Hoyer said Monday that the move would be backdated to March 22, meaning Latos would be eligible to come off the DL on April 6. The Padres are scheduled to host the defending World Series champion San Francisco Giants that day.
Manager Bud Black said Latos "has turned the corner on this" and would play catch on Tuesday.
Latos, who was 14-10 with a 2.92 ERA last year, developed an inflamed bursa sac last week. Tim Stauffer is scheduled to start in Latos' place on opening day at St. Louis on Thursday.
