Daily notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Ryan Burr, RHP, Arizona (Profile)
Level: Low-A   Age: 22   Org Rank: NR   Top 100: NR
Line: 2 IP, 1 H, 0 BB, 1 R, 3 K

Notes
Burr was remarkably consistent at Arizona State, sitting 93-96 with an above average slider each time I saw him. After dealing with injuries last year, he’s back to missing bats, albeit at a lower level than one might like to see from a college prospect in his second full pro season. He has setup-man upside if everything is intact.

Ronald Herrera, RHP, New York AL (Profile)
Level: Double-A   Age: 22   Org Rank: 22   Top 100: NR
Line: 7 IP, 7 K, 4 H, 1 BB, 2 R

Notes
Lost amid a surfeit of talent in the upper reaches of the Yankees farm system is Herrera, who has an above-average changeup and command. Every other aspect of the repertoire is fringey, but Herrera is having success at Double-A (again) and projects as, at least, a valuable depth arm and possibly a back-end starter.

Carlos Cortes, OF, University of South Carolina
Level: SEC   Age: 19
Line: 1-for-2, HR, 4 BB, SB

Notes
Cortes is a stocky 5-foot-7. While he had one of the more intriguing bats in last year’s draft class, his size gave clubs pause about his pro prospects, and they wanted to see him hit in the SEC as confirmation of his ability to compete in something resembling pro ball. He has. He’s slugging .537 as a freshman and has 10 home runs. Cortes is a draft-eligible sophomore next year (he turns 21 a few weeks after the 2018 draft), and if he hits like this again next year, he’ll have answered a lot of questions about hitting for power at his size. Cortes projects in an outfield corner (where he throws left-handed), but he’s an ambidextrous thrower who can also play some second base.

Keston Hiura, 2B, UC Irvine
Level: Big West   Age: 20  Board Rank: 17
Line: 4-for-6, 2B, SB

Notes
Hiura is one of the best pure hitters in this year’s draft class, but scouts aren’t sure where on the defensive spectrum he’s going to fall because nobody has seen him throw this year and many anticipate post-draft surgery will be necessary. He’ll likely still be a top-20 pick.

Notes from the back fields
Clemson junior LHP Charlie Barnes has struck out more than a batter per inning in a large conference this year and looked solid yesterday, sitting 87-89 and touching 90 with an above-average changeup and two below-average breaking balls. The breakers play up against lefties because Barnes has a low three quarters slot. He looks like an up-and-down starter, but the body might have some room for a bit more velo. If it does, or if Barnes’ command really maxes out, he could pitch in the back of a rotation. Clemson CF Chase Pinder (brother of Chad) hit a leadoff homer and posted several plus run times yesterday on the first day of the ACC tournament.

North Carolina State SS Joe Dunand is an impressive physical specimen with big bat speed and power. He also has a 55 arm which will be sufficient when he, I think, inevitably moves to third base in pro ball. He showed bat control on one swing yesterday, but it was grooved on every other cut he took, and I’m not sure how much he’s going to hit.
