Prospect to watch: Justus Sheffield, LHP. Sheffield, 22, posted a 2.56 ERA in 88 innings at Class AAA last year. His slider took a step forward and his changeup fades well, but he struggles commanding his two-seam fastball that has solid arm-side run. He likely starts the year at AAA with an early shot at joining Seattle’s rotation. He appears to be first in line if someone struggles or is injured.
