No. 7: Humberto Cruz (Low-A, Lake Elsinore Storm)

Humberto Cruz was frequently linked to the San Diego Padres during the build up to his international free agent class, but then the Friars blew $4.2 million on Leo De Vries. In order to facilitate a Cruz signing, the front office traded Blake Dickerson to the Tigers for international signing money, convincing the teenage right-hander out of Mexico to join the organization on a $750,000 signing bonus.

Since then, Cruz hasn’t pitched much for the Padres. He made two truncated appearances in the Arizona Complex League in 2024 and opened the 2025 campaign at the same level. Though the results were far from pretty (8.31 ERA, 6.57 FIP), the Padres pushed him up to Low-A Lake Elsinore. He made 14 total starts covering 38 innings across both stops, but Cruz’s season ended prematurely when he went down in mid-August with an elbow injury. It later required an internal brace procedure, knocking him out potentially for all of 2026.

That surgery, in conjunction with his poor results last year — 7.58 ERA, 6.78 FIP, 20.5% strikeout rate, 9.9% walk rate — paints a grim picture for the 19-year-old. However, his raw talent remains tantalizing, and he’s got a lot of time on his side. Last measured at 6’1″, 170 pounds, Cruz is stilling filling out his lanky frame. He’ll certainly put on more bulk throughout his rehab process, lending hope that he’l eventually have the build to withstand a starter’s workload over a full season.

Cruz’s fastball is viewed as run of the mill at the moment, possessing mid-90s velocity with an average amount of run. A little more spin and two-seam action would help it play up better in the zone, as would another jump in velocity upon his return from injury. His best pitch is undoubtedly his slider, which has a lot of vertical brake and is much closer to a slurve than a sweeper. That pitch generated a 58% whiff rate in Low-A last year, which suggests even the 55-grade it has received may be a bit outdated. If he can elevate his fastball more frequently, Cruz could find himself in a situation where he simply abuses even the best hitters down in the zone with his slider.

He accentuates his arsenal with a fading changeup designed to get lefties out, which has shown good shape but inconsistent location. It’ll be a key developmental piece for him down the road — with three above-average offerings, Cruz can remain in the rotation. Otherwise, his fastball-slider combo will function nicely in a high-leverage bullpen role.

Expected to miss most, if not all, of the 2026 season as he rehabs his elbow, Cruz’s timeline has taken a hit since the start of last year. The potential to become a mid-rotation starter remains, but he’ll need to prove healthy and capable of ascending quickly if he hopes to remain on the top-prospect radar in the future. However, seeing as he won’t turn 20 until December, the Padres have no incentive to rush him back.
