The Padres released Burdi (elbow) on Thursday.
Burdi opened the season on Triple-A El Paso's 7-day injured list before being activated April 19 and then optioned two days later without making a single appearance for the affiliate. The 29-year-old right-hander is apparently healthy again after undergoing his second Tommy John surgery in October 2020, but the Padres may not have been encouraged enough by his throwing sessions to justify keeping him around on the Triple-A roster.
