Miller continued to develop across his sophomore and junior seasons, starting 13 games in 2018 and striking out 52 over 48 2/3 innings, then producing a strong junior year in 2019 with a 3.15 ERA and 97 strikeouts across 80 innings. He also competed in the Cape Cod Baseball League with the Orleans Firebirds, further sharpening his repertoire against top collegiate hitters.
