The Giants badly underperformed at the big league level this year, but the results were far rosier on their farm system.

San Francisco’s Minor League affiliates combined to post the best winning percentage (.577) and run differential (+540) of any organization in the Majors this season, earning Farm System of the Year honors from MLB Pipeline. 

Seventeen players made their MLB debuts with the Giants in 2026, and the youth movement could gain even more steam once the next wave of young talent begins to crest in San Francisco. 

Here are three promising prospects who could have a chance to make an impact in 2027: 

1. Jackson Flora, RHP (Giants’ No. 3 prospect per MLB Pipeline)

The Giants entered the season with a shortage of impact arms in their farm system, but they started to fill that void by selecting Flora with the fourth overall pick of the 2026 MLB Draft.

Flora, the top-ranked pitcher in his Draft class, is already generating buzz, as he struck out 10 and allowed only one hit over five scoreless innings in his first three pro starts in the Minors, two of which came in the playoffs.

Flora, 21, made his first two outings for Single-A San Jose before getting a late promotion to Double-A Richmond, where he struck out four over two perfect innings in Game 2 of the Eastern League playoffs. 

Could that sizzling performance compel the Giants to keep Flora at Double-A Richmond for the start of the 2027 season?

“It might do more than nudge, but I’ve got to be careful,” general manager Zack Minasian said last month. “I don’t want [vice president of player development] Randy Winn to get too mad at me. … I’ll say this for Jackson: He’s put himself in such a great spot with the season ending and what he can be next year.” 

Starting pitching remains a major need for the Giants, who currently have only two hurlers -- Logan Webb and Landen Roupp -- locked into their 2027 rotation. There won’t be much standing in Flora’s way if he continues to dominate, so it wouldn’t be a surprise to see him follow a similar path to Mariners left-hander Kade Anderson, the third overall pick of the 2025 MLB Draft.

Anderson, 22, opened the 2026 season at Double-A Arkansas and started only 18 games there before he was called up to make his Major League debut for Seattle on Aug. 22.

2. Parks Harber, 3B/OF (No. 13) 

One of four players acquired from the Yankees in exchange for Camilo Doval at the 2025 Trade Deadline, Harber looked like one of the Giants’ more intriguing hitters after earning his first invitation to big league camp during Spring Training. Still, he suffered a setback after straining his hamstring while running the bases during a Cactus League game, forcing him to open the 2026 campaign on the injured list. 

After missing the first three weeks of the Minor League season, Harber put himself back on the radar with a strong showing at Double-A Richmond, where he hit .284 with an .879 OPS and 12 home runs over 66 games before earning a promotion to Triple-A Sacramento in mid-July. The 25-year-old continued to put up solid offensive numbers for the River Cats, batting .256 with a .739 OPS and six home runs over 54 games. 

The right-handed-hitting Harber won’t be eligible for the Rule 5 Draft this offseason, so the Giants won’t have much urgency to add him to their 40-man roster next month. But his track record of producing should still put him on the cusp of the Majors heading into next year. A natural third baseman, Harber has started playing the corner outfield to increase his versatility and create more ways for the Giants to get his bat in the lineup in the future.

3. Gavin Kilen, SS/2B (No. 6)

The Giants are loaded with young shortstop prospects, though the first to arrive will likely be Kilen, the club’s 2025 first-round Draft pick. Kilen, who played under manager Tony Vitello at the University of Tennessee, is known for his elite contact skills and batted .286 with an .812 OPS and 11 home runs over 111 games between High-A Eugene and Double-A Richmond in his first full professional season with San Francisco. 

The Giants don’t have an immediate need in the middle infield, as Willy Adames, Casey Schmitt and Marcelo Mayer are all expected to be back in the fold in 2027. But the 22-year-old Kilen could have a chance to break into the big league mix sooner rather than later if he continues to put up big numbers in the Minors.

Three months after being selected by the Giants in the 16th round of the 2026 MLB Draft, third base prospect Dalton Wentz is getting a chance to suit up for the Scottsdale Scorpions in the Arizona Fall League. Read more about Wentz's journey here.
