"He obviously opened some eyes," Yankees third baseman Alex Rodriguez said of Matusz prior to Wednesday's game. "I know that we were very impressed by him.
"For him to come in and have success that early just shows he's got a lot of potential. The Orioles definitely have a good one on their hands."
Matusz's dominance that game was particularly notable given the Yankees' dominance inside their brand-new stadium last season. New York went 57-24 at home, posting a .704 winning percentage.
"He really shut us down," Yankees manager Joe Girardi said. "You watch his stuff and he's got a very good changeup. It's always impressive when you have a young guy that comes up and pitches at an extremely high level. He did it at Yankee Stadium, where we played extremely well. That's even more impressive."
Matusz (2-0) will try to replicate that success when he takes the hill for Baltimore in Thursday's series finale. The 23-year-old, who still has rookie status, has won his last six decisions and is 7-2 in 12 career starts. Thursday will mark his second home start and the first time Matusz has faced the Yankees at Oriole Park.
