Chris Perez used three straight strikeouts to close out a win over the Nationals on Saturday.
The closer then used some more heat to criticize Cleveland fans.
"I was tired of getting booed at home so I figured, 'I'd better throw some strikes.' You can quote that," Perez said.
The first-place Indians rank last in the attendance in the big leagues.
Asked if it bothered him to get booed at home, Perez said, "It doesn't bother me, it p----s me off. I don't think they have a reason to boo me.
"They booed me against the Mariners when I had two guys on. It feels like I can't even give up a base runner without people booing me. It's even worse when there's only 5,000 in the stands, because then you can hear it. It p----s me off."
