Follow the Prospects: Riley "The Great" Cornelio, RHP
« on: August 06, 2025, 01:14:10 pm »
Born: 6/06/2000 in Honolulu, HI
Draft: 2022, Washington Nationals, Round: 7, Overall Pick: 201
College: Texas Christian
6'3", 195lbs

Stats: https://www.milb.com/player/riley-cornelio-683000

Was touted as a possible top draft pick in 2019 but ended up attending TCU

Fangraphs #36 prospect at time of this posting:

Quote
Fastball   Slider   Changeup      Command    Sits/Tops
40/45      70/70.      40/45      30/35           93-96 / 97

Cornelio was a famous high school prospect thanks to his prototypical build and mid-90s fastball, but he ended up at TCU, where he barely pitched until his junior year. As a pro, Cornelio has reached Double-A as a starter but projects into a big league role as a reliever due to a lack of fastball playability and command. He’s sitting 94 and touching 96-97 pretty regularly early in starts, but he’s only missing bats with his fastball half as often as the big league average because that pitch lacks effective movement. In the bullpen, where he might sit 96-plus, that might matter less.

Cornelio’s best pitch is his mid-80s slider, which has tight, late, two-planed break and big length. Some of his well-located sliders are 70-grade weapons, but he throws a lot of non-competitive ones in the dirt or way off the plate. Solely honing his slider command would probably enable Cornelio to play a consistent middle inning role, as the pitch is nasty enough to front an up/down relief profile on its own.

Promoted to Rochester on 8/6/2025 after posting a 2.31 ERA / 0.98 WHIP at AA in 12 games / 66IP in 11 starts.

Convert him to a reliever now. That fastball serviceable if its 96

Great outing last night for the "Great" Conelio.

Nationals Player Development notes:
Quote
Riley Cornelio struck out 7 without issuing a walk in 6.0 innings of 3-run ball in @RocRedWings 4-3 win on Saturday night.

He leads Washington's system in ERA (3.08), opp. AVG (.204) and WHIP (1.12) and is 2nd in SO (117).

Thought he might be in the running for a call up instead of Alvarez. Cornelia needs to be added to the roster the offseason to protect him from the rule 5 draft.

Suggests a bullpen role, focusing on using his slider 50% of the time. best pitch. Notes he tires and loses fastball velocity, so shorter outings may help him maintain 96-97 on his fastball

Wondering if a new development staff can get his fastball to find another gear. Though he primarily uses his sinker/two seamer

Camerato's dark horse for the MLB roster:

Quote
Last Spring Training, Brad Lord rode the momentum of a single-season ascension in the Minor Leagues to make the Opening Day roster out of the bullpen (and eventually earned a spot in the rotation). Cornelio, 25, could be on a similar trajectory. Last season, Cornelio advanced from High-A to Triple-A and was named the Nationals Minor League Pitcher of the Year. After Cornelio led their farm system in ERA (3.28), opponents' batting average (.205) and starts (26), they protected him from the Rule 5 Draft. He is in camp as a member of the 40-man roster. -- Jessica Camerato

Riley Cornelio looks like 2026’s version of Brad Lord for the Washington Nationals

Coming off a breakout year, Riley Cornelio’s velocity has spiked this spring which is very reminiscent of Brad Lord
by Sam Sallick
Feb 25, 2026, 9:35 AM EST


Quote
Like Lord, Riley Cornelio was drafted in the 2022 class. He was taken in the 7th round, while Lord was selected in the 18th round. However, Cornelio’s breakout came a year after Lord. He gained three ticks of velocity according to Baseball America, averaging 94 on his heater.

The velocity gain led to much better results, with Cornelio posting a 3.28 ERA in 134.1 innings across three levels. It looks like the right hander has added even more velocity this spring, averaging over 96 MPH in his first outing of the spring. In his first inning of work, Cornelio averaged over 97, but he was sitting more in the 95-96 range in his second inning.

...
While the added velocity is the headliner for Cornelio, his fastball just sets the table for his best pitch. Riley Cornelio has always been known for his wipeout slider and he showcased that last night. He got five whiffs on the slider and threw it just as much as his fastball. Despite added velocity, Cornelio seems to be moving away from his fastball, a common trend in Nats camp.

Pitched well yesterday in his spring debut (except for a throwing error).

Another solid start. How is he not in our top-30?

https://www.milb.com/app-firstpitch/gameday/red-wings-vs-ironpigs/2026/04/07/816375/live
I think I read in Longenhagen's last chat that he would be looking at a few Nats affiliates this week while he was out east. I wonder if he caught this Cornelio start. If not, did he talk to people about him and upgrade his evaluation?

Its a small sample size, but they appear to have not only altered his mechanics, but significantly modified his pitch selection. Last year he threw a ton of sinkers and changeups. This year, his four seamer is a lot better and he throws it and the slider way more. Getting a lot of whiffs on the 4 seamer and slider
