The Reds optioned Schrock to Triple-A Louisville on Sunday, Bobby Nightengale of The Cincinnati Enquirer reports.
The Reds should get at least one of Mike Moustakas (illness) or Albert Almora (illness) back from the COVID-19-related injured list coming out of the All-Star break, so Schrock's demotion will open up a spot for a corresponding transaction. During his four-day stint with Cincinnati, Schrock went 0-for-2 while appearing off the bench in two games.
