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

Anthony Gose, LHP, Detroit (Profile)
Level: Hi-A   Age: 26   Org Rank: NR   Top 100: NR
Line: 1 IP, 1 H, 1 BB, 1 R, 1 K

Notes
Gose hasn’t technically been a prospect since 2012, but he’s attempting to stick the landing on a Reverse Ankiel and convert to the mound after nine pro seasons as an outfielder. Gose’s inability to hit at the big-league level has sparked whimsical discussion about a conversion because he’s very athletic, was up to 97 on the mound in high school, and had some breaking-ball feel. His fastball was hovering in the mid- to upper 90s during extended spring training as he got up to speed for affiliated ball.

Diego Castillo, RHP, Tampa Bay (Profile)
Level: Double-A   Age: 23   Org Rank: 18   Top 100: NR
Line: 2 IP, 4 K, 0 H, 1 BB

Notes
I took umbrage with Castillo’s usage last year, noting that he didn’t pitch on back-to-back days, which might have inflated his elite-looking fastball velocity. Not only has Castillo thrown on back-to-back days this season, but he has several multi-inning appearances on his record now. He isn’t missing as many bats but that’s likely because his secondary pitches are mediocre, not because of velocity dilution. He’s throwing strikes (4% walk rate) and has a 2.28 ERA at Double-A — and, even though he only has middle-relief stuff, Castillo might be more valuable than that if he can work multiple innings. It appears he’s being groomed for such a role.

Jose Adolis Garcia, OF, St. Louis (Profile)
Level: Double-A   Age: 24   Org Rank: NR (had not yet signed)   Top 100: NR
Line: 3-for-3, BB, HR, CS

Notes
Garcia has homered in consecutive games, his first since April 20, and has looked exactly as advertised by international scouts before he signed. He’s a plus runner with plus bat speed, but he has swing-and-miss issues and his tools play down because of an erratic style of play. He continues to project as a fourth outfielder.

None today, as I spent Monday in the air on my way to Kentucky for the ACC Tournament.
