Saucedo was optioned to Triple-A Buffalo ahead of Saturday's nightcap against the Orioles, Mitch Bannon of SI.com reports.
Although Saucedo wasn't used in Saturday's matinee, he'll head to the minors after Anthony Castro was recalled to provide an extra arm in the bullpen. The 28-year-old made 12 relief appearances during his stint with the major-league club, and he recorded a 7.20 ERA and 1.40 WHIP in 10 innings.
