2026 Fantasy Outlook
Pitching prospects will break your heart, but Chourio is as fun to dream on as any lower-level pitching prospect. He signed for less than $300K out of Venezuela and was sent to the Dominican Summer League as a completely under-the-radar 17-year-old. Chourio laid waste to the DSL (31.3 K-BB%) and then the Arizona Complex League (35.4 K-BB%) before getting another aggressive assignment with a bump to Single-A Columbia on July 29. He logged an unlucky 5.16 ERA to go with a 1.06 WHIP and 24:4 K:BB in 22.2 innings across six starts at Single-A and tallied 51.1 innings across three levels. It's incredibly rare for a 17-year-old pitcher to follow that path in their first pro season. Chourio already boasts a 95-98 mph fastball and two strong secondaries in his curveball and changeup. His changeup is already one of the best changeups among minor-league righties. His combination of stuff, command and polish give Chourio one of the highest ceilings among all pitching prospects. He could reach the majors at 19 or 20 if he stays healthy. Read Past Outlooks
Signed a contract with the Royals in January of 2025.
Living up to expectations
Chourio has a 1.42 ERA, 0.71 WHIP and 15:2 K:BB in 12.2 innings through three starts for Single-A Columbia.
Analysis
Despite the fact Chourio won't turn 19 until October, his assignment to Single-A was hardly surprising, as he had a 20.8 K-BB% and 1.06 WHIP in six starts for the Fireflies to close 2025. Chourio has an enviable combination of easy mid-90s fastball velocity, plus command and several high-quality secondary pitches. He, along with Seth Hernandez of the Pirates, leads an enticing group of lower-level arms that will vie for the title of No. 1 pitching prospect in baseball in 2027.
