MLB ETA Risk Factor OFP Realistic Role Video
2018 High 50 40; back up Catcher Yes
Tool Future Grade Report
Hit 40 Switch hitter with same setup from both sides; plus bat speed; good swing path through zone; gets good post contact extension on pitches on the outer half; hands can drift at times; small hand movement in load; incorporates lower half well; showed advanced approach; showed ability to recognize secondary offerings but has present trouble barreling.

Power 40 Above average raw power; slight loft in swing; gets extended well; present power more visible from left side; inconsistency with hit tool will play power grade down in-game.
Baserunning/Speed 30 Timed in 4.4-4.5 range from both sides; heavy footed runner; clogger on the base paths; runs like a catcher.
Glove 60 Moves well laterally; shows strong wrist when framing; soft hands when receiving; footwork is strong allowing him a smooth transfer to throw; showed present ability to get low and provide the low target; can still improve his blocking skills overall.
Arm 55 Plus arm strength; pop times consistently in 1.90 - 1.95 range; accuracy is present strength but can get loose; footwork is clean and arm could grow stronger with potentially muscle; fast-twitch athlete.

Jonah Heim showed an advanced approach at the plate as well as plus catching tools. Heim will a defensive asset as he continues through the minors. He is a very projectable player and I think he will vastly improve at the plate. Heim received raves review from Buck Showalter about his catching abilities in spring training and they were well deserved. Heim will be a plus defender and just below average hitter allowing him to be a major league regular at the big league level.

Drafted: 2013 4th round, 129th overall
Why: advanced catcher as amateur; projectable frame; projectable hitter and power potential

Ceiling: Role 50; Major League Regular
