This, coupled with an outing in which he gave up five runs in one-third of an inning to the Twins, prompted manager Mike Scioscia to say the Angels would "match up" in the ninth inning.
However, with a 7-5 lead in the ninth inning Friday, Scioscia called on Frieri, and the closer answered the call with his 26th save of the season.
"He got his confidence back, which is nice," catcher Chris Iannetta said. "It shows a lot of his character and what he's made of, to go through what he went through, then come back and nail it down for us."
Frieri never had any doubt.
"I knew that it was going to happen," Frieri said. "I knew I was going to go back to the Ernie that everybody knows. I just need to keep doing what I did last night, making pitches. Whenever I do that, I'm going to get people out."
Frieri struck out the side, working around a one-out double to Brett Lawrie, and regained his old mentality in the process.
"The first hitter I was trying to focus on just hitting my spot, not missing it," Frieri said. "And then I was like, 'Wait, wait this is not me, stop thinking so much and let it go.' After that, you could see I was a little more aggressive, and that's me."
