Shields will throw a bullpen session Friday instead of making a final spring start, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Shields finishes with a 3.45 ERA and a 12:7 K:BB ratio over 15.2 innings this spring and heads into the season as the team's number two starter. The right-hander will look to improve upon a miserable 2016 campaign with the Sox (6.77 ERA, 31 home runs allowed), beginning next Wednesday against Detroit.
