Conforto has been diagnosed with a Grade 2 left hamstring strain, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

The outfielder suffered the injury Wednesday in Philadelphia and was placed on the injured list earlier Friday. It's a moderate strain, which means Conforto is looking at longer than a minimum stay on the IL. Luis Matos is getting the start in right field Friday versus Atlanta and Heliot Ramos will fill Conforto's spot on the roster.
