Hideki Irabu joined the New York Yankees 14 years ago in a swell of international excitement. The quirky, flamethrowing Japanese right-hander seemed destined to become a pioneering star for American baseball's marquee franchise. Irabu never reached those enormous expectations, and his career spiraled. On Wednesday, the 42-year-old was found dead, an apparent suicide in a home in Rancho Palos Verdes, a wealthy Los Angeles suburb. "He was a world-class pitcher," said former major league manager and ESPN analyst Bobby Valentine, who managed Irabu in Japan in 1995. "When Nolan Ryan saw him, he said he had never seen anything like it. There were just some days when he was as good a pitcher as I had ever seen. A fabulous arm." Los Angeles County coroner's official Ed Winter said his office is investigating Irabu's death as a suicide, revealing no additional circumstances. An autopsy will be performed Friday or Saturday. Irabu was billed as the Japanese version of Ryan when he arrived in the United States in 1997, a hard-throwing starter with a 98 mph fastball who excelled as a strikeout specialist -- an almost unfair addition to the defending World Series champions.
