Casali will start at catcher and bat eighth in Wednesday's game against the White Sox, Alex Pavlovic of NBC Sports Bay Area reports.
Casali will start behind the dish for the third game in a row after going 3-for-6 with a walk, three runs and an RBI in the first two contests of the series. With Patrick Bailey (oblique) going on the injured list Tuesday, Casali looks poised to operate as the Giants' clear No. 1 catcher for the time being.
