Matusz pitched four hitless innings, struck out six of his first seven batters and retired his first 11 before a walk in Wednesday night's 9-4 win over the Minnesota Twins.
"My mindset was to attack the zone with authority and come out there and just play the game and pitch," Matsuz said. "Just build enough confidence. Just keep building, building and stay strong all the way through."
Matusz had a 10.69 ERA in 2011, the highest in a season for a pitcher with at least 10 starts. He was 5-10 with a 5.42 ERA in 16 starts last year, then was sent to the minors on July 1 after losing his fifth straight
Baltimore brought him back on Aug. 24, and he was 1-0 with a 1.35 ERA in 18 relief outings, holding opponents to a .114 batting average.
Chris Dickerson hit a solo home run in the third off Kevin Correia, who allowed two runs—one earned—and four hits in 4 2-3 innings.

Minnesota's Justin Morneau went 0
"He's one of the best hitters in the league for a reason," Matusz said. "He just keeps fighting. I felt like I was making good pitches. He was just putting good swings on it. That last pitch, I just said, I'm going to bury a slider here.' He's such a good hitter, he still put good wood on it. With those tough hitters, you've just got to bear down and throw strikes."
"It was something I'll never forget," he said.
Twins third baseman Trevor Plouffe remains out for at least several more days with a calf strain. Eduardo Escobar, who has just 59 games of big league experience, started at third and went 0 for 2.
"We've got all kinds of guys who can play third," Twins general manager Terry Ryan said. "It's just a matter of how much offense we'll get."
NOTES: Twins minor league RHP Deolis Guerra remains in Tampa in intensive care for a blood clot in his pitching shoulder. He is expected to have surgery within a few days. "This was precautionary," Ryan said. "This is something that a lot of people have had. We've had four guys ourselves. A blood
