The Phillies optioned Shugart to Triple-A Lehigh Valley on Tuesday.
Shugart had a 3.25 ERA, 1.16 WHIP and 31:9 K:BB across his first 27.2 innings of the season, but he's being demoted Tuesday after surrendering three runs in both of his past two outings. The right-hander could get another look in the big-league bullpen later in the season, but for now he'll cede his roster spot to Lou Trivino.
