Already mentioned Gaddis and Logan Allen, so everyone of note I saw besides them.
Lake County Pitchers
Tanner Burns - prototype in the organization for starting pitching to a T. Throws 4 pitches and throws them whenever he wants. Sound, athletic mechanics. Fastball sat 92-93, gets a lot of swing and misses with it because he locates it well. Throws a hard slider (the aforementioned slutter) up in the count, down in the count, whenever he wants and it has good late bite on it. Good curveball that falls off the table (he needs to tunnel it better IMO). Decent change up as a wrinkle when he sees guys for a 2nd or 3rd time. He's just solid everywhere, not outstanding with one thing. Exact way you can describe Bieber, Plesac, Civale, etc. as minor leaguers. He'll end the year in Akron.
Mason Hickman - a lot to work with with Hickman. Experienced college arm with typical traits looked for right now, but his size points to a higher ceiling coming. Right now sits 89-91, smooth repeatable mechanics which is great for a tall guy. He generates a ridiculous amount of drop on his fastball due to his frame and over the top throwing motion, which you don't really see in baseball with everyone worrying about spin rate and trying to "rise" their 4-seemers. Pairs that up with a 12-6 curve that works off of it. He also throws a slider as a wrinkle, but it's just that at this point. If they are able to strengthen him up a bit and optimize his mechanics and add 2-4 MPH, like they have with Bieber, Plesac, etc., and he keeps the vertical movement on his fastball then he becomes a big time prospect to watch.
Ray Burgos - often forgotten about from the 2016 draft, it was nice to see him live in game action post-injury finally. He was on a path to fly through the lower levels prior to him hurting his triceps in his throwing arm. He's smooth and low effort when he pitches, but because of his size is able to sit 92-93 with good life. His arm slot allows him to play a sweeping slider off of his fastball and he has the makings of an above average change-up, which is key for lefty starters to have nowadays IMO. He just needs to stay healthy, cause he is very talented. Guessing they will nurse him through this season and take it slow.
Relievers - there's just a crop of solid, but not spectacular from a prospect standpoint, relievers in Lake County right now. Kellen Rholl is a wrinkle the Indians target nowadays with a funky near side-arm lefty delivery but doesn't have big stuff. Kevin Kelly was solid and has multi-innings reliever potential if his swing and miss sticks. Tim Herrin is an intriguing lefty if he is able to dial his stuff in, mid-90s guy with a nasty slider that can K a ton of hitters. Nate Ocker hasn't shown what he showed in 2019 yet (velo is down), but some guys may take some time to get back to where they were, if they are even able to get to that point.
Said before the season started in this thread that this team is going to strike a lot of batters out. They're currently 2nd in their league in Ks as a staff, striking out 141 batters in 114 IP. This staff currently owns the second best ERA in the league at 2.84 as well. Just a solid pitching staff, but the highlights of the group are the 2020 draftees.
