A rift between Mariano Rivera and Joba Chamberlain was quickly settled Sunday in the Yankees clubhouse, although Chamberlain saw no need to apologize for upbraiding baseball's all-time saves leader Saturday night.

"For what? It's over with, it's done," Chamberlain said. "It's really not an issue in the first place."

But Chamberlain apologized Sunday morning, according to Rivera, who insisted he wasn't angered by the 27-year-old right-hander's behavior.

"There's a lot of other things I have to worry about," Rivera said. "I'm better than that, guys."

Rivera, 43, had been speaking to a small group of reporters in the dugout Saturday, while Chamberlain was loudly talking nearby to family members in the stands.

After asking Chamberlain to quiet down, Rivera was chastised by Chamberlain. "Don't ever shush me," Chamberlain snapped at Rivera in front of reporters. Chamberlain added that he was serious.

"We joked and laughed after the game," Chamberlain said before Sunday's game against the Royals at Kauffman Stadium. "It was one of those things. I'm around him more than I am with my family. He's a brother to me."
