2026 Kansas City Royals Top Prospects Ranking

Arguably the biggest riser in the Royals' farm system last year, Chourio advanced to three different levels of play in 2025 as a 17-year-old: DSL, Complex, and Low-A. 

At each level, the Venezuelan teenager dominated on the mound. 

In five appearances and 17.2 IP in the DSL, he posted a 2.04 ERA, 0.74 WHIP, 32.8% K rate, and 31.3% K-BB%. In the Arizona Complex League, his dominance continued. In three starts and 11 IP, he posted a 2.45 ERA, 1.09 WHIP, and 35.4% K and K-BB%. As a result of those solid, complex performances, he earned a promotion to Low-A Columbia, despite being younger than most high school seniors. 

Low-A ball was a bit more of a reality check for Chourio. In six starts and 22.2 IP, he posted a 5.16 ERA. However, his WHIP remained solid at 1.06, and his 25% K rate and 20.8% K-BB% were also solid marks, especially for a pitcher of his age. His 3.66 FIP and 3.26 xFIP demonstrated that he was better in Columbia than his high ERA suggested. 

Chourio showcases a plus four-seamer that can touch 97 MPH and an equally plus changeup that plays well off his fastball. His breaking offering needs work, but he still has plenty of time to develop it as he gets more Minor League innings.

Some scouts and insiders have remarked that Chourio shares many comps with Yordano Ventura, the most decorated and successful international pitching prospect developed by the Royals. Granted, that's high praise, and a bit unfair to Chourio, who just turned 18 in October. 

However, the tools, pitch command, and the physical projection (he's six-foot, 160 pounds) are impressive so far with the young Venezuelan. If he continues to develop, he could be the Royals' top pitching prospect by midseason, and perhaps their top prospect by the conclusion of 2026, if everything falls into place. 

In addition to Chourio, the Fireflies had another teenage phenom in Shields, a second-round pick in the 2024 MLB Draft.

After a warm-up start in the Complex League, the Pittsburgh prep prospect made 18 starts in Columbia. In 71.2 IP with the Fireflies, he was flat-out dominant. He posted a 2.01 ERA, 1.02 WHIP, a 28.3% K rate, a 23.1% K-BB%, and 2.57 FIP. These stellar numbers helped him earn Carolina League Pitcher of the Year honors. 

Shields showcased an easy delivery, strong stuff, and excellent command in his tenure with the Fireflies. Here's what MLB Pipeline said about Shields and his pitch repertoire in their latest scouting report:

Quote

Shields was around 93-94 mph with his fastball at instructs in late ‘24, and the Royals expect some more power as he physically matures. The pitch has some deception to it, helped along by Shields’ good extension. His fringe-average breaking ball blends between a slider or curveball depending on who is assessing the pitch, but it typically sits in the low 80s and has the potential to be above average with consistency. Shields has flashed a circle changeup with good armside fade, but that will be a focus for him in his first full year.

The Pennsylvania native doesn't have as electric a velocity as Chourio, but the extension and command have helped him produce more polished results in his Low-A debut. There's also a mature approach by Shields on the mound that may remind some Royals fans of Kris Bubic. However, Shields has more velocity and overall upside than the Royals lefty who made the All-Star Game this past season (primarily because Shields was drafted out of high school, unlike Bubic, who was drafted out of college).

He will likely matriculate to High-A Quad Cities in 2026. He could make a move to Northwest Arkansas by midseason if he dominates Midwest League hitters like he did Carolina League hitters. The swing-and-miss stuff (31.8% CSW) and the strong ability to keep the ball on the ground (46.7% GB%) demonstrate that he can find multiple ways to get batters out, which should help him as he progresses up the Royals farm system.

Gamble was the Royals' first selection in the 2025 MLB Draft, going 23rd overall, five picks before Hammond. The prep prospect was drafted out of IMG Academy, but he grew up in Iowa with an affinity for the Royals.

The 19-year-old doesn't have the raw power or batted-ball upside of Hammond just yet. However, Gamble profiles as a better athlete who not only has blazing speed on the basepaths and gap-to-gap power, but is capable of playing multiple positions in the outfield and infield. 

Looking at his scouting report on MLB Pipeline, it seems the Royals' scouting department valued Gamble's versatility and his ability to grow into his athletic frame as he progressed in the farm system.

Quote

Gamble is a left-handed hitter with a smooth and repeatable swing with a knack for finding the barrel, controlling the zone and doing damage to all fields. As he's gaining strength, he's showing more raw power and should continue to leverage the ball and get to more extra-base authority as he moves along. He had quality at-bats last summer to raise his profile.

A plus runner, Gamble saw a lot of time in center field over the summer of 2024 and looked good there, with some evaluators leaning towards favoring him in the outfield, where his athleticism and arm strength play well. Some don't want to give up on him on the dirt, though, thinking he could be an above-average defender at second base and/or be given a shot at shortstop. The Royals announced Gamble as an outfielder on Draft Day but noted they like his range on the dirt as well, keeping open multiple avenues to him contributing up the middle.

It was tough to discern between Gamble and Hammond as to who is the better prospect in the Royals' system (especially since both have no professional experience). Hammond definitely seems to have more polish now, especially offensively, and it wouldn't be surprising to see Hammond come out of the gate better in Low-A Columbia than his fellow draft classmate. 

However, Gamble has more upside and versatility, with the ability to be an accurate multi-position weapon, which fits what is needed in the modern MLB game. That gives Gamble the edge over Hammond as a prospect, for now.
