Giants first baseman Rafael Devers apologized to manager Tony Vitello and said his actions at first base in the ninth inning of San Francisco's one-run loss to the Miami Marlins on Sunday are being "blown out of proportion."

Vitello backed his player, calling it a "nonissue."

After drawing a leadoff walk Sunday in Miami, Devers waved off pinch runner Jonah Cox and gestured angrily toward the dugout when the rookie came out. When first-base umpire Nate Tomlinson made the substitution official, Devers covered his face with his helmet and yelled into it. Upon reaching the dugout, he avoided a backslap from bench coach Jayce Tingler and headed directly for the clubhouse.
