Nelson split his time between playing shortstop and
serving as the team's closer while he was a member of Oregon.
Nelson had to battle with an eye issue during the "lost 2020"
that ultimately necessitated surgery to reinforce the
collagen fibres in his cornea. He painstakingly spent 2020 fixing
on his relatively shaky mechanics in addition to the surgery.
Nelson went from being a questionable starter/reliever
prospect to a legitimate starting prospect as a result of
his health and mechanical advancements. Nelson's errant command was
discovered and brought under control once the modifications were made,
moving it from below average to just above average.
