Giants' Roberto Perez: Diagnosed with shoulder strain

Perez left Friday's game against Kansas City with a right shoulder strain, Maria I. Guardado of MLB.com reports.

While the severity of Perez's injury and how long he might be sidelined remain unknown, it seems as though the backstop avoided what could have been a much worse fate. Blake Sabol will assume primary catching duties while Perez and Joey Bart (back) work their way back from injuries.
