The Angels recalled Saucedo from Triple-A Salt Lake on Wednesday.
Saucedo will join the 26-man active roster as a replacement for fellow reliever Sam Bachman (forearm), who was placed on the 15-day injured list. Over six appearances out of the big-league bullpen this season, Saucedo has delivered a 5.40 ERA, 1.50 WHIP and 6:0 K:BB over 3.1 innings.
