The Angels reassigned Strickland to Triple-A Salt Lake on Thursday, Jeff Fletcher of The Orange County Register reports.
Strickland had been in the hunt for a spot in the Angels' Opening Day bullpen while attending spring training as a non-roster invitee, but Anaheim ultimately couldn't make room on the 40-man and 26-man rosters for the journeyman reliever. His minor-league deal with the Angels doesn't contain an out clause, so he'll head to Salt Lake with the hope of performing well and eventually earning a call-up to Anaheim.
