While Rivera, baseball's career saves leader, was conducting an interview in the dugout on Saturday after meeting some local families that had endured hard times, Chamberlain was signing autographs in front of the dugout and communicating rather loudly with family members in the stands in order to be heard over the public-address system.
Rivera did not like it and gestured to Chamberlain to lower his voice. According to The New York Times, Chamberlain went up to Rivera after the interview and said, "Don't shush me."
Rivera thought his team mate was kidding, but Chamberlain persisted, telling him "I'm serious. Don't ever shush me."
Rivera brushed off the exchange and said he would handle the matter internally with Chamberlain.
Chamberlain, who is on the disabled list with an oblique injury, said before Sunday's game against the Royals that there was no need to apologize to Rivera.
"For what? It's over with. It's done," Chamberlain said. "It's really not an issue in the first place."
