Fernando Tatis, Jr. suffered another injury to his troublesome left shoulder on a hard swing Monday and left the San Diego Padres' loss to the San Francisco Giants.

The Padres announced that Tatis exited because of a shoulder subluxation, which is a partial dislocation of the joint, and will undergo an MRI on Tuesday.

Jayce Tingler said that Tatis has experienced minor dislocations in the past but said that Monday's incident was the most pain he's ever seen Tatis in. Tingler also acknowledged that the nagging shoulder issue may have been bothering Tatis "more than we realized."
