2080 had a report on Adams.
Reading between the lines, sounds like this report wants to say:
40 hit
60 raw power
60 arm
50 defense (future)
+ slight plus for athletic build
+ slight plus for plate discipline
"Riley Adams, C, Univ. of San Diego | 2017 Draft Class
Ht/Wt: 6’4”/225 B/T: R/R Age (as of 2017 MLB Draft) 20y, 11m
A three-year performer at the University of San Diego, Adams shows off a lean athletic build including a high waist, wide shoulders, and long legs. He has present strength in his upper half, and he should be able to continue maturing physically without affecting his overall build or pushing him off the catcher position. He utilizes a relaxed stance, keeping his front arm tight to the body throughout the swing, allowing his hands to quickly attack the ball. The bat follows a short upward path, generating easy loft and backspin, and he flashes solid-plus raw power to the pull side during BP, with balls jumping to left-center field. While the swing works to help lift balls with consistency, the path can open up holes down and away, and he can show a willingness to chase off-speed pitches in the dirt when he falls behind (as evidenced in his five strikeouts in 16 plate appearances in a recent series against Santa Clara University).
Defensively, Adams showed many positives. Tall fore the position, he keeps a low target with a soft receiving hand and shows the ability to frame balls higher in the zone. He moves well laterally and is quick to smother and block balls into the dirt. Adams showcased an above-average arm against Santa Clara, taking a tough curveball low and away and putting it on the bag accurately to get a quick runner with a 2.0 pop time. He neutralized the run game all weekend, keeping balls in front of him and being quick to his feet after blocking. Though hitting just .255 through 26 games in 2017, Adams’s pop (.256 ISO) and ability to work a walk (.381 OBP) are each attractive qualities in a catcher and, combined with a solid defensive profile, those qualities could help to push him up draft boards this June. – Ryan Ozella"
