47 times and struck out just 73 times over 108 games. However, Ceballos, a former third-round pick by Atlanta two years ago, posted a .106 ISO in Richmond.
Richmond’s pitching staff was highlighted by left-hander Joe Whitman, who enters 2026 as arguably one of the Giants’ 10 best overall prospects. The 24-year-old Whitman, a former second-round pick, struck out 124 over 117 innings.
Whitman is a deceptive lefty, and one with an arsenal that should work in a starting role. A low-to-mid-90s four-seamer and sinker, coupled with a changeup that had about an eight to 10 MPH separation off the fastball, and a slider.
Low groundball pitcher in Double-A, as his 39.2% GB% ranked below the Eastern League median. Additionally, Whitman isn’t a high swing-and-miss pitcher (24.7% Whiff%), which does complicate his future value.
The big swing-and-miss pitcher on Richmond’s roster was Will Bednar, the Giants’ 2021 first-round pick. Now a reliever, Bednar (35.3% Whiff%) struck out 84 over 52.1 IP. On the other hand, Bednar walked 39 batters in yet another year where he had to fight the walk problem. The right-hander surrendered 36 over 32.2 IP with Richmond the year before.
Sacramento River Cats
The River Cats’ 2025 roster included plenty of ex-Major Leaguers, including former Rays infielder Osleivis Basabe, Sam Huff, plus Grant McCray and, at one point, 2024 breakout star Tyler Fitzgerald.
As far as the offense was concerned, perhaps the two most interesting names in Sacramento were Marco Luciano and, later on, Bryce Eldridge.
Luciano, once a top prospect in the Giants’ system, hit a team-high 23 home runs for Sacramento. However, he struck out 170 times over 125 contests, illustrating a long-standing problem for him.
For Luciano, the problem hasn’t been expanding out of the zone. The now-former Giants prospect expanded at a rate of 20.7%, well above the Triple-A median last season. However, for a player like Luciano, who has plenty of power and bat speed, it’s all about whether he can make enough contact on those pitches inside the zone, especially the non-fastballs, which gave him fits in his brief MLB stints.
This past year, Luciano had a 27.1% in-zone Whiff%, which ranked him in the bottom-20 of all Triple-A hitters.
Eldridge, like Luciano, ranked in the bottom-10 of the Pacific Coast League in Whiff% (although the former’s problems were far fewer than Luciano’s). However, his in-zone Whiff% (20.1%) was lower, and the young first baseman hit well enough to earn his first look at MLB pitching this past September.
The 21-year-old hit 18 home runs and 31 extra-base hits over 66 games.
Moving to the pitching staff, the River Cats had a fascinating group of pitchers.
Trevor McDonald, who pitched very well in late September for the Giants, had one of the highest swing-and-miss rates in the PCL last season. The same can be said for Kai-Wei Teng, who didn’t have as much success when the Giants called his number in the summer.
Carson Whisenhunt had a puzzling year, as the left-hander — who worked with a running fastball, changeup, and slider in Triple-A — didn’t miss nearly the same amount of bats he did a year before with Sacramento.
Carson Seymour (25.3% Whiff%) wasn’t missing that many bats, either. However, he struck out 90 over 77 innings and induced a lot of groundballs, a key to success in a hitter-friendly circuit.
Hayden Birdsong, who had a problem with walks with the big club, walked 30 over 39 innings for the River Cats.
Early Projected Top 5 for 2026
- Bryce Eldridge
- Gavin Kilen
- Bo Davidson
- Josuar Gonzalez
- Jacob Bresnahan
As far as some of their peers in the National League, the Giants don’t have as deep a Minor League system. Part of that has been because some of their past MLB Draft picks have not developed as hoped.
Aside from Walker Martin’s struggles, the Giants have received no MLB production from former first-rounder Reggie Crawford, who’s been injured for most of his professional career.
The Giants, assuming the team holds on to Eldridge, will need their top prospect to become an impact hitter. Aside from Eldridge, the team does have notable talent. However, some of these players are years away from being potential assets at the Major League level.
Like Gonzalez, one of the crown jewels from the 2025-26 international signing period.
