Kei Igawa pulled on his new pinstripes, stepped to the podium and threw his first change-up in the United States. His long hair freshly trimmed in accordance with team rules, the Japanese pitcher stood before a packed room at Yankee Stadium on Monday and explained -- in English -- how thrilled he was to reach the big leagues. "Today, my lifelong dream became a reality: to be a major league baseball player," Igawa said, reading carefully from a prepared statement. "I will give you my best as a Yankee. I will do my best to win the championship for this great city, New York."
