The Padres optioned Bachar to Triple-A El Paso on Monday.
The 29-year-old right-handed reliever received his first MLB call-up Sunday but didn't get the chance to make his Padres debut in the club's 3-2 win over the Mets before being sent back to Triple-A a day later. The Padres recalled right-hander Randy Vasquez from Triple-A in a corresponding move, and he'll start Monday's series opener in St. Louis.
