Brian Matusz doesn’t want to be typecast as a situational left-hander. He’s much too young for that. At 26, there’s plenty of time for him to still establish himself as a major league starter despite the 2011 season that humiliated him. Fresh off his all-time major league worst 10.69 ERA, Matusz made the team as the fifth starter last spring, and when he was back in the minors for the second time in two years by midseason, it was time for a change. The Orioles made him a reliever, not out of choice, but out of necessity. Troy Patton sprained an ankle, and they desperately needed a left-hander. He was terrific in the last weeks of the 2012 season. That wasn’t good enough. He wants to start again, and on Wednesday night, he showed why he’s a contender to grab the fifth spot in the rotation. Matusz dazzled the Minnesota Twins for four innings, not allowing a hit and striking out seven of the 13 batters he faced. He punched out six of the first seven, and allowed just one baserunner, a fourth-inning walk to Josh Willingham in the Orioles’ 9-4 win over the Twins before 7,635 at Hammond Stadium.
