For Orioles left-hander Brian Matusz, his first start of the season Monday night brings a new beginning — and a clean slate. Matusz, who earned the No. 4 spot in the rotation this spring, will make his season debut against the defending AL East champion New York Yankees. And the 25-year-old wants to use his first start as an official turning-of-the-page in putting last year's disastrous season behind him. "It's a fresh season," said Matusz, who went 1-9 with a 10.69 ERA last year and had two trips to the DL. "I don't even remember last year. I've totally cleared it out of my mind, and my focus is starting with a clean slate here and to get off on a good start."
