David Ortiz once again showed Japanese baseball fans his awesome power. In his first at-bat in Japan since 2004, the year he hit a 514-foot homer in the same stadium, Ortiz smacked a solo shot under the Tokyo Dome roof and over the left-field wall Saturday, as reported by the Associated Presss. That started the Red Sox to a 6-5 exhibition win over the Hanshin Tigers, the first of Boston?s four games on the trip. The World Series champions meet the Yomiuri Giants in another exhibition Sunday then play the first two games of the regular season against the Athletics on Tuesday and Wednesday nights.
