SF Giants Low-A affiliate should have an intriguing group of prospects in the rotation in 2026

SF Giants Low-A affiliate, the San Jose Giants, will look to repeat as California League champions in 2026. They should have an intriguing group of pitching prospects, headlined by Argenis Cayama, Keyner Martinez, and Luis De La Torre.

SF Giants Low-A affiliate should have an intriguing group of prospects in the rotation in 2026

San Jose dominated the California League in 2025. They finished with an 81-51 record while sweeping the Inland Empire 66ers in two games in the Championship Series. It marked their first championship since 2021.

The Giants Low-A affiliate excelled on both sides of the ball. The lineup averaged 6.14 runs per game while posting a .755 OPS, which was first and second in the league, respectively. That unit was led by Robert Hipwell, Dakota Jordan, Jean Carlos Sio, and Jakob Christian. Sio and Christian earned mid-season promotions.

San Jose’s pitching staff comfortably led the league with a 3.50 ERA. The Visalia Rawhide were second in that category with a 4.31 ERA. Jacob Bresnahan, Hunter Dryden, and Niko Mazza were some of the top arms in San Jose’s pitching staff.

That roster should experience a good bit of turnover. Argenis Cayama, Keyner Martinez, and Luis De La Torre finished the year with San Jose, but are a good bet to return in 2026.

It is probably too early to be talking about the minor league rosters, but the offseason has been unusually quiet. That could pick up steam once the calendar turns to January.

Cayama, Martinez, and De La Torre anchored the Arizona Complex League Giants rotation before earning a promotion to San Jose once that season concluded.

Cayama and Martinez have catapulted up the Giants’ prospect rankings, appearing at No. 9 and No. 10, respectively, per MLB Pipeline. De La Torre currently sits at No. 25.

In the ACL, Cayama pitched to a 2.25 ERA with 55 strikeouts and 18 walks in 48 innings. He made six appearances for San Jose. Martinez recorded a 1.90 ERA with 67 strikeouts and 10 walks in 47.1 innings for the ACL Giants. He also made six appearances for San Jose. Both pitchers are on the younger side, but have a relatively advanced feel for pitching.

On the other hand, De La Torre tallied a 3.72 ERA in 38.2 innings in the ACL. He thrived in his brief stint with San Jose, recording a 1.77 ERA with 47 strikeouts and 11 walks in 35.2 innings. He turned 22 in September, and the Giants might be a little more aggressive with his development next season. If all three prospects begin next season in San Jose, that should be a fun rotation to follow.
