Scout’s note
A 12th-rounder who spent six seasons in the Rangers system before debuting in April 2026, Collyer has a 3.68 ERA across 22 big-league relief outings. The stuff grade got him on our board; the six-year climb is the part the box score doesn't show.
The Wire
▼ On the field: Reliever allowed two runs and a two-RBI single in a 13-1 loss after a prior scoreless outing, with one note he is very good but has issues lately.
