Harold Castro had the distinct displeasure of being stuck on some of the Tigers' most lifeless teams, but he made the most out of it. Not necessarily in terms of performance — he had a -1.0 bWAR from 2019-2022 and a 90 OPS+, and his best season was 2020 — but he was a joyful player and an easy one for fans to root for during the team's fifth (2019-2020), third (2021), and fourth place (2022) finishes, when there was very little to get excited about.
He was non-tendered after the 2022 seasons and moved on to the Rockies.
