"I wasn't used to the game here, so that's why I had a lot of walks," Igawa said through interpreter Yumi Watanabe. "It was [my] first time pitching on the mound, that's the reason why [I walked batters]."
Igawa, who held batters to a .226 average this spring, said that he saw improvement in his changeup in his bullpen session on Thursday -- a pitch he often worked on during the Grapefruit League season.
"I plan to continue what I did in Spring Training and move forward from there," he said.
The Orioles send veteran right-hander Steve Trachsel to the mound for his first start of the season. Trachsel went 2-1 this spring with a 4.50 ERA in 26 innings of work, striking out eight and walking 10.
BAL: RHP Steve Trachsel (15-8, 4.97 ERA in 2006)
Trachsel will be making his Orioles debut in his first start of 2007. The 36-year-old won 15 games for the Mets last season and has a career 9-9 record and 3.58 ERA against the Yankees, holding the pinstripes' offense to a .227 average.
NYY: LHP Kei Igawa (Major League debut)
Igawa makes his first start in the Majors after a successful career in Japan that included three seasons as strikeout champion. Igawa posted a 2-0 record and 3.13 ERA in six spring starts, striking out 22 batters in 23 innings.
Player to watch
Orioles catcher Ramon Hernandez has always worn out Yankee pitching. He owns a .396 batting average against New York, with seven homers in 53 career at-bats.
