Prospect Spotlight

Heim was acquired as a PTBNL from the Rays in the Joey Wendle (2B, Rays) trade this off-season. He has returned to High A to begin 2018 and is poised to step forward to Double-A at some point this year. He’s known for his glove work, handling pitchers well, and showing polished receiving and defensive actions. Unfortunately his arm is below-average, but he’s nabbed an impressive 45% of would-be base stealers. He pops consistently around the 2.1 range, leaving pitchers vulnerable to basestealers who aren’t even true burners.

At the plate, he’s a switch-hitter with more power from the left side. Despite this, there’s significant length to his left-side swing, and he’s unlikely to make enough contact to bring consistent power into the offensive equation. He’s more of a contact-oriented hitter from the right-hand side of the plate, but inversely, there isn’t much potential to generate extra-base power when facing left-handed pitching.

He’s an intriguing profile as a tall, athletic, switch-hitting catcher, but the sum-of-the-parts still falls short of a regular ML role for me. The ceiling is a backup catcher off the bench.
