The Padres transferred Tatis (thigh) from the 10-day injured list to the 60-day IL on Wednesday.
Tatis has already missed more than 60 days with a right femoral stress reaction, so the transaction won't affect his timeline for a return. While Tatis has been participating in some baseball activities as he works his way back from injury, it's not clear when he might be ready to begin a minor-league rehab assignment. His move to the 60-day IL opens up a spot on the 40-man roster for infielder Mason McCoy, who was called up from Triple-A El Paso.
